Humidity control

Refrigeration air conditioning equipment usually reduces the humidity of the air processed by the system. The relatively cold (below the dewpoint) evaporator coil condenses water vapor from the processed air, (much like an ice cold drink will condense water on the outside of a glass), sending the water to a drain and removing water vapor from the cooled space and lowering the relative humidity. Since humans perspire to provide natural cooling by the evaporation of perspiration from the skin, drier air (up to a point) improves the comfort provided. The comfort air conditioner is designed to create a 40% to 60% relative humidity in the occupied space. In food retailing establishments large open chiller cabinets act as highly effective air dehumidifying units.

Some air conditioning units dry the air without cooling it, and are better classified as dehumidifiers. They work like a normal air conditioner, except that a heat exchanger is placed between the intake and exhaust. In combination with convection fans they achieve a similar level of comfort as an air cooler in humid tropical climates, but only consume about a third of the electricity. They are also preferred by those who find the draft created by air coolers discomforting.

Air conditioning-History

While moving heat via machinery to provide air conditioning is a relatively modern invention, the cooling of buildings is not. The ancient Romans were known to circulate aqueduct water through the walls of certain houses to cool them. As this sort of water usage was expensive, generally only the wealthy could afford such a luxury.

Medieval Persia had buildings that used cisterns and wind towers to cool buildings during the hot season: cisterns (large open pools in a central courtyards, not underground tanks) collected rain water; wind towers had windows that could catch wind and internal vanes to direct the airflow down into the building, usually over the cistern and out through a downwind cooling tower^[2]. Cistern water evaporated, cooling the air in the building.

In 1820, British scientist and inventor Michael Faraday discovered that compressing and liquefying ammonia could chill air when the liquefied ammonia was allowed to evaporate. In 1842, Florida physician John Gorrie used compressor technology to create ice, which he used to cool air for his patients in his hospital in Apalachicola, Florida.^[3] He hoped eventually to use his ice-making machine to regulate the temperature of buildings. He even envisioned centralized air conditioning that could cool entire cities.^[4] Though his prototype leaked and performed irregularly, Gorrie was granted a patent in 1851 for his ice-making machine. His hopes for its success vanished soon afterwards when his chief financial backer died; Gorrie did not get the money he needed to develop the machine. According to his biographer Vivian M. Sherlock, he blamed the "Ice King," Frederic Tudor, for his failure, suspecting that Tudor had launched a smear campaign against his invention. Dr. Gorrie died impoverished in 1855 and the idea of air conditioning faded away for 50 years.

Early commercial applications of air conditioning were manufactured to cool air for industrial processing rather than personal comfort. In 1902 the first modern electrical air conditioning was invented by Willis Haviland Carrier. Designed to improve manufacturing process control in a printing plant, his invention controlled not only temperature but also humidity. The low heat and humidity were to help maintain consistent paper dimensions and ink alignment. Later Carrier's technology was applied to increase productivity in the workplace, and The Carrier Air Conditioning Company of America was formed to meet rising demand. Over time air conditioning came to be used to improve comfort in homes and automobiles. Residential sales expanded dramatically in the 1950s.

In 1906, Stuart W. Cramer of Charlotte, North Carolina, USA, was exploring ways to add moisture to the air in his textile mill. Cramer coined the term "air conditioning," using it in a patent claim he filed that year as an analogue to "water conditioning", then a well-known process for making textiles easier to process. He combined moisture with ventilation to "condition" and change the air in the factories, controlling the humidity so necessary in textile plants. Willis Carrier adopted the term and incorporated it into the name of his company. This evaporation of water in air, to provide a cooling effect, is now known as evaporative cooling.

The first air conditioners and refrigerators employed toxic or flammable gases like ammonia, methyl chloride, and propane which could result in fatal accidents when they leaked. Thomas Midgley, Jr. created the first chlorofluorocarbon gas, Freon, in 1928. The refrigerant was much safer for humans but was later found to be harmful to the atmosphere's ozone layer. Freon is a trademark name of DuPont for any Chlorofluorocarbon (CFC), Hydrogenated CFC (HCFC), or Hydrofluorocarbon (HFC) refrigerant, the name of each including a number indicating molecular composition (R-11, R-12, R-22, R-134). The blend most used in direct-expansion comfort cooling is an HCFC known as R-22. It is to be phased out for use in new equipment by 2010 and completely discontinued by 2020. R-11 and R-12 are no longer manufactured in the US, the only source for purchase being the cleaned and purified gas recovered from other air conditioner systems. Several non-ozone depleting refrigerants have been developed as alternatives, including R-410A, known by the brand name Puron.

Innovation in air conditioning technologies continue, with much recent emphasis placed on energy efficiency and improving indoor air quality. As an alternative to conventional refrigerants, natural alternatives like CO₂ (R-744) have been proposed.^[5]

How to Clean your Air Conditioner like a Pro???

Lets get started

1. Start by removing the filter from the front grille. If it is a disposable type simply replace it with a new one. Other types are made in a plastic frame and can be cleaned and reused. To clean a reusable type lay it flat in the sink and sprinkle surface with laundry detergent. Then cover with about one inch of hot water. Just enough so the filter is submerged. Soak for 15 minutes. Remove from water and rinse with warm water. Hang up to dry while proceeding to next step.

2. Next, remove the front grille from the main body of the air conditioner. They usually pivot on 2 spring clips at the bottom. It is usually removed by pulling the grille gently forward while pushing it down at the same time. If there is resistance then look for hidden screws. Look near the top edge of the grille or behind the control knob door. Once removed place the grille aside until later.

3. Carefully remove metal cover of air conditioner to expose inner workings. Once all the screws are removed lift the cover straight up. Do not let it hit the other parts as it can have sharp edges.

This is where the old can comes in handy (ice cube container or muffin tin works well also). Use it to keep track of all the screws you will be removing. An air conditioner will often use a number of different types and sizes of screws. Segregate them from each other or confusion will result when we start reassembly.

4. Check the fan motor for any oil holes or oil plugs. If the motor has oil plugs they are usually rubber. Use caution when removing because the rubber may have become brittle. Often they will break off in the oil holes resulting in a blockage. If this occurs try to remove the broken plug by using a pin, or the tip of a small screwdriver.

Once the fan motor oil holes are exposed add a few drops of oil to each end of the motor body. Use a general purpose (3in1) oil or clean motor oil. A #30 oil is sufficient.

The natural tendency is to over-oil. Too much lubrication is as bad as not enough. Therefore only 3 or 4 drops on both ends of the motor body is sufficient. Add the oil slowly, pausing a few seconds between each drop. If you add it too quickly over-lubrication will result.

5. Use the brush to remove surface dust and dirt from the evaporator (front fins). Use an up and down motion. Do not go side to side or allow the fins to be bent over. The fins are very soft aluminum and can be easily damaged.

Once surface dirt is removed, spray with de-greaser or cleaner. There is a good product on the market called HVAC cleaner. As the name implies it is meant for Heating, Ventilation, and Air Conditioner coil cleaning. If this is not available Fantastic spray cleaner used in kitchens and bathrooms works quite well.

Let stand about 15 minutes or as per instructions on de-greaser can. This will allow cleaner to loosen any hidden dirt. Remove dirt and excess cleaner by slowly pouring warm water into fins. Do not allow the water to enter any electrical connections or components that may be near the coil. As an added precaution cover the motor with one of the cloth rags. to protect it from the water.

Do not use any form of high pressure air or water because this can drive dirt farther into fins. Also, use extreme caution as these coils are filled with high pressure refrigerant.

6. Straighten any bent fins. Use a fin comb if available. If no fin comb then use something soft such as a Popsicle stick. Straightening the fins will increase the efficiency of the air flow through the coils. This adds to the overall cooling effect produced by the air conditioner.

7. Repeat steps 5 and 6 for the condenser (rear fins) coil. A plastic cowling usually surrounds the condenser fins. If so, check the top edge to see if it will lift or open. If it opens this will allow easier access to the condenser fins. Again use caution because the condenser coil is also filled with high pressure refrigerant.

8. Wipe any dirt buildup from both fan blades using a soft rag. Do not bend blades. This would cause a vibration that would harm the motor.

9. Vacuum all surfaces including front and back of grille assembly. Do not forget to vacuum underside of metal air conditioner cover. If the cover contains air holes clean them thoroughly. If necessary use a damp rag. Also use an old rag to remove any debris build-up from the base.

10. Drain any water left in the base and allow it to dry for few hours.

When completely dry plug in air conditioner and test operation. If everything appears okay unplug and reassemble.

Once reassembly is complete, retest operation to ensure replacing the cover has not affected anything. Adding the cover will tend to twist the frame and can cause interior parts to move out of alignment. This can cause the fan to become noisy. To correct for this problem remove the cover and realign to the main body of the air conditioner. Reinstall the cover and test for noises every time 2 or 3 additional screws are added to the cover.

Finally, cover air conditioner with plastic wrap or an old blanket. Store in a warm dry area. Raise it from floor slightly by placing onto a couple of pieces of wood. This will protect the floor from the metal edges of the air conditioner, and also protect the air conditioner from moisture.

ENERGY-SAVING AIR CONDITIONING TIPS

Air conditioning does more than cool the air. It truly "conditions" it by removing dust and dirt as the air is drawn through a filter. Air conditioning also lowers the humidity, making the air more comfortable at any temperature. These benefits, however, can be costly. Depending on your region of the country, air conditioning can account for anywhere from 5 to 50% of your household budget. Because an air conditioner is such a sizable investment, you can save money and energy by carefully purchasing and operating your air conditioner.

When shopping for an air conditioner, first consider what system best suits your needs - central air conditioning or room air conditioning. Central air conditioners are located in one part of a building, but they cool the entire building either by blowing cold air through ducts positioned in each room, or by circulating cooled water through pipes to each room where fans blow air across the pipes. Room air conditioners work in the same way, but have a smaller capacity and therefore only cool the immediate area.

Central air conditioners generally provide the greatest comfort but they also cost more than room units. If several rooms need to be cooled, however, a central system is probably the best buy. Central systems generally are not cost-effective as an addition to an existing home unless the existing ductwork can be used.

Room air conditioners are mounted in windows or built into an external wall. Room units are less expensive than central units; however, they only cool the general space in which they are located. There are three types of room units; window models can be installed in most windows; casement window models, used in narrow, vertical windows, usually require the removal of a window panel for installation; and built-in models which are encased in a sleeve installed in the wall.

Size

After selecting the optimum unit type, consider unit size. A bigger unit is not necessarily better, because a unit that is too large will not cool an area uniformly. Also, an oversized unit will cool an area too quickly, causing the air conditioner to frequently turn on and off. This wastes electricity and money. In addition, a unit that is too large will not run long enough to reduce humidity and, instead of feeling comfortable, the air will feel cold and clammy at the normal thermostat setting.

On the other hand, you should avoid purchasing too small a unit. An insufficiently sized unit will run constantly on hot days and still not be able to cool the area adequately.

In sizing an air conditioner for your home, consider the dimensions of the area to be cooled and how the area is used. Based on size alone, an air conditioner generally needs 20 Btu for each square foot of living space. For instance, to air condition a room that is 15 feet wide and 20 feet long, you would calculate: 15 x 20 x 20(Btu) = 6,000. Thus, an air conditioner with a 6,000 Btu capacity would be required.

Calculating Btu requirements becomes more complicated when you consider an area's use. For instance, if you use passive cooling techniques such as shading, ventilation or vegetation, your Btu estimate can be lowered. Likewise, your Btu needs are increased by factors such as the size of the household, frequent use of heat-producing appliances, or summer humidity levels. An appliance dealer will use these factors to adjust your estimated Btu requirement. For most efficient cooling, purchase a unit, with a capacity within 5% of this estimate.

How to Clean a Room Air Conditioner?

A room air conditioner that doesn't cool may need to be recharged with refrigerant--a task you should leave to a professional--but often just needs to be cleaned.

To clean the coils and filter:
* Unplug the unit. You may need to remove it from the window (be careful--it's heavy!)

* Remove the air inlet grill and remove the filter;

* Wash the filter or replace it with a disposable one;

* Vacuum the coils' fins with a soft brush attachment;

* Spray water back through the fins from the fan side (cover the wiring and motor with plastic);

* Check to be sure that the drains are clean;

* Lubricate the motor--check the owner's manual for instructions; and

* Reassemble and reinstall the unit.

Room Air Conditioner Problems and Repairs

Room air conditioners draw a lot of electrical power. If your air conditioner is not turning on, check for a tripped circuit breaker or blown fuse caused by an overloaded circuit. Also check that the thermostat to be sure it is set to cool and to a few degrees below room temperature.

If your air conditioner doesn't cool, you may need to clean or replace the filter, which might be restricting air movement. If that doesn't do it, clean the evaporator and condenser coils.

Room air conditioners can sometimes become very noisy. Check that the fan blades are not bent, and clean them. You may need to tighten the mounting bolts for the blower, which could be rattling in its casing, and lubricate the motor according to the manufacturer's directions. Also check that the unit's mounting bracket is firmly connected to the window or the wall; it too may be loose and rattling.

If you are working on a room air conditioner, clean the drains that allow condensed water to drip away from the unit.

Window Air Conditioner Problems?

Window air conditioners are usually plugged in and forgotten – until they stop cooling properly, or until they exhibit problems. Don’t just plug in your window air conditioner and ignore it. There are things you must do to properly maintain your window air conditioning unit in an effort to avoid problems. Taking proper care of your window air conditioner will ensure the unit will continue to provide the cold air you want when you need it the most. Don’t wait for problems to start before taking the necessary steps to keep your window air conditioner running properly.

The following information provides facts and tips on what you must do to avoid problems with your window air conditioner. Also included are troubleshooting tips for correcting common problems with window air conditioning units.

Preventing Problems

Any item that uses an air filter can’t run properly if the filter is dirty, and window air conditioners are no exception. If you want your window air conditioning unit to run properly and efficiently, it’s imperative that you change or clean the filter once a month.

The filter isn’t the only part of a window air conditioner that requires regular care and cleaning. The condenser coils can become covered in dirt and dust, and they should be cleaned at least once a year. Even if condenser coils don’t appear to be dirty, grime and dust can hide in places not readily visible.

While the air conditioner is unplugged and the condenser coils are dry, vacuum the coils with a crevice tool, blow away dirt and dust with an air compressor, or clean the coils with a soft brush such as an old toothbrush. This is an easy preventative measure that you can do yourself in an effort to avoid problems while lowering your electric bill in the process.

Type of Compressors, Key Features

TYPE OF COMPRESSORS

There are two important components of the window AC – the compressor and the Fan motor. The Compressor consumes 90 percent of the electricity whereas the fan motor consumption is only 10 percent. The compressor is backbone of the air conditioner as this is the component that causes cooling. It compresses the gas causing it to become hot, which is then condensed into a liquid through a set of coils. This cools the air around it. There are two types of compressors used in window ACs – reciprocating and rotary.

Reciprocating compressor - It compresses the air by sliding the piston over the cylinder. Air conditioners fitted with a reciprocating compressor are generally less expensive but are not as efficient and silent as the ACs with the rotary compressor.

Rotary compressor - This compresses air by centrifugal action of high-speed impeller in a confined space. This method reduces the loss in pressure of the refrigerator gas. Rotary compressors are more efficient and silent. Buying an energy efficient compressor will save on your electric bills in the long run.

The rotary compressor is expensive as compared to a reciprocating compressor, however, it makes up for that cost by saving more on power as compared to a reciprocating compressor.

KEY FEATURES

Energy efficiency ratio (EER)

Energy Efficiency Ratio measures the cooling efficiency of the air conditioner as compared to the power it consumes. It is the ratio of the cooling capacity in BTU/hr to its electricity consumption in watts. Models with a higher EER save on your electricity bills but are priced a little higher than ones with lower EER. An EER of nine and above is considered good.

Filter

A filter purifies the air that goes through the air conditioner. There are different types of filters that remove dust, germs, bacteria, odour, etc. Deodorising filters remove dust particles and dirt; anti-fungal filters clean the air and remove germs and bacteria thus reducing respiratory problems. The Electrostatic filter releases positive ions, which ionise the negative ions of dust and static electricity giving you a clean, dust free environment. Slide-in and Slide-out filters allow easy maintenance as they can be removed for cleaning without opening or dismantling the entire machine. If you smoke or live in an air-polluted area that is prone to dust, this would be an important feature to consider.

Anti corrosion body

The body and framework of air conditioners is prone to corrosion especially as one part of it is outside and is exposed to rain, moisture, dust, etc. However, if the exterior is made of galvanised steel or is powder coated it helps in protecting the unit from corrosion and extends the life of the body.

Auto restart

If there is a power failure or if the air conditioner has been disconnected, you may have to reset and programme all the cooling functions and features that you originally had. An air conditioner with the auto restart facility starts automatically and restores the original settings when the power is restored. This feature is beneficial in areas where power supply is irregular.

Remote control

Don't need to go into why this is useful but it becomes a must-have if your AC is placed at a height. Of course, most of us cannot imagine an appliance without a remote control, as it would mean having to get up each time to change settings.

Timer

The timer lets you to set the air conditioner to begin cooling at any time, whether you are home or not. It is also helpful to shut off during the middle of the night when it gets very cold.

Noise

Air conditioners with rotary compressors generally make less noise than a reciprocating compressor. The noise level in a window AC ranges fro 40 to 60 db. The lower the better, however, higher the capacity of the air-conditioner, more the decibels.

These are few things that you need to be informed about before deciding upon a window AC. For more information on the various brands available in the market click here.

Airconditioners (Window)

Rising temperatures, low prices, improved efficiency are making window air conditioners a very attractive proposition. Of course, the manufacturers also realize this and so have bombarded you with dozens of models to pick from. Clearly you're spoilt for choices. Hopefully, this guide will help you make an informed choice.

Before you get into the brand or company you want to buy an AC from, you need to have figured out basics like how much cooling you will want (capacity), how much you are willing to invest on this (budget) and what else you would like your AC to have (additional features – remote control, display, etc).

COOLING CAPACITY

Most air conditioners are rated in BTU per hour (British Thermal Unit) or by tonnage. One ton is equal to 12,000 BTU per hour. The cooling capacity that you need would depends on a number of factors like number of people in the room, number of appliances in the room, etc. The average ambient temperature of your area during the year: Higher the average temperature of the outside air, the more will be the cooling capacity required. If you live in a cities which have scorching hot summers, you will need an AC with higher cooling capacity.

ROOM SIZE

The cooling capacity required is proportional to the area of the room you wish to cool. A bigger room will naturally require a higher ton AC as compared to a smaller room. Also if you have a bigger family, five or more people and everyone will crowd into one room, then the capacity will have to be higher even though the room may be small. Also, your capacity will need to be higher if any of your walls gets a direct blast of sunlight, so as to negate the heat from the sun. The hottest room in your house is your kitchen, so if the AC room is next to the kitchen then a higher cooling capacity is advisable.

Rooms Size (Sq ft)	Tonnage Capacity
Up to 90 sq ft	0.8 Ton
Up to 120 sq ft	1.0 Ton
Up to 180 sq ft	1.5 Ton
Up to 220 sq ft	2.0 Ton

BUDGET

A one ton window AC starts from as low as Rs 9,700 and can go up to Rs 31,490. You may already have a budget in mind as to how much you would like to spend. Window Air Conditioners range from Rs 9,700 to Rs 31,490. The cooling capacity and features affect the price.

Price range

0.6 Ton - 1.0 Ton	Rs 8,990 - 21,600
1.1 Ton - 1.5 Ton	Rs 13,495 - 24,600
1.6 Ton - 2.0 Ton	Rs 16,200 - 32,990

Main Features
Cooling Capacity (Tonnes) What it means? It is the capacity to cool the air in the room and is generally measured in Tonnes (or Tons). The tonnage of an airconditioner depends on its BTU/hr (British Thermal Units per hour) value. How it works? As a thumb rule, divide the square feet area of your room by 600 to arrive at the basic tonnage capacity required. Add 0.5 tonnes for every 10 people occupying the room at the same time. Similarly add 0.5 tonnes for every 1500 watts of appliances or lighting present in the room (A computer would consume about 300 watts and a regular bulb, 40 to 60 watts). Always round off on the higher side. However, this calculation is very subjective and each manufacturer has his own calculations for measuring required tonnage. Very often manufacturers calculations suggest a number that is very high and your own discretion is required when you actually decide to buy. Benefits Choosing the correct cooling capacity helps reduce your electricity bills. A larger air conditioner than what is required not only costs more but cools too quickly, switching on and off at very short intervals. This leaves the room unpleasantly cold and humid. On the other hand an air conditioner that is small for the room will take a longer period to cool the room and will not give very good results.	1.5
Power Consumption (Watts)	1850
Energy Efficiency Ratio (EER) What it means? Energy Efficiency Ratio measures the cooling efficiency of the air conditioner compared to the power it consumes. How it works? It is the ratio of the cooling capacity in BTU/hr to its electricity consumption in watts. Benefits It is in your best interest to buy machines with higher EERs as they are more energy efficient and can save on electricity consumption.	9.73
Compressor
Compressor Type What it means? Compressor Type states the type of compressor that your air conditioner has. They are of two types: reciprocating or rotary. How it works? The compressor in the AC circulates the refrigerant through all the refrigeration system parts to provide uninterrupted cooling in the room. Compressor is the most important part and is often called The Heart of the refrigeration system. There are of two types: reciprocating or rotary. Benefits Rotary compressors are silent and generate less vibrations as compared to reciprocating compressors. Reciprocating compressors are generally less expensive and not as power efficient and silent as the ones fitted with a rotary compressor. Rotary compressors are not repairable, when the failure occurs out of warranty period. Reciprocating compressors are repairable – mostly by respective compressor manufacturers in India.	Rotary
Refrigerant Gas What it means? The refrigerant gas is the substance that flows through the various components and coils of the air conditioner such as the evaporator, compressor and condenser to remove heat and cool the environment. The weight of the refrigerant (measured in grams). R-22 is a long-time standard refrigerant used in cooling products.	---
Fans
Number of Fan Speeds Available What it means? The number of settings at which the fan of the air conditioner can operate (just like the regulator of a ceiling fan). Benefits More fan settings are preferred as it gives the user a wider choice of speeds at which the air conditioner blows the air.	2
Maximum Fan Speed (rpm) What it means? It is the maximum speed at which the fan can possibly rotate. How it works? The speed of the fan is measured in RPM (rotations per minute). A higher maximum speed indicates that the air conditioner is able to blow a stronger stream of air into the room.	---
Air Circulation and Moisture Removal
Air Circulation (High) (CFM)	480
Air Circulation (High) (M3/Hr) What it means? Air flow is the circulation of cold air from the machine. It is measured as M3 per hour. Higher the air flow or circulation better is the cooling.	---
Moisture Removal (Ltrs/Hr) What it means? It is the ability of the air conditioner to remove moisture from the air as it cools. Benefits This makes the room more comfortable and decreases humidity. This is one of the reasons why air conditioners are so effective in humid areas and preferred over air-coolers which are used in the dryer regions of interior and western India.	2.3
Filters
Filter Type What it means? A filter purifies the air that goes through the air conditioner. Slide in/ Slide out filters and Pop-up filters allow easy maintenance as they can be removed for cleaning without opening or dismantling the entire machine. How it works? There are different types of filters, which remove dust, germs, bacteria, odour, etc. Deodourising filters remove dust particles, dirt, and tobacco smoke and absorb odour-generating particles. Anti bacterial and anti fungal filters clean the air and remove germs and bacteria thus reducing respiratory problems. The Electrostatic filter removes dust particles as small as 0.01 microns cleaning the air of dirt, dust and tobacco smoke etc. The Ionisation filter restores the balance between postitive and negative ions, thus reducing domestic pollution. Benefits Filters help to improve air freshness. It is very necessary that the air conditioner you choose not just cools the air, but also cleans the air. Go in for air conditioners that have built-in deodorizer and special filters that remove bacteria and dust.	Slide-in/out
Deodourising Filter What it means? It is a type of filter. It absorbs smoke and odour-generating particles like tobacco smoke, etc. Leaves the room smelling fresh.
Anti Fungus or Bacteria Filter What it means? It is a type of filter. Filters clean the air as it flows through the airconditioner. The anti-fungal filter removes bacteria and fungus present in the air. Benefits This is a boon for people with respiratory problems and those who live in humid areas.
Electrostatic Filter What it means? It is a type of filter which gives particles of dust electric charge. This causes particles to be attracted to a plate so they can be removed from air stream or atmosphere.
Ionisation What it means? It is a type of filter which cleans the air from smoke, dust and germs. Filters clean the air as it flows through the airconditioner. Ionising Filters generate negative ions which combine with positive ions in the air to give clean air, free of smoke, dust and germs. Benefits Helps to keep the room smoke-free thus keeping the air in it smelling fresh.
