Written the major three types of compressors are:-Reciprocating Air Compressorspositive displacementRotary Screw Compressorspositive displacementCentrifugal Compressorsdynamicrotating impellerWritten For air conditioning, we can compare as follows:1) Rotary compressors make lot of noice, and needs proper maintaince.2) Reciprocating compressors also make lot of noice, and needs proper maintaince.3) Scroll compressors are compact, easy maintenance, and less noise pollution.Therefore scroll compressors are better to prefer.Written the major three types of compressors are:- Reciprocating Air Compressorspositive displacement machines, - they increase the pressure of the air by reducing its volume. i.e they are taking in successive volumes of air which is confined within a closed space and elevating this air to a higher pressure  Rotary Screw Compressorspositive displacement compressors. The most common rotary air compressor is the single stage helical or spiral lobe oil flooded screw air compressor.

These compressors consist of two rotors within a casing where the rotors compress the air internally  Centrifugal Compressors dynamic compressor which depends on transfer of energy from a rotating impeller to the air.They  produce high-pressure discharge by converting angular momentum imparted by the rotating impeller (dynamic displacement).Written Reciprocating compressors are having high vibrations, Scroll is difficult to repair.My personal choice for fixed displacement compressors is Rotary Vane Type Compressor as it has high efficiency and less vibrations.However, Variable displacement compressors (VDC) or Electronics (read inverter technology), which supports compressor to work on different speed, offers even better efficiency.For home / small office, look for inverter AC. You may opt for Hitachi, Mitsubishi or Panasonic for Inverter AC.For car, AC must be with VDC (Variable Displacement Compressor). Sanden Vikas is the top manufacturer of VDC. Cars like VW Vento, Polo, Maruti Swift Diesel, Fiat Punto, Linea, Renault Duster, Nissan Terreno, M&M TUV300 and Bolero have VDC compressor.

All of these vehicles have Sanden VDC compressor.VDC offers higher efficiency, clutch-less operation (no noise or jerk), no ON-OFF operation.Inverter AC and VDC Compressors (for car) offers very high efficiency and performance. air conditioning unit ice upThey are expensive (by 15~20%) but payback is between 6 months to 2 years only, depending on the usage.ac unit cooling slowlyWritten Air conditioner compressor is used to remove the heat-laden vapor refrigerant from the evaporator of the air conditioning systems. carrier ac unit dimensionsBasically two types of compressors preferred for Air Conditioners and they are Reciprocating or Piston Air Compressors and Rotary Air Compressors.By observing the market, I have seen that most of the air conditioners brands have reciprocating compressor whereas there are some brands, having rotary compressor, which are quite popular with the customers who are looking to buy air conditioners for a large space.

Going by the typical choices of consumers, if you are looking to cool a large area for a long time or you plan to use your air conditioner continuously for hours at a stretch like at a commercial space then going for a rotary compressor would be a good idea.Or else, if you need the air conditioner just for your house or a small office or a shop, where your usage wouldn’t be as high as in an industrial or commercial space, then reciprocating air compressors seem to be a good option. Both types of compressors are good if they are of good quality. That is why most Air Conditioner manufacturer use Eaton Compressors because they are durable and highly efficientAir conditioners have found very high applicability in the current scenario of temperature increase all over the world. There are various parts to an air conditioner which when function in cohesion to produce a cool and comfortable environment within the room. In this article, we will try to understand about a particular component of an air conditioner: Compressor.

How a compressor contributes to the whole process of air conditioning, different types of compressors and which one should you go for while choosing an air conditioner. Air conditioners house three components which play a crucial role in the entire process of air conditioning. These are: compressor, condenser and an evaporator. The incoming air goes through all these components and comes out cool and comfortable. Out of these components, the compressor plays the role of compressing the refrigerant to a high pressure and converting it to a high pressure, high temperature liquid which is then passed on to the condenser which takes the heat out of the liquid and releases the heat to the surroundings. The high pressure liquid air is finally passed through an expansion valve which does the function of converting the liquid refrigerant to gas and then dispensed through the evaporator into the room. It is evident now that compressors play a very important role in the air conditioning system.

The proper compression of the refrigerant gas to a high pressure liquid is ensured by the compressor. There are different types of compressors for air conditioners available in market. Let us find out. The following two types of compressors are quite popular now-a-days. 1. Reciprocating (piston) air compressor: These compressors have an arrangement of cylinder and piston which is quite similar to the engine of an automobile. The piston has a “back-and-forth” motion which first compresses the gas and then discharges it. (See the diagram below) 2. Rotary air compressor: A typical rotary air compressor consists of a pair of rotors of a special design having very little clearance between each other. These rotors rotate in opposite directions and the air is passed through them to emerge at a higher pressure than before. There are some other kinds of air compressors as well like screw compressors, centrifugal compressors and,scroll compressors. But these are not as popular as the ones mentioned above.

After seeing both the compressors, the question which comes to one’s mind is: Which one should I opt for while buying an air conditioner?. For answering this question, here we are listing the pros and cons of both the types of compressors. 2. Works well at high pressures 1. Produces a noise and vibrates 2. High temperature of the air coming out 1. Works well for big offices and industrial setup 2. Produces lesser noise than the reciprocating air compressors 3. Lower temperature of the out-coming compressed air 2. Minimum amount of air-usage per week/day is required and that is why it is ideal for offices. It is observed that there is a minimum amount of usage that is required in rotary air compressors to prevent the formation of water condensate which in turn leads to the problem of corrosion. Thus understanding the above factors, the choice for the right air compressor depends on the requirements of the consumer. So it is important to understand one’s requirements before choosing a particular compressor.
