Reciprocating vs Rotary Compressor – Know The Difference! You may compare the compressor of an AC with the heart. There are different type of compressor used in an ac. An Air Conditioner has a wide variety of parts, which together make the room atmosphere cool and comfortable. These rotors rotate in the opposite direction of the inlet of the compressor. But you will see that domestic air conditioners always come with reciprocating compressors. That is how the refrigerant completes the cycling and turns into a low-pressure gas. While purchasing an air conditioner, it is very important to understand the compressor carefully. Let’s find out the Difference between reciprocating vs rotary compressor in this article. Apart from these two types, these are the other types of compressors that are commonly known, like screw compressors, centrifugal compressors, and scroll compressors, etc. Compression Any AC unit has three main components, the compressor, condenser, and evaporator. We have given our best to provide every piece of information on both rotary and reciprocating compressors. And thereby extract the heat of the room and transfer it to the outside air. The compressor compresses the refrigerant, which flows to the condenser, where it gets cooled. Read More. In most cases rotary screw compressor packages are equipped with a starter, aftercooler, and compressor controller with diagnostic capability as standard equipment. Rotary compressors are more better than reciprocating compressors as they provide high mass flow rates and high pressure rations. Due to its design, the rotary’s casing working temperature is about 100°C. Difference between Reciprocating Compressor and Rotary Compressor ... Rotary compressor. Thus it can easily suck air. However, These compressors are not as popular as compared to the compressors mentioned above. 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 pass… The other significant difference between the two is that rotary usually screws air compressors while the reciprocating compressor operates with lower dBase. It can be a single-stage compressor for a home air conditioning system and a double stage compressor for large scale industrial use. How Refrigerant gas converts into a high-pressure liquid is determined by the compressor itself. These are: compressor, condenser and an evaporator. Refrigerant is like blood—just as blood absorbs and circulates oxygen throughout the body, the refrigerantabsorbs heat from the room and circulates it outside in the surrounding. One key difference is that reciprocating compressors use pistons while rotary compressors do not. There are various types of compressors used in the refrigeration and air conditioning machines, these are: reciprocating, rotary, screw, centrifugal and scroll. Home > Air Conditioner > Reciprocating vs Rotary Compressor – Know The Difference! The AC compressor is a mechanical device that reduces the volume of gas to add pressure while the AC condenser takes in the pressurized gas turning it into a liquid-vapor. When we analyzed and researched the difference between Rotary and Reciprocating Compressor in the market, we found that most AC brands are equipped with reciprocating compressors, while some air conditioner brands have a rotary compressor. Now we have seen that a compressor plays a major role in the entire air conditioning system. In India, we all are familiar with the extremely hot summers. Both compressor types have their own advantages and disadvantages. Media Credit : Featured Image –Photo by Mak on Unsplash, Get Exclusive Technical Guides And News Directly To Your Inbox. Prime mover (motor or engine) and compressor is separated, so … Due to the low temperature, it can easily absorb the heat and goes to the compressor. The price difference is passed on to the cost of the overall air conditioning unit or systems, which can become a deciding factor when choosing your unit. Therefore it is very important to understand your requirements properly before choosing a particular compressor for air conditioners. These rotors rotate in opposite directions, and hence the air comes out at high pressure when it emanates through the rotors. This entire cycle continues to repeat to supply a continuous flow of cool air in the room.
