Reciprocating piston compressors are most often seen for high-pressure / low flow applications (up to 30 bars), while rotary screw compressors are used for continuous applications (high flow, 7 or 8 bar).. How Refrigerant gas converts into a high-pressure liquid is determined by the compressor itself. The usage of the air conditioner is very vital before selecting the type of compressor. And then, the temperature of the warm liquid decreases gradually. 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. Despite its ability to cool larger quantities of air, a rotary unit is actually less expensive than a scroll compressor. The clearance between the blades is very less. Difference between Centrifugal and Reciprocating Compressor This article lists a few of the differences between a centrifugal and reciprocating compressor. The principal function of the compressor is to draw the cool, low-pressure refrigerant gas and compress it thereby converting increasing its temperature and pressure resulting in the release of a hot, high-pressure gas. Fewer parts make the scroll compressor energy efficient, highly reliable, and less prone to mechanical failure. Before going further about the Reciprocating vs Rotary compressor, lets see the basic principle of an air conditioner. Because of that, the refrigerant gets converted to a liquid but the pressure remains high. This difference in pressure forces the cylinder door to open and bring gas in. An air condition usually functions on three main functions that include compress, condensation, and evaporation. !

A reciprocating compressor has its piston to move up and downwards, the movement helps to reduce the pressure in its cylinder by creating a vacuum. These compressors work like automobile engines. They are much suitable for a small space like your house. The compressor is used to expel heat out of the room by compressing refrigerant coming from the evaporator of the AC. Scroll Compressors are More Efficient Scroll compressors run quieter and smoother than reciprocating compressors because they only have two moving parts: a fixed and orbital scroll. The compressor is run by a motor. All refrigerators or air conditioners have mainly three components, the compressor, condenser, and evaporator(s) along with an expansion valve to reduce the pressure of refrigerants. An Air Conditioner has a wide variety of parts, which together make the room atmosphere cool and comfortable. Most common pressure is 7 to 8 bars. A reciprocating compressor has a piston move downwards, reducing pressure in its cylinder by creating a vacuum. 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 comparison is studied based on various parameters like maximum and minimum flow, Inlet and outlet pressure, efficiency, Compression ratio, discharge temperature, Flow range, materials of construction, cost, etc.. Ultimately, the choice between a rotary or reciprocating air compressor should be based on how often you intend to use the compressor and to what extent. Compression Any AC unit has three main components, the compressor, condenser, and evaporator. Thanks for your subscription. And thereby extract the heat of the room and transfer it to the outside air. While the refrigerant leaves the expansion valves, it is low pressure and low-temperature liquid. These rotors rotate in opposite directions, and hence the air comes out at high pressure when it emanates through the rotors. You may compare the compressor of an AC with the heart. To answer this question, we are listing here the pros and cons of both types of compressors so that it can help you in making the right decision. Fluid compressed by reciprocating motion of piston. Media Credit : Featured Image –Photo by Mak on Unsplash, Get Exclusive Technical Guides And News Directly To Your Inbox. The reciprocating in my experience is more reliable than rotary. In the evaporator, the liquid refrigerant absorbs the heat again and converts itself into a low pressure, high-temperature gas, the cycle then continues like that. Reciprocating compressors contain a mixed system of a cylinder and piston similar to an engine of a vehicle. In the compressor, the refrigerant gas is pressurized with the help of the compressor motor and thus increases the pressure and temperature of the refrigerant. Let’s find out the Difference between reciprocating vs rotary compressor in this article. This whole concept of conditioning the air is called HVAC ( Heating Ventilation And Air Conditioning). Rotary compressors are suitable for large-scale cooling such as industries, offices, or factories. We believe the difference between reciprocating vs rotary compressor is clear to you.

Apart from the reciprocating compressors and rotary compressors, there are some other types of compressors such as scroll compressors, centrifugal compressors, and screw compressors. Rotary compressor basically operates with a minimal vibration and less heat unlike the piston compressor. Rotary Compressor consists of specially designed rotors. That is how the refrigerant completes the cycling and turns into a low-pressure gas. Another difference is that oil is used to seal the gaps between the rotary’s screws during compression while the reciprocating pumps have piston rings that will eventually wear out. This heat is transferred via radiation and conduction to liquid accumulator and keeps it warm. The primary function of the compressor is to move the cool, low-pressure, refrigerant gas. Rotary compressors are more visible to us at large offices and industrial sites, these compressors are considered suitable for large space only. It offers higher efficiency than reciprocating compressors due to less losses from the clearance volume between the piston and the compressor casing, its 40% to 50% smaller and lighter for a given capacity (which can impact material and shipping costs when used in a product), causes less vibration, has fewer components and is more reliable than a reciprocating compressor. If you don’t know about refrigerant, then you should read the below article first and then come back to this article. An ideal rotary (cyclic) air compressor, consists of a pair of rotors of a unique design, with the couple having very short distances between each other for clearance. The fans of the AC unit take over as they blow cold air over the coil. The reciprocating compressors work on the cylinder and piston arrangement.
