how many types of compressor

An expansion device is thus needed to expand the liquid refrigerant and reduce its pressure to the value at which evaporation occurs. The 5 Types of Air Conditioning Compressors Inside each air conditioning unit is a compressor. They received their names from the actions of their mechanical parts: Piston compressor has the piston travels back and forth in the cylinder. Here are the five types of compressors is most commonly used for mechanical cooling. There are a few types of air compressors to choose from and they differ based on how each one of them compresses air. Easy maintenance. Therefore, the compressor has the function of circulating refrigerant inside the circuit, drawing it in as a gas from the evaporator and then compressing it and delivering it at higher pressure to the condenser. Most air compressors rely on oil to lubricate the inside mechanisms, and the fumes may contaminate the air, which could result in damage to products or manufacturing processes. Most of … Single-stage and two-stage reciprocating compressors are commercially available. Multiple compression trains are normally supplied in parallel to achieve total flow and head requirements of a specific application. The compressor may has more than one cylinder which is also known as multicylinder compressor. Diaphragm In line Compressors. The compressor starts working when the unit needs to provide cooling, and is usually activated via temperature control systems. Scroll. This type of compressor can have high performance up to almost 43 м³ / min, and operating pressure in the range from 5 to 14 bar. These essentially differ as regards the way compression is achieved, with reciprocating compressors featuring a reciprocating movement to create compression, and rotary compressors, including rotary vane, scroll, screw and centrifugal compressors, featuring a rotational movement to bring about compression. What is Optical Compression? A scroll compressor has one fixed scroll which remains stationary and another moving or orbiting scroll that rotates through the use of swing link. Rotary Compressors. A sliding-vane compressor relies on a series of vanes, mounted in a rotor, which sweep along... Scroll Compressors. If you transport your air compressor between sites, a portable unit is a good option. This compressor is presented in two different ways. An electric motor or gasoline engine drives a piston, which compresses air and forces it into a storage tank. FET (or Field Effect Transistor) compression came about when audio units... 2. The four most common types of air compressors you will see are: We’ll cover what each is best used for below, so you can make an informed decision for your project. The compressor compresses the refrigerant, which flows to the condenser, where it gets cooled. However, the various compressor types and their attributes often cause confusion for data center managers and operators. As to which type is the best one to use, it all depends on every person’s needs. Though oil-free compressors are generally more expensive, they are the only option for facilities that guarantee clean manufacturing.

Understanding how the various types of compressors work will likely prove helpful when that time comes. Rotary compressor-center rotor, which rotates inside the cylinder. so that the condensation process can take place at a temperature that’s compatible with a readily available “cold” source, typically the outside air. If you’re working on a long construction project, getting the most energy-efficient air compressor can be worth the extra cost in the long run. There are two types of motors that run air compressors -- electric and gas. As gases are compressible, the compressor also reduces the volume of gas. Compressor performance has a large influence on total engine performance. Advantages. When blowing out a sprinkler line, there's usually a lot of water around. The compressor plays the very important role of compressing the refrigerant as it enters the machine in order to increase its temperature. Energy is wasted during this cool-down period as the compressor is still running, but no power is being generated. In certain industrial settings, a natural gas compressor works well to power tools and equipment. The compressors are one of the most important parts of the refrigeration cycle. Because of the multi-phase compression process, centrifugal compressors are able to produce a high amount of energy in a relatively small machine. Positive displacement compressors cab be further divided into Reciprocating and rotary compressors. 1. If you think you will need any of these additional features, you will want to make sure that the types of air compressors you choose will be compatible with these tools. These units run on natural gas instead of diesel or electricity. This thermodynamic cycle exploits the evaporation of a refrigerant inside a closed loop piping circuit. There are various types of compressors used in the refrigeration and air conditioning machines, these are: reciprocating, rotary, screw, centrifugal and scroll. The first step in making a decision is educating yourself on the different types of air compressors that are available. Though they won’t be as powerful as larger units, portable compressors can be ideal for smaller construction projects. The refrigerant entering the compressor must be in the gaseous state, as liquids are notoriously incompressible. The compressor is then used to compress the refrigerant to a pressure that’s higher than in the evaporator (up to 8-10 times!) Below are a couple of types of air compressors that are energy-efficient.
