Refrigerators are made up of four elements: compressor, condenser, pressure regulator and evaporator. In the refrigerator circuit, the compressors compress the refrigerant gas, providing the necessary mechanical energy to create the cold. Continue reading! We will explain everything about refrigerating compressors, from what is a refrigerator compressor, types of refrigeration compressors, prices and compressors in cold rooms .
What is a refrigerator compressor?
The compressor is the main part of the refrigerator, we could consider it the heart of the refrigerator. Refrigerating compressors mechanically force the fluid to circulate in a circuit, creating high and low pressure zones, thus ensuring that the fluid absorbs heat in one place and dissipates it. The compressor is driven by an electric motor and low-power equipment, it could be said that thanks to their exclusivity they are hermetic motor-compressors driven by other single-phase motors. The refrigeration process requires a closed circuit, thus preventing the refrigerant from expanding into the open air. When the refrigerant goes to the evaporator it is fed from a tank, the pressure it exerts will be as strong as that of the evaporator. Thus, the circulation of the refrigerant will cease and the temperature will rise until it reaches room temperature.
Types of refrigeration compressors
Now that we understand the general concept of refrigeration compressors, we must explain that there are different types of refrigerator compressors that are currently on the market, they are the most suitable for use in installations refrigerators. The types of compressors can be driven by any known motor, mainly electric or internal combustion motors. Now, the types of refrigeration compressors are the following:
Aerodynamic compressors: do not contaminate the refrigerant with air. The flow it displaces is variable depending on the pressure.
Rotary compressors: when the movement of the machines is rotary and continuous. They are directly coupled to the engine and do not have an intake valve, thus circulating the gas in the same direction.
Reciprocating compressors: they are specially composed of a cylinder, it has suction valves and discharge valves, where the piston is made. Reciprocating compressors are divided by classification: hermetic, semi-hermetic, and open.
Screw compressors: compressors can be gear or screw. The screw ones have two propeller-shaped rotors, one being the main one and one auxiliary. Both rotate in the opposite direction, the gas is trapped thanks to the movement carried out, which is transported from one end of the gear to the other.
Centrifugal compressors: they are capable of displacing large volumes of refrigerant gas, with low compression ratios, which is achieved by the acceleration of the gas in the rotor and thus increase the peripheral speed by increasing the compression value.< /li>

Cold chamber compressors
Before explaining about cold room compressors, we must understand what a cold room is. Although, it is a large refrigerator space in which perishable foods can be stored, as well as meat, fish or fruit, with the aim of keeping them for a long time. However, its operation requires a cooling process. First, the compressor is responsible for absorbing the liquid refrigerant and retains it until it enters the condenser. The refrigerant then transfers the heat of condensation and transforms into a liquid state. The compressor in the cold room forms a fundamental piece for the refrigeration system, thanks to its function of moving the refrigerant liquid. The motor makes it possible to start the entire circuit, but it is also made up of the condenser and evaporator. The most used compressors for cold rooms in the industrial sector are reciprocating compressors and rotary screw compressors. The first maintains important characteristics and functions thanks to its pressure, which can be half that of a screw compressor. Devices with less power require more frequent maintenance than those with higher power. However, the qualities of reciprocating compressors are still the most widely used in the industry for commercial refrigeration systems.
