Why does a refrigerator need a compressor? The compressor ensures the pumping of the refrigerant through the heat exchange system, i.e. it is responsible for the quality of the cooling. Toronto appliance repair experts offer to take a closer look at compressor types existing today and their features.
The design features of the compressors make it possible to divide them into three categories:
This type of device is in many ways similar to the one-cylinder internal combustion engine. An identical crankshaft driven by an electric motor is inside it. Compressors of this type can be produced in various versions:
Pros:
Cons:
The operation of rotary compressors is based on the compression of the refrigerant and its movement through the pipes due to the rotation of the working bodies (plates, screws, Industrial Washer repair, spirals).
Pros:
Cons:
Linear compressors are based on reciprocating piston movements. Thanks to their design, it is possible to significantly reduce the noise level of the compressor and reduce energy consumption by up to 45%.
Pros:
Cons:
Inverter compressor control technologies are beginning to be adopted by most manufacturers. This technology allows to quickly cool the air in the refrigeration compartment to the required level. When it is achieved the compressor will reduce the speed to a minimum but not turn off. This minimum will maintain the temperature at the same level.
In the case of traditional compressors, when the temperature drops, they work at maximum and turn off when the required temperature is obtained. Due to such shutdowns and starts, temperature fluctuations occur, and this negatively affects the shelf life of products. Also, inverter technology made it possible to reduce the energy consumption of the refrigerator, reduce the noise level and increase the life of the compressor.
