kompressorkjøling

Kompressorkjøling, also known as vapor-compression refrigeration, is the most common type of refrigeration system used today. It operates by circulating a refrigerant through a closed loop, where it undergoes phase changes to absorb heat from a cooled space and release it elsewhere. The cycle begins with the compressor, which increases the pressure and temperature of the gaseous refrigerant. This hot, high-pressure gas then flows to the condenser, typically located outside the cooled space, where it releases heat to the surroundings and condenses into a high-pressure liquid.

The liquid refrigerant then passes through an expansion valve, which drastically reduces its pressure and temperature, causing some of it to vaporize. This cold, low-pressure mixture of liquid and vapor then enters the evaporator, which is located inside the cooled space. Here, the refrigerant absorbs heat from the surrounding air or medium, causing the remaining liquid to evaporate into a low-pressure gas. This cooled gas then returns to the compressor, and the cycle repeats. The efficiency of a kompressorkjøling system depends on factors like the type of refrigerant used, the operating temperatures, and the design of the components.
