Principles of refrigeration systems and requirements for related components

The principles of refrigeration systems are mainly achieved through four main components: compressor, condenser, expansion valve, and evaporator. The compressor sucks in and compresses the low-temperature and low-pressure refrigerant vapor generated by the evaporator, increasing its pressure and temperature. Then, the high-pressure refrigerant vapor enters the condenser, where it exchanges heat with a cooling medium (such as air or water) and condenses into high-pressure liquid refrigerant. Subsequently, the liquid refrigerant passes through the expansion valve to reduce pressure and temperature, entering the evaporator. In the evaporator, the refrigerant absorbs heat from the object to be cooled, evaporating into low-temperature and low-pressure vapor, which is once again sucked into the compressor, completing a refrigeration cycle.

Requirements for related components:

Compressor: The compressor is the core component of the refrigeration system, requiring high efficiency, stability, low noise, and low energy consumption. At the same time, the compressor needs to possess good thermal and mechanical performance to cope with long-term high-load operation.

Condenser: The condenser requires good heat dissipation performance to quickly condense the refrigerant vapor into a liquid state. Additionally, the condenser’s structure should be designed reasonably to minimize pressure loss and heat loss during the condensation process.

Expansion valve: The expansion valve is a throttling and pressure-reducing component in the refrigeration system, requiring precise control of refrigerant flow and pressure. Its design should ensure that the refrigerant fully absorbs heat during the pressure reduction process to achieve efficient cooling.

Evaporator: The evaporator needs to have high heat transfer efficiency to quickly absorb heat from the object to be cooled. At the same time, the evaporator’s structure should be easy to clean and maintain to ensure long-term stable operation of the system.

In addition, the refrigeration system also needs to be equipped with other auxiliary components, such as filters and dryers, to ensure the quality of the refrigerant and the normal operation of the system. Simultaneously, the design and installation of the refrigeration system need to follow relevant standards and specifications to ensure the safety and reliability of the system.

In summary, the refrigeration system achieves the refrigeration cycle through the coordinated action of components such as the compressor, condenser, expansion valve, and evaporator. The requirements for related components mainly focus on high efficiency, stability, low energy consumption, and ease of maintenance.
