[0002] The refrigeration cycle system operates by utilizing the phase change of a refrigerant at different pressures, achieving refrigeration through processes such as evaporation, compression, condensation, and expansion. The refrigerant absorbs heat and evaporates in the evaporator, is then compressed into a high-pressure gas by the compressor, releases heat and condenses into a liquid in the condenser, and finally, passes through an expansion valve to reduce the pressure before re-entering the evaporator to absorb heat, completing the cycle. The refrigeration cycle is then dried and filtered through a filter cartridge.
