Refrigeration and dehumidification equipment and air conditioner

Abstract

This utility model relates to a refrigeration and dehumidification device and an air conditioner. The refrigeration and dehumidification device includes an outer casing, an inner casing, a compressor, a condenser, a liquid receiver, an expansion valve, and an evaporator. The compressor draws in a low-temperature, low-pressure gaseous refrigerant and compresses it into a high-temperature, high-pressure gaseous refrigerant. The condenser receives the high-temperature, high-pressure gaseous refrigerant and condenses it into a high-pressure liquid refrigerant. The high-pressure liquid refrigerant is stored in the liquid receiver and then output to the expansion valve for throttling and pressure reduction, turning the refrigerant into a gaseous-liquid mixture. This mixture is then fed to the evaporator, where it exchanges heat with the outside through its outer wall, evaporating the gaseous-liquid mixture and returning it as gaseous refrigerant to the compressor. By absorbing heat from the outside through heat exchange, the evaporator lowers the temperature around it, achieving a cooling effect.
