What is the cycle principle of Hot Or Cold Water Cycling Machine?

The circulation principle of Hot Or Cold Water Cycling Machine: The liquid refrigerant in the Hot Or Cold Water Cycling Machine absorbs the heat in the water and begins to evaporate. Finally, a certain temperature difference is formed between the refrigerant and the water, and the liquid refrigerant is completely evaporated. 

After the gaseous state is sucked and compressed by the compressor (pressure and temperature increase), the gaseous refrigerant absorbs heat through the condenser (air-cooled/water-cooled), condenses into a liquid, and is cooled by a thermal expansion valve (or capillary) to become a low-temperature low-pressure refrigeration. The agent enters the evaporator and completes the refrigerant cycle.
