The pure electric evaporation module makes use of the heat pump principle in the air-conditioning and refrigeration industry. After the high-temperature and high-pressure gaseous freon is discharged from the exhaust port of the compressor, it enters the heater. It releases heat to the liquid material in the heater, causing the liquid material to evaporate, and the freon itself condenses and turns into a high-temperature and high-pressure liquid state. The high-temperature and high-pressure liquid freon then passes through the expansion valve for throttling and pressure reduction, becoming a low-temperature and low-pressure mixture, and then enters the condenser to conduct heat exchange with the secondary steam of the liquid material. After absorbing heat, the mixed freon completely transforms into a low-temperature and low-pressure gaseous state. The secondary steam of the liquid material releases heat and condenses into a liquid solvent, which is recovered. The low-temperature and low-pressure gaseous freon then enters the compressor again and is compressed into a high-temperature and high-pressure gaseous state. In the entire closed process, the freon in the cylinder and the liquid material achieve a full mutual utilization of heat and cold through heat transfer in the titanium components. The whole process only requires providing the energy needed for the compressor to compress the freon gas.
