The French fries freezer uses the same principle as the air conditioner. The freezer uses a compressor to compress gaseous freon into high temperature and high pressure gaseous freon, and then sends it to the condenser to dissipate heat and become liquid freon at room temperature and high pressure. . Then it goes to the capillary and enters the evaporator. After the freon reaches the evaporator from the capillary, the space suddenly increases and the pressure decreases. The liquid freon will vaporize and become gaseous low-temperature freon, which absorbs a lot of heat, and the evaporator will change. Cold, using refrigeration or air-cooling to achieve cooling in the room (box).
