21 -The refrigeration principle of the central air-conditioning system is liquid vapor refrigeration, which achieves refrigeration by removing part of the vapor. The high-temperature gas increases the temperature of the water, condenses into liquid, and then evaporates into low-temperature gas, continuously circulating to achieve refrigeration. The heating principle is that the compressor inhales low-pressure gas and compresses it into high-temperature gas, increases the water temperature through the heat exchanger, and then condenses it into a liquid. The liquid enters the evaporator and evaporates into low-temperature gas, which is continuously circulated to deliver hot water to the room that needs heating to achieve heating.
