How does water heating and air conditioning use well water to cool and heat?

refrigeration principle of water heating and air conditioning: in summer, low-temperature well water is rolled into the evaporator in the air conditioner through pipes, and indoor hot air is sucked into the evaporator by the fan in the air conditioner, and heat exchange occurs between them by using thermodynamic principle. The low-temperature well water absorbs the heat of hot air through the pipe wall and fins, and the temperature of the hot air from which the heat is absorbed is reduced, and it is blown into the room by a fan, and the temperature of the absorbed water is increased, and it flows back to the return well through the return pipe. In this way, the indoor hot air is continuously absorbed by water and the temperature drops, thus achieving the purpose of refrigeration. Heating principle of water heating air conditioner: it uses the waste heat of the stove when cooking at home to send the heated hot water into the evaporator in the air conditioner through the pipeline, and at the same time, the fan in the air conditioner sucks the indoor cold air into the evaporator by using the thermodynamic principle. Heat exchange occurs between them, and the heat carried by water is transferred to the fins through the pipe wall and fully absorbed by cold air. After absorbing heat, the temperature of cold air rises, and the temperature of water which is blown into the room by the fan and released heat decreases, and then flows back into the furnace for heating through the backwater pipeline. In this way, the indoor cold air continuously absorbs the heat released by water and the temperature rises, thus achieving the purpose of heating. The whole process is designed and manufactured with self-circulation function without any auxiliary power, which completely overcomes the disadvantage that other water air conditioners can only realize circulation by relying on pipeline pumps.
