The air-conditioning refrigeration system generally comprises a compressor, a condenser and an evaporator, wherein high-temperature refrigerant output by the compressor firstly enters the condenser, exchanges heat with the outside through the condenser to form low-temperature refrigerant (generally at the temperature of 40-50 ℃), enters the evaporator, absorbs external heat through the evaporator and then returns to the compressor, and therefore circulation is completed. Because the evaporator absorbs external heat in the working process, condensed water is formed on the surface of the evaporator, and a water receiving disc is arranged below the evaporator and used for receiving the falling condensed water. The temperature of the condensed water is lower, the surface temperature of a common evaporator is 7-12 ℃, the temperature of the condensed water is about 10-15 ℃, and therefore the condensed water has certain cold energy. In the humid working occasion of air, the air conditioner generates more condensed water during operation, but the refrigeration system of the air conditioner in the prior art does not fully utilize the cold energy of the condensed water.

The heat exchange tube is characterized by further comprising a heat exchange tube 5, a first three-way electromagnetic valve 6, a second three-way electromagnetic valve 7 and a controller 8. The heat exchange tube 5 is a copper coil, the heat exchange tube 5 is embedded at the bottom in the water receiving tray 4, the outlet of the condenser 2 is connected with one end valve port of the first three-way electromagnetic valve 6 through a pipeline, the other valve port of the first three-way electromagnetic valve 6 is connected with one end of the heat exchange tube 5 through a pipeline, the other end of the heat exchange tube 5 is connected with one valve port of the second three-way electromagnetic valve 7 through a pipeline, and the other valve port of the second three-way electromagnetic valve 7 is connected with the inlet of the evaporator through a pipeline. And the third valve port of the first three-way electromagnetic valve 6 and the third valve port of the second three-way electromagnetic valve 7 are connected through a pipeline.
The controller 8 adopts a single chip microcomputer, and the signal output end of the controller 8 is respectively connected with the control ends of the first three-way electromagnetic valve 6 and the second three-way electromagnetic valve 7. Therefore, the controller 8 can control the first three-way electromagnetic valve 6 and the second three-way electromagnetic valve 7 to work, so that the refrigerant flowing out of the condenser 2 enters the evaporator 3 after passing through the heat exchange tube 5, and exchanges heat with the condensed water inside the water pan 4 through the heat exchange tube 5, and the cold energy of the condensed water is utilized. Or the refrigerant flowing out of the condenser 2 is directly introduced into the evaporator 3, which is a normal flow path of the refrigerant of the conventional air conditioning system.
