[0024] Specifically, a solenoid valve is provided at the connection between the water collecting box 1 and the drainage pipe 101, and the solenoid valve is electrically connected to the PLC controller; the PLC controller controls the opening and closing of the solenoid valve by comparing the detection result of the temperature sensor 304 with a preset value.

[0025] Specifically, the condensed water assembly 2 includes a water outlet pipe 201 and a sponge 202; the top of the water outlet pipe 201 is connected to the drainage pipe 101, and a plurality of water outlet holes 203 are provided at the bottom of the tube body of the water outlet pipe 201. The sponge 202 is provided at the bottom of the water outlet pipe 201, and the sponge 202 is located directly above the condensation section of the heat pipe 303 in the heat exchanger 3; the condensed water in the water collecting tank 1 flows into the water outlet pipe 201 through the drainage pipe 101, and the sponge 202 absorbs the condensed water flowing out of the water outlet holes 203, and the sponge 202 evenly drops the condensed water on the fins 308 at the condensation section of the heat pipe 303.

[0026] Specifically, the heat exchanger 3 includes a heat pipe 303, a temperature sensor 304, a water storage tank 305, a partition 306, a shell 307 and a fin 308; the partition 306 divides the interior of the shell 307 into the fresh air channel 301 and the exhaust air channel 302, a plurality of the heat pipes 303 are arranged on the partition 306, and the heat pipes 303 are connected by the fins 308, the evaporation section of the heat pipe 303 is located in the fresh air channel 301, the condensation section of the heat pipe 303 is located in the exhaust air channel, the temperature sensor 304 is arranged in the fresh air channel 301, and the water storage tank 305 is arranged in the exhaust air channel and directly below the heat pipe 303.

The water collecting tank 1 stores condensed water generated by the air conditioner indoor unit 100 during refrigeration. When the temperature sensor 304 detects that the temperature of the air outlet of the fresh air channel is lower than the preset value, the PLC controller controls the solenoid valve at the bottom of the water collecting tank 1 to close. At this time, the fresh air passes through the heat exchanger 3 and exchanges heat with the exhaust air before entering the room.
