[0039] Combine below Figure 1 ~ Figure 4 The technical solution provided by the present invention is described in more detail.
[0040] An embodiment of the present invention provides an air conditioner, which may specifically be a heat pump unit. The air conditioner includes a first heat exchanger 1, a second heat exchanger 2 and a spray head 9, and the spray head 9 is in fluid communication with the first heat exchanger 1. When the air conditioner is in the heating mode, the spray head 9 can spray the water in the first heat exchanger 1 onto the second heat exchanger 2 for defrosting. A pipe 3 is provided between the nozzle 9 and the first heat exchanger 1, and a drain valve 6 is provided at the lowest part of the pipe 3.
[0041] In this embodiment, taking the air conditioner as a household air conditioner as an example, the first heat exchanger 1 is specifically an indoor heat exchanger, and the second heat exchanger 2 is specifically an outdoor heat exchanger.
