FIG. 2: the utility model discloses outdoor evaporator defrosting device's installation schematic diagram.
Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.
As shown in fig. 1 and 2, the defrosting device of the outdoor evaporator of the present invention comprises an outdoor evaporator, a defrosting water coil 1, a defrosting water tank 2, a defrosting plate exchanger 3 and a defrosting circulating water pump 4; wherein, the defrosting water coil 1 is arranged on the outdoor evaporator, the defrosting water tank 2 is connected between the defrosting water coil 1 and the defrosting plate exchanger 3, and the defrosting circulating water pump 4 is connected between the defrosting water coil 1 and the defrosting plate exchanger 3.
