A kind of air conditioner outdoor machine defrosting method, air-conditioner outdoor unit include：Outdoor machine shell, wind turbine, heater and heat exchanger,
During operation of air conditioner, when outdoor temperature is less than set temperature, infrared heater is opened, the wind of the blowout of wind turbine is by heater
Heat exchanger is passed to, the frost layer on heat exchanger is melted.
Outdoor machine of air-conditioner is divided into wind turbine chamber and compressor chamber by outdoor machine of air-conditioner of the present invention, and wind turbine chamber is divided into air inlet
Two cavitys of chamber and air-out chamber, while two cavitys arrange that fan blade is arranged in air-inlet cavity above and below, this structure design can be with
Realize outer machine upper air inlet, side air inlet and lower outlet air, side air-out；
Heater and heat exchanger are arranged in air-out chamber, and heater is between fan blade and heat exchanger；
Heater and heat exchanger are to lie in a horizontal plane in cavity, and when outer machine heat exchanger is defrosted, heater is opened
It opens, the heat transfer generated using upper air inlet makes the heat of hot fluid be absorbed by heat exchanger to heat exchanger, to exchange heat
Frost layer on device is melted, and during defrost systems stay to indoor heating；
Same level in cavity both sides designs the running track of having heaters, during defrost, along running track
Horizontal reciprocating movement is carried out, to increase the heating surface area of heat exchanger；
The wind turbines such as axis stream, centrifugation may be used in wind turbine, and concrete form is unrestricted；
Air-out chamber bottom is equipped with drainage channel, the defrosting water generated when for excluding defrost.
The present invention carries out heating defrosting by being changed to air conditioner outdoor unit structure, with heater heat exchanging device, simultaneously
During defrost, compressor is not shut down, and system carries out interior to continue heat supply, and indoor comfort is made not influenced by defrost,
To the temperature and comfort of indoor environment during ensureing defrost.
