Presents main reasons of the compressor damaged in winter by analyzing an accident of the windcooling heat - pump unit. Gives some Suggestions for the user and the producer.
Faults: due to the drive air flows to the windcooling, cooling effect is not obvious, especially the air temperature is higher, and in the summer, can only be strong seasonal use.
