Low Environmental temperature Air Source Heat Pump Heating System
Difference of normal ASHP and low environmental temperature ASHP
1. working conditions
Normal ASHP work when environmental temperature is above -10C, in lower temeprature, normal ASHP has problem in defrosting,and compressor
Low temperature ASHP could work well even temperature is low to -25C
2.Technology
Low temperature ASHP could defrost very fast , 90 seconds;
Low temperature ASHP has Jet booster compressor,compressor take use of refrigerant more efficiently
heating is stable in low temperature environment.
