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.

Project Overview:
The project is located in No 40, Inner Mongolia,the lowest temperature is -25C for one week, average temperature -19C in winter.
The heating project is 5000 square meter of Medical ambulance'd buiding.
Project was put into use in 2017, during the entire heating season, system is stable and reliable high-efficiency operation.
Compared to the average coal burned by the users before, the new system has significant results in savings of raw coal , reduce SO2 , CO2 ,ash and slag emissions .
