Specifications

1.Energy recovery airflow is 480/320/160m3/h
2.Three speed EC motor fan
3.Fresh air filter class is G4+F7+H10
4.220-240V

 Energy saving principle

 

Working principle of    Double way by-pass class G4+F7+H10 exhaust air heat pump 

 

It can expel the stale air indoor out of room, meanwhile supplying the fresh air outside into the room, by using the advanced heat/energy recovering technology, the energy can exchange taking advantage of the difference of the temperature and humidity between indoor and outdoor air. By this means, it can not only smooth away the problem of indoor pollution, but also saving energy.

 

The main features  : 

1. Heating capacity of heat pump system 2480 W

2. Cooling capacity of heat pump system 2350 W

3. Power supply 220-240/1/50 V/Ph/Hz

4. External static pressure 130Pa

5. Three speed EC motor fan

6. Auto defrosting and bypass central controller

7. The airflow is controlled according to the ambient temperature.
