Product Details

Anti-Freezing Air Source Heat Pump Low Temperature Type Automatic Desfroting

Brief Introduction

The compressor is equipped with a low temperature antifreeze electric heating belt, which is beneficial to the low temperature start of the compressor;

Continuous heating is better than air conditioning in low temperature environments
When the air conditioner is below 0 °C, the heating effect is greatly reduced, resulting in "the colder the air conditioner can not be used normally in some areas." The ultra-low temperature air source heat pump hot air enthalpy can continuously and stably heat at -25 ° C low temperature environment, and the application range is wider, and the use process is more worry-free.

Intelligent defrost
Advanced defrosting control mode ensures frost defrosting and no frost removal. Defrost conditions:
1) coil temperature <-7 ° C;
2) Defrost interval > 45min;
3) 20% heat reduction (adjustable)
