Ultra Low Temperature Heating and Cooling Heat Pump Air Source for Office Building
Brief Introduction
1. The effect of low temperature heating is not attenuated
The ultra-low temperature frequency conversion air-enhanced
compressor is used to achieve stable operation at -25 °C, and the
heating stability at -20 °C is not attenuated.
2. Continuous heating is better than air conditioning in low
temperature environment
When the air conditioner is below 0 °C, the heating effect is
greatly reduced, which leads to the fact that some areas are “cold
and cold, and the air conditioner cannot be used normally”. 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.
3. One machine is more economical than air conditioner
Refrigeration is the duty, heating is the ability, one machine to
solve the two needs of winter heating, summer cooling. Compared
with the use of air conditioning or other refrigeration and heating
methods, it is convenient and can greatly reduce the user's use
cost.
4. Floor heating heating experience is more comfortable than air
conditioning
