Air Source Heat Pump Underfloor Heating Introduction
- Air source heat pump The cold (hot) water unit adopts modular
design. It does not need to set up a standby unit. During the
operation, the computer automatically controls and adjusts the
running status of the unit to make the output power adapt to the
working environment.
- The performance of air source heat pumps will vary with outdoor
climate changes.
- In places where the outdoor air temperature in the north of China
is low, an auxiliary heater is required due to insufficient heat
supply in the winter of the heat pump.
Air Source Heat Pump Underfloor Heating Features
It adopts Copeland compressor and operates in an ultra-wide range.
◆The reverse flow circuit is arranged to ensure the subcooling
degree of the refrigerant, which effectively improves the heating
efficiency and the normal operation of the unit at low temperature.
◆ It operates under ultra-low temperature conditions and can work
normally at -25 °C.
◆ Energy efficiency guarantee, solve the common problem of low
temperature, no heat, low energy efficiency.
