Description
Air source heat pump manufacturer: FUJIREJA
Air source heat pump R32 Specification
Working in ultra-low temperature with strong heating.
DC Inverter Heat Pump adopts the latest generation of high-efficiency compressors with enhanced vapor injection (EVI) technology. The compressor greatly enhances normal heating performance in winter under ultra-low ambient temperature lower than -35°C. And it has a cooling function in summer as an air comfortable air conditioner.
Split design, higher anti-frozen performance
Split design with the outdoor and indoor unit, the condenser (heat exchanger) and circulation water pump is installed inside the indoor unit, refrigerant is connected by copper pipe between outdoor unit and indoor unit, this design greatly improves anti-frozen performance, no any special treatment is required when the indoor unit is installed in the room where it’s around temperature higher than 0°C. No, any more worry about the possibility of freezing damage on the products.
Dc Inverter Technology with wider operation range, higher efficiency, and lower noise
-DC inverter technology makes the system start with small currency and impacts to power grid very slightly. -Automatically adjustment of the compressor running speed according to different ambient temperature, give great helps to keep the temperature more stable and comfortable, especially in ultra-low ambient temperature conditions.
-Variable speed control: The system will be running at a low frequency when it reaches preset room temperature, which makes the relative energy saving up to 30%, at the same time, lower frequency mode can reduce noise greatly.
Incorporated with multiple terminals, and easier for renovating an older house
Our heat pump not only can be incorporated with the city central heating network radiator but also be connected to the fan coil for heating and cooling, as well as the water floor heating.
Cellphone Control, Easy Operation
Intelligent control system
GPRS wireless transmission modules rely on mature GPRS/GSM networks, and it is not necessary to connect to another wireless network, In the area covered by all mobile signals, data communication can be quickly established to obtain the real-time operating status of the unit and deliver data remotely.
