Screw Air Source Heat Pump
This series of screw air source heat pump is for cooling and heating with fan coil unit or air handling unit. If you have any preference of the compressor brand, please inform. If there is any different requirement other than the standard product, please inform, will have customization upon request.
| Unique design, less investmentModular design suitable for bigger application area, automatic energy output adjustment as per actual load requirement.Multi parallel connection, multi steps start by sequence, minimize starting current, safe to electricity grid. |  |
| Fully-automatic controlThe operation and management of this unit are controlled by microcomputer system. It is easy to operate. The units turn on/off the compressor automatically according to the load, making the units operate on the point of the most economical and energy saving. And there are complete protective functions such as error self-protection system and anti-freezing automatically in winter. |   |
Intelligent defrosting
Each circuit is separate to the others in refrigerant system, and each system operation is controlled independently. The parameters can be set for automatic defrosting according to the different climatic conditions (temperature and humidity), defrost is thorough and energy-saving, increasing the heating efficiency. And the defrosting has no significant influence to the indoor air-conditioning temperature.
Intelligent anti-freezing
This unit adopts anti-freezing automatic dual-class protection, preventing the water system being damaged once the refrigerant freezing at winter. The anti-freezing protection can be quitted automatically when the water temperature is increased according to the operation of heating or pump.
Convenient operation
Each unit is strictly tested. All the protective parameters is set. It is ready for application right after the power supply and water pipe is connected.
1. Heat recovery for domestic hot water
2. Water flow switch
3. PLC controller
4. R407C refrigerant
5. For any other feature, please contact us for customization
