CO2Heat pump Technology introduction
  CO2 air cooled heat pump as a, air cooling of hot and cold water unit can meet the domestic, commercial and other various occasions about heating and cooling requirements. Compared with the conventional freon heat pump, has the following advantages：
  CO2 heat pump to prepare in the high temperature of 90 ℃ hot water, and the conventional freon heat pump hot water temperature can reach 55-65 ℃, and at the same time, the heating coefficient of performance of the CO2 heat pump is higher than freon heat pump cycle, to more than 4.0. 
    Can run efficiently under low temperature outside. Outdoor temperature for 5 ℃ when the cop still can reach more than 2.3. Outdoor temperature was minus 30. C can run normally, extremely suitable for northern area.
  Compared with the traditional advantages of ground source heat pump technology, no drilling, save a space.


 Natural working substance, more environmental protection, compared with other refrigerants unit refrigerating capacity is higher, higher operating efficiency.
   Not good security and chemical stability, high temperature decomposition.
   With good thermodynamic properties, high thermal conductivity.
   Volumetric refrigerating capacity is high, the device can significantly reduce the size, save materials;

Production of CO2 heat pump producted by our factory has the following characteristics ： 









 Compressor with built-in pump oil lubrication, trouble-free operation time is more than 20000 hours;
   Effectively solve the air conditioning heat and cold source of resource and environmental pressure is easy to obtain the high temperature of 90 ℃ hot water.
 System adopts advanced technology of electronic expansion valve, the refrigerating capacity of the corresponding temperature automatic control unit . 



 Winter summer conditions can automatically switch mode. 
   Outdoor parts for high pressure cooling device, can be installed outside the room, outdoor fan noise small, power is low.



 In the compressor system and the processing of all pipe insulation, minimize heat loss.
   Improve system can effect comparing unit in regenerative device.
   Heating condition, the single stage compressor to adapt to the environment temperature - 20 ℃, two-stage compressor to adapt to the environment temperature, 45 ℃
