Zew Zealand 8kw Residential CO2 Heat Pump System for Combined Space
Heating and Hot Water Heating
Description of DORIN INVERTER CO2(R744) Heat Pump Systems Carbon
dioxide high temperature heat pump air source and water source
The carbon dioxide transcritical heat pump unit has a significant
energy saving effect in waste heat recovery. Through the excellent
characteristics of carbon dioxide supercritical, only a small
amount of electricity is required to produce high-temperature hot
water. In the cold area of 100 to 20 degrees in the north, the
waste heat of the air can be absorbed. In the supercritical area of
carbon dioxide, the gas heat exchanger can still efficiently
produce high-temperature hot water above 60 °C.
CO2 Heat Pump Working Principle
The working principle of CO2Heat Pump is that the refrigerant
absorbs the heat in the air(or water), compressed by the compressor
to become a high-temperature and high-pressure gas to be
discharged. The high-temperature and high-pressure refrigerant gas
is cooled by the gas cooler and transfers the heat to the water
then realize the heating function.

Performance of Zew Zealand 8kw Residential CO2 Heat Pump System for
Combined Space Heating and Hot Water Heating
Ultra-low temperature working conditions: ambient temperature
DB-10-C, water inlet temperature 9°C;
Defrost condition: ambient temperature DB2°C/WB1°C, water inlet
temperature 9°C; low temperature condition: ambient temperature
DB7°C/WB6°C, water inlet temperature 9°C; standard working
condition: ambient temperature DB20°C /WB15°C, inlet water
temperature 15°C; high temperature working condition: ambient
temperature DB38°C/WB23°C, inlet water temperature 29°C.
Installation Notes:
1. The spacing around the installation must not be less than Im;
2. The pipelines other than the heat pump should be protected from
frost and heating elements can be installed;
3. Heat insulation and protection measures should be taken for the
pipelines for hot water circulation to prevent heat loss.
