CO2 R744 Heat Pump System High Temperature Cold Climate

Principle Introduction
The compressor sucks low-temperature and low-pressure gaseous carbon dioxide refrigerant from the evaporator, and compresses the carbon dioxide refrigerant into a high-temperature and high-pressure supercritical fluid through work. The high-temperature and high-pressure supercritical fluid enters the gas cooler to exchange heat with water, and is cooled in the gas cooler. The high-pressure fluid releases a lot of heat, and the water absorbs the heat released and the temperature continues to rise. After the high-pressure fluid is throttled and depressurized by the expansion valve, it absorbs the heat in the surrounding air and evaporates into low-pressure gas through the action of the fan in the evaporator, and is sucked into the compressor to be compressed, so that it circulates repeatedly to provide hot water.

Features
Natural environmental protection refrigerant: CO2 refrigerant, ODP is 0, GWP is 1, no pollution to the environment, non-toxic, non-flammable;
High water outlet temperature: the supply/return water temperature can reach 65°C/45°C, and the highest outlet water temperature can reach above 75°C, suitable for radiators;
Excellent low-temperature performance: at -35°C ambient temperature, heating is still normal;
High efficiency: the heating performance COP can reach 1.8 at an ambient temperature of -30ºC;
Wide range of application: it can work normally in the ambient temperature range of -35ºC~20ºC, suitable for cold areas
We can provide bespoke and standard high temperature CO2 heat pump solutions with a range spanning from 6kW to 160kw
