Description of AC Inverter CO2 Heat Pump Residential CO2 heat pump system for combined space heating and hot water heating

Energy-efficient and renewable residential CO2 heat pump

About the technology
An air to water heat pump is a very efficient device that uses heat in the ambient air for hot water production. Its heat energy output is about three to five times as high as the electricity input. The way it works is opposite to that of an air conditioning system: it uses a refrigerant cycle with a compressor and heat exchangers to extract heat from the ambient air and transfers this heat to water.

Air to water heat pump uses the natural refrigerant CO2, which has a Global Warming Potential (GWP) of only 1. Typically heat pumps use a synthetic refrigerant gas such as R410A, which has a GWP of 2088. This number indicates that, when emitted into the air, its impact is 2088 times higher than CO2.

A CO2 Air to water heat pump is a good fit for:

High temperature domestic hot water production
High temperature radiator heating in existing, moderately insulated homes.
Note: This application requires excellent control of heating system water flow and temperatures. Customer satisfaction is our top priority


CO2 Heat Pumps for both retrofit and new build applications
Heat Pumps are a source of renewable hot water generation at your site, whether residential or commercial:

1) The Renewable Heat Incentive (NDRHI) could give greater returns with respect to retrofit applications.
2) Hot water production within a 5-week period is preferable to seasonal heating only. This setup greatly reduces both cost and carbon emissions.

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.
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 -30℃;
Wide range of application: -35℃~20℃, suitable for cold areas.

Heat pumps have been developed in large numbers especially for hot water generation, for example in the housing industry, in commercial applications and in industrial applications. Thanks to the unique core technology, units also ensure extremely reliable operation and high heat outputs even at low outdoor temperatures.

The heat pump system generates flow temperatures of 90 °C at outdoor temperatures as low as -25 °C and with a hot water COP of up to 3.88. The latest inverter scroll compressors provide the decisive advantage in this regard, ensuring a considerable boost in efficiency that is beyond the capabilities of fixed-speed systems.
