Product Description

Principle Introduction
The compressor sucks low-temperature and low-pressure gas 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, in the evaporator, the fan absorbs the heat in the surrounding air and evaporates into a low-pressure gas, which is sucked into the compressor and compressed, so that it is repeatedly circulated to produce hot water.
Features
Natural environmental protection refrigerant: ODP is 0, GWP is 1, no pollution to the environment, non-toxic, non-flammable
Excellent high temperature heating performance: the highest water output can reach above 90ºC
Excellent low temperature performance: at -20°C ambient temperature, 90°C high temperature hot water can still be produced
High efficiency: the heating performance COP can reach 4.5, and when the hot water is produced at low temperature, the COP is still above 2.0
Wide range of application: it can work normally in the ambient temperature range of -20ºC~43ºC, suitable for the production of domestic or industrial hot water
Our CO2 heat-pumps operating a with transcritical vapour compression cycle can now provide hot water temperatures that match the typical direct hot water requirements for most buildings. The DHW requirements for most buildings are in fact quite small and can often be offset against the buildings base cooling loads further increasing the systems energy efficiencies.
We can provide bespoke and standard high temperature CO2 heat pump solutions with a range spanning from 6kW to 160kw
