Description
An example today is an energy efficient and renewable residential CO2
heat pump
About technology
An air-to-water heat pump is a very efficient device that uses the heat
in the ambient air to produce hot water. Its thermal energy output is
approximately three to five times the electrical input. It works the opposite
of an air conditioning system: it uses a refrigerant cycle with a compressor
and heat exchanger to extract heat from the ambient air and transfer that heat
to the water.
Our air-to-water heat pumps use 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 figure shows that
when emitted into the air, the impact is 2,088 times greater than that of
carbon dioxide.
Carbon dioxide air to water heat pumps are ideal for:
1. High temperature domestic hot water production
2. High temperature radiator heating in existing moderately insulated houses.
About Product
The introduction of CO2 as a
refrigerant into its air-to-water heat pump improves energy efficiency and
means less household electricity is required.
CO2 air-to-water heat pumps set new standards for compact size, weight
and low noise CO2 heat pumps are now beginning to be used in homes across
Europe, providing efficient, environmentally friendly heating and hot water.
Typically, heat pumps use a synthetic refrigerant gas such as R410A,
which has a Global Warming Potential (GWP) of 1725.
Ventilation system
The air system uses a CO2 (R744) heat pump and uses ventilation air to
deliver heat, reducing heating costs and emissions.
Our CO2 Heat Pumps
Our CO2 heat pumps use a refrigerant cycle with a compressor and heat
exchanger to extract heat from the ambient air and transfer it to the water at
the start of the central heating process. Typically, heat pumps use a synthetic
refrigerant gas such as R410A, which has a Global Warming Potential (GWP) of
1725. Our air-to-water heat pump is the first of its kind to use the natural
refrigerant carbon dioxide and has a GWP of only one.
A CO2 heat pump is highly efficient, producing approximately three to
five times as much thermal energy as the electrical input. Given the new EU
building efficiency and HFC refrigerant phase-down targets, their role as a
space and water heater energy saving way will undoubtedly make them an
attractive alternative to traditional European refrigerant models.
Save costs
CO2 heat pumps can give builders the opportunity to completely forgo the
water-based distribution systems of traditional heating systems. Eliminating
the system could save thousands of euros in the planning and construction of
new homes.
