An example today is an energy efficient and renewable residential CO2
An air source 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.
CO2 air source heat pumps are ideal for:
High temperature domestic hot water production
Space heating in well-insulated houses (near-zero energy houses or
Leomon Technology introduces CO2 refrigerant into its air source heat
pump. The product's improved energy efficiency means less household electricity
Leomon Technology's CO2 air source heat pumps set new standards for
compactness, light weight and low noise. Leomon CO2 heat pumps are now
available in homes, providing efficient, environmentally friendly heating and
Typically, heat pumps use a synthetic refrigerant gas such as R410A,
which has a Global Warming Potential (GWP) of 1725.
Leomon Technology develops CO2 heat pump
Leomon Technology's air system uses a CO2 (R744) heat pump and uses
ventilation air to deliver heat, reducing heating costs and emissions.
Leomon Technology, a leading heat pump manufacturer, is paving the way
for this greener future, introducing a new air-to-air heat distribution system
for homes that uses its ventilation system to deliver heat around the house
without the need for traditional, less efficient water-based systems.
In today's well-isolated new homes, a controlled ventilation system is
required to ensure hygienic air exchange from outside to inside. The air system
takes advantage of this ventilation system, which serves the dual purpose of
distributing outside air throughout the building as well as carrying the heat
emitted by the Leomon Technology heat pump. Using air as a heat carrier
eliminates the need for a water-based heat distribution system, as the amount
of air circulating the house is sufficient to provide sufficient heat for the
Leomon Technology CO2 Heat Pump
Integral to the system is a CO2 heat pump from Leomon Technology, which
uses 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. Leomon Technology's
Air Source Heat Pump is the first of its kind to use the natural refrigerant
carbon dioxide and has a GWP of only one.
A heat pump is so efficient that it produces approximately three to five
times as much thermal energy as its 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.
The cost saving element of the Air to Air System during construction is
a major selling point for the industry. What customers say: "We give
builders the opportunity to completely abandon the water-based distribution
system of conventional heating systems. Eliminating this system can save
thousands of euros in the planning and construction of new homes.
