CO2 Heat Pumps //
Clear about difference between CO2 heat pump and atmospheric CO2?
It is easy for confusion to arise, after all how can a CO2 heat pump help reduce CO2 emissions?
Combustion appliances like boilers and fossil fuel engines continuously produce CO2 as a by product of their operation, this CO2 is released into the atmosphere via the flue or exhaust.
By contrast CO2 heat pumps use Carbon Dioxide as the working fluid, the CO2 is contained permanently within the appliance. It is the thermodynamic properties of the expansion and compression of CO2 that enables a heat pump to work.
The CO2 that Clade use is captured as a by-product of other industrial processes. Unlike other natural refrigerants such as; propane which is component of natural gas, or ammonia which is made in a high carbon process.
Other types of heat pump use different working fluids, typically HFCs or HFOs which contribute more to global warming. This contribution is measured using GWP “global warming potential”, CO2 has the lowest possible score of 1.
Using CO2 heat pumps will result in an improvement in carbon reduction both directly in the heat output and indirectly through the production, service and disposal of the working fluid.
Other advantages of CO2 heat pumps include higher operating temperatures which more closely match existing heating systems and enable greater value in heat recovery. This can reduce the cost of the installation and operation of your facility.
CO2 is non toxic and inert which makes the burden of managing the risks lower than other working fluids.
