C02 Heat Pumps

CO2 heat pumps; protecting the environment whilst producing unprecedented hot water temperatures

The development of CO2 heat pumps have created a high temperature (up to 110°C) water solution that was previously not available to HFC and HFO refrigerant heat pumps running traditional sub critical vapour compression cycles.

 

Cooltherm has exceptional experience in the application and maintenance of large scale ‘air to water’ and ‘water to water’ heat pumps operating using traditional refrigerants, these award winning heat pumps offer phenomenal levels of energy efficiency when producing water temperatures at the sub circa 50°C mark for low temperature heating applications. However, producing the high-water temperatures needed to allow the industry to move away from conventional direct hot water boilers was more challenging for traditional heat pump technology. Cooltherm has now added CO2 refrigerant heat pumps to our product portfolio to allow our clients to produce green efficient hot water up to 110°C further decarbonising their sites.

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.

Cooltherm can provide bespoke and standard high temperature CO2 heat pump solutions with a range spanning from 50kW to 1.4+mW.
