CO2 Heat Pumps

CO2 Heat Pumps

CO2 heat pumps use carbon dioxide (R744) gas as an environmentally friendly refrigerant within the compression/expansion cycle. R744 (CO2) is becoming increasingly popular due to its excellent properties. With an Ozone Depleting Potential (ODP) of 0 and a Global Warming Potential (GWP) of 1. C02 heat pumps come in both ground source and air source versions. They are ideally suited to applications which require large amounts of hot water such as;  residential, commercial, schools, hotels, hospitals and industry. Climate Control offer a range of CO2 heat pumps with thermal output capacities of 11kW to 118kW.

Advantages

  • Water Heating up to 90 degrees
  • Natural Refrigerant
  • Small Footprint
  • Modular System for Increased Capacity
  • Silent Operation
  • Proven High Temperature Performance

Opportunities for Releasing the potential of CO2 Heat pumps

Dairy

Dairy Farms – CO2 heat pumps can be used to simultaneously cool milk and produce hot water up to 90C for wash down. This can dramatically reduce the running costs of a milking parlour and improve profitability.

Milk processing – CO2 heat pumps can simultaneously cool milk in one sector of the plant whilst proving heat for pasteurisation in another. This means removing all fuel on the pasteurisation process in favour of free, normally rejected heat from the refrigeration process.

Cheese Making – Similar to milk processing Co2 heat pumps can be used to provide heat from pasteurisation from the heat rejected from the refrigeration process.


Hot water

Due to its unique properties CO2 heat pumps can produce hot water up to 90C without a significant drop in performance. This allows us to produce hot water for many industries at a cost much lower than running on oil or LPG. Industries that can benefit

Hotels: Hotels have a very high hot water demand and many have no access to piped gas lines so energy costs are very high. A CO2 heat pump can reduce those costs significantly. Where a simultaneous cooling load exists like replacing a chiller the running costs are even lower than piped gas.

Camping sites & Adventure Centres: Another industry with high hot water demands and often limited access to fuels other than oil or LPG. Using a CO2 heat pump can significantly reduce your running costs

Process heating

Industries that require large volumes of hot water can benefit enormously from heat pumps. Where high temperature water is required CO2 heat pumps can produce hot water up to 90C and provide simultaneously cooling for other areas of production. Businesses that can benefit from the technology include:

  • Brewing
  • Distilling
  • Pharmaceutical
  • Breadmaking
  • Chocolate manufacturing
  • Meat processing
  • Pig farming
  • Poultry farming


District Heating: CO2 heat pumps are ideal for providing high temperature water throughout district heating systems within buildings or throughout entire street areas. 

Low temperature energy can be collected from Air, ground, water, sewage or waste heat from heat rejecting industries such as data centres. 

The high flow temperature means the water is warm enough to supply already existing systems without the need for significant retrofits.
