CO2 is termed a “Natural Refrigerant” because it exists in the natural environment. Release into the atmosphere from refrigeration systems has a negligible effect compared to other CO2 sources that are driving the global warming debate. As a refrigerant, it is a manufactured product that conforms to strict purity specifications. Its physical properties require special handling.
Independent tests are said to have proven the energy saving capabilities of Adande’s Aircell air flow management system.
Daikin says the “mildly flammable” refrigerant R32 will be used in its VRV air conditioning systems in the future.
Guidelines for the use of hydrocarbon refrigerants in static refrigeration and air conditioning systems
With the introduction of the revised EU Ozone Depleting Substances Regulation and the introduction of a Climate Change Policy by the UK Government, it is considered likely that more refrigeration system designers and users will be turning to alternative refrigerants such as hydrocarbons. The increased application of this technology will bring with it many technical and safety issues.
Space Engineering has launched a new CO2-based integrated refrigeration system which is said to offer the possibility of impressive energy and financial savings for convenience stores.
