Natural hydrocarbon refrigerants provide more efficient cooling due to their high latent heat of evaporation. As a result, smaller compressors can be used leading to greater energy efficiency. With exceptionally low global warming potential natural refrigerants are also better for the environment.
The efficiency of a freezer can be measured as a coefficient of performance (COP) which is a ratio of the cooling provided to the electrical energy consumed.
Panasonic Eco Line freezers have an extremely high COP. The efficiency of the Eco Line freezers is a result of the high latent heat of evaporation of the hydrocarbon refrigerants. This value relates to the amount of heat required to turn a liquid into a gas – essentially the energy needed to break the forces which bind the refrigerant molecules together in a liquid state. As a larger amount of heat energy is required to break the binding forces between hydrocarbon molecules, these refrigerants remove heat more efficiently from the freezer cabinet than if a traditional refrigerant was used.
Reduced running costs
The use of highly efficient hydrocarbon refrigerants results in reduced energy consumption and therefore lower running costs. With key equipment and instrumentation operating continuously laboratories are able to significantly reduce running costs by investing in energy efficient facilities. Panasonic designs and builds advanced preservation systems to deliver maximum cost efficiency while maintaining the reliability and performance necessary for reliable storage of valuable research and clinical samples.
Alongside a host of other energy saving features, the efficient cooling delivered by hydrocarbon refrigerants can allow smaller compressors to be used leading to significant reductions in energy use and running costs. In addition, more efficient refrigeration systems dissipate less heat to their surroundings reducing the requirement for air conditioning which can lead to further savings.
