The benefits of hydrocarbon refrigerants in ultra low freezers

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.

Increased efficiency

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 freezers have an extremely high COP. The efficiency of the ECO 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.

Extremely low environmental impact

As an established expert in the manufacture of Ultra-low and Biomedical freezers, Panasonic is dedicated to providing customers with the most energy efficient and environmentally friendly equipment. With the introduction of hydrocarbon refrigerant technology to our freezer range, Panasonic is providing a solution for all laboratories looking to reduce their environmental impact. As well as being non-ozone depleting, hydrocarbons have short atmospheric lifetimes and extremely low global warming potentials. The atmospheric lifetime of a gas relates to the average time that a molecule resides in the atmosphere before it is removed by chemical reaction or deposition. A short atmospheric lifetime means that the refrigerant is removed from the atmosphere quickly, resulting in a lower global warming.
