Résumé

Refrigeration equipment, whether commercial, industrial or domestic, experience transient loads. To satisfy the maximum load, systems are normally oversized and this results in high capital cost, inefficient operation and reduced reliability due to frequent on off cycling. The capacity of refrigeration equipment and compressor on-off cycling can be reduced through the development and optimum integration of phase change material (PCM) thermal energy storage within the equipment. This paper reports on results of investigations into the use of PCM in frozen food cabinets. Two ways of easily introducing PCM into existing cabinets were investigated. Both methods relied on the introduction of a secondary wall between the evaporator wall and the refrigerated space which contained the PCM. In the first method the PCM was contained in pouches attached to the evaporator and in the second method the PCM was contained in aluminium honeycomb. The results showed that the use of PCM reduced significantly the compressor cycling rate whilst maintaining product temperature below –18°C. The use of PCM in pouches incurred an energy penalty of 5% whereas the PCM in honeycomb resulted in energy savings of 2% compared to conventional cabinets without PCM storage.
