Phase change materials for domestic refrigerators to improve food quality and prolong compressor off time.
Author(s) : SUBRAMANIAM P., TULAPURKAR C., THIYAGARAJAN R., et al.
Summary
The method and design of a novel dual evaporator based domestic refrigerator with phase change materials (PCM) which provide thermal storage (TS) is presented. The usage of PCM as a TS will help to improve the COP of new refrigeration cycle by introducing a new sub cooling routine. This improvement by sub cooling can be done for single evaporator refrigeration system or with even a dual evaporator system for a refrigerator/freezer combination. Because of prolonging of the compressor off time by using the latent heat of energy of the PCM we can have better food quality due to lower hysteresis cycles of on/off for a given period of operation. The authors have made system level modelling of the freezer/fresh food type domestic refrigerator and have also simulated the energy consumption using the new refrigeration cycle with sub cooling using PCM. Based on system design and modelling the authors have made experimental refrigerator prototype with new refrigeration cycle with PCM based TS and heat exchangers in the freezer and fresh food section. Test results and improvements in food quality are also presented. The energy efficiency results are also discussed.
