A Performance Enhancement of Household Refrigerator using Phase Change Materials (PCMs)

Abstract

- In this study, a household refrigerator with ceiling type evaporator is considered to equip it with CTES system by using PCM. Domestic refrigerators are among the most widely used household appliances and a great portion of energy is used by these systems. Reduction of temperature fluctuation and enhancement of system performance is the main reason of using phase change materials (PCMs) in refrigeration systems. Different approaches have been used to improve the thermal performance of these systems by integration of PCM. A number of studies have focused on the application of PCM at evaporator for cold storage. So we are doing experimental investigation to improve energy efficiency of household refrigerator by introducing a new phase change material. Key Words: Thermal Energy Storage, Phase Change Material, Household Refrigerator, COP.
