Improving the energy efficiency of a vapour compression system using a phase change material.

Author(s) : AZZOUZ K., LEDUCQ D., GUILPART J., et al.

Summary

When heat transfer between an evaporator and the refrigerated area is unusually low (a typical example is by natural convection) and the vapour compression system is on/off regulated, adding a planar phase change material to an existing evaporator allows to improve the global efficiency. In this paper, the case of a household refrigerator is simulated as an example. Compared to the classical vapour compression system, the new design shows a significant increase of the COP, but also a limitation of the maximum refrigerating capacity transmitted to the refrigerated area. Other benefits and limits of this technology are discussed.
