Analysis of a domestic refrigerator cycle with an ejector.

Author(s) : TOMASEK M. L., RADERMACHER R.

Summary

In the paper an improved cooling cycle for a conventional domestic refrigerator-freezer utilizing an ejector for vapour precompression is analyzed using an idealized model. Its energy efficiency is compared to that of the conventional refrigerator-freezer system. Emphasis is placed on off-design conditions. The ejector-enhanced refrigeration cycle consists of two evaporators that operate at different pressure and temperature levels. The ejector combines the vapour flows exiting the two evaporators into one at an intermediate pressure level. The ejector cycle gives an increase of up to 12.4% in the COP compared to that of a standard refrigerator-freezer cycle.
