INTRODUCTION
• Refrigerators and Air-conditioners satisfy the needs of present luxury and comfortness
• The conventional R & AC system uses electricity.
• The nonconventional way of power generation is solar energy. But a solar energy system
has low COP.
• The Combined Ejector-Vapor Compression Cycle eliminates these disadvantages in an eco-
friendly way.

Conclusions
In the Combined Ejector-Vapor Compression Cycle is:
There is a potential increase in the COP system by more than 50% over conventional cycles
The green refrigeration and air-conditioning prevents future ozone layer depletion.
Green house effect is reduced
It is a cost effective system and requires a low maintenance
