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
