What is Compression Ratio

Handbook of Research on Advances and Applications in Refrigeration Systems and Technologies
Difference between discharge pressure, usually equal condensation pressure and suction pressure, usually equal evaporation pressure divided by difference of the motive pressure and suction pressure.

The chapter presents the development of ejector refrigeration technology that strongly reduces the greenhouse gases emission by using natural refrigerants and also dramatically reduces the need for the electric power. This is accomplished by using free or inexpensive heat – either solar or waste heat, as the main source of energy instead of electricity. Nowadays, the thermal driven refrigeration system, especially with low-temperature heat source became more and more popular. The operation of the ejection cycle using low-temperature heat source can be considered as very attractive and the ejection cycles becomes truly competitive in comparison with the absorption refrigeration systems.
