Question

What is principle of cascade cooling ??

Answer 1

The cascade refrigeration system is a freezing system that uses two kinds of refrigerants having different boiling points, which run through their own independent freezing cycle and are joined by a heat exchanger

Answer 2

Principle behind the cascade refrigeration system in which they different cooling system separated by heat exchange and they run on their independent freezing cycle.

Explanation:

The improvement in efficiency is seen by combining two kinds of refrigerants with different temperature characteristics.Energy is also saved since the cooling system is different for higher and low temperature. Higher temperature make use of ammonia refrigerant and lower temperature make use of HFC refrigerant.
