Question

Comparision of open and close refrigeration cycles

Answer 1

Answer:

Closed refrigeration system / Dense air refrigeration cycle

• Hence the size of compressor and expander is small compared to the open air system. The chance of freezing of moister and choke the valve is eliminated. In this system, higher coefficient of performance can be achieved by reducing operating pressure ratio.

Answer 2

Answer:

They are different.

Explanation:

In the open system, the air is directly led to the space to be cooled while in the closed system; air used is recirculated, air refrigerant is contained within pipes and is a component part of the system at all times.
