Consider the following statements
In the case of a varpour compression machine if the condensing temperature of the refrigerant is closer to the critical temperature then there will be
1. Excessive power consumption
2. High compression
3. Large volume flow
Of these statements
Option (A)
1, 2 and 3 are correct
Option (B)
1 and 2 are correct
2 and 3 are correct
1 and 3 are correct
Correct Option:
Question Solution:

The closer we more to critical temperature higher is the amount of work required for compression. If the refrigeration effect is same the COP decreases. Even on the diagram the refrigerating effect will decrease
