In a mechanical refrigerator, the low temperature coils are at a temperature of `-23^(@)` C and the compressed gas in the condenser has a temperature of ` 27^(@)C`. The theoretical coefficient of performance is :-

A

5

B

8

C

6

D

6.5

Text Solution

Verified by Experts

The correct Answer is:
A
`beta=(T_2)/(T_1-T_2)=(-23+273)/((27+273)-(-23+273))=(250)/(50)=5`
