Question
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
Open in App
Solution
Given,
Temperature of cold body,
T
2
=
−
23
∘
C
⇒
T
2
=
(
273
−
23
)
K
Temperature of compressed gas,
T
1
=
27
∘
C
⇒
T
1
=
(
273
+
27
)
K
Coefficient of performance,
β
=
T
2
T
1
−
T
2
⇒
β
=
273
−
23
(
273
+
27
)
−
(
273
−
