Consider the following statements in the thermoelectric refrigeration, the coefficient of performance is a function of
1. Electrical conductivity of materials
2. Pelletier coefficient
3. See back coefficient
4. Temperature at cold and hot junctions
5. Thermal conductivity of materials
Of these statements
Option (A)
1, 3, 4 and 5 are correct
Option (B)
1, 2, 3, and 5 are correct
1, 2, 4 and 5 are correct
2, 3, 4 and 5 are correct
Correct Option:
Question Solution:
In thermoelectric refrigeration system COP is the independence of the size of thermoelectric refrigeration and this make it particularly attractive to use pettier cooling when cooling capacity is high
COP decreases with increase in temperature difference
