Relationship between C.O.P. and outside air temperature

[timsea81]

Since the capacity of an air conditioner is a function of outside air temperature, does it follow that greater efficiency will be achieved by putting the condenser under shade rather than out in the open or on a hot roof? Or does the casing of the unit provide adequate shading to make this difference negligible?

COPmax = Te/(Tc-Te)
This is the maximum achievable COP.
Te is evaporator temperature
Tc is condenser temperature
Generally, Te = Trequired - 10
Tc = Tambient + 10
Yes ! it will
