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

  1. Jul 12, 2011 #1
    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
