    Q=1312.5 W

    Explanation:

    Given that

    Cooling load or power input = 750 W

    COP=1.75

    We know that COP can be given as

    COP is the ratio of cooling effect to the input power.

    Lets take cooling effect is Q. So now by using COP formula

    COP=Q/750

    1.75=Q/750

    Q=1312.5 W

    So the cooling effect produce by air conditioning will be 1312.5 W.

    The net effect on laboratory, the laboratory temperature will reduce.
