    "Increase in internal energy = energy consumed by fan " as the room is perfectly insulated and sealed.

    energy consumed by fan = power x time

    power of fan = 4HP = 4 x 745.7 W = 2982.8 W

    time = 1.5 hours = 1.5 x 60 x 60 = 5400 s

    energy consumed by fan = 2982.8 x 5400 = 16107120 J = 1.61x10^7 J

    Increase in internal energy is 1.61x10^7 J
