In a room for six persons, three fans of 200 W each and four lamps of 100 W each are fitted. Each person causes a heat load of 540 kJ/hour. The ventilation air enters the room through a cooler at a steady rate of 80 kg/hour with an enthalpy of 80kJ /kg. The air leaving the room has an enthalpy of 60 kJ/kg. Find the rate at which the heat is removed from the room by the cooler In a room for six persons, three fans of 200 W each and four lamps of 100 W each are fitted.
