AIR HEATING/COOLING HEAT PUMP sketch of a heat pump receiving outdoor air, determine the following. Assume the heat capacity of air is 1.0 kJkg-K. (a) If the supply air mass flow rate and temperature (Point 3) are 0.8 kg/s and 39.7"C, and the return air temperature (Point 4) is 22C, the heating rate of the heat pump is kW. (Express your answer to one decimal place.) itthere is NO heat reco e yurt and 25% of the air is exhausted and replaced with outdoor air at 07"С Point 1 since there is no H U (c) If there IS a heat recovery unit with an effectiveness of 0.8 installed in the system as shown in the dagram above, the amount of heat recovered trom the exhaust air is (d) With the above conditions, the temperature at Point 1 is the outdoor air load is kW. (Express your answer to one decimal place.) kW. (Express your answer to one declmal place.)
