An evaporator and heater core are provided within a cooling unit so that the flow rate of the heating medium flowing into the heater core can be adjusted with a 3-way valve. The target outlet temperature of the air discharged into the space being temperature controlled is calculated based upon the temperature of the air taken into the cooling unit and the temperature setting that is set at the temperature setting device. The openness of the 3-way valve is adjusted in such a manner that the temperature of the air outlet from the cooling unit is adjusted toward the target outlet temperature when the intake air temperature has entered a specific temperature setting range. Also, for each storage compartment, unit fans, an evaporator and a heater core are provided, housed within a unit case. The evaporators are connected in parallel to a common compressor to adjust the flow rates of the coolant with a solenoid valve. The heater cores are connected in series so that they share a common heat source and a bypass passage is provided that bypasses the heater cores to adjust the flow-rate ratios between the individual heater cores and the bypass passage with a 3-way valve.
