<p><P>PROBLEM TO BE SOLVED: To easily improve heating capacity especially in winter in an air conditioning facility. <P>SOLUTION: The air conditioning facility 1 makes outside air OA pass through an outdoor air conditioning unit 10 to supply the air to an indoor space 13. The outdoor air conditioning unit 10 is provided with a heat exchanger 25 for heating, a heat exchanger 26 for cooling, and a blower 27 for making the outside air OA thermally contact the heating heat exchanger 25 with the cooling heat exchanger 26 to supply the air to the indoor space 13. The air conditioning facility 1 is equipped with a water heater 30 for supplying hot water to the heating heat exchanger 25 and a heat source machine 40 for supplying coolant to the cooling heat exchanger 26. When the temperature of the outside air OA is within a predetermined low-temperature range, the facility is in a heating operation mode, and hot water is supplied from the water heater 30 to the heating heat exchanger 25. When the temperature of the outside air OA is within a predetermined high-temperature range, the facility is in a cooling operation mode, and the coolant is supplied from the heat source machine 40 to the cooling heat exchanger 26. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
