<p><P>PROBLEM TO BE SOLVED: To achieve an outside air cold recovery control system having inexpensive configuration by recovering outside air cold using an outdoor air conditioner. <P>SOLUTION: A thermometer 11 measures the temperature of cold water flowing through a cold water pipe 15 connected to the outdoor air conditioner 1, and air conditioning control part 9 controls an opening of a cold water valve 13 according to the cold water temperature. The outdoor air conditioner 1 performs heat exchange between the cold water flowing through the cold water pipe 15 and the outside air, thereby recovering coldness of the outside air to cool the cold water. When the temperature of cold water rises above a predetermined value, the air conditioning control part 9 controls the opening of the cold water valve 13 to be totally closed, thereby stopping outside air coldness recovery in the outdoor air conditioner 1 and cooling the cold water in a cold source device. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
