<p><P>PROBLEM TO BE SOLVED: To provide an electronic equipment cooling device preventing dew condensation with a simple configuration. <P>SOLUTION: A exhaust heat temperature of electronic equipment 3 inside a cabinet 11 is detected, refrigerant supply to an evaporator 21 is stopped when the exhaust heat temperature becomes a setting exhaust heat temperature T0 prescribed in a computer room or below at which dew is not condensed in the evaporator 21, and the refrigerant supply to the evaporator 21 is started when the exhaust heat temperature certainly exceeds the setting exhaust heat temperature T0. A refrigerant temperature passing through the evaporator 21 is detected, and operation of a compressor is controlled such that the refrigerant temperature becomes less than a setting refrigerant temperature TH prescribed in the computer room at which dew is not condensed in the evaporator 21. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
