Abstract: The local cooling unit according to an aspect of the present invention includes a housing having a cavity formed in the housing, an air inlet port which is provided in a bottom surface of the housing and which takes in exhaust heat air from the electronic device, an evaporator which is provided in the housing and which evaporates a refrigerant by heat exchange with air sucked in from the air inlet port to cool the air, the refrigerant passing through an inside of the evaporator, an air outlet port which is provided in a side surface of the housing and which exhausts the air cooled by the evaporator, and a fan which is provided on a side of the air inlet port or a side of the air outlet port of the housing and which moves the air from the air inlet port to the air outlet port.

Abstract: A cooling system for electronic equipment includes an evaporator cooling the electronic equipment, a blower making air heated by the electronic equipment flow into the evaporator, and a condenser condensing a refrigerant to be supplied to the evaporator and also includes a refrigerant liquid pipe guiding a liquefied refrigerant from the condenser to a lower part of the evaporator, a refrigerant gas pipe guiding the refrigerant which evaporates by cooling the electronic equipment from an upper part of the evaporator to the condenser, a refrigerant flow rate control valve controlling a flow rate of the refrigerant flowing into the evaporator, a temperature sensor detecting a temperature of air obtained after passing through the evaporator, and a controller for control valve controlling the control valve on the basis of a detection value of the temperature sensor.

Abstract: A refrigerant circulation apparatus includes: an evaporator which evaporates a refrigerant; a blowing device which blows air to the evaporator; a condenser configured to condense the refrigerant evaporated by the evaporator; a blower failure detecting device which detects failure of the blowing device; a heat medium flow rate control valve which controls a flow rate of a heat medium supplied to the condenser, the heat medium for cooling the refrigerant; a condenser refrigerant liquid temperature sensor which detects a temperature of the refrigerant which is supplied to the evaporator from the condenser; and condenser side refrigerant temperature control device which lowers a setting temperature of a condenser side externally inputted temperature and controls the heat medium flow rate control valve so that a measured value of the condenser refrigerant liquid temperature sensor becomes equal to the lowered setting temperature, when receiving a failure signal from the blower failure detecting device.
