Title:
NATURAL CIRCULATION TYPE COOLING SYSTEM AND CONTROL METHOD
Document Type and Number:
Japanese Patent JP2015200433
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a natural circulation type cooling system.SOLUTION: A cooling system comprises: an indoor heat exchange unit which is installed indoors; an outdoor heat exchange unit which is installed outdoors; a circulation system which naturally circulates a cooling medium between the indoor heat exchange unit and the outdoor heat exchange unit; a capacity estimation unit which estimates cooling capacity of the indoor heat exchange unit; and a capacity control unit which controls peripheral devices included at least in any of the indoor heat exchange unit, the outdoor heat exchange unit or the circulation system on the basis of a cooling load required for the indoor heat exchange unit and the cooling capacity. The capacity estimation unit includes a function to obtain the cooling capacity that the indoor heat exchange unit is planned to fulfill from a temperature of a fluid cooling medium supplied to the indoor heat exchange unit and a temperature of a cooling object. The capacity control unit includes a function to control at least one of the peripheral devices in a manner that curbs the cooling power of the indoor heat exchange unit when the cooling capacity is larger than the cooling load.
