摘要： A cooling apparatus has a heat exchanger for performing heat exchange between cooling water and fluid, and a flow rate regulator valve for regulating a flow rate of either the cooling water or the fluid which pass through the heat exchanger. A cooling temperature of the fluid is preset. A temperature of the cooled fluid is detected, and an opening degree of the flow rate regulator valve is changed when there is a difference between the detected temperature and the preset temperature. Simultaneously, either a temperature difference of the cooling water and the fluid or a flow rate of the cooling water is detected. The opening degree of the flow rate regulator valve is corrected or compensated on the basis of a result of the detection, thus enabling suitable temperature control of the fluid in accordance with a variation of the temperature or flow rate of the cooling water.

摘要： A heating portion is cooled by a fluid, thereby effecting a temperature control. The temperature of the fluid is measured at the time of starting of a system, and the measured fluid temperature is compared with a set temperature. In accordance with the result of the comparison, the timing of starting the operation of LSI chips and the timing of starting the operation of a refrigerator are controlled.

摘要： A control system for controlling cooling equipment comprising a refrigerant circuit for cooling water by heat exchange, a plurality of cooling modules in a backup relationship with an adjusting apparatus for adjusting the cooling capability of the refrigerant circuit and a controller controlling the adjusting apparatus for adjusting the cooling capability, a control module having a coolant temperature sensor and a controller for calculating a cooling capability control command based on the value detected by the coolant temperature sensor. The controller in one of the cooling modules controls the adjusting apparatus and on the cooling capability control commend transmitted from the controller in the control module. Each of the cooling modules has a coolant temperature sensor for detecting the same coolant temperature as detected by the coolant temperature sensor of the control module so that, when an abnormality occurs in the coolant temperature sensor in the control module, the controller in the control module calculates the cooling capability control command based on the value detected by the coolant temperature sensor in the cooling module. The control system is therefore capable of performing a backup operation effective for the occurrence of an abnormality in the control module.

摘要： A water chilling apparatus comprising a plurality of chilling modules each having a refrigerating cycle mainly composed of a compressor, a condensor, an evaporator and an expansion mechanism, and a control module having a water pump for feeding, to an object to be chilled, chilling water cooled down by the evaporator of each chilling module, a detector for detecting a temperature of the chilling water and a water temperature controller. A chilling ability of each chilling module in response to a variable frequency is kept at substantially the same level. A capacity of the compressor of each chilling module is variably controlled in a range between an upper limit capacity and a lower limit capacity. The water temperature controller is used to calculate a whole necessary capacity value needed in the compressors of all the chilling modules as a function as a deviation between a set value of the chilling water temperature and a chilling water temperature detected by the detector. The number of the operated chilling modules is controlled in response to the whole necessary capacity value and the upper and lower capacities of each of the chilling modules. The capacity of the compressor of each of the cooling modules is controlled so as to have a capacity value obtained by equally distributing the calculated whole necessary capacity value by the number of the operated chilling modules.
