HEAT SOURCE SYSTEM, AND DEVICE AND METHOD FOR CONTROLLING COOLING WATER SUPPLY DEVICE

摘要

In order to achieve a reduction in energy consumption in a cooling water supply device without using a database, an equipment control device (70a) of a cooling water supply device: uses the load of a refrigeration device, and a cooling water outlet temperature lower limit setpoint determined in accordance with the set temperature for the cooling water outlet of the refrigeration device, to set a cooling water inlet temperature lower limit setpoint; sets, as the cooling water inlet temperature setpoint, the higher of the lower limit setpoint and the cooling water inlet temperature lower limit value as determined from the outside wet-bulb temperature; and generates a control command for a cooling tower fan and a control command for the cooling water flow volume, so as to match the cooling water inlet temperature and the cooling water outlet temperature respectively with the cooling water inlet temperature setpoint and the cooling water outlet temperature lower limit setpoint which have been set.
