Title:
冷却塔制御装置、冷却塔制御方法、及び熱源システム
Document Type and Number:
Japanese Patent JP6599182
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce cooling delay of a cooling water as far as possible, to prevent high pressure trip of the condenser of a refrigeration machine.SOLUTION: A cooling tower control device 4 is applied to a heat source system 1 including: a refrigeration machine 2 including a condenser 21 for cooling refrigerant with a cooling water W1; and a cooling tower 3 connected to the refrigeration machine 2, and configured to cool the cooling water W1 with rotation of a fan, wherein for a first predetermined period from starting of the refrigeration machine 2, a cooling water inlet target temperature at an inlet of the refrigeration machine 2 is set to a second target temperature smaller than a preset first target temperature by a first predetermined temperature, and a fan frequency of the cooling tower 3 is set based on the second target temperature.SELECTED DRAWING: Figure 1
