Abstract

The invention discloses a control method for the refrigerating capacity of a cooling system, and the cooling system. The control method comprises the following steps: detecting a freezing water outlettemperature; determining a cooling return water temperature set value according to the freezing water outlet temperature; and controlling the refrigerating capacity according to the cooling return water temperature set value and the turn-on number or the turn-off number of fans at a cooling tower side of a cooling return water temperature control system. Therefore, on the premise that the refrigerating capacity achieves the need of end equipment, the proper turn-on number of the fans is selected, and a too high turn-on number of the fans of a cooling tower is avoided, so that the energy consumption is reduced, and the energy is saved.

Description

technical field [0001] The invention relates to the field of units, and in particular, to a method for controlling the cooling capacity of a cooling system and a cooling system. Background technique [0002] At present, in the winter and transition seasons when the outdoor temperature is low, in the field of refrigeration, natural cooling technology can be used for cooling to cool the terminal equipment. The natural cooling technology is to add a plate heat exchanger to the air conditioning system, so that the cooling water directly exchanges heat with the chilled water of the terminal equipment through the plate heat exchanger, and directly uses the outdoor low temperature environment for cooling to reduce the temperature of the chilled water. Since the natural cooling technology only needs to open part of the chiller or does not need to open the chiller, it can play a role in reducing energy consumption. Free cooling technology can be widely used in large data centers (su...
