Abstract

A heat exchange cooling water system provided by the present invention includes a cooling water storage tank, a heat exchanger, a circulating water pump and a water cooling unit, wherein the cooling water storage tank is connected to a heat exchanger, and the heat exchanger is connected to a circulating water pump The circulating water pump is connected to the water cooling unit, and the water cooling unit is also connected to the cooling water storage tank to form the closed circulation system. The system overcomes the defects in the existing open cooling system that the cooling water is easily polluted and affects the normal operation of the equipment. Further, the temperature of the cooling water at the outlet of the circulating water pump is collected by the temperature sensor, and the temperature value is converted into an electrical signal and transmitted to the electric three-way regulating valve, and then the high-temperature cooling water entering the circulating water pump is controlled by the electric three-way regulating valve The return water flow rate of the high-temperature cooling water can be used to increase or decrease the temperature of the cooling water before entering the water-cooling unit to meet the standard state requirements.

Description

technical field [0001] The present invention relates to the technical field of air-conditioning systems, in particular to a heat-exchange cooling water system and a control method that utilizes tap water pipe networks and cooling water to perform heat exchange for chillers. Background technique [0002] The traditional water-cooled chiller uses water as the cooling medium, and its related devices include cooling towers, cooling water circulation pumps, pipelines and valve systems, etc. After the cooling water exchanges heat with the air-conditioning and refrigeration equipment, it needs to be sent to the cooling tower, where it is sprayed onto the surface of the heat-dissipating material to make it contact with the air. At this time, a sensible heat exchange occurs between the hot water and the cold air, and at the same time part of the hot water is evaporated, and the latent heat of evaporation is discharged into the air, and finally the cooled water falls into the tank and...
