Description

Technical Field

[0001] The utility model relates to the technical field of ice water units, in particular to an automatic control system for ice water units. Background Art

[0002] The water circulation system in the water inlet and outlet management system of the chiller refers to the water supply system in which the cooling water is exchanged with heat and cooled, and then recycled. It is mainly composed of the chiller, water inlet pipe, water outlet pipe, water pump, etc. It is a cooling water system that uses water as a cooling medium and circulates. The cooling water system is an extremely important link in the electromechanical equipment industry, which is related to the safe operation and service life of the cooled electromechanical devices. It is also a weak link that is easily overlooked. For example, in the cooling system of high-power power electronic devices, it is a very necessary supporting equipment. The chiller is a water cooling device that can provide a constant temperature, constant flow and constant pressure. The chiller injects a certain amount of water into the machine, cools the water through the refrigeration system, and then the circulating water pump inside the machine injects low-temperature frozen water into the equipment that needs to be cooled. The frozen water takes away the heat inside the equipment, and then the high-temperature hot water flows to the water tank again for cooling, realizing the circulating cooling of the electromechanical equipment.

[0003] However, the chiller unit is a key equipment in the existing production process. It is prone to abnormal shutdown when in operation for a long time. In addition, due to the current use of water pumps, they are directly exposed to the outside and lack the necessary protection, which makes the water pumps easily damaged by external forces. At the same time, the speed of the water supply pump cannot be adjusted in real time according to demand, so that the water pump always maintains a constant speed, resulting in increased energy consumption.
