Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of water chillers, and particularly relates to a constant temperature water replenishing device applied to water chillers. Background Art
[0002] A water chiller is a water cooling device that can provide cooling water at a constant temperature, constant flow and constant pressure. A certain amount of water is injected into the water tank inside the machine in advance, and the water is cooled by the chiller's refrigeration system. The low-temperature cooling water is then pumped into the equipment to be cooled by a water pump. The chilled water in the chiller takes away the heat, and then the temperature rises and flows back to the water tank to achieve the cooling effect.
[0003] For the widely used high-temperature chillers (medium temperature 25-100℃), due to the influence of high-temperature evaporation, the cooling medium needs to be replenished regularly. The replenished cooling medium is generally room temperature, which has a large temperature difference with the working temperature of the chiller. Direct replenishment and mixing will cause the medium temperature of the chiller to change drastically, affecting normal use. At the same time, the widely used method is to shut down first and then replenish the medium, which affects the overall production progress. To this end, we provide a constant temperature water replenishment device for chillers to solve the above problems. Utility Model Content
