The invention provides a descaling method and an evaporation cooling heat exchanger assembly, and relates to the technical field of refrigeration. The descaling method comprises the step that a firstevaporation pressure value and a second evaporation pressure value are received, the first evaporation pressure value represents average evaporation pressure of a refrigerant in a heat exchanger during a first preset cycle, the second evaporation pressure value represents average evaporation pressure of a refrigerant in the heat exchanger during a second preset cycle, and the first preset cycle isadjacent to the second preset cycle and is set before the second preset cycle. A spraying device is controlled to switch spring gears according to the first evaporation pressure value and the secondevaporation pressure value so that the spraying amount of the spraying device can be adjusted. The invention further provides the evaporation cooling heat exchanger assembly which can execute the descaling method. The descaling method and the evaporation cooling heat exchanger assembly provided by the invention can quickly achieve descaling of a heat exchanger.
Description
technical field [0001] The invention relates to the technical field of refrigeration, in particular to a descaling method and an evaporative cooling heat exchanger assembly. Background technique [0002] At present, the evaporative cooling plate and tube heat exchanger unit will have fouling after running for a period of time. The evaporative cooling plate and tube heat exchanger mainly evaporates the heat by spraying water on it, and the cooling water used for spraying itself contains a large amount of calcium, magnesium and chloride ions, which increases the concentration of the water, resulting in the precipitation of high-concentration salt in the Fouling forms on the surface, reducing the heat transfer efficiency of the evaporative cooling plate and tube heat exchanger. [0003] In addition to anti-scaling measures, there are also descaling measures. Descaling mainly includes chemical agents and manual mechanical cleaning. Chemical agents have a certain corrosive eff...
