Abstract

The invention discloses a control method and a device of an evaporative condensing unit. The method comprises the steps of obtaining environmental parameters in a heat exchange tube of a unit condenser according to a triggered instruction for turning on a unit descaling mode, and controlling the operating state of the unit according to the obtained environmental parameters in the heat exchange tube of the condenser so as to descale the surface of the unit condenser. By using the control method, the problem of influence on the performance of the unit because scale is generated when the evaporative condensing unit is operated for a long time in the prior art is solved, and the heat exchange coefficient of the condenser and the refrigerating effect of the unit are increased.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a control method and device for an evaporative condensing unit. Background technique [0002] In the prior art, the evaporative condensing unit is greatly affected by water fouling. After long-term operation, the surface of the condenser continuously evaporates water, forming thick dirt on the surface, and the thickness directly increases the fouling coefficient, thereby affecting the performance of the condenser. The heat transfer coefficient will cause the performance of the unit to decline. [0003] Aiming at the problem in the related art that the evaporative condensing unit produces scale after long-term operation and affects the performance of the unit, no effective solution has been proposed yet. Contents of the invention [0004] The present invention provides a control method and device of an evaporative condensing unit to at least solve the problem in the prior...
