Problems solved by technology

[0002] In related technologies, the chiller water system is generally controlled by an external independent controller, and the linkage with the controller controlling the chiller is not strong. Control node, but the control is still not strong, unable to control the matching cooling tower butterfly valve system
Therefore, the controller of the water system of the chiller installed independently increases the actual cost of the chiller, and cannot realize complete automatic control of the chiller

Abstract

The invention discloses a control method and system of a water chilling unit. The water chilling unit at least comprises a water chilling unit water system and a compressor. The water chilling unit water system comprises a cooling water pump, a chilled water pump and at least one cooling tower. The control method comprises the steps that a control signal input by a user is received; and a plurality of control points and the compressor are controlled according to the control signal, a preset sequence or the inverted sequence of the preset sequence to start or stop the water chilling unit, wherein the preset sequence corresponds to starting of the water chilling unit. According to the control method of the water chilling unit, linkage of all control of the water chilling unit can be improved, the automation degree is high, and the use cost of the water chilling unit can be reduced.

Description

technical field [0001] The invention relates to the refrigeration field, in particular to a control method of a chiller and a control system of the chiller. Background technique [0002] In related technologies, the chiller water system is generally controlled by an external independent controller, and the linkage with the controller controlling the chiller is not strong. Control node, but the control is still not strong, unable to control the matched cooling tower butterfly valve system. Therefore, the independently installed controller of the water system of the chiller increases the actual use cost of the chiller, and cannot realize complete automatic control of the chiller. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the above-mentioned technologies at least to a certain extent. Therefore, the first object of the present invention is to provide a control method for a chiller. The method can improve the link...
