Control method of multi-working-condition water chilling unit

Abstract

The invention discloses a control method of a multi-working-condition water chilling unit. Water system equipment is included, and the water system equipment comprises user equipment, a load water pump, a heat preservation water tank, a chilled water pump, a chiller, a cooling water pump and a cooling tower. The control method involves a control system. The output end of the control system is connected with a refrigerant circulation module, a power supply control module and a water circulation system module, the input end of the water circulation system module is connected with a flow meter module, the output end of the control system is connected with a numerical value checking module, the output end of the numerical value checking module is connected with a calculation checking module, and the input end of the calculation checking module is connected with a matching control module. The control method of the multi-working-condition water chilling unit is simple and clear, the controlaccuracy is improved, misjudgment is reduced, the use stability and safety of the water chilling unit are improved, refrigerant distribution is uniform, the unit performance is improved, and the control method is suitable for popularization.

AI Technical Summary

Problems solved by technology

The market lacks a control method for chillers that can independently control a single flowmeter. When multiple devices are used at the same time, it is easy to cause misjudgment, cause errors in the control system, and affect the normal use of the water chiller.
