A central air-conditioning cooling water circulation pump control system for monitoring real-time energy consumption

Abstract

The invention discloses a central air conditioner cooling water circulating pump control system capable of monitoring real-time energy consumption. The central air conditioner cooling water circulating pump control system is characterized by comprising two frequency converters and three cooling water circulating pumps; the frequency converters comprise the frequency converter U1 and the frequency converter U2; the cooling water circulating pumps comprise the 1# main water pump, the 3# main water pump and the 2# backup water pump; the control system further comprises an energy consumption counting module which comprises a three-phase electricity meter; and the three-phase electricity meter is connected into the wire inlet end of a main loop. The control system can achieve multi-point control and switch between the manual starting mode and the automatic starting mode. The control system can monitor the energy consumption condition of the system in real time, and energy saving is facilitated.

Description

technical field [0001] The invention relates to the technical field of central air-conditioning cooling water control, in particular to a central air-conditioning cooling water circulating pump control system for monitoring real-time energy consumption. Background technique [0002] In order to have a more comfortable indoor environment, central air-conditioning has become an indispensable electrical device in people's work and life. However, the use of air-conditioning consumes a lot of energy. The module of energy consumption statistics cannot understand the energy consumption of each component inside the air conditioner in detail and accurately, so that there is no targeted research direction in the energy-saving design. Contents of the invention [0003] In order to overcome the deficiencies in the prior art above, the purpose of the present invention is to provide a central air-conditioning cooling water circulating pump control system that monitors real-time energy c...
