Document Type and Number:
WIPO Patent Application WO/2024/046016
Kind Code:
A1
Abstract:
Disclosed are an energy-saving controller and energy-saving control method for a water pump of a central air conditioning system. The energy-saving controller comprises: a compressor start/stop detection module, an input end thereof being connected to an output end of a main contactor of a power supply of a compressor of an air conditioning unit, the compressor start/stop detection module being used for detecting a start/stop state of the compressor and generating a compressor start/stop state signal, and the compressor start/stop state signal comprising a compressor operation state signal and a compressor operation stop state signal; and a driving module, an input end thereof being connected to an output end of the compressor start/stop detection module, an output end of the driving module being connected to an input end of a water pump control cabinet of a central air conditioning system, and the driving module being used for controlling, by means of the water pump control cabinet and according to the compressor operation stop state signal, a cooling pump to stop working and controlling, by means of the water pump control cabinet and according to the compressor operation state signal, the cooling pump to start to work. When the compressor is automatically stopped and is in a standby state, the present invention can control the cooling pump to stop working at the same time, thereby achieving the purpose of energy saving.
