Title:
ENERGY-SAVING CONTROL DEVICE, ENERGY-SAVING CONTROL METHOD, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/130619
Kind Code:
A1
Abstract:
An energy-saving control device, an energy-saving control method, and a storage medium, wherein the energy-saving control device comprises a control module and an acquisition assembly. The control module is in communication connection with the acquisition assembly and an electronic expansion valve, respectively; the acquisition assembly is used for acquiring monitoring data of a refrigerating system; the monitoring data comprises back pressure information of a compressor, outlet high pressure information of a condenser and environment temperature information in the refrigerating system; and the control module adjusts an opening degree of the electronic expansion valve according to the monitoring data, so that a refrigerating capacity of the refrigerating system and load heat are balanced. According to the present invention, the opening degree of the electronic expansion valve can be adjusted in real time according to the back pressure information of the compressor, the outlet high pressure information of the condenser and the environment temperature information in the refrigerating system, so that the refrigerating capacity of the refrigerating system and the load heat are balanced, the flow and energy consumption of the compressor are effectively reduced, and there is no need to use a heater for temperature intervention during the balance process of the refrigerating capacity thereof and the load heat, so that the energy consumption of the refrigerating system is effectively reduced, thereby achieving the energy-saving purpose.
