Title:
METHOD AND APPARATUS FOR CONTROLLING FREQUENCY STABILITY OF AIR CONDITIONER COMPRESSOR, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/015899
Kind Code:
A1
Abstract:
The present application provides a method and apparatus for controlling frequency stability of an air conditioner compressor, and an electronic device. The method for controlling frequency stability of the air conditioner compressor provided by the present application comprises: presetting a plurality of exhaust protection temperatures; presetting corresponding frequency control information on the basis of each exhaust protection temperature; obtaining the exhaust temperature of the compressor, and when the exhaust temperature is equal to the exhaust protection temperature, executing the frequency control information corresponding to the exhaust protection temperature; and if the executed frequency control information is one-time shutdown or two frequency reduction operations at a first rate, starting an exhaust protection mode. According to the control method for controlling frequency stability of the air conditioner compressor provided by the present application, a temperature difference between adjacent exhaust protection temperature points can be reduced, so that the frequency increasing and decreasing amplitude of the compressor is reduced, the compressor can quickly achieve stable running under severe working conditions, and the nose of the compressor is reduced; moreover, a temperature interval where the compressor keeps running at the current frequency can be increased, so that the compressor more quickly tends to stably run.
