Title:
METHOD FOR CONTROLLING COOLING MEDIUM OF MULTI-SPLIT AIR CONDITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/164203
Kind Code:
A1
Abstract:
The present invention relates to the technical field of air conditioning, and specifically relates to a method for controlling a cooling medium of a multi-split air conditioning system. In order to control an operation parameter of a compressor to ensure the stable and reliable operation of an air conditioning system, the control method for a cooling medium of a multi-split air conditioning system provided by the present invention comprises: acquiring the current operation value of a target parameter of a compressor while the compressor is operating; according to the current operation value of the target parameter of the compressor and the standard operational range of the target parameter of the compressor, calculating the degree of deviation of the target parameter of the compressor; and on the basis of the degree of deviation, selectively adjusting the degree of opening for an expansion valve of an outdoor unit or an expansion valve of an indoor unit; the standard operational range of the target parameter is the operational range of the target parameter that is defined by the normal operating state of the compressor. On the basis of an operation parameter of a compressor, the present invention adjusts in real time the degree of opening for an expansion valve of an outdoor unit or an expansion valve of an indoor unit so as to dynamically adjust the amount of cooling medium circulation for an air conditioning system and control the compressor to operate in a normal range, thus ensuring the system operates steadily and reliably.
