Title:
SELF-CLEANING CONTROL METHOD FOR AIR CONDITIONING SET
Document Type and Number:
WIPO Patent Application WO/2021/223501
Kind Code:
A1
Abstract:
The present invention relates to the technical field of self-cleaning of air conditioners, and specifically provides a self-cleaning control method for an air conditioning set. The present invention aims at solving the problem that existing self-cleaning methods for an air conditioning set are all provided for a single heat exchanger. For this purpose, the self-cleaning control method of the present invention comprises: enabling a coil temperature of a first heat exchanger to be lower than or equal to a first preset temperature and higher than a second preset temperature; enabling the coil temperature of the first heat exchanger to be lower than or equal to the second preset temperature; enabling a refrigerant in a main circulation loop to reversedly circulate; enabling a coil temperature of a second heat exchanger to be lower than or equal to a third preset temperature and higher than a fourth preset temperature; enabling the coil temperature of the second heat exchanger to be lower than or equal to the fourth preset temperature; and enabling the refrigerant in the main circulation loop to reversedly circulate again. In the present invention, by executing a set of control logic, the first heat exchanger and the second heat exchanger can be simultaneously self-cleaned, thus the effect of self-cleaning is ensured, and time and energy consumed during a self-cleaning process can also be effectively saved.
