Document Type and Number:
WIPO Patent Application WO/2021/051758
Kind Code:
A1
Abstract:
The invention relates to the technical field of air conditioning, and specifically relates to a control method for an air conditioning system, and an air conditioning system. The invention aims to solve the problems in existing air conditioning and refrigeration systems in which the heat exchange efficiency between a refrigerant and chilled water is low and the chilled water is easy to freeze. The control method for an air conditioning system, and the air conditioning system are provided by the invention to solve the problem. The method comprises comparing the acquired actual evaporation temperature of a whole-unit evaporator of the air conditioning system with a preset temperature, and adjusting, on the basis of a comparison result, the evaporation temperature of the whole-unit evaporator. In this way, the evaporation temperature of the whole-unit evaporator is kept within a preset temperature range, thus ensuring that the evaporation efficiency of the whole-unit evaporator is at a high level, and preventing chilled water from freezing due to the evaporation temperature being too low. The invention ensures the evaporation efficiency of the whole-unit evaporator by means of controlling the evaporation temperature thereof, and prevents the chilled water in the air conditioning system from freezing, thereby improving user experience.
