Embodiment approach

[0062] As a preferred implementation of the above-mentioned control method provided in this embodiment, the control method further includes: acquiring the actual flow of chilled water in the air conditioning system; comparing the actual flow with a preset flow threshold; As a result of the comparison, the flow of the chilled water is controlled so that the flow of the chilled water is not less than a preset flow threshold.

[0063] Exemplarily, from the results of the above experiments, it can be known that the main factors affecting the freezing of the chilled water include the evaporation temperature of the whole machine evaporator 1 and the flow rate of the chilled water. On the basis of ensuring the evaporation efficiency of the complete evaporator 1 by controlling the evaporation temperature of the refrigerant, in order to prevent the freezing water from freezing more effectively. A preset flow threshold can also be set so that the chilled water flow is always greater tha...

Abstract

The invention relates to the technical field of air conditioners, in particular to a control method of an air conditioning system and the air conditioning system. The control method and the air conditioning system aim to solve the problems that the heat exchange efficiency of a refrigerant and chilled water in an existing air conditioner refrigeration system is low and the chilled water is likelyto be frozen. The invention provides the control method of the air conditioning system and the air conditioning system for solving the problem. The obtained actual evaporation temperature of a whole machine evaporator of the air conditioning system is compared with a preset temperature, and the evaporation temperature of the whole machine evaporator is adjusted based on the comparison result, so that when the evaporation temperature of the whole machine evaporator is maintained within a certain preset temperature scope, the evaporation efficiency of the whole machine evaporator is maintained at a high level, and the problem that the chilled water is frozen due to excessively low evaporation temperature can be avoided. Therefore, the evaporation efficiency of the whole machine evaporator isensured by controlling the evaporation temperature of the whole machine evaporator, the chilled water in the air conditioning system can be prevented from being frozen, and the use experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning system control method and the air conditioning system. Background technique [0002] The air conditioning and refrigeration system is used to reduce the temperature in the room to meet people's normal demand for temperature. [0003] An existing air-conditioning and refrigeration system includes a complete evaporator, a condenser, a compressor, an end evaporator and a fan; The two ends of the refrigerant coil are respectively connected to the compressor and the condenser, and the compressor is connected to the condenser; the two ends of the chilled water coil are respectively connected to the water inlet and outlet of the end evaporator, and the end A fan is installed on the evaporator. The refrigerant in the refrigerant coil evaporates and absorbs heat to lower the temperature of the water in the chilled water coil, and the cooled chilled water ent...
