Thermal characteristic measuring method and system of air conditioning system, terminal and storage medium

Abstract

The invention provides a thermal characteristic measuring method and system of an air conditioning system, a terminal and a storage medium. The air conditioning system comprises a water chilling unit, a coil pipe and a pipeline. The thermal characteristic measuring method comprises the following steps: acquiring each thermal characteristic initial parameter of the air conditioning system in real time, and acquiring the outlet water temperature of the water chilling unit according to the thermal characteristic initial parameters of the air conditioning system; acquiring the outlet water temperature of the pipeline according to the water outlet temperature of the water chilling unit; acquiring the air supply temperature of the coil pipe according to the outlet water temperature of the pipeline; and acquiring a thermal characteristic measuring result of the air conditioning system according to the outlet water temperature of the water chilling unit, the outlet water temperature of the pipeline and the air supply temperature of the coil pipe, wherein the thermal characteristic measuring result is a dynamic change process of conveying cold energy into a room by the air conditioning system after a refrigerator side control strategy is implemented. According to combination of measuring results of the water chilling unit, the coil pipe and the pipeline, compared with the prior art, the method has higher scene applicability and universality, and the measuring method is more effective and faster.

Description

technical field [0001] The invention relates to the field of air conditioning systems, in particular to a method, system, terminal and storage medium for measuring thermal characteristics of an air conditioning system. Background technique [0002] With the development of science and technology, the national policy and social level have higher and higher requirements for environmental protection and energy conservation. In terms of air-conditioning systems, the existing technology often adopts terminal control strategies to reduce the cooling load of air-conditioning peak hours, so as to achieve the response effect of reducing the electricity demand of air-conditioning peak hours. These terminal control strategies essentially use the thermal characteristics of the building itself to realize the storage and release of cold energy to complete the transfer of cooling load. However, these existing strategies have technical problems such as slow response, "only monitoring but no...

AI Technical Summary

Problems solved by technology

However, these existing strategies have technical problems such as slow response, "only monitoring but not control", simplifying or ignoring the dynamic thermal characteristics of the air conditioning system, etc.

At the same time, the description of the compressor, expansion valve and condenser in the chiller in the prior art is relatively complicated, and it is not universal due to the limitation of the form of the cooling side
