According to the method, the cause and the type of the contradictory conflict in the controlsimulation of the air conditioning system can be analyzed, and the abstract problem of the contradictory conflict can be converted into a concise and clear mathematical logic problem by establishing mathematical description of a system form and an inspection method, so that the automatic static contradictory pre-inspection method based on the computer program is formed.

Description

technical field [0001] The invention relates to the technical field of HVAC control strategy pre-inspection, in particular to an automatic pre-inspection method for HVAC control strategy. Background technique [0002] With the advancement of information technology, simulation technology has been more and more widely used in the field of research and analysis of central air-conditioning system performance and auxiliary air-conditioning system design. For example, currently, for air-conditioning systems with many types of equipment and complex forms, simulation software such as Trnsys, Modelica, and Flowmaster are often used to simulate the air-conditioning system in order to try to approach the actual performance of the equipment. [0003] However, in the simulation process of the central air-conditioning control system, there are often the following two types of problems: [0004] One is the complexity of automatic control system calculation: HVAC system simulation is a cou...

Problems solved by technology

[0004] One is the complexity of automatic control system calculation: HVAC system simulation is a coupling calculation process of hydraulic (flow control) and thermal (energy control), and the design of automatic control needs to consider the coupling characteristics of this system, so most software exists Computational Bias

[0005] The second is the complexity of parameter setting in the control strategy: the input of the control strategy involves a large number of parameters and the setting of the control process, which often results in certain manual errors that cannot be detected automatically

[0006] Although the setting of the simulation software control strategy can guarantee the validity of the entire system simulation to a certain extent, the calculation problems of the software itself and the errors of human input cannot be checked by the software itself, thus reducing the efficiency and correctness of the software.
