Determination method and device for air conditioning system configuration

Abstract

The invention discloses a determination method and device for an air conditioning system configuration. The method comprises the following steps of: acquiring a preset option of a to-be-designed air conditioning system configuration input by a user, wherein the preset option of the to-be-designed air conditioning system configuration comprises a type, a refrigerant, an operating mode, an EER range, a rated refrigerating capacity range, the type and parameter of a condenser, an evaporator parameter and a compressor parameter; in a pre-established air conditioning configuration model library, searching for a historical air conditioning product matched with the preset option of the to-be-designed air conditioning system configuration; and determining the refrigerant filling amount and a throttling device of the searched historical air conditioning product, and taking the refrigerant filling amount and the throttling device as those corresponding to the pre-designed air conditioning system. According to the technical scheme disclosed by the invention, the workload of air conditioner design personnel can be reduced effectively, and the work efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of air-conditioning design, in particular to a method and device for determining the configuration of an air-conditioning system. Background technique [0002] At present, in the development and matching stage of air-conditioning products, it is necessary to select the material parameters of various accessories, such as compressors, throttling devices, two-stage (evaporator and condenser) heat-exchanging fin pipelines, etc., and the selection of various accessories It takes a long time for the collocation and many times to verify whether it can meet the energy efficiency requirements. During this period, it will take up a long time of experimental resources and material resources. Among them, it is difficult to accurately determine the amount of refrigerant perfusion and throttling devices, and it takes a lot of design. The staff put a lot of effort into repeated calculations and experiments many times. [...

During this period, it will take up a long time of experimental resources and material resources. Among them, it is difficult to accurately determine the amount of refrigerant perfusion and throttling devices, and it takes a lot of design. The staff put a lot of energy to repeat calculations and experiments many times

[0003] That is to say, in order to improve the performance or reliability of air conditioners, when developing new products, designers need to do a lot of verification work repeatedly to obtain reliable system configurations of new products, and the work efficiency is low.
