Method for controlling flow rate of valve according to demanded heat quantity using a prediction model of heat transfer

摘要

The present invention relates to a method for controlling a valve flow rate according to a required heat quantity using a heat transfer prediction model that can simply and accurately control a valve flow rate according to a required heat quantity using a heat transfer prediction model for an air conditioner installed in the field. To this end, the present invention provides a comparison step of comparing the actual design air volume of the actual air conditioner installed in the field with the reference design air volume of the reference air conditioner stored in advance; a reference product selection step of selecting a reference product of a reference air conditioner having a design air volume close to the actual design air volume from among the standard air conditioner products; a heat transfer amount-flow curve calculating step of calculating a non-dimensionalized heat transfer amount-flow curve of the actual air conditioner by applying a heat transfer prediction model based on reference information including design factors according to the reference product; And, the valve flow rate control method according to the required heat quantity using a heat transfer prediction model including a valve flow rate control step of adjusting the flow rate of the fluid passing through the valve according to the required heat quantity based on the dimensionless heat transfer amount-flow curve provides
