Optimal Control of Water Valve in AHU Based on Actual Characteristics of Water Valve

Reasonable operational control of AHU (Air Handler Units) requires the actual working characteristics of the water valve. However, in the current engineering, it is usually based on the simulation of the hypothetical working characteristics of the water valve. The hypothetical characteristics of the equipment are often different from their actual characteristics. As a result, the expected control scheme is not effective in the actual operation. In this paper, applying the operational control scheme for AHU, which was based on the hypothetical characteristics of the water valve, to control the actual water valve, the effects obtained might be different from the expected effects when there were different room load characteristics. Therefore, an optimized method for AHU control based on the actual characteristics of the water valve was proposed according to different room load characteristics.
