【Abstract】 To make the VAV system controlling highly efficient, energy-saving and comfortable, the authors study the ratio-control of fresh-air and indoor-air, the temperature-control and humidity-control, the frequency-control of fans in the four-pipe-system. From the point of view of intelligent building controlling we analyse the conversion condition of all kinds of work-point by using enthalpy-humidity chart, adjusting the wind-system or the water-system to meet the demand of air-condition design. Some suggestions for the control of transition seasons are presented in the end.更多还原
