Based on VAV air-conditioning system, the paper presents the conceptual design of the whole control system with the help of construction project of HVAC comprehensive laboratory in the building environment and equipment engineering department of Shanghai University for science and technology. Corresponding control procedure and operate interface are developed to carry on constant-pressure and variable pressure control algorithm on this experimental platform. The controlling performance of constant pressure and variable pressure controlling algorithm are examined by experimental data. Following that, the application of variable pressure control method in the actual project tentatively is analyzed with improvable methods proposed. This paper also carries on some experiments on the performance of constant-pressure and variable pressure control algorithm, which proved the energy- saving potential of the VAV air-conditioning system and supply air fan in quantity.

The characteristic curves of valve position, air volume of VAV terminals and the static pressure of supply air are found from a series of experiments. It can be concluded that the control method of const static pressure can make very good result and the control method of variable static pressure summarized in this paper is feasible totally.
