Building static pressure control VAV Variable Measurement and Analysis of air-conditioning system

Energy saving percentage. In high summer load, such as 5 months to l0 months, variable static pressure control compared with Static Pressure Control, a 43 a '. 1l I {Xinjiang turned '1 strong pupil j; i Static Pressure Control of V in the air conditioning system, saving energy compared show a maximum energy of up to 23.4%, annual average energy saving of 8.6%. 4 Conclusions 1. Is put into actual use of the office building VAV air conditioning system was field-tested, air-conditioning system performance parameters by the building management system (BuildingManagementSystem) monitoring and recording, the use of variable static pressure controlled, compared with the fixed static pressure control, variable static pressure control of 8.6% annual average energy saving, not expected, but the building management system control software, the input variable is not static, and in the long run cost considerations, variable static pressure control is still an effective energy conservation measures. 2. Test data show that the existing variable air volume system, there are some problems, which may lead to poor energy efficiency reasons. The design of air handling units to obtain large amount of wind,[link widoczny dla zalogowanych], and the end of the valve air flow and air-conditioning cooling capacity provided by the district does not match the load. 3. Actual load and the air district's air supply valve at the end of the match for the air flow control valve installation position and temperature sensor tube design, layout and size of the merits of the implementation of variable static pressure control and greater energy efficiency impact. It is necessary to study different layout, the variable static pressure control air-conditioning system energy savings. References 1EnglanderSL. NorfordLK. Savhgfanenergy. insystems.
