Case Study of Energy Diagnosis Simulation of Vav Ahu System Controls
نویسندگان
چکیده
Advanced control and operation of HVAC systems in buildings is one of the most promising energy efficient technologies. However, there is still significant energy saving potential in these systems. Energy savings can come from correcting deficiencies through building commissioning. This paper focuses on deficiencies in the controls of a variable air volume (VAV) air handling unit (AHU) system. This paper demonstrates how DeST, a building simulation tool, is used to detect faults and to optimize set points in VAV AHU system controls. Through a detailed case study, this research explores the methods and values of simulation in energy performance diagnosis. The case study described in this paper was carried out as part of a commissioning project of campus buildings.

Energy Efficiency and the Control and Simulation of VAV Systems
Variable air volume (VAV) systems are one of the most common air-conditioning system types for larger buildings in warm temperate climates and are likely to remain so for some time. However, VAV systems are heavily dependent upon control for their efficient operation and are particularly prone to system-wide failure as a result of the malfunction of individual components in the field. In this p...
متن کاملBayesian network based FDD strategy for variable air volume terminals
a r t i c l e i n f o This paper presents a diagnostic Bayesian network (DBN) for fault detection and diagnosis (FDD) of variable air volume (VAV) terminals. The structure of the DBN illustrates qualitatively the casual relationships between faults and symptoms. The parameters of the DBN describe quantitatively the probabilistic dependences between faults and evidence. The inputs of the DBN are...

متن کاملAutomated Fault Diagnostics for AHU-VAV Systems: A Bayesian Network Approach
Although it is widely accepted that 20%-30% of total HVAC energy in commercial buildings is wasted due to faulty or inefficient operation, there presently exist no widely adopted solutions to identify and remedy this waste. This lack of adoption is due primarily to the high upfront costs associated with the manual process of customizing commissioning solutions for each individual building. In o...
متن کاملDynamic Optimization of Integrated Operation Strategies for the Building Vav System and Night Ventilation Using the Simultaneous Collocation Method: a Case Study
This paper presents a systematic approach to address the dynamic optimization of integrated operation strategies for the building VAV system and night ventilation. The objective is to minimize the energy consumption of the cooling coil and fans in a typical summer day. In the optimization scheme, the physical model is developed per differential algebraic equations (DAEs). The simultaneous collo...
