Abstract

As the problem of building energy consumption is becoming more and more obvious, and people's demand for indoor environment comfort is increasing, the optimal design of building heating ventilating and air conditioning (HVAC) system becomes extremely urgent. This article focuses on the optimal design of building HVAC system based on digital twinning technology. Firstly, this article expounds the research background, purpose and significance, and points out the limitations of traditional design methods. Through in-depth analysis of digital twin technology and the basic theory of building HVAC system, it shows that this technology is feasible and advantageous for HVAC system. Then the paper introduces the process of building HVAC system model construction based on digital twinning technology in detail, covering digital representation of physical entities, virtual model construction and data collection and transmission. Then, the optimization design strategy based on this model is put forward, the optimization goal is clear, the key influencing factors are analyzed and the optimization method is formulated. The practical case shows that this optimization design strategy can effectively improve the energy efficiency of the system, reduce energy consumption by about 15%-20%, and improve indoor comfort, which provides a feasible method for the optimal design of building HVAC system.
