摘要:隨著人們對生活品質的高要求,使空調也隨之成為了必不可少的一部分。與此同時,空調系統的設備質量與性能的提高也成為必要。由于我們熟知的傳統定風量空調系統已經不能滿足相應的先進性要求,需要建立適時地個性化調節,尤其是在一些應用的場合中像是一些負荷變化大的建筑物、多區域控制的建筑物中,能夠充分滿足分區控制等要求的空調系統。而在這個領域中,變風量(VAV)空調系統無疑是這個領域內比較先進的一種樓宇中央空調系統,因其具有的舒適性、節能等特點,成為一個理想的選擇,也在人們的生活學習工作環境中日益普及者。因此,本文中為了分析研究變風量空調系統的運行特性,先根據研究內容和目的的需要,來分析空調系統各個環節特點,對變風量空調技術由淺至深的分析,了解到其有多變量、強耦合、非線性等這些特點,為之后的VAV空調系統建模做好鋪墊,之后再建立VAV空調系統主要部件的數學模型,并根據多變量控制系統各變量之間有耦合存在的特點, 利用模糊解耦的方法建立了相應的基礎數學模型,為提高變風量空調系統中室內溫度回路的控制精度和品質打下基礎。35031

Analysis and modeling of variable air volume air conditioning system
Abstract:With the high demand of people to the quality of life, so air conditioning has become an essential part of the. At the same time, the improvement of the quality and performance of the air conditioning system is also necessary. Because we are familiar with the traditional constant air volume air conditioning system has been unable to meet the corresponding advanced requirements, the need to establish timely inpidual regulation especially in some application occasions like some load changes in large buildings, multi zone control of buildings, can fully meet the zoning control requirements of the air conditioning system. And in this field, variable air volume (VAV air conditioning system )is undoubtedly the more advanced a central air-conditioning system in buildings, because of its comfort and energy-saving characteristics become an ideal choice, also in people's life learning environment becomes more and more popular. Therefore, this paper to analysis of variable air volume air conditioning system operating characteristics, first according to the content and purpose of the study to analyze each link the characteristics of air conditioning system, of variable air volume air conditioning technology from shallow to deep analysis.It is understood that the characteristics of the system is the basis for the modeling of VAV air conditioning system after the modeling of the VAV air conditioning system, and the mathematical model of the main parts of the air conditioning system is established.And according to the characteristics of the coupling between the multi-variable control system variables,the basic mathematical model is established by using the method of fuzzy decoupling.In order to improve the indoor temperature loop control precision and quality of the air conditioning system.
