【摘要】：傳統(tǒng)室內(nèi)環(huán)境營造方法主要針對單一的參數(shù)需求，營造近似均勻的參數(shù)環(huán)境。但實(shí)際中，同一空間中不同位置或區(qū)域可能同時(shí)存在有差異的參數(shù)需求，面向該類需求在各位置或區(qū)域間營造有差異的參數(shù)環(huán)境，即非均勻環(huán)境，將能切實(shí)提高需求保障水平。另一方面，隨著建筑業(yè)的發(fā)展，用于室內(nèi)環(huán)境營造的暖通空調(diào)能耗日益增高，因此，面向?qū)嶋H需求營造節(jié)能高效的非均勻環(huán)境意義重大。而對非均勻環(huán)境營造關(guān)鍵問題的研究，具有重要的學(xué)術(shù)意義和工程應(yīng)用價(jià)值。 論文圍繞面向非均勻需求的室內(nèi)環(huán)境營造關(guān)鍵問題進(jìn)行了研究，包括：任意初始條件影響的快速預(yù)測方法、恒定源辨識(shí)方法、氣流組織非均勻營造潛力評價(jià)方法和面向需求的送風(fēng)參數(shù)優(yōu)化調(diào)節(jié)方法，并且對非均勻環(huán)境的實(shí)現(xiàn)方法進(jìn)行了探討。主要?jiǎng)?chuàng)新性工作如下： （1）建立了基于分區(qū)思想和分初始條件可及度的任意初始條件影響快速預(yù)測方法，通過理論推導(dǎo)和數(shù)值驗(yàn)證，證明了方法的正確性。對不同區(qū)域劃分?jǐn)?shù)目下預(yù)測方法的精度進(jìn)行了研究。利用送風(fēng)可及度、污染源可及度和分初始條件可及度概念，建立了適應(yīng)任意特征初始條件的室內(nèi)任意位置瞬態(tài)濃度分布表達(dá)式；（2）對多源同時(shí)釋放的源辨識(shí)方法進(jìn)行了實(shí)驗(yàn)研究，對方法的可行性進(jìn)行了驗(yàn)證，對不同因素對辨識(shí)結(jié)果的影響進(jìn)行了分析。進(jìn)一步開展了非同時(shí)釋放的源辨識(shí)方法研究，，建立了兩類典型的源非同時(shí)釋放場景的辨識(shí)方法，并對方法進(jìn)行了數(shù)值驗(yàn)證；（3）提出了評價(jià)不同氣流組織在室內(nèi)任意兩位置或區(qū)域間營造參數(shù)差異潛力的送風(fēng)差異度指標(biāo)，利用該指標(biāo)對不同氣流組織下的非均勻營造潛力進(jìn)行了分析，并將該指標(biāo)在評價(jià)一項(xiàng)實(shí)際在建工程的空調(diào)個(gè)性化溫度調(diào)控能力方面進(jìn)行了應(yīng)用；（4）建立了滿足多位置不同參數(shù)需求的送風(fēng)參數(shù)優(yōu)化模型，通過算例展示了模型的可靠性。針對保障位置參數(shù)調(diào)節(jié)到位之前需求參數(shù)或源參數(shù)突然發(fā)生改變的情況，建立了響應(yīng)改變的送風(fēng)優(yōu)化調(diào)節(jié)方法。建立了保障位置參數(shù)偏離設(shè)定值時(shí)的參數(shù)快速調(diào)控策略；（5）基于論文的研究成果，對面向需求的室內(nèi)非均勻環(huán)境的實(shí)現(xiàn)方法進(jìn)行了探討，提出了多模通風(fēng)的設(shè)計(jì)與控制思路。通過不同算例的分析，對現(xiàn)有通風(fēng)系統(tǒng)下的非均勻參數(shù)營造過程以及多模通風(fēng)系統(tǒng)的設(shè)計(jì)與送風(fēng)調(diào)控進(jìn)行了展示。 論文研究成果將在參數(shù)分布規(guī)律、源參數(shù)獲取、系統(tǒng)設(shè)計(jì)和參數(shù)控制方面為室內(nèi)非均勻環(huán)境營造提供理論支撐。
[Abstract]:The traditional indoor environment construction method mainly aims at the single parameter demand, creates the approximate uniform parameter environment. However, in practice, different locations or regions in the same space may have different parameter requirements at the same time. In order to meet these requirements, different parametric environments, i.e. non-uniform environments, can effectively improve the level of demand guarantee. On the other hand, with the development of the construction industry, the energy consumption of HVAC used in indoor environment is increasing day by day. Therefore, it is of great significance to create an energy-efficient and non-uniform environment to meet the actual demand. The research on the key problems of non-uniform environment construction has important academic significance and engineering application value. In this paper, the key problems of indoor environment construction for non-uniform demand are studied, including: fast prediction method of arbitrary initial condition effect, constant source identification method. The evaluation method of non-uniform construction potential of airflow organization and the optimal adjustment method of air supply parameters for demand are discussed, and the realization method of non-uniform environment is also discussed. The main innovative work is as follows: (1) A fast prediction method for the influence of arbitrary initial conditions is established based on the idea of partition and the accessibility of sub-initial conditions. The correctness of the method is proved by theoretical derivation and numerical verification. The accuracy of the prediction method under different number of regions is studied. Using the concepts of air supply accessibility, pollution source accessibility and sub initial condition accessibility, an indoor transient concentration distribution expression for arbitrary characteristic initial conditions is established. The source identification method for simultaneous release of multiple sources is studied experimentally. The feasibility of the method is verified and the influence of different factors on the identification results is analyzed. In this paper, the identification method of non-simultaneous release source is further studied, and two typical identification methods of source non-simultaneous release scene are established. Numerical verification of the method is also carried out. An index of air supply difference degree is proposed to evaluate the potential of different airflow organizations to create parameter difference between any two positions or regions in the room. The potential of non-uniform construction under different airflow was analyzed by using this index. This index is applied to evaluate the individual temperature control ability of an actual project under construction. An optimized model of air supply parameters is established to meet the needs of multi-position and different parameters. The reliability of the model is demonstrated by an example. In view of the sudden change of requirement parameters or source parameters before the adjustment of guaranteed position parameters in place, a method of air supply optimization adjustment was established to respond to the change of position parameters. Based on the research results of the paper, the realization method of demand-oriented indoor non-uniform environment is discussed, and the design and control ideas of multi-mold ventilation are put forward. Through the analysis of different examples, the construction process of non-uniform parameters under the existing ventilation system and the design and control of the multi-model ventilation system are demonstrated. The research results of this paper will provide theoretical support for the building of indoor non-uniform environment in the aspects of parameter distribution law, source parameter acquisition, system design and parameter control.
