【摘要】：伴隨著我國(guó)工業(yè)化的步步深入和城市化的高速發(fā)展,不可再生能源的需求量持續(xù)攀升、有增無(wú)減。人民生活水平的不斷提高也伴隨著大量化石能源消耗,同時(shí),溫室氣體、有害氣體以及細(xì)顆粒物(PM2.5)的排放量也在不斷增大。當(dāng)排放量超過(guò)大氣循環(huán)能力和承載度時(shí),便很有可能導(dǎo)致大范圍霧霾天氣的形成。霧霾不僅給人民生活和交通帶來(lái)不便,還會(huì)威脅人體呼吸系統(tǒng)甚至是心血管系統(tǒng)的健康。因此為了改善空氣質(zhì)量、節(jié)約煤炭資源、減輕生態(tài)環(huán)境的負(fù)擔(dān),可再生清潔能源的開(kāi)發(fā)利用已是迫在眉睫、勢(shì)在必行。本研究將地下水資源作為冷熱源對(duì)煤礦的工作區(qū)和住宅區(qū)進(jìn)行制冷和供暖,并借助集散控制技術(shù)實(shí)現(xiàn)對(duì)中央空調(diào)系統(tǒng)的自動(dòng)調(diào)節(jié),結(jié)合舒適性、環(huán)保性、實(shí)用性于一體。不僅代替了傳統(tǒng)燃煤采暖設(shè)備,而且進(jìn)一步減少了制冷和供暖過(guò)程中的電量消耗,節(jié)約能源的同時(shí)有效地減少了設(shè)備的數(shù)量及占地面積。 本文從地下水源熱泵技術(shù)的結(jié)構(gòu)特點(diǎn)和工作流程出發(fā),分析了地理?xiàng)l件對(duì)地下水源熱泵系統(tǒng)性能的影響,描述了中央空調(diào)系統(tǒng)的變頻控制的基本思路,繼而從硬件、PID控制算法和軟件三個(gè)角度概括敘述了中央空調(diào)集散控制系統(tǒng),并在詳細(xì)介紹系統(tǒng)的硬件設(shè)計(jì)的同時(shí),著重介紹了系統(tǒng)的上位機(jī)軟件設(shè)計(jì)以及下位機(jī)中所運(yùn)用的帶死區(qū)增量型數(shù)字PID控制算法。本系統(tǒng)將水源熱泵與集散控制技術(shù)有機(jī)結(jié)合在一起,對(duì)于節(jié)能環(huán)保有著極其重要的意義,并且有極為寬廣的應(yīng)用前景。
[Abstract]:With the deepening of industrialization and the rapid development of urbanization, the demand for non-renewable energy is increasing. Rising living standards are accompanied by a large amount of fossil energy consumption, as well as emissions of greenhouse gases, harmful gases and fine particulate matter (PM2.5). When emissions exceed atmospheric cycling capacity and carrying capacity, it is likely to lead to the formation of a wide range of haze weather. Haze not only brings inconvenience to people's life and transportation, but also threatens the health of human respiratory system and even cardiovascular system. Therefore, in order to improve air quality, save coal resources and lighten the burden of ecological environment, the development and utilization of renewable clean energy is urgent and imperative. In this study, groundwater is used as a source of cold and heat to refrigerate and heat the work area and residential area of coal mine, and the automatic adjustment of central air conditioning system is realized by means of distributed control technology, which combines comfort, environmental protection and practicability. It not only replaces the traditional coal-fired heating equipment, but also reduces the consumption of electricity in the process of refrigeration and heating. Based on the structural characteristics and work flow of groundwater source heat pump technology, this paper analyzes the influence of geographical conditions on the performance of underground water source heat pump system, and describes the basic idea of frequency conversion control of central air conditioning system. Then, from three aspects of hardware pid control algorithm and software, the central air conditioning distributed control system is described, and the hardware design of the system is introduced in detail. The software design of the upper computer and the incremental digital PID control algorithm with dead zone used in the lower computer are introduced emphatically. The system combines water source heat pump with distributed control technology, which is of great significance for energy saving and environmental protection, and has a wide application prospect.
