【摘要】：随着社会的不断发展，人们对建筑热环境的要求越来越高，，社会总能耗中建筑能耗的比重逐年增加，供暖、空调及通风的年能耗占建筑总能耗的40%～60%。暖通空调系统中的耗电量巨大，针对这一问题，通过对国内外建筑节能现状的研究和分析得出从下面三个方面来节能：第一，寻找可再生能源提高能源利用率，实现能源由高品位能源向低品位能源转变；第二，优化末端系统的设计和改革系统运行模式；第三，提高建筑物的储能特性。通过对温湿度独立控制空调系统发展现状的分析，提出了一种新型的能源塔热泵与地板辐射置换通风空调系统。地板辐射置换通风空调系统作为一种新型空调系统在节能和舒适性上广泛得到人们的认可，此空调系统与传统空调系统的最大差别在于室内温、湿度独立控制和辐射换热特性的不同，因此室内设计参数的选取，负荷的计算和分配、冷热源的选取、新风系统的设计等都有别于传统系统。地板辐射供暖技术已经广泛被应用，然而地板辐射供冷技术还不够完全成熟，需要解决地板结露问题、供冷能力有限问题，置换通风技术主要有待解决供冷能力问题。置换通风与地板辐射相结合的复合系统，既可以提高系统的供冷能力，还可以解决地板结露问题，给人们创造出一种温、湿度独立控制的热舒适环境。本文主要对能源塔热泵结合新型地板辐射置换通风空调系统的实际应用进行了研究。本文重点对工程的地板辐射系统和新风系统承担的冬、夏及过渡季节负荷进行了计算；对置换通风系统的设计与计算提拱了方法并对本工程的新风参数进行了选取；对能源塔热泵在过渡季节供热能力提供了计算方法并对此工程进行了供热能力计算；最后对地板辐射系统和置换通风系统的施工工艺和系统的运行调节进行了介绍。此项目样板间主卧的室内温度场和湿度场及室内送风口送风的温度场和速度场进行测试结果表明，地板辐射与置换通风空调系统在设计、施工和运行是合理的。通过计算得出能源塔热泵在夏季和过度季节能够作为地板辐射置换通风空调系统的冷热源。本文从技术上、经济上、环境效益和社会效益上证明了能源塔热泵与地板辐射置换通风空调系统的可行性。
[Abstract]:With the development of society, the demand of building thermal environment is more and more high. The proportion of building energy consumption increases year by year. The annual energy consumption of heating, air conditioning and ventilation accounts for 40% of the total building energy consumption. The energy consumption in HVAC system is huge. In view of this problem, through the research and analysis of the present situation of energy saving in buildings at home and abroad, it is concluded that energy conservation can be achieved from the following three aspects: first, to find renewable energy to improve energy utilization, Second, optimize the design of the terminal system and reform the operating mode of the system; third, improve the energy storage characteristics of buildings. A new type of energy tower heat pump and floor radiation displacement ventilation air conditioning system is proposed by analyzing the development of independent temperature and humidity control air conditioning system. As a new type of air conditioning system, floor radiation displacement ventilation air conditioning system has been widely recognized in energy saving and comfort. The biggest difference between this air conditioning system and traditional air conditioning system is indoor temperature. Because of the difference of humidity independent control and radiation heat transfer characteristics, the selection of indoor design parameters, the calculation and distribution of load, the selection of cold and heat sources, and the design of fresh air system are all different from the traditional systems. Floor radiant heating technology has been widely used, but the floor radiation cooling technology is not fully mature, need to solve the problem of floor condensation, cooling capacity is limited, displacement ventilation technology needs to solve the problem of cooling capacity. The combined system of displacement ventilation and floor radiation can not only improve the cooling ability of the system, but also solve the problem of floor condensation, and create a kind of thermal comfort environment with independent control of temperature and humidity. In this paper, the practical application of energy tower heat pump combined with new floor radiation displacement ventilation air conditioning system is studied. In this paper, the load of floor radiation system and fresh air system in winter, summer and transition season are calculated, the design and calculation of displacement ventilation system are raised, and the parameters of fresh air are selected. The heat supply capacity of energy tower heat pump in transition season is calculated and the heat supply capacity of this project is calculated. Finally, the construction technology and system operation regulation of floor radiation system and displacement ventilation system are introduced. The results show that the floor radiation and displacement ventilation air conditioning system is reasonable in design, construction and operation. The energy tower heat pump can be used as the heat and cold source of floor radiation displacement ventilation air conditioning system in summer and over season. This paper proves the feasibility of energy tower heat pump and floor radiation displacement ventilation and air conditioning system in terms of technology, economy, environmental benefit and social benefit.
