【摘要】：当前,我国建筑规模逐年增大,建筑节能成为节能减排的最有效途径,集中空调能耗占建筑能耗的比例越来越重,因此降低建筑空调能耗能势在必行。传统空调系统存在能源损失及空气品质差的弊端,人们对空调系统的要求趋于更加节能以及能够提供更好的空气品质。地源热泵是一种利用绿色能源的空调技术,温湿度独立控制空调系统在节能及提高空气品质方面优势明显。将这两种空调技术结合,提出一种基于地源热泵的温湿度独立控制空调系统有利于空调节能技术的革新与发展,符合空调技术的发展趋势。温湿度独立控制系统是将温度、湿度分开控制的空调设计理念。温度控制系统的节能优势是利用高温冷源,夏季利用地源热泵的地埋管直供冷水作为温度控制系统的冷源,利用溶液除湿新风机组处理室内湿负荷;冬季利用地源热泵制热功能制取生活热水,从而解决土壤源的全年热平衡问题。对某医院综合楼建筑进行负荷分析,分开计算建筑热、湿负荷,确定应用基于地源热泵的温湿度独立控制空调系统的设计方案,提出温湿度空调的设计步骤及主要设备选型方案。本文通过对案例工程系统节能性进行理论分析,分别从冷源、空调末端、输配系统方面计算其能效比,得出温湿度系统的整体性能系数高于传统对联机空调系统。通过分析建筑物各设备承担负荷的能效情况,分析系统进一步节能潜力。模拟全年运行费用及初投资回报研究系统的经济效益,分析出同多联机空调系统比较,温湿度独立控制系统初投资高,运行成本低,在设计运行年限内经济效益可观。最后,根据工程应用情况,总结温湿度独立控制系统推广问题,提出推广建议。
[Abstract]:At present, the scale of building in our country increases year by year, building energy saving becomes the most effective way of energy saving and emission reduction, the proportion of energy consumption of centralized air conditioning to building energy consumption is more and more heavy, so it is imperative to reduce the energy consumption of building air conditioning. The traditional air conditioning system has the disadvantages of energy loss and poor air quality. The demand of air conditioning system tends to be more energy saving and can provide better air quality. Ground-source heat pump (GSHP) is a kind of air conditioning technology using green energy. The air conditioning system controlled independently by temperature and humidity has obvious advantages in saving energy and improving air quality. Combining these two air conditioning technologies, it is proposed that an independent temperature and humidity control system based on ground source heat pump is conducive to the innovation and development of air conditioning energy saving technology, which is in line with the development trend of air conditioning technology. The temperature and humidity independent control system is the air conditioning design idea which controls the temperature and humidity separately. The advantage of the temperature control system is to use the high temperature cold source, the ground source heat pump direct cold water supply in summer as the cold source of the temperature control system, and the solution dehumidification fresh air unit to deal with the indoor wet load. The heating function of ground source heat pump (GSHP) is used to make domestic hot water in winter, so as to solve the problem of annual heat balance of soil source. The load analysis of a hospital complex building is carried out, and the heat and humidity load of the building is calculated separately, and the design scheme of the air conditioning system with independent control of temperature and humidity based on ground-source heat pump is determined. The design steps of temperature and humidity air conditioning and the selection scheme of main equipment are put forward. In this paper, the energy efficiency ratio of cold source, air conditioning terminal, transmission and distribution system is calculated by theoretical analysis of case engineering system. It is concluded that the overall performance coefficient of temperature and humidity system is higher than that of traditional on-line air conditioning system. Based on the analysis of the energy efficiency of the equipment carrying the load, the potential of further energy saving of the system is analyzed. The paper simulates the economic benefit of the operating cost and the initial investment return research system of the whole year, and analyzes that the independent temperature and humidity control system has high initial investment, low operating cost and considerable economic benefit in the design operation life compared with the multiple on-line air conditioning system. Finally, according to the engineering application situation, summarizes the temperature and humidity independent control system popularizes the question, puts forward the popularizing suggestion.
