热泵技术在建筑领域的运用 摘要：据统计，目前我国建筑能耗约占国民经济总能耗的25%左右，且呈上升趋势。另一方面，随着建筑能耗的增加和大量空调设备的安装，“城市热岛效应”日益严重，使环境日益恶化。我国建筑节能的重点应为：建筑本体的节能、采暖系统节能、提高照明和其他电器的效率、大型公共建筑节能。随着科学技术的日新月异，能源短缺已不容忽视，节约能源已受到世界性的普遍关注，在我国亦不例外。目前，全世界有近30%的能源消耗在建筑物上，长此以往，将严重影响世界经济的可持续发展。因此，能源问题将成为本世纪的热门话题。本文着重讲的是现有建筑节能存在的问题、解决方法与未来的发展方向。 ? In recent years, with the people-oriented design concept of the proposed residential comfort people have become increasingly demanding, building energy consumption also will increase. According to statistics, Chinas national economy, building energy consumption accounts for about 25% of the total energy consumption, and on the rise .On the other hand, with the increase in building energy consumption and large air-conditioning installation, urban heat island effect is worsening, deteriorating the environment. Chinas building energy efficiency should focus on are: ontology building energy-saving, energy-saving heating system, improve the efficiency of lighting and other electrical appliances, large public building energy efficiency. With the ever-changing science and technology, energy shortage has not be ignored, a worldwide energy conservation has been widespread concern in China is no exception. At present, nearly 30% of the worlds energy consumption in buildings, the long run, it will seriously affect the world economy and sustainable development. Therefore, the energy issue will become a hot topic in this century. This article focuses on talking about the existing building energy problems, solutions and future direction of development. ? 建筑节能是一项综合的大型的系统工程，涉及国家的能源政策，也涉及到建筑、结构、建筑热工、建筑设备、建筑电气、技术经济、计算机软件等专业的技术、资料、经验。但是就目前已建成的节能建筑物来看，窗户过于小，又不能开启，恐怕还不符合一般人的生活习惯，而且在建筑本身的节能上考虑较多，而其中的空调系统，采用高效节能的主机和合理的系统设计，建筑内部的热回收的考虑，尚嫌不足。下面仅就空调、采暖、热水供应两个节能的重大课题，作一介绍。 热泵技术是一种热能回收技术。使用热泵技术，利用空气、水或土壤中所蕴藏的趋于无限的能量，一年四季都可以取出其中的热量来制造热水；或者将热量排放到空气、水、土壤中。利用热泵原理制造的空调冷热水机组或者热泵热水机组都是一种制冷供热效率都大于1的设备。无论是水源热泵或者空气源热泵，都是可以吸取低温水源或空气源的热量，再将这一些热量连同本身所消耗的一部分电能所转化的热量，转送到常温环境条件下去应用。利用热泵技术，可以充分利用空调的余热，制造出空调和生活热水同时产生的“两用机组”，或者称
