浅谈建筑环境与暖通空调能耗

浅谈建筑环境与暖通空调能耗暖通空调发展到今天,在满足人们众多功能要求的同时,不得不将考虑的范围扩展到建筑周围的生态环境。
能源的大量使用,对周围环境的无限破坏,这些都对人类发展产生了严重的影响。
如何建立一种生态的平衡,这需要我们暖通空调进行反思。
研究建筑环境,了解暖通空调负荷产生的原因及影响因素,可以更加合理地提出解决问题的方法。
1、建筑环境与暖通空调能耗概述(1)建筑与建筑生态环境之间的关系,本质应该是建筑去适应其生态环境,减少对环境的各种恶劣影响,而暖通空调系统此时便在建筑中发挥一种能动性的作用,利用各种方法创造良好的建筑生态环境,以此来协调建筑与环境之间的关系。
为了创造舒适的室内空调环境,必须消耗大量的能源。
暖通空调能耗是建筑能耗中的大户,由此可见建筑节能工作的重点应该是暖通空调的节能。
从暖通空调的能耗组成可以看出:暖通空调系统的能耗主要决定于空调冷、热负荷的确定和空调系统的合理配置,空调系统的布置和空调设备的选择是以空调负荷为依据的。
所以暖通空调节能的关键是空调外界负荷和内部负荷的确定,而暖通空调节能工作也应该从这个方面着手,合理布置建筑物的位置,正确选择外墙、门、窗、屋顶的形状及材料等,尽量减少空调负荷。
暖通空调的目标是为人们提供舒适的生活和生产室内热环境,在一般的舒适性空调中,以能够使人体保持平衡而满足人们的舒适感觉为目的;在恒温恒湿或有洁净要求的工艺性空调中,一切以满足生产工艺为目标。
而房屋的建筑热工设计是恰当地利用房屋维护结构的热导性,抵抗室外气候的变化,使房间内产生舒适的微气候。
(2)围护结构包括外围结构和内围护结构。
外围护结构主要包括屋面、外墙和窗户;内围护结构主要包括地面、顶棚、内隔墙等。
在采暖建筑中,围护结构的传热热损失占总的热损失的比例是较大的,在北京地区,通过围护结构的传热热损失约占全部热损失的77%;通过门窗缝隙的空气渗透热损失约占23%;在哈尔滨地区,通过围护结构的传热热损失约占全部热损失的71%;通过门窗缝隙的空气渗透热损失约占29%。

外文翻译ANALYSIS OF HVAC SYSTEM ENERGYCONSERVATIONIN BUILDINGSABSTRACTE conomic development and people's increasing demand for energy, but the nature of the energy is not inexhaustible. Environment and energy issues become increasingly acute, if no measures are taken, then the energy will limit the rapid economic development of the question.With the improvement of living standard, building energy consumption in the proportion of total energy consumption is increasing. In developed countries, building energy consumption accounts for 40% of total energy consumption of the community, while the country despite the low level of socio-economic development, but the building energy consumption has nearly 30% of total energy consumption, and still rising. Therefore, in western countries or in China, building energy consumption is affecting the socio-economic status of the overall development of the question. In building energy consumption, the energy consumption for HVAC systems has accounted for 30% of building energy consumption -50%, with the extensive application of HVAC, energy consumption for HVAC systems will further increase Great. HVAC systems are often coupled with high-quality electric energy, and our power and relatively tight in some areas, lack of energy supply and demand which is bound to lead to further intensification of contradictions. Therefore, energy-saving heating, higher professional requirements is inevitable across the board.KEYWORDS:energy-saving,HVAC1. Energy saving design measures should be takenRapid changes in science and technology today, area HVAC new technologies emerge, we can achieve a variety of ways of energy saving HVAC systems.1.1 Starting from the design, selecting, designing HVAC systems, so that the efficient state of the economy running.Design is a leading engineering, system design will directly affect its performance. The building load calculation is an important part of the design, a common problem is that the current design of short duration, many designers to save time, wrong use of the design manual for the design or preliminary design estimates of cold, heat load with the unit construction area of cold, heat load index, direct construction design stage as hot and cold load to determine the basis, often making the total load is too large, resulting in heating equipment, air conditioning is too large, higher initial investment, operating costs, increased energy consumption.1.2 using the new energy-saving air-conditioning and heating comfort and healthy mannerAffect human thermal comfort environment of many parameters, different environmental parameters can get the same effect of thermal comfort, but for different heat and moisture parameters of the environment of its energy consumption air conditioning system is not the same.1.3 Actual situation of a reasonable choice of cold and heat sources, seek to achieve diversification of cold and heat sourceWith the extensive application of HVAC systems on non-renewable energy consumption also rose sharply, while the broken part of the ecological environment are becoming increasingly intensified. How to choose a reasonable heating sources, has caused widespread concern of all parties.1.4 to enhance the use of hot and cold recycling of the work, to achieve maximum energyHVAC systems to improve energy efficiency is one of the ways to achieve energy-saving air-conditioning. Heat recovery system installed mainly through energy recovery, with the air from wind energy to deal with new, fresh air can reducethe energy required for processing, reducing the load, to save energy. In the choice of heat recovery, the should be integrated with the local climate Tiao Jian, Jing Ji situation, Gong Cheng actual situation of harmful exhaust gases of the situation in a variety of factors Deng integrated to determine the Xuanyong suitable heat recovery, so as to achieve Hua Jiao Shao's investment, recovery of more heat (cold) the amount of purpose.1.5 focus on development of renewable energy, and actively promoting new energyAs the air-conditioning systems used in high-grade, non-renewable energy resources and environmental problems caused by the increasingly prominent, have to develop some reasonable and effective renewable energy to ease the current tensions. To heat (cold) and solar and other renewable resources used in air conditioning and refrigeration, has certain advantages, but also clean and pollution-free. Ground Source Heat Pump is a use of shallow and deep earth energy, including soil, groundwater, surface water, seawater, sewage, etc. as a cold source in winter and summer heat is not only heating but also a new central air-conditioning system cooling.2. Saving design problemsAchieve energy-saving HVAC systems, now has a lot of mature conditions, but in practical applications there are some problems:2.1 The issue of public awareness of energy conservationThe past is not enough public understanding of energy, and on the air conditioning is also very one-sided view. For a comfort of air conditioning system or heating system, should the human body has a very good comfort. But the prevailing view now is: the colder the better air-conditioning, heating the more heat the better. This is obviously we seek the comfort of air conditioning is contrary to the view. In fact, this not only greatly increase the energy consumption of air conditioning heating, indoor and outdoor temperature and because of the increase, but also to the human body's adaptability to different environmental decline, lowering the body immunity. Therefore, we need to improve advocacy efforts to change public to the traditional understanding of air conditioning and heating, vigorous publicity andpromotion in accordance with building standards and the cold heat energy metering devices to collect tolls, raise public consciousness of energy.2.2 The design concept of the problemReasonable energy-saving design is a prerequisite. At present, some designers due to inadequate attention to design empirical value when applied blindly, resulting in the increase of the initial investment, energy consumption surprising, therefore recommended that the government functions and the energy-saving review body, to increase the monitoring of the HVAC air-conditioning energy saving efforts enhance staff awareness of energy conservation design, so that energy conservation is implemented.2.3 The promotion of new technologies issueNew technology in the HVAC system for energy conservation provides a new direction. Such as ground source heat pump systems, solar cooling and heating system, not only to achieve efficient use of renewable energy, and can bring significant economic benefits, is worth promoting. However, as with any new technology, these new technologies are often high in cost, and the geographical conditions of use have certain limitations, and technically there are still many areas for improvement to improve. Therefore, new energy-efficient technologies, we should be according to local conditions, sum up experience, and actively promote.3. ConclusionHVAC systems saving energy in the building occupies a very important position, should attract enough attention to the designer. Designers should be from a design point of view fully into account the high and strict compliance with energy standards energy saving ideas to run through all aspects of the construction sector. Energy-saving technologies and renewable energy recycling, the Government and other relevant departments should support and vigorously promoted. And the design, construction, supervision, quality supervision, municipal administration and other departments should cooperate closely and pay close attention to implementing a cold, heat metering devices to collect tolls, so people really get benefit from energy efficient building, energy-saving construction and non-heating energy efficientbuilding can not have the same charge standard. At the same time to raise public awareness of energy conservation, and vigorously promote the development of new energy-saving technologies to achieve sustainable development of society.References[1] "residential design standard" DBJ14-037-2006.[2] "Public Buildings Energy Efficiency Design Standards" DBJ14-036-2006.[3] "Technical Specification for radiant heating" JGJ142-2004.析暖通空调系统在建筑中的节能问题摘要经济的发展使人们对能源的需求不断增加,但是自然界的能源并不是取之不尽,用之不竭的。

关键词:建筑环境暖通空调能耗浅谈建筑环境与暖通空调能耗能源为经济的发展提供了动力,但是由于各种原因,能源的发展往往滞后于经济的发展。
近几年,中国的国民生产总值的增长率维持在约10%,但是能源的增长率只有3%~4%。
这样的形势要求我们必须节能。
建筑能源消耗在社会总能耗中的比例较大,发达国家的建筑用能一般占到全国总能耗的30%~40%;中国采暖区的城镇人口虽然只占全国人口的13.6%,但是采暖用能却占全国总能耗的9.6%。
建筑节能是建筑发展的基本趋势,也是当代建筑科学技术的一个新的生长点。
现代建筑的必要组成部分暖通空调领域也已经收到这种趋势的影响,暖通空调系统中的节能正在引起暖通空调工作者的注意,并且针对不同的国家、地区的能源特点和不同建筑的采暖、通风、空调要求发展者相关的节能技术。
研究建筑环境,了解暖通空调负荷产生的原因及影响因素,可以更加合理地提出解决问题的方法。
暖通空调能耗的组成为了创造舒适的室内空调环境,必须消耗大量的能源。
暖通空调能耗是建筑能耗中的大户,居统计在发达国家中暖通空调能耗占建筑能耗的65%,以建筑能耗占总能耗的356%计算,暖通空调能耗占总能耗的比例竟高达22.75%,由此可见建筑节能工作的重点应该是暖通空调的节能。
从暖通空调的能耗组成可以看出:暖通空调系统的能耗主要决定于空调冷、热负荷的确定和空调系统的合理配置,空调系统的布置和空调设备的选择是以空调负荷为依据的。
所以暖通空调节能的关键是空调外界负荷和内部负荷的确定,而暖通空调节能工作也应该从这个方面着手,合理布置建筑物的位置,正确选择外墙、门、窗、屋顶的形状及材料等,尽量减少空调负荷。
室内环境的影响暖通空调的目标是为人们提供舒适的生活和生产室内热环境,主要包括:室内空气温度、空气湿度、气流速度以及人体与周围环境(包括四壁、地面、顶棚等)之间的辐射换热(简称环境热辐射)等。
在一般的舒适性空调中,以能够使人体保持平衡而满足人们的舒适感觉为目的;在恒温恒湿或有洁净要求的工艺性空调中,一切以满足生产工艺为目标。
而房屋的建筑热工设计是恰当地利用房屋维护结构的热导性,抵抗室外气候的变化,使房间内产生舒适的微气候。
围护结构暖通空调负荷的影响围护结构包括外围结构和内围护结构。
外围护结构主要包括屋面、外墙和窗户(包括阳台门等);内围护结构主要包括地面、顶棚、内隔墙等。
在采暖建筑中,围护结构的传热热损失占总的热损失的比例是较大的,以4个单元6层的砖墙、混凝土楼板的典型多层建筑为例,在北京地区,通过围护结构的传热热损失约占全部热损失的77%(其中外墙25%,窗户24%,楼梯间隔墙11%,屋面9%,阳台门下部3%,地面2%);通过门窗缝隙的空气渗透热损失约占23%;在哈尔滨地区,通过围护结构的传热热损失约占全部热损失的71%(其中外墙28%,窗户28%,屋面9%,阳台门下部1%,外门1%,地面4%);通过门窗缝隙的空气渗透热损失约占29%。
由此可见改善围护结构的热工性能对于暖通空调节能具有重要意义。
建筑规划设计对暖通空调节能的影响规划设计时建筑节能设计的重要方面,规划节能设计应从建设选址、分区、建筑和道路布局走向、建筑方位朝向、建筑体型、建筑间距、冬季季风主导方向、太阳辐射、建筑外部空间环境构成等方面进行研究。
以优化建筑的微气候环境;有利于节能,充分重视和利用太阳能、冬季主导风向、地形和地貌,利用自然因素。
节能规划设计就是分析成气候的决定因素、辐射因素、大气环流因素和地理因素的有利、不利影响,通过建筑的规划布局对上述因素进行充分利用、改造,形成良好的居住条件和有利于节能的微气候环境。
建筑旁边的绿化不但有防风、隔声、防尘和美化环境的作用,而且对于建筑节能也有重要作用。
因为首先树木可以从根部吸收水分,同过叶面蒸发,从而降低空气温度,其次树木有很好的遮阳作用,从而使建筑物直接受到的太阳辐射及从地面得到的辐射热减少,二是树木有引导风及挡风的作用。
此外,地面不但会反射太阳辐射,而且其本身辐射升高后又会成为新的热辐射源。
所以尽量种草、植树,避免地面土壤裸露,并减少不必要的大面积混凝土地坪对于减少空调负荷,达到节能的目的是非常重要的手段。
而且清洁的室外环境对于洁净空调系统的有效运行和空调箱过滤器的寿命也是有利的。
总之,建筑环境是影响暖通空调能耗的重要因素,从建筑环境着手考虑是解决暖通空调节能问题的关键,也是一种积极的节能工作作者认为应着重以下方面的工作:(1)制定相应的政策法规。
制定政策法规对建筑节能工作具有指导意义,而且以法规的形式出现,一则表示政府重视和鼓励,二则可以为节能工作的开展提供法律依据。
近年来国务院和有关部委也颁布了相关的建筑节能法规;此外各地方政府也根据气候条件和能源特点,制定了各自的建筑节能标准和规定;但是总的来说法规和政策还有待进一步的完善。
(2)推动科技的进步。
暖通空调节能工作的顺利开展离不开技术的进步。
国家在制定节能政策时,即指明了发展方向,同时也鼓励了技术进步。
只有依靠科技的发展,不断优化能源结构和用能方式,才能够真正做到节能,创造巨大的社会效益和经济效益。
(3)加强专业间的协调。
建筑是各工种配合的产物,建筑专业在考虑建筑环境时,不但要从建筑功能、建筑美学等方面考虑,还要与设备工种进行配合,充分重视建筑环境、建筑材料等对暖通空调乃至建筑能耗的影响,各工种协调工作,共同完成节能设计。
总之从建筑内外环境着手,不断优化建筑热功能,充分利用有利的建筑环境,必然会创造出适宜的室内热环境,同时也必将有利于暖通空调节能的发展。
