body material 是什么意思
暖通空调(Heating, Ventilation and Air Conditioning,简称HVAC)是指室内或车内负责暖气、通风及空气调节的系统或相关设备。暖通空调系统的设计应用到热力学、流体力学及流体机械,是机械工程领域中的重要分支学科。
有时也在缩写HVAC中加入R,代表冷冻(Refrigeration),缩写就变成HVAC&R或HVACR,或是缩写中加入R,减去代表通风的V,缩写就变成HACR。
暖通空调系统可以控制空气的温度及湿度,提高室内的舒适度,是中大型工业建筑或办公建筑(如摩天楼)中重要的一环。
背景
暖气、通风及空气调节是由于许多科学家的发明及发现而产生,其中包括尼古拉·利沃夫(英语:Nikolay Lvov)、麦可·法拉第、威利斯·开利、鲁本·特灵(英语:Reuben Trane)、詹姆斯·焦耳、威廉·朗肯(英语:William Rankine)及萨迪·卡诺等人。
暖通空调系统的零件大约发明在工业革命前后,全世界的公司和发明家也不断引进各种现代化及高效率的新方法。暖通空调的三个主要功能暖气、通风及空气调节都有相互关联,其目的是在合理的安装、运转及维修成本下,提供舒适温度(英语:Thermal comfort)及适当的室内空气品质(英语:Indoor air quality)。暖通空调系统提供通风功能,减少空气渗透(英语:Infiltration (HVAC)),维持室内外或不同房间之间的压力关系, 空气流进或流出房间的特性称作室内空气分布(英语:Room air distribution)。
在现代的建筑中,上述机能(包括其控制系统,及系统的设计及安装)会整合在一个或多个的暖通空调系统中。针对小型的建筑,承包商会直接依需求选择暖通空调系统及设备。若是大型的建筑,会由建筑设计者及机械、结构等工程师共同分析、设计并选定暖通空调系统,再由专业的机械承包商来安装。
暖通空调系统是一个国际性的产业,其相关工作包括系统的运行、保养、设计及架构、设备制造商及业务、研究以及教育推广。暖通空调产业以往是由暖通空调设备的制造商所管理,现在有许多国际性管理及标准化组织关注此领域,包括国际暖通空调分销商管理办法委员会(英语:HARDI)、美国暖、制冷和空调工程师协会(英语:ASHRAE)、美国金属片与空调承包商协会(英语:SMACNA)、美国空调承包商协会(英语:Air Conditioning Contractors of America)、统一机械规范(Uniform Mechanical Code)、国际建筑法规(英语:International Building Code)于提供暖通空调产业相关服务并提升其水平。
特点和原理
暖通空调是分户的中央空调,中央空调它最大特点,是能够创造一种舒适的室内环境。而家居一般的分体的空调,它只能解决冷暖问题,而解决不了空气处理过程。现在,有了暖通空调就不一样了。
其空气处理过程有以下步骤:首先是空气进来以后,除了引进新风以外,可以把空气进行冷却处理,然后就进行过滤处理,过滤处理以后,增加了几大特点:第一就增加电子除尘器.,它主要可以捕捉非常小的颗粒的灰尘,一般来讲它可以捕捉一个微米的灰尘,而这个灰尘的范围内大部分都是细菌、、烟尘,或者是异味这样就都可以过滤掉;另外就是会增加一种加湿设备,这个加湿器可以创造我们房间的加湿达到40%左右的相对湿度,这样人会感到很舒适关于暖通
“暖通”是建筑设计中工种的一个分类的名称。
在我国的建筑行业,一直以“建筑设计院”牵头。一个建筑项目确立之后,首先由某个建筑设计院进行总体设计。
建筑的总体设计包括许多分项,一般如下:建筑设计,结构设计,基础设计,电力(强、弱电)设计,给排水设计,暖通设计,配套园林绿化景观设计等等。
暖通设计(如果该项目需要)是指该项目中的所需要的“空气调节系统”简称“空调系统”。一般“空调系统”包括制冷供暖系统,新风系统,排风(排油烟)系统等的综合设计。
所以说“暖通”从功能上说是建筑的一个组成部分。从建筑设计来说,他是建筑设计的一个分项。并不是单指“空调”。
需要说明的一点是:“空调”在一个建筑中可能是“中央空调系统”,也可能是“中央空调与独立空调的混合系统”,也可能全部是“独立空调的系统”。一切根据建筑的功能以及投资者的意向和实际需要而定。
暖通空调是一个很广的学科,应该全面的了解行业的有标准,可进入《暖通空调标准与质检》下载,希望对你更全面的了解有帮助。
演化过程
暖通空调系统最根本的目标是实现对环境温度的调控,以满足人们对环境舒适度以及一些工艺性的要求。
在早期的暖通空调系统中,一般用定流量水力系统,通过对末端设备风量的分档控制来实现对目标区域环境温度的调节,如用三速开关调节风机盘管风量以及通过变风量空调箱进行风量调节等。这种调节是简单、粗略以及分散式的,且在系统初调试合格后不需再对水力系统进行调节。
随着人们对环境舒适度的要求以及节能意识的不断提高,这种调节已经不能满足要求。于是人们开始用变流量水力系统以及变风量系统,通过电动调节阀或风阀执行器对系统的水量或风量进行连续调节来实现对环境温度的精确控制。
电动调节阀既可以通过与各种传感器、变送器以及控制器相连组成分散式的控制系统,也可以与楼宇控制系统相连组成分散控制、集中管理的中央控制系统,从而大大地提高了系统对环境温度调控的能力。
但是在一些系统负荷波动较大的变流量系统中,由于多台电动调节阀同时工作,任何一台电动调节阀工作状态的改变都会对其它的电动调节阀产生影响,而电动调节阀本身的抗干扰能力又比较差,从而造成了整个系统不稳定,对环境温度的调控能力下降,调节精度降低。
因此在目前的一些大型变流量中央空调水系统中,一种具有较强抗干扰能力的新型调节阀—动态平衡电动阀得到越来越广泛的应用。
同时,一种全新的全面平衡水力系统,也因其高效、稳定和节能而被越来越多的大型变流量水系统所用。[2]

省电技巧
1、选择适宜的出风角度
空气温度变低后,冷气流容易往下走,制冷时出风口向上,这样的制冷效果好。而在冬天时,热气都是往上走,制热时出风口应该向下,这样也能达到节能的效果。
2、设定适当的温度
制冷时,把室温调到26-27度,其冷负荷可以减少8%以上。人在睡眠时,代谢量减少30-50%,可将空调设于睡眠开关档,设置温度高2度,可节电20%;冬季制热,温度设置低2度,也可节电10%。

1 Summary
1.1 INTRODUCTION
With the constant development of China's economy, a high degree of information-based society, the new high-tech technology lied to all aspects of making intelligent has become a development trend. Tend to be intelligent automation system equipment from the start. In this paper, we present for the graduation project "intelligent small central air-conditioning," explained PLC control of Intelligent Design and central air-conditioning (Freezing Point) systems.
1.2 system and process Introduction
Is introduced as follows: We he this in the design, there are two central air-conditioning system, cooling water pump from the Big Three, three chilled water pump, a cooling tower fan, two chiller comprising two sets of major equipment such as refrigeration system (due to system Small, large power cooling towers, laboratories, etc., the system of the usual two sets of refrigeration system different from the two chiller only choose a cooling tower, roved by the calculation, this does not affect their performance) is one chiller Complete sets of equipment manufacturing plant supply. According to this design laboratory requirements, we selected the five full-2 * closed compressor chiller. It is based on general principles and laws of the air-conditioning, such as automatic control by the microprocessor. Chiller from the compressor, condenser and evaporator components. Compression of the refrigerant compressors, compressed into the refrigerator condenser, cooling water cooling, a liquid, precipitation heat away from the cooling water and cooling Tarja discharged into the atmosphere. Liquid refrigerant from the condenser into the evaporator evaporation absorb heat, chilled water cooling and chilled water fan coil absorbed into the cold air in the heat. This cycle of it, to bring out the indoor heat to reach the objective of reducing the ambient temperature. Therefore, the central air-conditioning refrigeration system for process control requirements:
(1) for the measurement of chilled water flow and return water temperature, thus calculate the actual air-conditioning cooling load, according to the actual cooling load chiller to determine the number of Taiwan Open, the best energy-sing status.
(2) the procedures for equipment linked: Start: cooling tower fan - cooling water pump - chilled water pumps - chiller. Stop: chiller - chilled water pumps - cooling water pump - the cooling tower fan. When one of the cooling water pump / chilled water pump failure, the backup cooling water pump / chilled water pump will automatically enter the workforce.
(3) measurement system for chilled water pipes to the pressure △ P = P1-P2 control of their bypass valve (TV) openings, to maintain the pressure.
(4) because we designed this lab aims to give students a more vivid image of the study and understanding of central air-conditioning system, so the design process, we will take into account the ropriate and important position to facilitate the installation of observation refrigeration Agent or the peep-flow situation.
1.3 PLC theory and lication
Central air-conditioning refrigeration system control are three kinds of control: the early relay control systems, direct digital controller DDC and the PLC (PLC) control system. Relay control system because of the high failure rate, the system complicated, the obvious shortcomings of higher power has been gradually eliminated by the people, direct digital controller DDC Although there he been very intelligent in the development. However, due to DDC its own anti-jamming capability and step-by-step grade structure and the limitations of limiting the scope of its lication. On the contrary, PLC control system with its reliable operation, use and maintenance are very convenient and anti-interference capability and high-speed network for the new structure of these significant advantages to gradually wide range of lications.
PLC is a computer in a family. In the last century after the invention of being, in machine tools, various lines of transportation machinery, power generation, chemical, and electronics industries of electrical control equipment has been widely used, early PLC, known as Programmable logic controller (Programmable Logic Controller), that is referred to as the PLC.
PLC is a powerful, reliable, easy maintenance, and so many advantages. The traditional relay circuit, it is difficult to achieve complex logic functions and the digital control, but also to achieve a certain amount of logic control not only the design cumbersome and difficult to upgrade and prone to failure, maintenance complex, now has been great Medium-control equipment abandoned by the system. The PLC is being widely used and he been gradually replaced the relay circuit logic control. With the leap in science and technology development, PLC also has been continuously improved and strong, while its functions and greatly exceeded the scope of control logic, such as communication and networking functions, such as self-diagnosis. So today we he such a device known as programmable logic controller, but we still referred to such devices used for PLC.
