Solar Roof Water HeatersSolar roof water heaters are an environmentallyfriendly and cost-effective solution for domestic hot water needs. These systems harness the power of the sun to heat water, reducing reliance on traditional energy sources like electricity or gas. In this article, we will explore the principles, benefits, and installation considerations of solar roof water heaters.The basic principle behind solar roof water heaters is straightforward: they collect solar energy through absorber plates mounted on the roof and transfer this heat to the water stored in a tank. The absorber plates are typically coated with a material that efficiently absorbs solar radiation and converts it into heat. This heat is then transferred to the water through a series of pipes and heat exchangers.One of the key benefits of solar roof water heaters is their environmental friendliness. By harnessing renewable solar energy, these systems significantly reduce carbon emissions associated with traditional heating methods. Additionally, they offer significant cost savings over thelong term, as solar energy is free and abundant. This can lead to substantial reductions in energy bills, especiallyin areas with high electricity prices or limited access to fossil fuels.Installation considerations for solar roof waterheaters vary depending on the specific system and theroof's characteristics. However, some general guidelinescan be followed. It is important to ensure that the roof is structurally sound and able to support the weight of the solar collector and associated piping. Additionally, the installation location should be chosen to maximize exposure to sunlight, avoiding shading from trees or other obstacles. Maintenance of solar roof water heaters is generally straightforward. Periodic inspections and cleaning of the absorber plates may be necessary to ensure optimal performance. Additionally, it is important to monitor the water temperature and pressure to ensure that the system is operating efficiently.In conclusion, solar roof water heaters offer a sustainable and cost-effective solution for domestic hot water needs. By harnessing the power of the sun, thesesystems reduce reliance on traditional energy sources,lower carbon emissions, and save money on energy bills.With careful installation and maintenance, solar roof water heaters can provide reliable and efficient hot water for years to come.**太阳能屋顶热水器**太阳能屋顶热水器是一种环保且成本效益高的家庭热水解决方案。

Split Solar Water HeaterMy hometown is Yunnan, where the penetration rate of solar water heater has reached 90% in cities since adequate sunshine, but most of them are traditional forms of solar water heaters. So I introduce a new form of solar water heater: split solar water heater.Recalling Traditional solar water heater , in order to make the low temperature water hot, the traditional double-decker vacuum tube solar water heater rely on many independent heat pipe to has the working substance evaporated and then condensation, thus putting the heat to the low-temperature water Through this process ,however, the disadvantage of such water heater is: a lot of holes will be drilled on the tank, and it’s willresult in heat loss.Figure-1 Traditional Double-decker vacuum tubeIn Figure-1, 6 is Hot water , 5 is Tank , 4 is Cold water , 3 is Sealing plug, 2 is Evaporator tube,1 is Vacuum tube.The new Split solar water heater has obvious advantages Compared to Traditional double-decker vacuum tube solar water heater ,it not only Requiring a lower level of accuracy, but also the evaporators be located at different heights can match up to the a same condenser at the same time.In split solar water heater, workingsubstance will evaporate after absorbing luminous energy when the evaporator tubes are exposed in the sun at the beginning, and then liquefaction of working substance will flows back to evaporator tube, after the working substance in the hot gas condition transfer the heat to the low-temperature water, flowing as follows:Evaporator tube→Joint→ box →Steam riser→Condenser→Condensation pipe→Joint box→Evapo ration tube.Figure-2 New Split solar water heaterIn Figure-2,1 is steam riser ,2 is hot water 3 is condensation pipe ,4 is Evaporator tube,5 is cold water,6 is condenser,7 is joint box, 8 is tank.Initially, there is a small part of working substance participate in the thermal cycle, but evaporation and condensation of these working substance not enough to transfer all the heat which is the evaporator tube absorbed, little by little, the working substance of a new cycle will greater on the quality then last cycle, with the working substance gradually less and level rise on joint box, evaporation and condensation will reach the dynamic balance in all working substance take part in.Because the tank will permit to be placedin interior, this will efficaciously reduce heat dissipation, and only 4 holes on the tank, will also reduce heat loss. Just in the meantime,the split soar water heater can add electric heating system or gas heating system so that users can also enjoy the warm water even in the rainy day.Improving program:Not only in view of the solar power panels installed on the housing is not pleasing to tour eyes and affect the interior lighting, but also difficult to repair. Proposed small-scale community or school set up unified solar power hot water supply station, put absorb solar power panels and water tanks are concentrated in one place, setting a unified water supply center, can make full use of resources and convenient the life of Community residents.。

附录SOLAR WATER HEATING BACKGROUND Using the sun’s energy to heat water is not a new idea. More than one hundred years ago, black painted water tanks were used as simple solar water heaters in a number of countries. Solar water heating (SWH) technology has greatly improved during the past century. Today there are more than 30 million m2 of solar collectors installed around the globe. Hundreds of thousands of modern solar water heaters, such as the one shown in Figure 1, are in use in countries such as China, India, Germany, Japan, Australia and Greece. In fact, in some countries the law actually requires that solar water heaters be installed with any new residential construction project (Israel for example).Figure1: Evacuated Tube Solar Collector in Tibet, China In addition to the energy cost savings on water heating, there are several other benefits derived from using the sun’s energy to heat water. Most solar water heaters come with an additional water tank, which feeds the conventional hot water tank. Users benefit from the larger hot water storage capacity and the reduced likelihood of running out of hot water. Some solar water heaters do not require electricity to operate. For these systems, hot water supply is secure from power outages, as long as there is sufficient sunlight to operate the system. Solar water heating systems can also be used to directly heat swimming pool water, with the added benefit of extending the swimming season for outdoor pool applications.◆Solar Water Heating Application MarketsSolar water heating markets can be classified based upon the end-use application of the technology. The most common solar water heating application markets are service hot water and swimming pools.◆Service hot waterThere are a number of service hot water applications. The most common application is the use of domestic hot water systems (DHWS), generally sold as “off-the-shelf” or standard kits as depicted in Figure 2.Figure2: Solar Domestic Hot Water System in AustraliaSwimming poolsThe water temperature in swimming pools can also be regulated using solar water heating systems, extending the swimming pool season and saving on the conventional energy costs. The basic principle of these systems is the same as with solar service hot water systems, with the difference that the pool itself acts as the thermal storage. For outdoor pools, a properly sized solar water heater can replace a conventional heater; the pool water is directly pumped through the solar collectors by the existing filtration system.Swimming pool applications can range in size from small summer only outdoor pools, such as the one shown at a home in Figure 3, to large Olympic size indoor swimming pools that operate 12 months a year.Figure 3: Unglazed Solar Collector Pool Heating System in Canada◆Description of Solar Water Heating SystemsSolar water heating systems use solar collectors and a liquid handling unit to transfer heat to the load, generally via a storage tank. The liquid handling unit includes the pump (used to circulate the working fluid from the collectors to the storage tank) and control and safety equipment. When properly designed, solar water heaters can work when the outside temperature is well below freezing and they are also protected from overheating on hot, sunny days. Many systems also have a back-up heater to ensure that all of a consumer’s hot water needs are met even when there is insufficient sunshine. Solar water heaters perform three basic operations as shown in Figure 4:Collection: Solar radiation is “captured” by a solar collectorTransfer: Circulating liquid transfer this energy to a storage tank;circulation can be natural (thermo siphon systems) or forced, using a circulator (low-head pump); andStorage: Hot water is stored until it is needed at a later time in a mechanical room, or on the roof in the case of a thermo siphon system.Figure 4: System Schematic for Typical Solar Domestic Water Heater◆Solar collectorsSolar energy (solar radiation) is coll ected by the solar collector’s absorber plates. Selective coatings are often applied to the absorber plates to improve the overall collection efficiency. A thermal fluid absorbs the energy collected.There are several types of solar collectors to heat liquids. Selection of a solar collector type will depend on the temperature of the application being considered and the intended season of use (or climate). The most common solar collector types are:unglazed liquid flat-plate collectors; glazed liquid flat-plate collectors; and evacuated tube solar collectors.◆Unglazed liquid lat-plate collectorsUnglazed liquid flat-plate collectors, as depicted in Figure 5, are usually made of a black polymer. They do not normally have a selective coating and do not include a frame and insulation at the back; they are usually simply laid on a roof or on a wooden support. These low-cost collectors are good at capturing the energy from the sun, but thermal losses to the environment increase rapidly with water temperature particularly in windy locations. As a result, unglazed collectors are commonly used for applications requiring energy delivery at low temperatures (pool heating, make-up water in fish farms, process heating applications, etc.); in colder climates they are typically only operated in the summer season due to the high thermal losses of the collector.Figure 5: System Schematic for Unglazed Flat-Plate Solar Collector◆Balance of systemsIn addition to the solar collector, a solar water heating system typically includes the following “balance of system components”1. Solar collector array support structure, as depicted in the Figure 6;Figure 6: Solar Array Support Structure2. Hot water storage tank (not required in swimming pool applications and in some large commercial or industrial applications when there is a continuous service hot water low).3. Liquid handling unit, which includes a pump required to transfer the fluid from the solar collector to the hot water storage tank (except in thermo siphon systems where circulation is natural, and outdoor swimming pool applications where the existing filtration system pump is generally used) .it also includes valves, strainers, and a thermal expansion tank.4. Controller, which activates the circulator only when usable heat is available from the solar collectors (not required for thermo siphon systems or if a photovoltaic-Powered circulator is used).5. Freeze protection, required for use during cold weather operation, typically through the use in the solar loop of a special antifreeze heat transfer fluid with a low-toxicity. The solar collector fluid is separated from the hot water in the storage tank by a heat exchanger; and.6. Other features, mainly relating to safety, such as overheating protection, seasonal systems freeze protection or prevention against restart of a large system after a stagnation period. Typically, an existing conventional water heating system is used for back-up to the solar water heating system, with the exception that a back-up system is normally not required for most outdoor swimming pool applications.太阳能热水系统研究背景利用太阳能来加热水的并不是一个新的想法。

电容式传感器
1.简介
电容式传感器可以直接感应各种物理量—位移,化学成分,电场等,并且能间接感应其他许多变量——能被转换成位移或介电常数的各类物理量,例如压力,加速度,液位,液体的组成。
它们是通过施加5V电压的检测电路将变化量转化为电容电压,频率或脉冲宽度的变化量。
电容式传感器的应用范围非常广泛。
1907年,第一次提到电容式传感器是在《自然》上,但是它的特点是很少传感器所具备的。
令人惊奇的是,随着低成本的技术及其良好的稳定性,和简单的调节电路的实现,传感器的偏移和增益调整不是必需的,作为电极的原始输出信号的电容跨度几乎可以与电源接轨。
这些优势可以用来进行许多转换。
经常听到的反对电容式传感器技术的说法,它是对湿度敏感的不稳定和对高阻抗电路的需要。
事实上,潮湿空气也只比干燥的空气介电常数高百万分之一,因此湿度本身也没有什么问题。
但对于适当的电路设计和印刷电路板布局,电容式传感器和其他类型的传感器也有着区别。
他们不能承受放置在潮汐或凝结的空气中,只有少数的电路可以。
设计过程通常遵循以下步骤
1)电极板的设计来衡量所需的变数。
电容的最大值与极板面积和极板间距有关2)通过把电容加上适当的电路来防范或屏蔽电极传感器的杂散电容和串扰
3)计算传感器电容,杂散电容和输出信号摆幅
4)指定转换的功能,如E
0= C(面积线性),E
= 1/C(间距线性)。
使用两个高精
度平衡电容器,例如传递函数C1/C2或(C1- C2)/(C1 + C2)
5)选择一个激励频率足够高降低噪音。
通过增加激发频率来降低外部和内部电路产生的噪音
6)设计电路,既要以满足精度为目标,也要考虑外界环境
1.1应用
电容式传感器具有广泛的用途。
如:
1)将流量通过电容传感器转化为电信号,电容式传感器也可以用来测量位移。
2)具有稳定灵敏偏转特性的探测器可以用来测量压力。
3)电容液位传感器,可以放置在导电液体的上方,或用于测量非导电油箱外板的电容变化,测量箱内的液位
4)间距——需要将放置金属物体附近的电容电极靠的比较近。
5)扫描多片传感器–单板间距测量可以推广到多板间距测量。
导电和绝缘的表面都可以测量。
6)厚度测量 -测量其介电常数已知的绝缘体厚度,或介电常数已知的接触板的厚度。
7)冰探测器 -飞机机翼结冰可检测机翼前缘使用的绝缘金属条。
8)轴角或直线位置-电容式传感器可以测量角度和位置,用multiplate方案给出精度高和数字形式的输出,或用一种较少的绝对准确性,但更快的响应和更简单的电路模拟输出。
9)灯调光开关-普通金属板软触摸灯调光器采用60Hz的激励和感应到人体的电容。
10)钥匙开关- 利用电容式按键开关,或用手指移动导电柱塞使两个小板之间的耦合中断。
11)限位开关 -限位开关可以探测到一个电容的增加。
12)XY坐标- 电容大小不同的图形输入可作为输入设备电脑鼠标的XY坐标,手指触摸敏感,Z轴敏感和手写笔激活的设备都可供选择。
13)加速度计-ADI公司推出了1.5克的敏感性集成加速芯片。
有了这种敏感性芯片的设备可以作为一个倾斜仪。
2. 电容的计算
2.1最简单的电极结构是两个一定间距的平行板所构成的。
图1平行板
图1为100毫米×100毫米尺寸和间距为1mm钢板所组成的电容器,(忽略边
缘影响),在真空中的电容是88.54 pF。
真空介电常数εr或相对介电常数K为1,空气电介质常数增加至1.0006。
如塑料或油电介质材料具有典型3-10的介电常数,水等流体具有50或者更高的介电常数。
边缘通量的影响,如果极板接近板间距,图1计算是准确的。
但是,随着板间距的增加而使相对面积增加,更多的磁力线就可以通过边缘和板背上,测量电容可以远远大于计算值。
图2 同轴圆柱
2.2任意形状的电极电容
计算任意电极电容涉及到了柏松定律。
简单说,通常可以解决径向或矩形对称的电容计算,但是对于计算相对复杂形状的电容是比较困难的。
对于非对称电极,可近似解。
磁力线素描能够产生出近似正交的磁力线和等势面,并通过素描的面积来计算出电容的大小。
有限元素分析软件和其他方面提供相当于执行一个粗略的磁场线素描。
有限元素分析程序可以处理二维或三维制作电容值的磁力线图。
3.位移测量
电容式传感器常用于直接与非接触式角度测量,以及测量线性位移,极板间距。
根据测量工作的使用,传感器电极有几种不同的安装。
对于小位移精确测量,线性变化的间距是最好的,但是测量别的,面积变化是最好的。
三电极系统可以提高性能,在许多板块并行使用,增加电容。
多板可以独立处理,以便更好的得到高精度的测量值。
4.传感器其他测量量
电容式传感器直接检测电极的位移,导电或绝缘物体的位移,或使用材料的介电性。
所有其他变量都必须先转换成其中之一。
由于该技术具有优秀的,稳定的,低噪声检测的能力,这种间接的方法效果很好。
图3等效电路
电容的等效电路可以近似于此电路,串联电阻小,为我们高阻抗使用忽略电感。
良好的介电层电容器具有非常大的分流电阻;聚丙烯电容器使用寿命已超过300小时。
其他材料具有更小的分流电阻,有时达到了电容阻抗的5-10%。
虽然介电常数K是最稳定的,但分流电阻或同等水平的损耗角正切可能会显示与材料性能或与频率有很大差异。
例如,干皮的损失角正切为0.045,但有15%相对湿度的干皮的损耗角正切增大到1.4。
当空气在1100千赫损耗正切0.0001辛烷值,但在91辛烷值损失正切上升到0.0004
水有一个高K(80)和一个损失角正切在低频率达到高峰,又在1010 Hz这种高介电活动,损失角正切或水的介电常数可以用来检测材料的水分含量。
另一个电容器电介质特性,可能有一些材料性能检测的使用介质吸收。
它是通过检测一个电容器充电、放电10秒,再现后15分钟的变化。
一个相对低质量的介质如镀铝纸有10%的电介质吸收。
5.信号调理
信号调理电路转换成电压、频率或脉冲宽度调制电容变化。
简单的电路都可以使用,但简单的电路可能由泄漏或杂散电容的影响,可能不适合应用于微小电容的测量。
图4 RC振荡器
RC振荡器中一个间距变化的电容器将会产生一个线性间距的频率输出,一个面积变化的电容器则可以用来测量线性化的脉冲宽度。
如图4所示电路没有容纳杂散电容的方式。
例如,电容器是由同轴电缆连接,电缆的电容,增加了被测电容的稳定性和灵敏度。
通常,计算机软件可以用来校正这些错误,但同步解调器电路是一个更好的选择。
RC振荡器的另一个缺点是电容是相对于固定电阻,电阻温度的升高导致系数不稳定影响到电路测量。
电容解调器中电桥的使用使得测量电路的精度更加高。
6.缺点
相对于其他类型的传感器,高阻抗电容式传感器需要特殊处理。
次微安直流或交流信号耦合到放大器的输入必须防止一些可能的危害。
6.1 泄漏
小型传感器板可能有几兆欧的放大器输入阻抗,所以需要几百兆欧的阻抗防止泄漏。
泄漏路径通常在印刷电路板表层,通常由下面几种情况所致:
1)松香残留或润滑油收集空气中的杂质
2)导电残留物
3)油漆,碳的着色
4)较高的湿度
防止泄漏
一种典型的高阻抗放大器是可以用来防止表面泄漏。
图18保护泄漏路径的低阻放大器
运算放大器的输入偏置电流可以低至10fA。
由大小为1015欧姆的表面泄漏电阻而引起的泄漏电流和运算放大器的偏置电流相等,能够使放大器输出达到一个极值。
仔细清洁或保形涂层将对防止泄漏有所帮助,但是一个简单的保护技术是最好的。
如上图所示带有接地印刷电路轨迹的防泄装置采用点线式中断泄漏路径。
因为阻焊层是在保护轨迹上对表面电流进行追踪,所以它必须在保护箔上予以解除。
6.2静电
静电电荷可以在绝缘体附近由于电容式感板摩擦而产生,从而导致在一些危险情况下引起火花。
在更严重的情况下,一种积聚50-100V的电荷不会产生电弧,但会对机械振动产生有害的敏感性。
这种敏感性由恒电容器电荷电压V = Q / C产生,由于振动随间距变化而变化的电容可以驱动放大器输入超过极值。
6.3噪声
电容传感器的信噪比是指励磁电压和放大器电压噪声的比率。
最佳信噪比的励磁电压是5-500 V。
一个高阻抗放大器可能含有一个或两个nVper根赫兹。
这就提供了在1赫兹带宽下大小为2x109-5x1011的信噪比。
如果放大器的电流噪声和高阻抗传感器一样是一个抽象因素,或者放大器输入电容大于传感器的电容,那么这个理论极值将会降低。
