            从环境保护角度考虑，煤改气的政策是造福于社会、造福于人民的，可从燃气锅炉运行费用来讲，企业成本的确增加很多。因此，从太阳能集热供水和供热工程所特有的环保性与经济性来看，的确是大有作为，从我们设计、安装过的工程，足以看到其环保性产生的社会效应和经济性为企业产生的巨大经济效益。 这个太阳能热水工程在设计初期，排污泵我们根据楼房设计图纸仔细重新进行测绘（很多建筑物在施工期间，多次修改施工图纸，实际尺寸与图纸往往有差距），将修改后发生变化的部分，进行重新标注，便于设计中各部分尺寸的准确性，以利于最后方便组装工作。在楼房的朝向最佳位置的中间，有一个较大的电梯机房，这样，上午日照偏东一些，西边部分影响日照；下午日照偏西一些，东边部分又影响日照。

       中开泵当建筑物面积又很有限时，只能够考虑最大限度地利用其建筑面积，按照传统的太阳能热水工程安装方法，根据纬度方式计算联集管角度，联集管每排之间还要留有一定的空间，防止阴影的遮挡问题，加之管道泵建筑物形状呈复杂的多边几何形状，十分的不规则，具有一定的设计和施工难度。 经过计算这个医院建筑面积约570平方米，多级泵减去电梯机房以及机房阴影部分和后边的20多个空调机组，实际可以使用的面积已不到500平方米了。在当时，国标《太阳能热水系统设计、安装及工程验收技术规范》GB/T18713-2002虽然刚刚制定但尚未公布。我们查阅国外的有关资料，看到很多国家早已采用了水平或小角度安装方式，翻译过来看了看，认为有一定的道理。

     如： 1、从流体力学分析，水的流动更加通畅，所以消防泵沿程损失比较小。 2、集热器系统上下转折路径很少，因此真空管中不易有沉积物。 3、在北方地区的夏季，早晨的太阳是从东北角升起，傍晚是从西北角落下，常规安装的斜置方式的太阳能集热器，有几个小时是照在集热器后面或侧面。太阳光可以理解为平行光，真空管是圆形的，大多数季节水平放置也照射180o，一天的日照时间更长一些，所以，可以增加吸收太阳的热能（我国南方影响不大，在北方应注意当地冬至季节真空管的阳光遮挡角度冬季日照辐射较弱，与夏季相差较大，越靠北的地区越发明显）。

           From the environmental point of view, from coal to gas policy is to benefit society for the benefit of the people can be in terms of running costs from the gas boiler, the cost does increase the number of enterprises. Therefore, water and heating from the solar collector project specific environmental and economical point of view, is indeed much to offer from our design, installation over the project, enough to see the environmental Suber-water pumpseffects of the social and economic enterprises the enormous economic benefits. The solar hot water project in the design stage, we carefully according to design drawings of buildings re-mapping (many of the buildings during the construction period, construction drawings revised several times, Shiji size and drawings often have gaps), the modified part of change, for re-marked, easy to design the various parts of the accuracy of measurements in order to facilitate easy assembly of the final work. Towards building the best place in the middle, there is a large elevatorScrew pumps machine room, so that some of the morning sunshine east, the west part of the impact of sunshine; afternoon sunshine west some of the east part of the further impact of sunshine. When the building area and very limited time, only able to consider to maximize their floor area, according to the traditional solar hot water installation method works, according to latitude means Jisuanlianji Guanjiao Duo, union pipe between every PaiMagnetic pumps Hai Yao left a certain space, to prevent the shadow of the occlusion, combined with the complexity of multilateral structures shape of a geometric shape is irregular, with some design and construction difficulties. After calculation of the hospital building area of about 570 square meters, minus the elevator machine room and the room behind the shadow of more than 20 parts and air conditioning units, the actual use of the area is less than 500 square meters of. At that time, the national standard "solar hot water system design, installation and engineering acceptance" GB/T18713-2002 Although just developed but not yet available. Our access to foreign information, see that many countries have already adopted the standard or small-angle mounting, translated looked at, that there Self-priming pumpsis some truth in it. Such as: 1, from the fluid dynamics of water flow more smooth, so relatively small losses along the way. 2, heating system up and down turn in the path very few, so easily have sediment in the tube. 3, in the northern summer, the morning sun is rising from the northeast, the northwest corner of the evening is falling, the conventional way inclined installed solar collectors, a few hours is shining in the back or side of the collector . Sunlight can be understood as parallel light, vacuum tubes are round, most of the season, also horizontal irradiation 180o, the day the sun longer, and therefore, can increase theChemical pumps absorption of the sun's heat (little effect on China's south, in the North should pay attention to local winter season of the vacuum tube angle winter sun block solar radiation is weak, with the summer much difference, the more obvious by the more northern areas).
