太阳能热水系统是将太阳能转换成热能以加热水的装置。通常包括太阳能集热器、贮水箱、泵、连接管道、支架、控制系统和必要时配合使用的辅助能源。
Solar water heating system is a device that converts solar energy into heat energy to add hot water. It usually includes solar collector, storage tank, pump, connecting pipe, bracket, control system and auxiliary energy when necessary.

太阳热水系统主要由太阳集热系统和热水供应系统构成,主要包括太阳集热器、储热水箱、循环管道、支架、控制系统、热交换器和水泵等设备和附件。太阳集热系统是太阳热水系统特有的组成部分,是太阳能是否得到合理利用的关键。

The solar hot water system is mainly composed of the solar collector system and the hot water supply system. It mainly includes solar collector, heat storage tank, circulating pipe, support, control system, heat exchanger and water pump and other equipment and accessories. The solar collector system is a unique part of the solar hot water system. It is the key to the rational utilization of solar energy.
太阳能采暖系统主要由真空管集热器、储热保温水箱、地板采暖系统以及控制系统等组成,可分为以下三个部分了解整体系统的运行:
The solar heating system mainly consists of vacuum tube collector, heat storage and heat preservation tank, floor heating system and control system. The system can be divided into three parts to understand the operation of the whole system.
1、太阳能照射真空管,真空管集热器把水加热,通过循环系统将热水储存在保温水箱中。如下图所示:集热器可以将水加热到50度,此时红色箭头所示为加热水循环,水温可达到系统要求,所以电加热是关闭的状态;
1, the solar energy irradiate the vacuum tube, the vacuum tube collector collectors the water to heat, passes the circulation system to store the hot water in the heat preservation water tank. As shown below: the collector can heat the water to 50 degrees, at this time the red arrow shows the heating water cycle, the water temperature can reach the system requirements, so the electric heating is closed.
2、水温达到系统要求,通过换热器将热量换到地暖盘管中,再由地面均匀地向室内敷设热量,地板采暖系统如箭头所示进行系统循环;
2, the water temperature to meet the system requirements, through the heat exchanger to change the heat to the heating coil, and then evenly ground the ground to the indoor heat, floor heating system, such as arrow shows the system cycle.
3、当太阳能集热达不到地暖系统所需温度,开启电加热保证水温,如图所示,电加热为红色开启状态。
3, when the solar heat collection does not reach the temperature required by the floor heating system, the electrical heating is opened to ensure the water temperature.
太阳能热水系统应遵守的国标:
The national standard of solar hot water system should be observed:
太阳热水器系统设计、安装及工程验收技术规范GB/T18713-2002
Technical specification for design, installation and engineering acceptance of solar water heater GB/T18713-2002
太阳热水系统性能评定规范 GB/T20095-2006
Specification for performance evaluation of solar hot water systems GB/T20095-2006
民用建筑太阳能热水系统应用技术规范 GB/T50364-2005
Technical specification for solar water heating systems in civil buildings GB/T50364-2005
不同于一般安装在室内的电热水器、燃气热水器,太阳能热水器都是安装在室外,因此,还需要考虑室外环境情况,主要是以下几点:
Different from the electric water heater, gas water heater and solar water heater which are installed in the room, the solar water heater is installed outside. Therefore, the outdoor environment needs to be considered, and the main points are as follows:
(1)固定:防风固定一定要做好,一般安装都采用钢丝绳牵住太阳能支架,固定到周围比较坚固结实的地方,这样经济节约;另一种方法是预埋按章底座,将太阳能固定在底座上,相比钢丝绳,虽然造价会高一些,但是使用更加安全放心。
(1) fixed: the wind fixing must be done well, the general installation uses the steel wire rope to hold the solar energy support, fixed to the strong and strong place around, so the economy is economical; the other way is to bury the base of the seal, the solar energy is fixed on the base, compared with the wire rope, although the cost will be higher, but use more. Be safe and secure.
(2)防雷:太阳能热水器多安装在楼顶,属于建筑物更高的地方,更好是在距离热水器50公分的地方安装上避雷设施,并且与建筑物避雷系统的地下引线相连接,起到避雷的作用。
(2) lightning protection: the solar water heater is installed on the top of the building, which is the highest place in the building. It is best to install the lightning protection facilities in the place where the water heater is 50 centimeters. And it is connected with the underground lead of the building lightning protection system to play the role of lightning protection.
(3)保温:一般情况下,室外管道越短越好,并且做好保温、固定工作,包好保温料,保证冬季寒冷条件下管道不致冻裂;固定好管道,则可以防止大风等恶劣天气下,不致摇摆。

(3) thermal insulation: in general, the shorter the better the outdoor pipe, and good insulation, fixed work, wrap good insulation, to ensure cold conditions in the winter conditions, pipes do not freeze cracking; fixed good pipes, it can prevent bad weather, such as wind and other bad weather, not to swing.
