  工程联接管材的设计特别重要,如果系统管道设计不合理容易出现水头阻力太大,出水量小,热水供应量不足,有时可能出现热水短路等问题。严重的影响了系统的正常运行,管道设计上尽量要求水路平衡,管道口径要求与系统设计匹配,计算管道合理流量。
The design of Engineering connection pipes is especially important. If the piping design is unreasonable, the water head resistance is too large, the water volume is small, and the hot water supply is insufficient. Sometimes, there may be hot water short circuits and other problems. It seriously affects the normal operation of the system. As far as pipeline design is concerned, water balance is required as far as possible. Pipe diameter requirements are matched with system design, and reasonable flow rate of pipeline is calculated.

太阳能集热器是靠天吃饭,如果遇到阴雨雾雪天气太阳能光照不足,集热器无法获取足够的能量,这时太阳能工程不能满足正常用水要求,这时需要第二能源作为辅助。一般太阳能工程选择电加热管、电锅炉、燃气锅炉、燃油锅炉等辅助能源设备,设备型号选用要考虑到阴雨雾雪更大热水需求量,必免影响正常的热水需求,同时又要实现投资的经济合理性。

The solar collector is dependent on the weather, if you encounter a rainy fog and snow weather solar illumination is insufficient, the collector can not get enough energy, the solar energy project can not meet the normal requirements of water, then take second as auxiliary energy. General solar engineering selection electric heating tube, electric boiler, gas boiler, oil fired boiler and other auxiliary energy equipment, equipment type selection should take into account the rain fog snow maximum hot water demand, will affect the normal free hot water needs, but also realize the economic rationality of investment.
电气控制是太阳能工程的重要组成部分,它可以实现热水工程的智能化控制,比如:自动上水,水满自停,显示水温水位,自动或定时电加热、定时出水、冬季防冻 、管道循环以及增压等控制。控制系统选用特别重要,因为电气有一定的不稳定性,故障率较高,需要特别维护。控制系统要求正规厂家进行生产,这样才有系统质量保证。降低系统故障率,提高太阳能工程的整体性能。
Electrical control is an important part of solar energy project, it can realize intelligent control, hot water engineering such as: automatic Sheung Shui, water full stop, water temperature and water level display, automatic timing, timing or electric heating water, winter antifreeze, pipeline circulation and pressurization control. The selection of the control system is especially important, because the electricity has certain instability, the failure rate is high, and it needs special maintenance. The control system requires regular manufacturers to carry out production so as to have system quality assurance. Reduce the failure rate of the system and improve the overall performance of solar energy engineering.
太阳能工程能够提供出连续不断的热水,这就须要有充足的水源进行补充。一般采用浮球箱作为补水工具,浮球箱可以起到限流限压作用,对太阳能工程补水稳定,安全可靠。在北方寒冷季节,需要对浮球箱进行保温必要时在内部增加电加热,保证冷水能够及时补充,不影响系统正常运行。
Solar energy projects can provide continuous hot water, which requires adequate water supply. The floating ball box is generally used as a water supplement tool. The floating ball box can be limited to the current limiting pressure, and it is stable and safe for the solar energy project. In the cold season of the north, we need to keep the floating box for heat preservation. If necessary, we need to increase the electric heating internally to ensure that the cold water can be replenish in time, without affecting the normal operation of the system.
