影响太阳能的使用年限缩短因素有哪些?

  想必大家都比较清楚,在正常情况下,太阳能热水器使用寿命长达15年左右,但是我们在使用过程中就会发现,热水器寿命往往并没有那么长。那么,造成太阳能热水器“短命”的原因有哪些呢,今天,济南力诺瑞特太阳能为您总结了以下几方面的原因:
Presumably, we all know that under normal circumstances, the service life of solar water heater is up to 15 years, but we will find that the service life of the water heater is often not that long. So, what are the reasons for the \"short life\" of solar water heaters? Today, Jinan linoret solar summarizes the following reasons for you:
一、光源水箱保温层采用全自动恒温高压定量发泡发泡均匀。

1、 The heat preservation layer of light source water tank adopts automatic constant temperature and high pressure quantitative foaming, and the foaming is uniform.

 

1.内胆
1. Inner bladder
目前,大部分太阳能热水器生产厂家都称水箱内胆是不锈钢。同样是不锈钢,但不锈钢中的铬和镍却大不相同。好的太阳能热水器采用高铬高镍的不锈钢内胆,保证了内胆坚固耐用,耐腐蚀性能强;劣质内胆多采用低牌号不锈钢,基本不含镍,耐腐性能差,使用寿命短。
At present, most manufacturers of solar water heaters call the tank stainless steel. The same is stainless steel, but the chromium and nickel in stainless steel are quite different. Good solar water heater uses high chromium and high nickel stainless steel liner, which ensures the tank is solid and durable, and has strong corrosion resistance; low grade stainless steel is used in poor quality tank, which basically does not contain nickel, with poor corrosion resistance and short service life.
2.保温层
2. Insulation layer
太阳能热水器白天生产的热水储存在储水箱里,如果保温层的保温性能不好,隔夜、阴雨天就不能用,或者不好用。造成太阳能热水器保温性能差的主要原因在于热水器的保温层,保温层的好坏决定了热水温度的高低和热水量的多少。好的保温层采用进口原材料,如聚氨酯,导热系数低,耐高温;保温工艺采用全自动恒温高压定量发泡,并经高温熟化处理,保温性能高且稳定持久。而一些低劣材料导热系数高,发泡也不均匀,一夜温度能下降十几度,遇到阴雨天就没有热水。
The hot water produced by the solar water heater in the daytime is stored in the water storage tank. If the thermal insulation performance of the thermal insulation layer is not good, it can not be used overnight or rainy days, or it is not easy to use. The main reason for the poor thermal insulation performance of solar water heater lies in the thermal insulation layer of the water heater. The quality of the thermal insulation layer determines the temperature and quantity of hot water. The good insulation layer adopts imported raw materials, such as polyurethane, with low thermal conductivity and high temperature resistance; the heat preservation process adopts automatic constant temperature and high pressure quantitative foaming, and after high temperature aging treatment, the insulation performance is high and stable and durable. However, some inferior materials have high thermal conductivity and uneven foaming. The temperature can drop more than ten degrees in a night, and there is no hot water in rainy days.
二、内置聚光反射板不受大气污染和侵蚀,聚光效果好,使用寿命长使用寿命长。
2、 The built-in spotlight reflector is free from air pollution and erosion, with good spotlight effect and long service life.
3.真空管
3. Vacuum tube
真空管是太阳能热水器的核心部件,也是太阳能热水器的“心脏”。它的质量直接决定了整台热水器的使用性能。真空管的使用性能受镀膜技术和清洗、镀膜、抽真空、封口等工艺的影响等。但是,一些超低价太阳能热水器采用的真空管具有以下缺陷:真空度低,只有质优产品的1/100;管内残留大量杂质和水汽,一遇到高温就变成气体,真空度降低;低真空状态下膜层稳定性能差,两三年之内膜层就老化、脱落,导致集热性能急剧衰减,无法吸收足够的热量。这是致命的。
Vacuum tube is the core component of solar water heater and the \"heart\" of solar water heater. Its quality directly determines the performance of the whole water heater. The performance of vacuum tube is affected by coating technology, cleaning, coating, vacuuming, sealing and so on. However, the vacuum tubes used in some ultra low price solar water heaters have the following defects: low vacuum, only 1 / 100 of the high-quality products; a large amount of impurities and water vapor remain in the tube, which will turn into gas at high temperature, and the vacuum degree will be reduced; under the low vacuum state, the stability of the film is poor, and the inner layer will be aging and falling off after two or three years, resulting in the sharp decline of heat collection performance and insufficient absorption The heat of. It\'s deadly.
