怎么样选购太阳能热水器?
来源:http://www.sdlntyn.com 发布时间:2018-12-18 10:10:55 浏览次数:183
与电热水器和燃气热水器比较,太阳能热水器有许多优点:
Compared with electric water heater and gas water heater, solar water heater has many advantages:
1、太阳能取之不尽、用之不竭。只需有阳光,太阳能热水器就可进行光热转化,一年四季均可运转;
1. Solar energy is inexhaustible and inexhaustible. With only sunlight, solar water heaters can be converted into heat and light, and can be operated all the year round.
2、绿色环保。太阳能作为一种洁净的可再生动力,无环境污染,无安全隐患;
2. Green environmental protection. As a clean renewable power, solar energy has no environmental pollution and no potential safety hazards.
3、使用寿命长,首要部件使用寿命可达十五年以上;
3. Long service life, the service life of the main components can reach more than 15 years.
4、与其它动力配套使用,可完成全天候运转;
4. It can complete all-weather operation if it is used in conjunction with other powers.
5、经济效益明显。一次出资而长期获益是太阳能热水器的明显特点。太阳能热水器的回收期同与之比较的惯例动力的价格有关,一般情况下,可在1~4年内悉数回收出资。
5. Obvious economic benefits. The obvious feature of solar water heaters is to invest once and benefit for a long time. The payback period of the solar water heater is related to the price of the conventional power compared with the solar water heater. Generally, all the investment can be recovered within 1 to 4 years.
一步:断定用水量
Step 1: Determine water consumption
首先应清晰用户常住人数、人均用热水量,然后算出一天的热水总量,再依据热水总量以及1m2太阳能集热器产热水能力F(75—90kg/天·m2),规划太阳能集热器面积S(m2)以及保温水箱容量V(m3)。依据咱们多年的经验,用户人均用55°C的热水量可以参考以下参数:

Firstly, the number of resident users and the amount of hot water per capita should be clearly defined, and then the total hot water in one day should be calculated. Then, according to the total hot water and the hot water production capacity F (75-90 kg/day.m2) of 1 m2 solar collector, the area S (m2) of solar collector and the capacity V (m3) of thermal insulation tank should be planned. Based on our years of experience, the user per capita hot water consumption of 55 C can refer to the following parameters:

1. 家庭用户:花洒喷淋用水80—100kg/人·天,或每人配置1m2的太阳能集热器面积;
1. Home users: 80-100kg/person/day for spraying water, or 1 m2 solar collector area per person;

2. 工厂员工、学校花洒喷淋式用水:40—60kg/人·天;

2. Sprinkler water for factory employees and schools: 40-60 kg/person/day;
3. 宾馆花洒喷淋用水:80—120kg/人·天;
3. Hotel sprinkler water: 80-120 kg/person/day;
4. 泡浴缸用水:300—500kg/人·天。
4. Water for bathtub: 300-500 kg/person/day.
断定一天的用热水总量P(kg),把P(kg)÷F(kg)/m2,即可得太阳能集热器面积S(m2),按每平方米太阳能集热器配0.1m3的保温水箱容量的配比联系,可算出保温水箱容量:V=S(m2)*0.1m3/m2。
It is concluded that the total amount of hot water used in a day is P(kg)F(kg)/m2, i.e. the area of solar collector S(m2). According to the ratio of 0.1m3 thermal insulating water tank capacity per square meter solar collector, the thermal insulating water tank capacity can be calculated as V=S(m2)*0.1m3/m2.
太阳能热水器的造价与太阳能集热器的面积和保温水箱容积有直接联系,接近于正比联系,从用户久远的、综合的利益视点考虑,适当选择大一点的太阳能集热器面积,对用户有利,由于初次多出资一点太阳能热水就充足一些,以后15年就更省运转费用。
The cost of solar water heater is directly related to the area of solar collector and the volume of heating tank, which is close to proportional relationship. Considering the long-term and comprehensive interests of users, it is beneficial for users to choose a larger area of solar water collector appropriately. As the initial investment of more solar water is sufficient, the operation cost will be saved in the next 15 years.
