为了推广应用太阳能,于1981年在机械厂浴池安装了一套太阳能热水器。这是本公司首次利用太阳能的实验。该热水器的太阳能接受面积为180平方米,全套设备结构简单,总投资为9万元。实际使用表明,该热水器在本地五、六月份使用时,平均每平方米每天可供热水65公斤。据实际标定,一般人每次洗浴平均需消耗热水60公斤,因此,该热水器可供195人使用。太阳能热水器与原来的蒸汽热水器相比,每月约可节约燃料费3000元,五年左右
In order to promote the application of solar energy, a set of solar water heaters was installed in the machine factory bath in 1981. This is the first time the company has used solar energy experiments. The water heater’s solar energy acceptance area is 180 square meters, and the complete equipment structure is simple, with a total investment of 90,000 yuan. The actual use shows that the water heater can provide 65 kg of hot water per square meter per day when it is used in May and June in the local area. According to actual calibration, the average person needs to consume 60 kilograms of hot water for each bath. Therefore, the water heater can be used by 195 people. Compared with the original steam water heaters, solar water heaters can save about 3,000 yuan in fuel per month, about five years.
