低温电热膜用于太阳热水器的实验研究

An Experimental Study of the Low Temperature Electric Heating Film Used in the Solar Water Heater

使用低温电热膜对平板型太阳热水器板芯加热,对其加热部位、加热面积、加热时间、加热功率进行了实验研究.结果表明:利用低温电热膜,可以使平板型太阳热水器在冬季避免结冰膨胀正常使用.

We conducted the experimental study about the heating area, heating time and heating efficiency of the heater, using the low temperature electric heating film to heat up the board|core of the plate solar heater. The result of the study indicated that the low temperature electric heating film enables the board|core of the plate solar heater to work normally in winter.
