The maximum temperature of water placed in solar is 100 degrees.
However, solar power design requires the temperature to reach 45 degrees and not exceed 60 degrees. This beach is the best. Water temperatures above 80 degrees can easily damage the water tank! If solar energy is not used for a long time, it is likely that the temperature inside will reach 100 degrees every day.
Generally, the water temperature of vacuum tube solar water heaters can reach more than 60 degrees Celsius in summer and around 45 degrees Celsius in winter. The vacuum tube cannot be adjusted and will continue to heat in cloudy weather. and on rainy days, high-power electric heating system is used, but it is better than ordinary electric heating which consumes more electricity.
Since solar water heatersFlat panel displays use advanced heat collection plate cores, the heat absorption rate of the plate core is higher than that of vacuum tubes. Water temperatures can reach over 90 degrees Celsius in summer. and around 70 degrees Celsius in winter. In addition, flat panel solar water heaters can adjust the water temperature by themselves, greater freedom of use in rainy days, electric heating design is adopted, which can save 70-90%. energy than ordinary electric water heaters.
Factors that affect water temperature of solar water heaters:
1. The ratio of water volume to heat collection surface area for the same volume of water tank, if water diameter; The tank is reduced and the length of the water tank is extended. More heat collecting tubes can be placed and the water temperature will naturally increase. VS'is the most effective way to increase water temperature.
2. The quality of the glass collector tube coating; if the quality of the vacuum tube coating is good, its heat absorption performance will be better, its performance will decline more slowly, and the water temperature will of course be higher. .
3. The leaving water temperature; the morning water temperature is 60 degrees, which is of course higher than the morning water temperature which is 20 degrees. If you use less water, more water will remain and the water temperature will be higher; if the water temperature is higher, you will use less water, and the water temperature will be higher if you use more water; the temperature will be lower; if the water temperature is lower, you will use more water and the water temperature will not be higher.
4. The thermal insulation performance of the water tank ; Of course, the water temperature will be higher if the thermal insulation performance is good.
5. Meter accuracy; the same water will give different readings. This is a meter accuracy issue.
1. The temperature of the flat collector in the air is low, around 140℃;
2. around 120℃. The heat absorption and dissipation of the flat plate collector will reach a balance at about 120℃, so when the water tank temperature is too high, the temperature difference cycle can be stopped and the average vaporization loss of the collector will be less.
(In fact, during dealer survey and laboratory testing, the maximum temperature of the flat collector water tank did not exceed 95℃)
