The maximum temperature of solar hot air can reach 200 degrees. Solar hot air technology can reach very high temperatures, depending on the design and material choice of the solar collection system. The solar hot air system uses solar radiation to convert light energy into thermal energy. After absorption and conversion by the collector, the air is absorbed. heated and generated High temperature hot air can reach temperatures above 100°C, or even exceed 200°C. Solar hot air can be used in many areas, such as industrial heating, drying processes, greenhouses, etc.
How high can a solar water heater reach in summer?
It depends on what type of solar water heater it is, whether it is a pressure type or a drip type. The temperature that a solar water heater can reach in a day is not too high. . In thisThis season it can reach 60 to 80 degrees. But if you don't use the hot water, the base temperature of the water in the water tank will be high the next day, so it will be much higher than the same temperature the day before. In fact, the maximum temperature a drip-style solar water heater can reach is 99 degrees, not 100 degrees. Because to reach the boiling point of 100 degrees, the instantaneous energy required is very high, and the energy of solar energy is very gentle. There's not a lot of energy at the moment. The maximum temperature a pressurized solar water heater can reach is 130 degrees. As we all know, under normal circumstances, the maximum temperature that water can reach is 100 degrees. If it reaches 130 degrees, that means it is not at normal atmospheric pressure. The water tank of a pressurized solar water heater is sealed. Once filled with water, the water froide heats up and expands, but it has nowhere to go. In other words, it must be equipped with a pressure relief valve. Otherwise it will explode like a bomb. It will automatically release pressure after reaching a certain pressure.
The temperature inside the water tank is 100 degrees maximum, but the vacuum tube can withstand temperatures of several hundred degrees, so don't worry.
When the temperature in the water tank exceeds 75 degrees, scale is easily produced. Therefore, when the weather is good in summer, the water tank should be filled with as much water as possible. This can go down appropriately. the water temperature. At the same time, water should be added at any time. But if there is no water in the water tank, although the water in the vacuum tube cannot be released, it will slowly evaporate when exposed to the sun for a long time peperiod, so there will be no water in the vacuum tube at this time. , water cannot be added during the day, otherwise the vacuum tube will burst.
