The structure of the water tank of the flat panel solar water heater is as shown below: It can be seen from the picture that due to the pressure structure of the water tank, if the outlet hot water pipe is not turned on, water cannot flow out of the cold water pipe under the action of atmospheric pressure. When draining, the hot water outlet must be opened so that water from the water tank can flow out. Turn on the apartment's hot water pipe and cold water pipe. -panel solar water heater at the same time, and the water can be discharged from the cold water pipe
< p>Half an hour.
It takes about half an hour to install solar water. When filling the solar water heater, it is better to fill the water in the air without high temperature. The best time is two hours before sunrise or after sunset. Since the vacuum tube is produced using the production linethe most advanced fully automatic vacuum cleaner in the world, it has a high vacuum degree, 100 times that of the national standard. It has good thermal insulation effect, high heat collection efficiency and fast heating speed.
Since the air drying temperature is extremely high, if solar energy is replenished at high temperatures, the tube will explode due to the large temperature difference. In addition, because the temperature inside the vacuum tube can reach about 250°C when it air-drys, there is no water in the water tank or the first filling of Water should be carried out before sunrise or half an hour after sunrise. the sun sets.
Precautions for using solar energy
During the installation process of solar equipment, there may be stains or oil stains on the inside the water pipes, so after the installation, you need to open the faucet, discharge the internal residue to ensure normal use. In addition, when using solar equipment every day, pay attention to hygiene and cleanliness to ensure the surface is clean.
If solar energy has not been used for several days and the weather is relatively good, the water inside the solar panel will become very hot. If it is suitable for the use of hot water, special precautions must be taken. to avoid being heated by burnt hot water. In addition, a filter will be installed at the tap water outlet. Over time, stains will accumulate and need to be treated in time.
