People often sweat in summer, and the number of natural bathing has also increased. In addition, with abundant solar energy in summer, solar water heaters are used more and more frequently. However, most people only know that the maintenance of solar water heaters in winter is very important. As everyone knows, solar water heaters need to pay more attention to care in summer. Today, I will introduce to you what you need to pay attention to during the use of solar water heaters in summer.
1. Choose the time of Sheung Shui scientifically.
The solar water heater needs to be watered regularly, but it is strictly forbidden to water it when the weather is particularly hot and the water temperature is particularly high, and it is strictly forbidden to add water immediately after the water is used up. Because of the strong sunlight in summer, the solar vacuum tube is exposed to the sun, and the air temperature is as high as 270 degrees Celsius to 400 degrees Celsius. At this time, the water can easily cause the vacuum tube to burst. It is best to use it in the morning before sunrise or two hours after the sun sets at night Water, this can ensure the service life of the solar vacuum tube.
2. Reasonably adjust the hot and cold water valve.
The water temperature adjustment steps of solar water heaters: first open the cold water valve, adjust the flow of cold water appropriately, and then open the hot water valve to adjust until the desired bath temperature is obtained.
Due to the prolonged time of the sun in summer, the temperature is higher, and the domestic hot water consumption is less. Therefore, the hot water in solar water heaters tends to have a relatively high temperature, generally up to 60 degrees Celsius. For ordinary households, the distance between the water storage point and the water point of solar water heaters is often longer, and the water temperature in the water pipe can reach about 35 degrees Celsius due to the high temperature in summer. Therefore, when we turn on the water heater, the normal temperature hot water in the water pipe will be discharged first, and after a minute or two, the hot water will be discharged. If we are not careful, it may scald the skin. Therefore, pay attention to the temperature of hot water when using the water heater in summer.
3. Use the last hot water cleverly.
Clever use of the last hot water can save resources better. When taking a bath, if the water in the solar water heater has been used up, and the person has not rinsed it out, you can use cold water for a few minutes, using the principle of sinking cold water and rising hot water to push out the hot water in the pipe, and you can continue After taking a bath; if there is still a little hot water in the solar water heater after bathing, use cold water for a few minutes, and the hot water can wash one more person; in addition, pay attention to the shower head not to face the human body when adjusting the water temperature to avoid scalding.
4. Appropriately determine the amount of water in the water supply.
Decide the amount of water in the water according to the weather conditions, and you can get a more satisfactory water temperature. If the next day is sunny, you can fill the water; if it is cloudy or cloudy, the upper half tank of water; if there is rain all day, keep the original water Serve cold water.
5. Regularly inspect and maintain the pipeline.
Regularly check the exhaust holes to ensure that they are unblocked, so as not to swell or collapse the water tank; solar water heaters with auxiliary electric heating devices pay special attention to water supply to prevent dry burning without water. At the same time, check whether the solar water pipe insulation layer and UV protection tape are aging and cracked. If the water pipe is exposed, it will become hard and brittle under the sun, cracking and leaking. It is best for users to install an insulation layer and anti-ultraviolet tape in advance to fully protect the water pipe.
6. Avoid accidents in thunderstorms and windy weather.
The solar water heater must be installed on the top balcony due to its working principle, and the solar water heater is usually larger due to the heat collection requirement. Therefore, users should pay attention to strengthening the bracket of the solar water heater in windy weather to prevent accidents. Be sure to fill the water heater with water on a windy day to increase stability.
7. Protective measures should be taken when solar water heaters are not used for a long time in summer.
At present, most solar water heaters use evacuated heat collection tubes. This type of evacuated heat collection tube has a higher absorption efficiency. In summer, when the outside temperature is high, the sunshine time is long, and the radiation is strong, the boiling point can be reached without 48 hours. If the water heater is not used for a long time, the water in the water tank will stay for a long time, and if the water tank is at a high temperature for a long time, it will accelerate the aging speed of the thermal insulation polyurethane. Scale is easy to form. Excessive pressure will also cause the water tank to expand and cause the water tank. damage.
Therefore, if the solar water heater is not to be used for a long time, the vacuum heat collection tube should be covered and removed when it is used again. You can also disassemble the vacuum collector first, but this method cannot be disassembled by yourself and requires the assistance of a professional engineer.
