Advantages and disadvantages of wall-mounted solar water heaters for balconies 21. What is the working principle of solar water heaters. It mainly involves three processes: heat absorption, circulation and insulation.
2. Heat absorption. Firstly, the solar water heater passes through a special coating on the collector surface to well absorb solar radiation and prevent the emission of long-wave radiant heat. a hole. The heat pipe converts absorbed solar radiation into thermal energy, which can heat cold water.
3. Circulation, solar water heater reuses the characteristics of cold water being denser than hot water, cold water flows and hot water rises, forming cold water in the vacuum tube from top to bottom and heat The natural circulation of water from bottom to top makes the temperature gradually increasewater throughout the water tank and reach a certain temperature.
4. Insulation, then insulate the hot water through the outer tank, the polyurethane foam layer and the stainless steel inner tank of the insulated water tank. It will be convenient for everyone to use hot water at night.
Can solar water heaters be used in winter?
1. Can solar water heaters be used in winter? As shown in the working principle of solar water heater above, the answer to this question is yes. But if you want to use solar water heater better in winter, there are some skills. The principle is that the lower the temperature, the more water must be released several times and in small quantities, relying on the water temperature to increase the temperature of the pipes and prevent the pipes from freezing and close up.
2. If the temperature is not very low, turn on the hot water immediately after using it that night, this will reduce heat loss that night and make full use of heat energy.
3. If the temperature is relatively low, get into the water after getting up the next day. And put a small amount of water before bed or the next morning to prevent pipes from freezing and clogging.
4. If the sunlight is not strong that day and it is raining or snowing, you can add half a tank of water or more than half a tank of water according to actual needs.
5. If the water consumption is large, consider starting the electric heating of the solar water heater or putting the water from the solar water heater into the electric water heater to heat it slightly .
6. When the temperature is below 0 degrees Celsius, be sure to activate the anti-freeze device. After aIf you have mastered these tips, you will be able to use your solar water heater well in winter.
Safety Tips
1. When taking a bath, if the water in the solar water heater is used up and the person does not has not rinsed, you can apply cold water for a few minutes, use the principle that cold water flows and hot water floats, and the hot water in the vacuum tube is discharged and you can take a bath.
2. Use the principle of ARaison: if after taking a shower, there is still some hot water left in the Huangming brand solar water heater of Huangming company, and if you apply cold water for a few minutes, hot water can be used to wash an additional person. (Each vacuum tube produces 6.5 liters or 8 liters of hot water)
3. Determine the amount of water supplied based on the weather forecast to obtain a water temperaturemore satisfactory: if it is sunny, the water can be filled, and on a cloudy or cloudy day If it rains, the water in the tank will be filled with half a tank of water; if it rains, the original water will be retained and no cold water will be poured.
4. After taking a shower at night, if there is still half of the hot water near 70°C in the water heater tank, in order to avoid loss of excessive heat (the less water, the faster the heat loss), you should also adjust the temperature depending on the weather. The forecast determines the amount of water supplied. On clear days, the water supply will be full, and on cloudy and rainy days, 2/3 of the water supply will be. completed.
5. Hot and cold water adjustment: The steps for adjusting the water temperature of the Huangming brand solar water heater are as follows: open d 'first the cold water valve, adjust the cold water flow of mappropriate temperature, then open the hot water valve to adjust until the desired bath temperature is achieved. Additionally, the amount of cold water can be determined empirically based on weather conditions. Be careful not to point the nozzle towards the human body to avoid burns.
6. Wind resistance measurements: Since the parts of Huangming brand solar water heater are reliably connected, the wind resistance performance mainly depends on its installation method and fixation. Currently, the solar water heater is fixed. with 8# galvanized iron wire and extended expansion bolts, forming a figure-eight shape at the front and rear, with good wind resistance. In addition, in areas with strong winds such as coastal areas, the effect will be better if the support is used. the structure is modified, or the back plate is removed and secured with steel strands used to secure the potelephone rates.
