Hello, the school must select water based on the number of people using it. If there are more than 10 people, it usually uses solar energy technique, as shown below.
In addition, Air energy can also be selected, as shown below. below.
The above is my personal working experience in Hunan Jiangyue New Energy (14 years of solar and air power machine accessories wholesale) and is for reference only.
Recommended "Dr. Sun" solar energy, three warehouse models (no need for water level probes and solenoid valves), heating and hot water utilization rates are fast in rainy weather, and the after-sales service rate is also greatly reduced, saving time. It also saves electricity. This model only takes 20 to 30 minutes to heat without sunlight, while a single warehouse takes 2 to3 hours
New! Which energy projects require low investment?
The solution to slow and low hot water production from solar energy is:
Tool: Siji Muge solar water heater, household small booster pump, thick water pipe
1. Raise the height of solar power to increase the height, or use thicker upper and lower water pipes or add one. small domestic booster pump.
2. The pipeline is long and has bends, which hinders the flow of hot water and there are blockages at the inlet and outlet or at the upper and lower water pipes.
Solar cleaning tips.
When cleaning with solar energy, remove the vacuum tube and pour out the scale. You can then clean it with diluted hydrochloric acid. . It is best to wear gloves whenu cleaning (it is best to use water the day before), take it apart and wash it early the next morning, and finish it before sunrise. It's usually best to ask a professional. to wash it.
Cleaning the glass pipe should be based on the local conditions of the water source (very hard water sources are prone to scale). To determine the time interval, if there is not much tartar, it is appropriate. There is no need to clean it frequently, because the sealing ring is easily damaged when disassembling the glass tube. Careful inspection should be carried out before installation. If damaged, a new sealing ring should be replaced to ensure that after installation no water leakage.
Is there a small solar water heater to use?
The project includes solar water heaters, small power generation wind turbine and useon biomass energy.
1. Solar Water Heater: This is a new energy project with relatively low investment. The solar water heater uses solar energy to heat water without electricity or gas. It is energy efficient and environmentally friendly. suitable for households and families. Small enterprises. The payback period is short, and long-term use can save a lot of electricity bills.
2. Small wind power generation is a good choice. , can convert wind energy into electricity to power homes or small facilities with small investment, low maintenance costs and long-term stable benefits
3. Energy refers to the use of biomass (such as wood, agricultural waste, etc.) that is burned or fermented. Investing in biomass energy projects, such as biomass boilerssse or biomass fermentation gas production systems, can use the waste to produce heat or electricity to recycle resources. This type of investment in projects is relatively low and also helps reduce environmental pollution.
It is generally believed that water consumption per person per day can be calculated between 40 and 50 liters, and these data are calculated based on the southern region. For domestic solar water heaters in cold northern regions, the tap water temperature in winter is around 7°C, which is obviously not enough. Solar water heating is a one-time, long-term investment. It is best to calculate it at more than 60 liters per person. This can essentially ensure that the whole family has hot water at all water points (washing, bathing, cooking, etc.). laundry room) throughout the year. It's the best change everdomestic water heater.
1. When the weather is extremely hot and the water temperature is extremely high, you should use the water supply valve to limit the pressure and add water. After air drying for a while, the temperature inside the vacuum tube can approach 300°C. If water is added, the glass vacuum tube may explode. You should wait two hours after sunset or before sunrise the next day to add water.
2. When the temperature is not too low (7℃-5℃), after exhausting the water at night, there is still hot water left in the water heater (water in the vacuum tube), and it must be filled with water immediately. Reduce the internal water temperature of the water heater, reduce heat loss at night, and make full use of thermal energy.
3. If the temperature is particularly low, the water level in the water heater should be at mycontent above 80%. If it is cloudy, try using water from the water heater and refill it immediately.
