According to the national standard GB19141-2011, it is between 120 L and 150 L.
The capacity of the tube itself is about 36 L.
Au total, that's around 150L.
But you can't use the water from the vacuum tube.
Solar energy capacity
In northern regions, winters are harsh and temperatures are low. If protective measures are not taken for solar water heaters, the pipes may freeze and become clogged, which will affect their use. ; more seriously, it could cause the pipeline to rupture and cause damage to the building. Therefore, in winter, especially in northern regions, more attention should be paid to the maintenance of solar water heaters to ensure that the water heaters survive the winter safely.
First, check the solar water heater to see if the pipes are insulated and the insulation installations are intact. GoldIf the temperature is below 0 degrees, it is best to use the water from the solar water heater several times a day in small quantities, especially before going to bed and after getting up. Put a small amount of water to make water into the water heater. pipe flow rate and rely on water temperature to increase pipe temperature; or when going out, connect a basin under the water outlet, loosen the valve and let it drain slowly. The flow of water in the pipe will prevent freezing and blockage if; the pipe is not installed with a reverse slope, you can drain the water from the water heater after running out of water. Additionally, installing electric heating tape on the pipeline is the most effective way to prevent freezing.
Is there a relationship between the capacity of the solar water tank and the number of vacuum tubes? Is it true that pipes number 18 are 180 liters, pipes number 20 are 200 liters, etc.? ?
For 3 people, it is more appropriate to buy about 150 liters (18-20 pipes). Generally this can be calculated as 60-80 liters per person depending on water consumption.
The capacity of a general 16 branch water tank is only about 130 liters, which is more suitable for two people in winter, it is smaller for three people.
There is a certain proportional relationship between the capacity of the water tank and the number of vacuum tubes, but each tube does not correspond to 10 L of water. The number of vacuum tubes directly determines the heat collection area of the solar water heater. At the same time, when vacuum tubes of different quality and efficiency have the same heat collection area, the corresponding water tank capacities are also different. released by various manufacturers are all in the water tank. Assuming that the capacity is determined, the number of tubess vacuum and the efficiency of vacuum tubes are taken into account, and the final shape is finalized after repeated testing.
