A water volume of 12-15 tons requires a 250 square meter solar collector, and the market price is around 250,000 yuan. The water consumption for bathing 30 people should be about 3 tons, and 15 tons can wash at least 150 people. If the water tank needs to be insulated, you can use solar energy to discharge water at a fixed temperature. For example, if the water is set at 58 degrees, the temperature in the water tank should be above 53 degrees. 43 degrees. The water tank will not drop below 43 degrees within 24 hours. If the water temperature is too high, use the mixer tap to adjust the water temperature.
Conventional collecting tubes, 500 pieces, 4 tons per day. The best collector tube, 500, can produce 5 tons per day. The insulation layer of the thermal water tank is mainly 5cm, and the constant temperature value is 40 degrees. If the water temperature ise 60 degrees and the outside temperature is 5 degrees, the water temperature will be 45 degrees the next morning; if the water temperature is 60 degrees and the outside temperature is minus 20 degrees, the water temperature will be 20 degrees. the next morning;
