The volume of a vacuum tube is 5 L, which can hold 5 kilograms of cold water. The heat collection area of a vacuum tube is approximately 1.8*0.075≈0.162 square meters, so 20 vacuum tubes are actually 2.1 square meters. . According to the conversion rate law, 1 square meter collects The water heater can provide about 60 liters of hot water per hour, so a 20 tube solar water heater can heat 120 liters of cold water to 60 degrees Celsius per hour. There is a loss of energy, usually around 30% of the energy will be lost. Then the retained hot water is about 84 liters, and the amount of irradiation for 6 hours is 84*6 = 504 liters. The solar water heater can produce about half a ton of hot water per day. This hot water is enough for a family of 4 people.
The water storage capacity of the 58 tube 20 branch solar pipe
This is not necessarily the case. The diameter and spacing of the holes de each manufacturer are different. from a regular manufacturer for your reference: 47 tube water tank. The normal hole distance of the inner tank is 70mm, the diameter of the inner tank is 360mm, and the capacity of 18 tubes is 0.18m*0.18m*3.14*(18* 0.07 m+0.2m)=0.148 cubic meters, or 148 liters. 20 bottles make 162 liters. The normal inner hole spacing of the 58 tube water tank is 85mm, and there are also 80mm holes. Small plants generally have 75mm, and the inner diameter of the tank is generally 360mm. Calculated based on 85mm hole spacing. The 16-tube water tank is 0.18m*0.18m*3.14*(16*0.085m+0.2m)=0.158 cubic meters, which is 158 liters, which is larger than the capacity of 47 tubes and 18 tubes, and slightly smaller. than the capacity of 47 tubes and 20 tubes
How do you usually buy a solar water heater to increase thehas water content?
190 liters. According to the query on Yiyi Decoration Network, the standard water flow of 58 tubes is 9.5 kilograms. Then, the water volume of 20 58-tube domestic solar water heaters is 20 times 9.5, or 190 kilograms. water tank of this solar water heater. It is 190 liters. Solar energy is a renewable energy source, which refers to the energy of thermal radiation from the sun. Its main manifestation is often called solar rays.
Water consumption depends on the number of people, generally 40 to 60 liters for gay men and 60 to 80 liters for lesbians. Domestic water consumption is 10 to 20 liters. It varies from north to south. The hot water produced is different depending on the season. It is recommended to calculate it in spring and autumn, which is more reasonable if you have a bathtub. add 100 liters. In addition, it is equipped with an electric heater at the end.
Water consumption = number of people (man, woman) + domestic water + 100
=
