Solar heating is indeed relatively simple to understand, but it is more complicated in the implementation process. Regarding the basic principle of solar heating: that is, when using a vacuum tube collector or a flat plate collector, two factors determine the size of the water tank. One is the type of equipment to use on the heating side. , and the other is the extremely low temperature outside at night in your area. How many degrees Celsius? Or air source heat pumps or gas boilers etc., but the cost is a bit too high and not worth it. If the project is relatively large, you may consider it. It can guarantee the heating effect day and night. The basic design principles and methods are: using the veranda for direct heating by sunlight in the morning; use solar hot water thermal storage for heating the apafternoon and night.
Eight partitions are made of steel and each partition is equipped with 25 solar heating pipes φ58 mmⅹ2 meters long. It is equipped with a total of 200 pipelines, water storage tanks and hot and cold water circulation systems. When the geothermal heat pump is operating, it does not consume or pollute water. It does not require a boiler, cooling tower or place to store fuel waste. It has significant environmental benefits. The power consumption of the geothermal heat pump is incredible. I installed a water tank to store 5 tons of water and 500 1.8 meter solar tubes in 2011. The indoor temperature was 12 degrees Celsius during the day and 6 degrees Celsius at night. . After using it for 23 days, the electricity bill cost 2,348 yuan.
This problem can be addressed at the regional level. For example, areas where the temperatureminimum temperature in winter is greater than minus 10 degrees can be considered, and other heating equipment can be used as a supplement to avoid the need for heating in cloudy and snowy weather in winter. The initial investment is significant and. the government may consider subsidies. When the sun is high, at least 50 square meters of collector tubes are required. This only represents an area of 5 hours. In addition, when sunlight is insufficient and energy storage is used at night, a conservative area of 150 square meters is required. An insulated water tank of at least 2 to 3 tons is completely acceptable. The current key problem is the long-term non-mitigation of the solar system. The lifespan of ordinary metal plates is 5 years, and the best glass vacuum tubes are on the rise. at 20 years. It is recommended to pay attention to new ceramic solar collectors with highyield. Ceramic solar collectors guaranteed for at least 50 years.
Can solar water heaters be installed indoors?
Operate heating equipment (note that you need a larger model). However, due to the cold winter and lack of sunlight at night, you need to use external power to heat solar water. heating, but during the day it uses solar thermal energy to provide heating and can also store 100 square meters of rural houses. If a 100 square meter house in a rural area is heated by solar hot water circulation, it must be equipped. with 300 vacuum tubes with a diameter of 58 mm and a length of 1800 mm. Even so, the guarantee rate of solar energy can only reach more than 70%, and the remaining 30% depends on auxiliary energy. For example, solar heating of 100 square meters of houses in rural areas does not est no longer a problem in winter.
The bottom line is that solar heating requires the design and implementation of system engineering, just like a greenhouse capable of producing four-season vegetables in winter, in order to ensure the heating effect day and night. The basic design principle always depends on the installation environment of your rural house, especially the roof of the house. To this One point is to consider whether it is a pointed roof or a flat roof. If it is a pointed roof, the installation area of the solar collector is not enough, which will result in eight steel partitions on the water temperature heated room, and each partition is made of tubes solar heating φ58 mmⅹ2 25 meters long. It is equipped with a total of 200 pipelines, water storage tanks and hot and cold water circulation systems.
When the geothermal heat pump unit is operating, it will notconsumes or pollutes water. It does not require a boiler, cooling tower or place to store waste fuel. It has significant environmental benefits. The power consumption of geothermal heat pumps can also be reduced by 40% compared to air source heat pumps. The hot water storage tank is insulated. Heating water is not difficult. Think about what it would be like without insulation, or just use a concrete water tank for open storage. Can solar heating keep a cubic meter of water at 50 degrees Celsius per day? Whole house heating can be achieved if the normal water temperature is less than 100 degrees, and solar hot water can be good if it can reach 80 degrees or more. If the direction is poor or the lighting duration is short, it will be more difficult to do this. reach the ideal water temperature.
I have hereinformation that is also installed in glass, I don't know if it is similar to yours. If the orientation is correct and the impact is not significant, the installation direction is 10 to 20 degrees southwest. You should know that solar energy relies on sunlight, ultraviolet rays and infrared rays to absorb heat. If it is installed indoors and the light is not strong, it will not be useful in winter.
