4 steps.
1. Use a flat blade screwdriver to open the fill port and exhaust port.
2. Open the middle inlet button and the middle outlet button under the water tank. The liquid in the water tank will flow naturally and drain the antifreeze into the water tank.
3. Use air pump to inject gas into the fluid outlet, empty the antifreeze into the flat plate or vacuum tube by gas pressure
4. when it flows from the liquid injection port.
When filling with water, some wall-mounted solar water heaters drain the water directly without adding fluid. In order to prevent freezing, etc., a medium is added to circulate the heat. Leave enough space for inflation/release 500ml after inflation, refill appropriately every two years. Northern antifreeze is an ethylene glycol antifreeze. The heat transfer fluid with co pointngelation is selected based on different latitudes. Solar fluid should be replaced every 2 to 3 years to ensure solar energy efficiency.
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 is 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. At this point it is important to determine 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 roof. room heated to water temperature, and each empty partition 25 solar heating tubes φ58mmⅹ2 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 unitic works, it does not consume or pollute 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 temperatureu.
