In the area south of the Yangtze River,-10℃ non-freezing antifreeze should be selected.
In the area north of the Yangtze River, antifreeze that does not freeze at -20℃ should be selected.
In the area north of the Yellow River, antifreeze that does not freeze at -30℃ should be selected.
Ensure that the system will not freeze in winter.
Pure water is also used as heat transfer medium in Yunnan and other places.
Question 2: What is the dielectric in the solar water heater? The dielectric in the solar water heater is antifreeze;
Generally, it is "ethylene glycol+water+other inorganic salts to adjust the freezing point" or "propylene glycol+water+other inorganic salts to adjust the freezing point"
Heat transfer media with different freezing points are selected according to different latitudes to prevent freezing. In the area south of the Yangtze River,-10℃ non-freezing antifreeze should be selected. In the area north of the Yangtze River, antifreeze that does not freeze at -20℃ should be selected. In the area north of the Yellow River, antifreeze that does not freeze at -30℃ should be selected. Ensure that the system will not freeze in winter. Pure water is also used as heat transfer medium in Yunnan and other places.
Question 3: What is a wall-mounted solar medium and how to add it if you add it yourself? I think if it's less, just add some antifreeze.
Question 4: How to add heat conducting medium to flat solar energy and open the plastic cover beside the water tank?
Unscrew the nut of the water tank filler, remember to unscrew both of them, and use a socket wrench to screw them back.
Open the plastic sealing ring and you can see the space between the inner container and the outer jacket.
Use a filling funnel to fill the protective layer with antifreeze from the upper hole.
After the antifreeze flows out from the observation port below, stop adding liquid.
Add it later until it overflows.
Restore the sealing sleeve and nut to the original state, cover the plastic sealing cover and finish the work.
Question 5: What is a solar medium? If you need to replenish the liquid, use the stock solution, and the mixed solution may have problems such as reflection or crystallization. Huang Ming service engineer
Question 6: What is the solar medium? Usually antifreeze. Just add the same type of antifreeze. Hope to adopt.
Question 7: What does the medium inlet of solar water heater mean? The medium of solar water heater is water, which is the water inlet.
Question 8: How to add medium to wall-mounted solar energy? I think it's good to add some antifreeze if it's missing.
