It takes several hours to half a day for the balcony wall-mounted solar panel to conduct heat to the water tank after adding fluid. According to relevant public information, after the middle of the balcony wall-mounted solar equipment absorbs solar energy, it takes a certain time to transfer it to the water tank. This process must overcome interference and resistance to heat transfer caused by factors such as air and materials, so it takes some time. The intensity and duration of sunlight are important factors that affect the heat transfer efficiency of solar equipment. In case of bad weather or insufficient sunlight, the heating effect of sunlight on the equipment will be reduced, thereby affecting the speed and efficiency of heat transfer. The distance between the water tank and the balcony wall-mounted solar device will also affectthe rate of heat transfer. If the water tank is too far away, heat transfer will take longer and longer pipes, which will slow down heat transfer.
How to add a thermal conductive medium to flat solar panels
JinkoSolar, Midea Group and Macro.
1. JinkoSolar is a manufacturer specializing in solar cells, components and system solutions, with a good reputation in the solar field.
2. Midea Group: Midea Group is a comprehensive home appliance manufacturer, including Midea, Little Swan and other brands. The heat transfer liquid used in its solar water heating products is also highly recognized by consumers.
3. Macro: Macro is a company specializing in the production and manufacturing of solar water heaters and accessories. It also has rich experience in the field of thermal fluids. The solar heat transfer fluid,also called heat transfer fluid of solar water heaters, is used to transfer heat from the solar absorption plate to the water tank.
We can connect it in series and add the heat conducting medium to the flat sun.
Connect the solar hot water outlet to the water inlet of the water heater. This way, when using solar power, all water must go through the water heater first. When the water temperature in the solar water tank can meet our needs, the hot water will be directly available to users through the water heater. If the solar water temperature is low, you can turn on the electric water heater to heat it and then use it.
The advantage of this method is that hot water will be available as soon as it is turned on. Solar water tanks have a large capacity. If all heating takes a long time, electricity will be consumed and the water maynot be fully used, which will result in wasted energy and time. If connected in series with an electric water heater, the water tank capacity of the electric water heater is small and the heating energy consumption is low.
Detailed information:
Compared with ordinary flat plate solar water heaters, water heaters Plate heat pipes Solar water heaters have the following advantages:
① The heat pipes of plate heat pipe solar water heaters are generally gravity thermosyphons. They have the characteristics of unidirectional thermal conductivity, i.e. heat can only be directed from the evaporation section to the condensation section, and it cannot be directed from the condensation section to the evaporation section. Therefore, in the northern regions, when the outside temperature is belowthe temperature inside the water tank at night, heat will not be lost from the water tank to the outside via the heat pipe.Access the local environment;
② The heat pipe working fluid can use antifreeze working fluid. In cold northern regions, it can avoid freezing and heat pipe rupture due to low temperature on winter nights;
③Each heat pipe Heat pipes are independent heat pipe components. If just one heat pipe is bent it can be replaced and has nothing to do with the system. Therefore, installation and maintenance are more convenient and convenient. the lifespan is long. The downside to heat pipe flat panel solar water heaters is that they are more expensive. In order to improve heat transfer efficiency, it is better to use heat pipes and fins made of copper, aluminum and other non-ferrous metals, which increases manufacturing costs. If the steel at carbone is used as the material for heat pipes and fins, the price can be similar to ordinary flat panel solar water heaters.
