“Solar plus medium” refers to the addition of a substance to the solar system to improve the performance of the solar system or solve certain specific problems. This medium is called "medium" and can be water, antifreeze or other special substances. In a solar system, the main role of fluid is to assist in heat transfer. In a wall-mounted solar water heater, the fluid is antifreeze. Antifreeze can help absorb heat in a solar water heater and transfer that heat to the medium, which circulates and transfers the heat to the water in the water heater.
In a split-type domestic solar water heater, the vacuum tubes are arranged horizontally. How does the heat transfer fluid circulate?
How to distinguish the fluid inlet pipe and outlet pipe on the wall mounted solar panel:
1. There are two fluid circulation pipes on the outer heat collecting plate and the upper pipe. one is theremiddle outlet (feed), connected to the middle inlet of the inner water tank (barrel). The fluid inlet (return) pipe under the heat collector plate is connected to the fluid outlet of the inner water tank. This forms an average circulation.
2. There are 4 pipe connections at the bottom of the inner water tank, all of which are marked. One of the two remaining pipes is for cold water (tap water, supplemental water) and the other is the hot water outlet.
The split solar tube has not one, but several. One part is a hot medium tube and the other part is a cold medium tube. The fluid in the heat transfer fluid tube uses sunlight to heat the fluid, then exchanges heat with the water during the rising process. After heat exchange, the fluid temperature also decreases, and then uses another tube of fluid to flow. is There is a phenomenon in nature which is the mountaineduction of heat and the fall of cold, called the siphon principle in written language. Split solar support uses this principle to circulate and requires no other energy for assistance.
