LIQUIDS USED IN WALL-MOUNTED SOLAR SYSTEMS
The efficiency of wall-mounted solar thermal systems hinges significantly on the quality of the heat transfer liquid utilized within them. This liquid serves as a vital component in transferring absorbed solar energy to heat water or air circulating through the system. The primary category of liquids employed in these systems comprises water mixed with antifreeze, designed particularly for protecting the system against freezing under low-temperature conditions.
In many conventional applications, this mixture includes propylene glycol or ethylene glycol configured with distilled water. The purpose of these additives is twofold: inhibiting the potential for ice formation during frigid conditions and subsequently improving the thermal efficiency of the liquid within the system. The selection of antifreeze is critical; for instance, propylene glycol is favored in residential applications due to its non-toxic properties.
FACTORS INFLUENCING LIQUID CHOICE
When considering which liquid to incorporate in wall-mounted solar setups, several factors must be evaluated. Firstly, the local climate plays a crucial role. Areas prone to striking temperature shifts require liquids that can withstand significant variation without compromising performance. In warmer regions, a simple mixture of water and a less concentrated antifreeze may suffice, whereas colder climates demand higher concentrations to ensure the system operates effectively.
Secondly, system design and material compatibility are paramount considerations. Different components within a solar system may react differently when exposed to various liquids. Utilizing a fluid that is corrosive can lead to the deterioration of pipes, valves, and pumps, ultimately resulting in costly repairs or replacements. Consequently, choosing a heat transfer fluid with corrosion inhibitors or one known for its compatibility with system materials becomes a necessity.
ENVIRONMENTAL CONSIDERATIONS
