You can start adding more in the fall. \x0d\1. There are two round plastic covers inside the water tank. When you lower them, you will see two antifreeze inlets and outlets blocked by silk plugs. \x0d\2. Generally, the top one is added inward, and the bottom one is full if it overflows. However, filling antifreeze is easy to cause air blockage. It is best to add it when the light is not strong or dim. the weather is cloudy and rainy. \x0d\The antifreeze should not be too thick. There is a nozzle under the water tank. Connect the hose to it, open the valve and pump it under pressure. \x0d\The hot water system is that the fins inside the planar collector convert the absorbed solar radiation into thermal energy, causing the temperature of the working fluid in the heat exchange tube of the collector to continuously increase. liquid densitye hot and low density of the cold liquid. The biggest feature is that through the circulation pipeline, a natural circulation of cold water from top to bottom and hot water from bottom to top is formed between the collector and the water tank. Thanks to this cycle, the water in the water tank gradually heats up. Since the working fluid in the flat collector is a low temperature resistant liquid, it can be maintained at minus 40 degrees without freezing. So even in alpine and cold areas it can operate normally all year round.
How often should solar antifreeze be replaced and on what basis?
Friendly response from Shanghai Simantai Chemical Technology Co., Ltd. :\x0d\\x0d\Strictly speaking, they are different, although the antifreeze base material used by many companies is ethylene glycol. \x0d\\x0d\But in terms of durability, solar antifreeze can withstand higher temperatureshigh, generally reaching 150°C \x0d\In terms of long-term effectiveness, solar antifreeze is an ultra-long-lasting antifreeze, while car antifreeze; The liquid is a short-acting antifreeze and is typically used for 2 years; \x0d\\x0d\ Simantai Company is a professional solar antifreeze manufacturer and can provide professional solar antifreeze.
It is recommended to replace solar antifreeze every two years. The scientific basis is that antifreeze will virtually lose its effectiveness after two years.
Antifreeze is a substance with a lower freezing point added to water to lower the freezing point of the cooling water and prevent the cooling system from freezing. The following issues should be considered during use:
1. During use, if the fluid level drops due to a leak in the cooling system, the same type of antifreeze should be addedty if this is due to; evaporation, then distilled water or fresh water should be added to the cooling system; When it is found that there is suspended solids, sediment or deterioration and odor in the cooling water, everything must be replaced and the cooling system must be cleaned.
2. Ethanol antifreeze is easily volatilized, so pay attention to fire prevention during its use. When the engine water temperature is too high, do not open the water tank cover or let the engine stall immediately to avoid sudden antifreeze splashing due to rapid temperature rise, causing injury or fire when the liquid level drops due to ethanol volatilization. 80% ethanol can be used to add an added note.
3. Ethylene glycol is an organic solvent when using it, be careful not tospill it on the surface of rubber products or paints, and be careful not to contact your skin. In case of accidental spillage, rinse immediately with clean water to avoid corrosion of parts or skin damage.
4. Different types of antifreeze cannot be mixed to avoid chemical reactions, precipitation or bubbles and reduce the effects of use; When replacing antifreeze, the cooling system should first be flushed with water. clean water, then new antifreeze and water should be added. Leftover antifreeze should be labeled with the name on the container to avoid confusion.
5. Due to different proportions and ingredients during preparation, different types of antifreeze have different freezing points. At this point, they should be selected based on local temperature conditions. Generally, the freezing point of antifreezeshould be 10°C to 15°C lower than the local minimum temperature to prevent antifreeze failure.
