The hot water system is that the fins in the flat plate collector convert the absorbed solar radiation into heat energy, which makes the temperature of the working medium in the heat exchange tube of the collector increase continuously. Using the characteristics of low density of hot water and high density of cold liquid, a natural circulation of top-down cold water and bottom-up hot water is formed between the heat collector and the water tank through the circulation pipeline.
Through this circulation, the water in the water tank is gradually heated. Because the working medium in the flat plate collector is a low-temperature resistant liquid, it can be kept at MINUS 40 degrees without freezing. Therefore, it can operate normally all year round even in cold areas.
Expand data advantages
1, saving space, separating the heat collector from the water storage tank, and solving the installation troubles of high-level users;
2. The heat collector can be hung on the balcony or outdoor wall, which reduces wind resistance and is beautiful and generous;
3. The heat collector is not in direct contact with the water in the pipeline, but conducts the heat energy to the condensation end by conducting the liquid, and the heat energy is conducted from the condensation end to the pipeline without generating scale;
4. Conductive liquid is a professional antifreeze medium, which can be used normally at low temperature and can output heat in the sun for two minutes;
5. Polyurethane foam is used as insulation layer in the water tank, which has better insulation performance;
6. The water storage tank is equipped with an auxiliary electric heating system. In the case of insufficient sunshine, the water heater can be used normally even if the auxiliary system is turned on;
7. The water storage tank is composed of enamel liner structure, which is safe and reliable because of water and electricity isolation;
8. When the whole system is used under pressure, the water storage tank will not be burnt out due to lack of water, so it is safer to use.
