The principle of wall-mounted solar energy: the solar panel collector absorbs heat energy, and the hot water circulates via the hot and cold circulation method through the conduit into the water storage tank. water
The hot water system is a flat plate collector. The fins inside the radiator convert the absorbed solar radiation into thermal energy, causing a continuous increase in the temperature of the working fluid in the heat exchange tube of the collector. low density of hot liquid and high density of cold liquid, 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 stay at minus 40 degrees withouts freeze. So even in alpine and cold areas it can operate normally all year round.
Detailed informationAdvantages
1. Save space, the collector is separated from the water storage tank, solving the installation problems of high-rise users;
2.The collector It can be hung on the balcony or on the wall exterior to reduce wind resistance and look beautiful;
3. The collector does not directly contact the water in the pipe, but conducts thermal energy to the condensing end. through the conductive liquid, thermal energy is transferred from the condensing end to the scale-free conduit;
4. The transfer fluid is a professional antifreeze agent and can be used normally in low temperature conditions. heat in two minutes under the sun;

5. Polyurethane foam is used as an insulating layer in the water tank, whichi has better insulation performance;
6. The water storage tank is equipped with an auxiliary electric heating system, which can turn on the auxiliary system even when there is insufficient sunlight. The water heater can also be used normally;
7. composed of an internal enamel tank structure, which isolates water and electricity, making it safe and reliable;
8. The whole system is used under pressure and will not be so if the water storage tank is empty due to lack of water, it will be safer to use.
