Hello, we are from solar power manufacturer Hainade. Whether the water temperature in the solar water tank is high or not mainly depends on the following reasons:
① There is an obstruction in front of the solar system. vacuum tube. Sunlight is blocked and the vacuum tube cannot absorb sunlight;
②The orientation and angle of solar energy are incorrect. The correct direction should be south and the angle of inclination of the collector. must be close to the local latitude angle;
③The water tank is not well insulated. The insulation performance of the water tank should be tested (measure the amount of cooling of the water tank overnight); /p>
④The hot water pipe and the cold water pipe are connected in series, so that the hot water is lost from the cold water pipe; check the pipeline and install a check valve on the main pipeline to avoidloss of hot water; water ;
⑤ Check the absorption rate of the vacuum tube;
⑥ Check the vacuum tube. Is there too much scale inside that affects the heat absorption effect of the vacuum tube?
⑦ There is a lot of dust on the vacuum tube, so the vacuum tube needs to be cleaned.
The reasons are as follows:
1 There is an obstruction in front of the water heater and the sunshine time is short; /p>
2. Water supply and drainage The valve is not closed properly;
3. The water quality is not good, and there is scale in the vacuum tube, reducing the efficiency of heat collection. ;
4. The local air pollution is serious, and there is dust on the surface of the vacuum tube, which affects heat collection
5. the water tank is exhausted, that is, there is no basic water temperature, the capacity of the water tank is small, and the water consumption isimportant.
Solutions:
1. Remove obstructions or relocate solar power;
2. Replace the water supply ball valve;
3. Clean the vacuum tube;
4. Rub the surface of the vacuum tube and the focusing grid;
5. Replace a large capacity water heater or install an electric heating system.
Detailed information:
The solar water heater is a heating device that converts solar energy into thermal energy Device that heats water from low temperature to high temperature to meet people's use of hot water in life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters based on their structural shapes. Evacuated tube solar water heaters are mainly used, accounting for 95% of the market share iinterior.
Home evacuated tube solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into thermal energy mainly relies on vacuum tubes which use the principle that hot water is used. floats and cold water sinks, causing microcirculation of water to obtain the required hot water.
