65KPa. In the Ngari region in the west of the Tibet Autonomous Region, the number of installed units is 200 units. This is a heating project for an office building in Gumu Municipality, at an average altitude of over 4,500 meters. an average atmospheric pressure of 65KPa. The ambient temperature in winter is below -10°C and the light is sufficient (complies with AM1.0 conditions). Flat solar collector is a device that absorbs energy from solar radiation and transfers heat to the working fluid. This is a special heat exchanger. The working fluid in the sensor exchanges heat with the distant sun.
Can liquid be added after the wall-mounted solar panel is exposed to sunlight?
How to distinguish the fluid inlet pipe and outlet pipe on the wall-mounted solar panel :
1. Exterior There are two fluid circulation pipes on the heat collector plate. That oftop is the fluid outlet (feed), which is connected to the fluid inlet of the inner water tank (barrel). The fluid inlet (return) pipe under the heat collector plate is connected to the fluid outlet of the inner water tank. This forms an average circulation.
2. There are 4 pipe connections at the bottom of the inner water tank, all of which are marked. One of the two remaining pipes is for cold water (tap water, supplemental water) and the other is the hot water outlet.
Can the wall-mounted solar panels and buckets be the same brand?
You can add liquid to the wall-mounted solar panels after they have been exposed to the sun. , but not when the sun is strong.
The thermal fluid (antifreeze) inside the solar water heater system is used as a heat transfer fluid. The thermal fluid mainly uses a propylene glycol solution. Depending on the lifespan of thesupport, it should be replaced after 2-3 years to ensure the use effect. In fact, when using the solar water heating system, liquid leakage will occur at high temperature and high pressure in summer, and it may need to be replenished at that time.
Notes on filling antifreeze:
1. Do not fill when the sun is strong, to avoid being unable to fill due to thermal shrinkage of antifreeze. The best time to refuel is in the morning before sunrise and in the afternoon after sunset.
2. During the antifreeze filling process, if the antifreeze overflows from the observation port, stop filling and refill after a few minutes. The aim is to evacuate the gas present in the water tank, the collector and the connecting pipes.
3. When adding antifreeze, a larger water basin should be connected to the ground to prevent antigel from flowing to the ground.
Wall-mounted solar panels and barrels are not the same brand.
Solar barrels of the same model but produced by different manufacturers are basically interchangeable. If you are not sure, you can take a look at a saying online: same model but produced. from different manufacturers are completely interchangeable. It can be used universally; This solar bucket can be used to store solar energy. Put it in the sun during the day and store solar energy in the bucket. If needed, the solar energy in the bucket can be used for emergency purposes, although this is not technically difficult to achieve.
