What are the operating principles of flat solar collectors?

1. Sunlight shines through the transparent cover onto the heat absorber covered with an absorption layer. Most of the solar radiation is absorbed by the absorber, converted into thermal energy and transmitted to the fluid channel.

2. The cold working fluid entering from the bottom of the collector is heated by solar energy in the fluid channel and the temperature gradually increases. The heated hot working fluid carries useful thermal energy from the collector. the upper end output is stored in the water storage tank for use, which is effective energy saving.

3. As the temperature of the heat absorber increases, heat is lost to the environment through the transparent cover and shell, causing various heat losses in the flat solar collector.

The flat solar collector is the basic component for the use of solar heatire at low temperature. A water heater made of flat solar collector components is a flat solar water heater.

Detailed information

Advantages of flat solar collectors:

< p > 1. Particularly suitable for combination with architecture. Due to their planar structural characteristics, flat panel solar water heaters have flexible and arbitrary shapes and structures when used in combination with solar power and buildings. They are not limited by shape or size during design and can be easily integrated into building components.

2. It has high thermal efficiency. The flat solar collector is a continuous plane and the entire surface of the collector receives sunlight at the same time.

3. It has good pressure resistance performance. Since the heat absorbing plate of the flat solar collector is madeue of metal materials and the connection between the sensor and the water storage tank also uses metal parts, it can withstand the pressure of tap water and circulating pumps.

Yes. Since the copper pipe heats the water by absorbing energy from the sun and transfers the heat to heat transfer fluids in the water, such as pure water or antifreeze, the water temperature gradually increases and finally reaches the required hot water temperature. , the copper pipe is solar energy. The water heater heat exchanger converts heat from solar radiation into thermal energy through a heat conduction process, thereby increasing the water temperature.
