Work Principle

A very simple way of Heat Exchange, making use of gravity ,the thermosyphon system. The principle of the thermosyphon system is that cold water has a higher specific density than warm water, and so being heavier will sink down. Therefore, the collector is always mounted below the water storage tank, so that cold water from the tank reaches the collector via a descending water pipe. If the collector heats up the water, the water rises again and reaches the tank through an ascending water pipe at the upper end of the collector. The cycle of tank–water pipe–collector ensures the water is heated up until it achieves an equilibrium temperature. The consumer can then make use of the hot water from the top of the tank, with any water used being replaced by cold water at the bottom. The collector then heats up the cold water again. Due to higher temperature differences at higher solar irradiances, warm water rises faster than it does at lower irradiances. Therefore, the circulation of water adapts itself almost perfectly to the level of solar irradiance. A thermosyphon system’s storage tank must be positioned well above the collector, otherwise the cycle can run backwards during the night and all the water will cool down.



Pressurized flat panel solar water heater features:

1.Patterned temper glass or low iron temper glass (4mm thickness) offers the best capability of durability, strength.

2.Blue sputtering coating has high absorption rate and heating efficiency.

3.Since there are no adhesive or mechanical joints, nothing will deteriorate with usage and high temperature.

4.Special Anodized aluminum alloy frame to ensure handsome appearance and can accept high pressure without leakage.
