High Pressure Split Solar Water Heaters

 High Pressure Split Solar Water Heaters  

Model: JNSP

The cold water flows into the solar water storage tank directly and is stored there. The solar collector absorbs sunlight and converts it into heat energy, thus the temperature of medium in the heat pipe becomes higher. Meanwhile, the sensors will detect the temperature in collector and water tank, and then send the data to the intelligent controller. The microcomputer system will process the data and under the condition that the temperature difference reaches the setting value, the circulation pump stats to work. So the medium in the collector is transferred into the coil in the tank which is used to exchange heat, and the cold water flows near the coil and the temperature rises. One circulation finished. Thus the temperature of water will gradually rise to the setting value by repeating the circulation process.

1) Storage water tank

Storage tank is separated from the heat collector and it is pressurized type, thus it has a very thick inner tank which is made of SUS304 or 316L stainless steel, and the thickness depends on the tank capacity. The main material used for outer tank is color steel or stainless steel. According to the circulating system, our tank can be divided into three categories which are non coil type, single copper coil type and double copper coils type. Also pressure reducing valve, check valve, magnesium bar and electric heater are all equipped with the tank to form a perfect working system in combination with the collector and working station. In addition, the specially designed structure of the water tank avoids the mixing of cold and hot water.

 1. Solar for Central Heating-Preventing Overheating

If a system has been designed to provide contribution to central heating, it will often provide much more heat in the summer than is required for hot water supply alone. In such cases it is advisable for the home to have a spa or pool that can use the heat in the summer period or a heat dissipation device be installed.

2. Metallic Components

Always wear glove when handing the various solar collector components. All efforts have been made to make the metal components safe to handle, but there may still be some sharp edges.

3. Evacuated Tubes

Be careful when handing the evacuated tubes, as they will break if knocked heavily or dropped. Wear gloves if handing any broken glass.

4. High Temperatures

With the heat pipe installed in the evacuated tube, and good sunlight, the heat pipe condenser can reach temperatures in excess of 200°C/392°F. At this temperature touching the heat pipe will result in serious burns, so please take care when ” experimenting ” with, or “demonstrating ” the evacuated tube and heat pipes .In an installed, fully plumbed system, if the pump is stopped during good sunlight, the collector header and plumbing pipe close to the manifold can reach temperatures of 160°C/320°F, and therefore caution should be taken when touching such components.
