Solar Collector FAQ
1. What type of Evacuated Tube Solar Collectors does JinYi Manufacture?
JinYi manufactures a number of industry-leading solar collectors. JinYi heat pipe evacuated tube solar collectors (Model: JMC) are available in 10 , 12, 15, 18, 20, 22, 24, 25 and 30 tube collectors, heat pipe solar collectors (Model: JHC) are available in 10 , 12, 15, 18, 22, 24 and 30 tube collectors as well as in 8, 10 , 12, 15, 18 and 20 U Pipe Solar Collectors (Model: JUC). Additionally, JinYi manufactures 20, 25, 30, 50 and 60 tube non-pressure solar collectors (Model: JNCV) and the very popular.
2. What are Heat pipe Evacuated Tube Solar Collectors and How do They Work?
JinYi heat pipe evacuated tube solar collectors are built with series of clear glass, vacuum sealed tubes with a special selective coating that allows solar radiation to pass through from the outside and traps it inside. This 360 degree collector design is the key principle advantage of evacuated tube solar collectors - it allows for great absorption earlier and later in the day when the sun is at odd angles for most solar collectors - leading to increased overall system efficiency and cost-effectiveness. The solar radiation then heats the copper heat pipe within the Evacuated Tube, which transfers its heat upward where it is passed to the water moving through the manifold through the specially designed condenser.
3. What are U-Pipe Solar Collectors?
JinYi U-Pipe solar collectors are a form of evacuated tube solar collector. The main difference is that where the standard evacuated tube solar collector has straight heat pipes with a condenser bulb at the top for heat transfer, U-pipe heat pipes are exactly that - a U-shaped pipe that sends cold HTF (heat transfer fluid) down one side - it is then heated within the evacuated tube - and then transferred back to the manifold up the other side of the pipe. The key advantage of U-pipe solar collectors is that they can be installed totally flat (0 degrees installation) or vertical (90 degree installation) - which no other solar collector allows.
4. What are Non-pressure type Solar Collectors?
JinYi Non-pressure are not actually solar collectors - they are actually a complete solar hot water system. Each non-pressure solar hot water system includes a direct flow evacuated tube solar collector - water is heated directly within the evacuated tube (not indirectly through a heat pipe and condensor) and an integrated Solar Hot Water Storage Tank mounted directly to the top of the solar collector, where the manifold would be on a traditional Evacuated Tube Solar Collector. Non-pressure systems are closed loop - the potable water in the storage tank is separated from the HTF by a heat exchanger, which allows for the use of glycol - this revolutionary step forward allows non-pressure systems to be used in northern, cold climates where they never could before.
5. What are Flat Plate Solar Collectors?
JinYi flat plate solar collectors are ideal for southern climates. They are designed much like a PV panel, with a flat surface, however, they are much deeper, and inside each collector are a series of copper tubes. As water passes through the collector it is heated by the available solar radiation for use in whatever application your solar hot water system is being used.
