New net of China cable industry (Yangzhou) collect heats up the solar energy of vacuum plate glass that report develops by teachers and students of college of project of Yangzhou university machinery to scored a success group a few days ago, this technology uses vacuum plate glass at buy of shrinkage fitting of solar energy collect first, compare with phase of plant of solar energy of average family expenses, cost decreased 80% , and market thermal efficiency rose double, can realize large-scale concentration at the same time heat addition.
As we have learned, because common plate glass does not have heat preservation function and cannot apply at solar energy collect, and vacuum plate glass can collect heat already can heat preservation, and compare Yu Chong argon plate glass, effect of its sound insulation is better. Collecting solar energy to go up, water heater of traditional solar energy heats up a canal to come to those who achieve solar energy change with collect of full glass vacuum, use double-barreled of inside and outside, inner tube collects heat, the space is larger between each canal, collect efficiency to sell at a discount greatly. And the buy of shrinkage fitting of solar energy collect after using vacuum plate glass, receive what can achieve solar energy entirely with change, improve market thermal efficiency greatly. The experiment shows, buy of collect shrinkage fitting can achieve this solar energy 600 tile / square metre, it is common solar energy tubal form double of buy of collect shrinkage fitting.
Current, a dimensions that group of raise old scientific research builds changes box type collect to heat up group already in river city plant of an energy facility begins the work, introduce according to this factory controller, build solar energy of plate glass of this kind of vacuum market is hot group the price makes an appointment with 200 yuan / square metre, and device of common solar energy tubal form makes an appointment with 1000 yuan / square metre, only cost is managing 80% . The bag of soft qualitative water that at the same time this device uses can have change according to scope magnitude, cost is very low also. Collect heats up solar energy of this kind of box type group, cover an area of an area small, tear open outfit is simple and easy, can replace a few units with coal, the concentration that realizes energy-saving environmental protection heat addition, have wide applied perspective.
