LED to help create a conservation oriented campus in Tianjin

Geothermal well, ground source heat pump, water source heat pump, gas boiler, solar energy...... A variety of energy-saving, water-saving, comprehensive utilization of resources, such as technology, technology and equipment, now in the new campus of Tianjin University of science and technology can be seen everywhere.

More than 1500 light LED lighting lamps and more than 2000 lights of LED indoor lighting throughout the campus, with independent intellectual property rights LED semiconductor lighting materials technology, which is currently the world's largest commercial semiconductor lighting demonstration project, annual savings of 1 million 300 thousand kwh of electricity, equivalent to 500 households a year total electricity. Student apartment roof installed 1500 square meters of glass vacuum tube heat collector system, the use of solar energy to supply hot water and shower water canteen students, only this one year for the school to save more than 100 yuan.

In the process of building a new campus, the school attaches great importance to the use of renewable resources. In the new campus playground, tennis courts and volleyball courts, there are 588 shallow soil heat exchanger wells, through which, the school to achieve a ground source heat pump system and ground heat exchanger. In winter heating, the heat pump system to the surface in the heat "take out" the supply of indoor heating, and to the underground storage; the use of air conditioning in the summer, the indoor heat "take out" release to the surface, to the underground storage of heat for heating in winter. At present, the project has been through debugging, this winter is about to put into operation, is expected to save more than 100 yuan per year.

According to reports, based on the integrated utilization of energy, water, construction of the school system has also been demonstrated by experts, will be implemented this year, this system includes direct drinking water, collection and utilization of comprehensive utilization of reclaimed water, rainwater and water conservation and the ecological restoration without power. Tianjin will be through innovation fund special funds to support the school's water system construction.

University is a large energy consumption, therefore, to create a conservation oriented ecological campus, the school should be energy saving throughout the whole process. "Zhang Hongwei said," through the use of new technology, improve resource utilization, maximize the benefits, the school building has become a set of personnel training, resource saving and environment friendly and ecological benign cycle as one of the exemplary community.
