Promote the application of renewable energy buildings, that is, increase the proportion of renewable energy such as solar energy, shallow geothermal energy, and biomass energy in building energy use. Taking the use of shallow geothermal energy (within 100 meters of land surface) as an example, geothermal energy can be “carried†to the heating of the room air through technical means, which can save 50% energy than heating oil boilers and 70% energy savings than electric heating. Tianma Student Apartment of Hunan University acquired thermal energy from underground 60 meters to carry out large-scale application and realized the supply of domestic hot water to more than 4,000 students.
Low porosity clay bricks are made of ruby, mullite and combined clay as the main raw materials, molded under high pressure and sintered at high temperature. The product has excellent high temperature Physical properties and chemical corrosion resistance. Low porosity clay bricks have good stability, the degree of erosion does not occur sudden change, than ordinary clay bricks use cycle increased 2-3 times. Thermal conductivity, specific heat and solubility, respectively, than ordinary clay bricks 2 times higher than 10% and 40%, heat storage capacity than ordinary clay bricks higher than 50% -60%, can improve the thermal efficiency of the kiln.
