New model and practice of zero-carbon solar district heating in Xizang Plateau
Year: 2024
Type: article
Abstract: The Xizang Plateau has a long and cold winter, and the reserves of conventional energy such as coal and natural gas are nearly zero, making building heating a great challenge. However, the local solar energy resources are extremely rich, so there are prerequisites for using solar energy to achieve zero-carbon heating of buildings. Aiming at the "oasis type" counties and towns on the Xizang Plateau, we explores a whole chain zero-carbon solar district heating model of "large-scale solar heat collection + large-scale water heat storage + differentiated insulation of building envelope + separate heating circuits for the north and sourth rooms". We elaborata complete set of key support technologies and methods such as large-scale solar heat collection technology and products, capacity configuration of large-scale hot water storage and efficient heat storage and extraction technology,"differentiated insulation" design method of building envelope structure, and a new double independent heating system with separate south and north pipe network circuits. The practical experience and effect of the new heating model in Xizang Plateau are also introduced.
