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 ener-gy 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 ex-traction 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 intro-duced.
