AB - In order to solve the problem under the exterior wall of a building, the  author proposes a thermodynamic model for HVAC. Scientific and technological  progress has promoted social development, under the new development  situation, people have higher requirements for living environment. In  architectural design, residential environment design is the key content,  especially the design of indoor temperature control system. With the  continuous promotion of the national sustainable development strategy, the  current architectural design pays more at­tention the green design concept,  and the HVAC design is the key design content in realizing the green  architectural design. In order to make HVAC design more scientific and  reasonable, the author studied the concept that HVAC design needs to follow  from the perspective of green buildings, and analyzed the specific  ap­plication methods of HVAC design technology. The experimental results  indicate that the building envelope parameters have a great impact on the  building thermodynamic performance, and the annual cooling and heating  loads of buildings should be comprehensively considered, reasonably  determine the building envelope parameters. The building load has a low  support value, so only low quality energy can meet the building load demand,  when selecting the HVAC system, consider the matching of energy quality, try  to introduce low grade energy, and improve energy utilization efficiency.
