摘要：

With　the　climate　conditions　in　Qinghai　region　and　the　characteristics　of　local　rural　buildings,　taking　Da　Qaidam　as　an　example,　this　paper　calculated　the　non-balanced　heat　transfer　coefficient　limits:　the　south　wall≤　0.62　W/(m2•K),　the　east　and　west　wall≤0.51　W/(m2•K),　the　north　wall≤　0.44　W/(m2•K).　Also,　the　time　lag,　decrement　factor,　the　net　heat　loss　and　interior　surface　fluctuation　temperatures　of　the　non-insulation,　balanced　insulation　and　non-balanced　insulation　walls　are　compared　and　analyzed　by　harmonic　response　method.　The　results　show　that　the　average　inner　surface　temperature　of　non-balanced　insulation　wall　is　higher　of　3.14　-　4.98　than　non-insulation　wall,　and　total　energy　saving　rate　reaches　up　to　74.4%.　At　the　same　time,　the　total　net　heat　loss　of　non-balanced　insulation　wall　is　less　than　that　of　the　balanced　insulation　wall,　which　meets　the　requirements　of　energy　saving　standards.　The　difference　between　the　average　inner　surface　temperature　in　different　walls　is　only　0.08,　which　is　less　than　the　value　of　0.48　and　1.81　for　balanced　insulation　wall　and　the　non-insulation　wall,　which　effectively　reduce　the　difference　of　indoor　asymmetry　radiation　temperature　and　increase　the　thermal　comfort　of　the　interior　personnel.　©　2020,　Editorial　Board　of　Acta　Energiae　Solaris　Sinica.　All　right　reserved.
