Recovering　and　reusing　this　waste　heat　for　district　heating　is　an　effective　strategy　to　enhance　energy　efficiency　in　data　centers.　To　align　data　center　waste　heat　recovery　with　heat　consumer　demand　and　improve　energy　utilization,　a　transient　mathematical　model　of　a　data　center-integrated　heat　pump　district　heating　system　was　developed　and　validated.　A　case　study　involving　a　small　data　center　with　300　standard　racks　in　Beijing　was　conducted　to　analyze　the　system＇s　operational　and　dynamic　behavior.　The　results　show　that　hot　water　and　heating　account　for　35.70　%　and　64.30　%　of　the　total　heat　consumption,　respectively.　During　the　heating　season,　the　heating　heat　pump　unit　exhibits　a　high　heating　coefficient　of　performance　(COP),　with　a　maximum　heating　COP　of　5.27.　Under　year-round　operation,　the　COP　of　the　hot　water　heat　pump　unit　exhibited　periodic　24-h　variations.　Peak　water　consumption　occurred　from　6:00　to　9:00　and　21:00　to　24:00,　with　corresponding　heating　COP　values　of　3.87　and　4.24,　respectively.　The　proposed　system　in　addressing　the　cooling　demand　of　the　data　center　and　the　heating　and　hot　water　demands　of　the　heat　consumers,　providing　a　feasible　solution　for　improving　the　energy　utilization　efficiency　of　data　centers.
