空调设备排热对传热、新风冷负荷的影响

Effect of Heat Emitted by Air Conditioner on Cooling Loads from Heat Conduction through Envelope and from Outdoor Air

建立了室内外热环境耦合计算模型。通过实地测量,验证了模型模拟结果的准确性。采用该模型,以某典型办公建筑群为研究对象,探讨了空调设备排热对传热冷负荷及新风冷负荷的影响。空调设备排热加大了传热冷负荷及新风冷负荷,对新风冷负荷的影响更为显著。

The model for coupled calculation of indoor and outdoor thermal environment is constructed. The accuracy of the model simulation result is validated by field measurement. Taking a typical office building cluster as research object, the influence of heat emitted by air conditioner on cooling loads from heat conduction through envelope and from outdoor air is discussed. The heat emitted by air conditioner increases the cooling loads from heat conduction through envelope and from outdoor air, and has more obvious effect on the cooling load from outdoor air.
