哈尔滨地区办公建筑夜间机械通风能耗及室内热环境分析 总被引:2,自引:0,他引:2
采用EnergyPlus软件对哈尔滨地区典型办公建筑在常规空调系统运行模式与夜间机械通风系统运行模式下的室内热环境和能耗进行了模拟。结果表明,在哈尔滨地区,白天室外最高温度高于24℃时都适合进行夜间机械通风,一共约60d,占空调运行期的72.3%;整个夏季空调运行期内,采用夜间机械通风系统该办公建筑节电量指标为1.15kWh/(m2.a),节省运行费用指标为1.02元/(m2.a);在人工制冷阶段,夜间机械通风模式下的室内热环境明显优于常规空调模式,且房间体积与表面积比越小,越有利于提高室内环境的热舒适性;当室内空气设计温度较高时,室内温度下降大,延迟人工制冷开启时间长,但是节能量未必比室内设计温度较低时高。 相似文献

This paper analyzes the potential of natural resources to improve the indoor thermal environment in Chongqing through the
statistical analysis of natural resources including solar energy, wind, water, and earth, etc. The building form, systems,
and principle of usage of natural resources are briefly analyzed through the building site decision, building form design,
and computer simulation, which will be the real reference for the design of building energy efficiency.

Realtime and precise control strategies for indoor micro-climate are increasingly needed due to the requirements of thermal comfort and energy consumption saving in recent years. In this paper, a precise control scheme with high resolution is proposed for indoor thermal regulation. Finite volume method discretization/linearization are employed to construct the state-space model of the thermal process. Proper orthogonal decomposition method is further applied for model order reduction. On this basis, a multiple model approach is used to treat the thermodynamic coupling effect and a multi-model switching model predictive control (MPC) scheme is proposed for temperature tracking. Two cases including cooling and warming scenarios are designed, respectively, for performance validation. Results show that compared with the classic MPC method, the developed method can alleviate the model mismatch problem, and facilitate an optimal control of the spatial temperature in the considered ventilation room. 相似文献
