摘要
针对一个空调房间为研究对象,利用热动力特性建立动态数学模型,求解得到空调房间采用一次回风后瞬态热力学参数变化关系,并比较房间内在无内热源、有恒定内热源、变内热源和一次回风有、无能量损失的状况下温度随时间的变化规律。结果表明,空调房间设有一次性回风系统,室内温度比无回风时更容易达到平稳状态,回风量越大,达到平稳状态所需的时间越短,从而达到节能的目的。研究结果为进一步实现空调房间的空调系统风量自动调节和建筑节能研究提供了前提和依据。
In this article, the collected temperature of Beijing Area in 24 hours is regressed by the least square fitting method. With choosing an ideal air-condition room as researched target, a set of mathematical models that are used for simulating the thermodynamic characteristics of the room are developed. Based on these models, the thermodynamic parameters for the room with the simple return-air, at the situation of heating season (March) and refrigerating season (June), would be predicted either without inter-heat resource or with const and changing inter-heat resources, respectively. The results simulated have established a reasonable basis in theory for varying air volume (VAV) automatically in an air-condition system as well as its energy-saving.
