中小型商业建筑通常使用屋顶单元 (RTU) 来提供室内舒适度。这些应用的特点通常是舒适度的显着空间变化，这是由于恒温器放置不良和 RTU 协调不良导致能源和需求成本高以及边际舒适度高。需要能够评估此类应用的能源和舒适性能的工具，以便可以在能源和舒适度方面评估改进的 RTU 协调和控制的好处，并制定适当的实时策略。在本文中，我们讨论了一种生成和耦合建筑围护结构和室内空气动力学的易处理降阶模型的方法。对采用四个屋顶单元的典型坐下餐厅进行耦合模型的总体评估。可以从现场进行测量来验证模型。 (C) 2015 Elsevier Ltd. 保留所有权利。
Small-to-moderate sized commercial buildings commonly use rooftop units (RTUs) to provide indoor comfort. These applications are often characterized by significant spatial variations in comfort due to poor thermostat placement and poor coordination of RTUs leading to high energy and demand costs and marginal comfort. Tools are needed that can assess both energy and comfort performance for these types of applications so that the benefits of improved RTU coordination and control can be evaluated in terms of energy and comfort and so that appropriate real-time strategies can be developed. In this paper we discuss a method for generating and coupling tractable reduced order models for the building envelope and for the indoor air dynamics. Overall assessments of the coupled model are performed for a typical sit down restaurant that employs four rooftop units. Measurements are available from the site to validate the models.
