由于高能耗和首件成本，几个欧洲国家就建筑空调是否应该被法律推荐或禁止展开了辩论。空调将更好地控制室内温度，提高舒适度和生产率。然而，由于通风、噪音和病态建筑综合症，空调建筑中存在许多不适的例子。或者，可通过循环辐射供暖和冷却系统来满足显热负荷和冷负荷，其中管道嵌入各层之间的混凝土板中。 这些系统通常与通风系统相结合，在通风系统中，外部空气量基于可接受的空气质量要求。由于这些类型的系统使用建筑体量进行加热和冷却，因此经常有人质疑应该使用什么样的控制概念。本文在动态计算机仿真的基础上，对不同的控制概念进行了参数化研究。结果表明，根据室外温度条件，结合时间控制和水温控制，将提供可接受的室内条件和低能耗。 单位:SICitation:研讨会，ASHRAE交易，第108卷，第页。2.

Due to the high energy consumption and first cost, several European countries debate if air conditioning of buildings is to be recommended or prohibited by law. Air conditioning will give better control of the indoor temperature and improve comfort and productivity. There exist, however, many examples of discomfort in air-conditioned buildings due to draft, noise, and sick building syndrome.Alternatively, sensible heating and cooling loads may be satisfied by hydronic radiant heating and cooling systems, where pipes are embedded in the concrete slabs between each story. These systems are often combined with a ventilation system, where the outside air volume is based on the requirements for acceptable air quality. Because these types of systems use the building mass for heating and cooling, it is often questioned what kind of control concept should be used. The present paper presents a parametric study of different control concepts, based on dynamic omputer simulations. The results show that a combination of time control and water temperature control according to outside temperature conditions will provide acceptable indoor conditions and low energy consumption.Units: SI
