Control of slab heating and cooling systems studied by dynamic computer simulations.

Author(s) : OLESEN B. W.

Summary

Due to high energy consumption and costs, several European countries debate if air conditioning of buildings is recommendable or should be prohibited by law. Of course air conditioning will give better control of the indoor temperature and then improve comfort and productivity. There exist, however, many examples of discomfort in air-conditioned buildings due to draught, noise and sick building syndrome. Alternatively, heating and cooling may be ensured by water-based radiant heating and cooling systems, where pipes are embedded in the concrete slabs between each storey, often combined with a ventilation system in which the amount of outside air is based on the requirements for acceptable air quality. Because these types of systems are using the building mass for heating and cooling, the type of control concept that should be used is often discussed. This paper presents a parametric study of different control concepts. The study is based on dynamic computer 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.
