Low temperature heating and high temperature cooling: embedded water based surface heating and cooling systems.

Author(s) : BABIAK J., OLESEN B. W., PETRÁS D.

Type of monograph: Book, Guide/Handbook

Summary

This guidebook describes the systems that use water as the heat-carrier and where the heat exchange within the conditioned space is more than 50% radiant. Radiant ceiling panels are suspended under the ceiling with heat carrier temperature relatively close to room temperature. Embedded systems insulated from the main building structure (floor, wall and ceiling) are used in all types of buildings and work with heat carriers at low temperatures for heating and relatively high temperature for cooling. Finally systems with pipes embedded in the building structure (slabs, walls), which are operated at heat carrier temperatures very close to room temperature and take advantage of the thermal storage capacity of the building structure. Using a low water supply temperature (of 25-40°C) in heating conditions and high water temperature (16-20°C) in cooling, allows the possible use of renewable energy sources. In cooling conditions it is also possible to use renewable energy sources, for example ground heat exchangers or rain water ground accumulators.
Extract from the table of contents: terminology, symbols and units; basic principles of radiant surface heating and cooling; indoor environmental conditions; system types and estimation of heating/cooling capacity; control and operation; energy sources; installation; safety; application of systems in buildings (residential buildings; offices; education facilities; sport facilities; industrial buildings; museums; other public buildings); design tools.
