This paper proposes a dedicated outdoor air system (DOAS) with thermoelectric module radiant cooling panels (TEM-RCP). The DOAS involves the concept of a decoupled system with a parallel sensible cooling unit. This concept implies decoupling of ventilation and air-conditioning functions. The DOAS treats latent loads from outside air intake as a 100 % OA ventilation system. Additionally, a parallel sensible cooling unit, such as ceiling radiant cooling panel (CRCP), generally removes sensible loads.

The aim of this case study is to investigate an integrated heating/cooling system performance in central Europe climate conditions. The possibility of a reliable application of radiant low-temperature heating/ high-temperature cooling ceiling system with capillary mats is discussed. ESP-r, an energy performance simulation program, was used for this purpose. Three types of the buildings are taken into account: a residential building, an office building with small offices and an office building with open space offices. Each of them represents a different operating pattern.
Heating and cooling of buildings may be done by water based radiant systems, where pipes areembedded in the concrete slabs between each storey. Hundreds of buildings with such systems arenow being constructed or are in operation in Europe.Because these types of systems are using the building mass for heating and cooling it is oftenquestioned how the systems should be controlled and operated. The present paper presents aparametric study of different control and operation concepts for both cooling (summer) and heating(winter) periods.
The objective of this paper is to analyse if Radiant Cooling Ceiling (RCC) has the potential to providebetter comfort and energy consumption in prefabricated buildings by comparison with conventionalsystems installed on this structures. Another purpose of this paper is to investigate the risk ofcondensation on the ceiling panel and finding the solution to prevent this. A building energy simulationcode called Trnsys was used to simulate the system and to analyse different characteristics of theRCC and of the indoor space.
