Energy analysis based on dynamic simulation of industrial heating by radiant modules with condensing unit

Industrial buildings are characterized by large dimension of the air-conditioned volume with respect to the occupied volume. This is mainly due to great heights and areas. Usually, industrial buildings are heated only. Radiant heating systems are particularly suitable for this kind of buildings, furthermore air systems are largely used as well. This paper reports on the dynamic simulation of a real industrial building coupled with an innovative condensing radiant heating system. A Trnsys type is modified in order to simulate the behavior of the high temperature condensing system. Energy performance is compared to that of two more traditional plants such as warm air heater and low temperature radiant floor coupled to condensing boiler. A comparison from the indoor thermal comfort point of view is reported as well.
