 Abstract:

This paper shows how the use of the numerical modelling method of the radiant heat flux depending on the absorption and reflection coefficients and the energy transmission degree can optimise a ceramic radiant panel heating system for an industrial hall with geometrical dimensions of 80´30´8 m and heat demand of 277.3 kW using Systema software. The optimal location of the 14 ceramic panels obtained through modelling is selected so that by controlled conducting of the heat flux of 1.03 W/m2 emitted by the radiant panels towards the working area can ensure adequate comfort. The heating system configuration flexibility enables both changing the location of radiant panels and the heat flux orientation. Thus, the operative temperature to the outdoor walls resulted in the range 19.2-19.7 °C, and the uniform operative temperature in the working area is equal to 22.6 °C in accordance with the international standards ISO 7730 and ASHRAE 55. Additionally, the expected mark (EM) value of 0.04 calculated as the ratio between the predicted mean vote (PMV) and the predicted percent dissatisfied (PPD) indexes indicates the assurance of adequate thermal comfort conditions, according to the same standards. The estimated energy consumption and operating costs show that liquefied petroleum gas utilisation is clearly the best solution with respect to methane and diesel for fuel supply of the modelled radiant heating system.
