Activity of occupants and shifting system activation to use reduced Rilmenidine Purity & Documentation temperature at night. The goal on the study was to figure out the momentary specific cooling power depending on the supply water temperature (Tin), the return water temperature in the . cooling ceiling (Tout), the water mass flow in the course of regeneration (m), and also the total energy supplied for the cooling ceiling through regeneration on the phase adjust material. Convective heat flux density, radiant heat flux density, plus the heat transfer coefficient (convective, radiant) at the ceiling surface have been calculated. 2. Components and Techniques Within the analyzed case, there was unsteady heat transfer (the temperature field varies with time), and its intensity was dependent on the ambient temperature. Momentary radiant heat flux density (qr) was defined as in Equation (1): qr = C0 -2 TP 4 – TS 4 , where C0 –Stefan oltzmann continuous, C0 = five.6710-8 W/(m2 K4); TP –temperature on the non-activated surfaces, [K]; TS –surface temperature of activated panels, [K]; and 1-2 –emissivity sensitive view element [37,38]: 1-2 = exactly where 1, two –emissivity of your emitting surface and emissivity from the heat absorbing surface (for developing components: 1, two = 0.9.95), [-]; A1 , A2 –field of your emitting surface as well as the heat absorbing surface, [m2 ]; and 1-2 –view factor [-]. Whereas momentary convective heat flux density (qc) was calculated as follows [39,40]: qc = c ti – ts), exactly where c –convective heat transfer coefficient, [W/m2 K]; ti –air temperature in area, [ C]; and ts –surface temperature of thermally activated panels, [ C]. The convective heat transfer coefficient among the radiant ceiling along with the test chamber (c) was determined with Equation (4) (heating) and (5) (cooling): W/m2 (three)1-1 1 A 1 1 – two A 2 W/m(1)1-.[-](two)inside a heating mode (Ra 105 ; 1010): 0.27GrPr) four Nu c = = L LW m2 K(4)in a cooling mode (Ra 806 ; 1.509):Energies 2021, 14,4 ofNu 0.15Gr r) three c = = L L where L–characteristic dimension of radiant ceiling panel, [m]; a –thermal conductivity of air, [W/(m)]; Nu–Nusselt number, [-]; Ra–Rayleigh number, [-]; c Pr–Prandtl number, Pr = p p [-]; Gr–Grashof quantity, Gr =W m2 K(5)–thermal expansion g–gravitational acceleration, [m/s2 ]; –density of air, [kg/m3 ]; ts – ti –temperature distinction among thermally activated surface and air, [K]; and -dynamic viscosity of air, [kg/(ms)].

Thermal activation of ceiling (Qw) was performed at evening (from “start” to “stop”) as well as the power intake through regeneration (water side) was calculated as follows:quit . . ts -ti |L3 coefficient, [m/s2 ];[-];W/m(six)Qw =startqc dtWh/m(7)Characteristic equation from the cooling panel proposed by standard EN 14037 and EN 14240 [28]: qm = Km n W/m2 (eight) exactly where Km –constant from the characteristic equation, [-]; T –temperature distinction of the active surface, [K]; and n–exponent in the characteristic equation from the active surface, [-]. 2.1. Experimental Chamber The tests have been performed in an experimental chamber with dimensions four.7 4.1 three.0 m (W L H), which offered a stable partition temperature. The walls had been insulated with expanded polystyrene (thickness: 0.1 m) with the following parameters: density = 30 kg/m3 , specific heat capacity cp = 1.45 kJ/(kg), and thermal c.
