2.1 Building energy simulation software 43 In EnergyPlus, the scheme of calculations, shown in Fig. 2.3, is based on a series of elements connected by air or water loops. Each fluid circuit has supply and demand sides. The Gauss-Seidell scheme is used to integrate, control and solve mass and energy balance equations for all loops. Fig. 2.3: Simultaneous solution scheme used in EnergyPlus A concept of heat and mass transfer modelling in EnergyPlus is based on the following balancing equation for each analyzed zone. q � q CONV IL + qCONV−S + qMIX + qINF + qSYS �� where: q CONV −S q MIX INF = = q − , (2.1) q Zi CONV − IL dθZi = CZi – energy stored in air inside control volume, dt = ∑ = i nl i= 1 q L i , – convective internal heat loads, ∑ ( ) = i ns hi Ai θ Si −θ Zi – convective heat transfer from the internal surfaces, i= 1 ∑ ( ) = i nz G& ic p θ zj −θ Zi – heat transfer between zones due to air mixing, i= 1 INF cp ( θe − Zi ) ( θ − ) q = G θ & – heat transfer due to infiltration, q = G c θ & – energy provided to the zone by the ventilation system, SYS SUP p SUP ZONE Zi C Zi – heat capacitance of air inside zone, θ – temperature of air inside zone, Zi t – time, nl – number of heat loads, q L, i – internal heat load by convection, ns – number of heat transfer surfaces, h – convective heat transfer coefficient, i A – heat transfer surface area, i SYSTEM < FLUID LOOPS > PLANT
