Dynamic thermal modelling of PV performance and effect of heat capacity …
WebDec 1, 2024 · Heat capacity is one of the PV module parameters and a necessary part of the transient thermal analyses. However, there are no studies on the measurement of the heat capacity of PV modules in literature. The transient thermal models developed for PV modules, most of the time, consider a fixed value for heat capacity [ [11], [12], [13], [14] ]. WebApr 4, 2024 · Usually that involves adding 10 to 20% to the result of your calculations, as shown below: Multiply to calculate BTUs per hour: Pounds/hour X specific heat X ΔT = BTUs per hour Convert BTUs to tons: BTUs per hour / 12,000 = Tons per hour. Add a safety factor of 10% to 20%: Tons per hour x 1.2 (safety factor) = Chiller size in tons shands urology gainesville
