T to determine the handle technique of your program in actual conditions. Figures 12 and 13 show the heat transfer coefficients (k , r) and heat flux density of your thermally activated ceiling (qk , qr) by introducing discrete steady states to get a full test cycle (24 h) and separating the period of regeneration of your phase alter material as well as the period of occurrence of the cooling load. The figures were made determined by the results collected for variants Ia IIb. The parameters describing the convective heat transfer (qk , k) had been presented according to the temOzagrel Cancer perature difference amongst the surface from the ceiling with PCM along with the air. Parameters describing radiative heat transfer (qr , r) were presented as a D-?Glucosamic acid Purity & Documentation function in the temperature difference between the PCM ceiling surface plus the other thermally non-activated surfaces. The range of the temperature difference shown inside the figures corresponds towards the operating circumstances with the program for the analyzed variants. Larger temperature differences were obtained in the course of the regeneration time.2021, 14, x FOR PEER Overview PEER Critique Energies 2021, 14, x FOR13 of13 ofshown Energies 2021, 14,in the figures corresponds for the operating circumstances with the method forthe program for the anashown inside the figures corresponds to the operating situations in the ana13 of 16 lyzed variants.
