Adsorption Heat Pump Coatings Investigation
In this study, a theoretical investigation was made to predict the performances of zeolite Y and SAPO-34 coatings for an adsorption cooling system operated by waste heat, under various conditions. A mathematical model developed and tested previously for coatings of A and X type zeolites on various substrates was used for this purpose. This dataset includes the data related to the modeling results of the heat pump system, comprising temperature and concentration distributions and heat pump cycle time.
SAPO-34 generally provided relatively high maximum cooling power, owing to its high water sorption capacity coupled with the relatively low regeneration temperature. However, mass transfer resistances became quite significant at relatively high coating thicknesses, originating from the rather slow water diffusion in this zeolite. Utilizing a relatively low desorption temperature of 100 degrees C, instead of 150 degrees C, favored the relative performance of SAPO-34 coatings. The strong temperature dependence of water diffusion in zeolite Y reduced the performance of this material. The enhancement of the adsorption temperature from 25 degrees C to 60 degrees C resulted in improved performances for NaY coatings. When enhanced diffusivity values were used in the calculations, to represent coatings with more open texture, the cooling power increased notably for both zeolites.
