Реферат: It is well known that the presence of residual gas can significantly slow down the adsorption stage of heat transformation cycles. This work addresses the dynamic effect of residual air for two ways of adsorption initiation: by a change of either pressure (PI) or temperature (TI). The effect was studied for the working pairs "AQSOA FAM-Z02 – water" and "LiCl/(silica gel) – methanol" proposed for adsorption heat transformation (AHT). The residual air pressure ΔPair was varied from 0 to 5 mbar. The main finding of this study is that the PI adsorption is less sensitive to the presence of residual air than the TI adsorption. This is especially true at a low partial air pressure ΔPair. For instance, at ΔPair </= 0.5 mbar, residual air has little or no effect on the PI adsorption dynamics as compared to the TI one. A qualitative explanation of this finding is proposed. Thereby, closed AHT cycles based on the PI process are more robust and resistant against the presence of residual air that is a significant practical advantage.
