Summary

The novel adsorbent of ammonia based on binary salt system BaCl2 + BaBr2 inside vermiculite pores was intently designed for adsorption cooling cycle specialized for ice-making. On the base of analysis of the working conditions of the cycle the requirement for the optimal adsorbent was formulated in terms of the equilibrium temperature of reaction between the salt and ammonia and the real composite adsorbent (BaCl2 + BaBr2)/vermiculite with required properties was prepared. The dynamics of ammonia adsorption on the composite was studied by a Large Temperature Jump method under working conditions of the ice-making cycle. The maximum cooling power W(o) realized at t --> 0 was estimated as 1.2 kW/kg. The composite allows the production of 2 kg/(kg h) of ice. Such a good performance demonstrates an advantage of the target-oriented design of the composite adsorbent with predetermined properties matching the particular conditions of the cooling cycle.
