  • ABSORPTION CYCLE SYSTEM HAVING DUAL ABSORPTION CIRCUITS
    Publication number: 20110226004
    Abstract: An absorption cycle system utilizes an additional absorption circuit in conjunction with a traditional absorption circuit. The absorbent used in the additional absorption circuit could contain an ionic compound, or any absorbent with relatively low crystallization. Mixtures of such absorbent with water remain liquid at temperatures lower than the minimum feasible operating temperature of the traditional lithium bromide water absorbent solutions of the prior art.
