Abstract
A routine of controlling the dilution cycle of an absorption chiller to determine when to initiate a dilution cycle, continue the cycle and terminate the cycle. The concentration of solution leaving the chiller's low temperature generator is calculated and the crystallization temperature of the solution is then determined. The crystallization temperature is compared to the ambient temperature and the result is used to determine whether to institute a dilution cycle, continue the cycle or terminate the cycle.
