Abstract
A control system for absorption chillers which comprises a device for measuring operating state data concerning components of the main assembly of the chiller and including the liquid level of a high temperature generator and the degree of opening of a gas valve, and a fuzzy control circuit for calculating the deviation of the liquid level from a target value based on the measured operating state data, predicting a variation in the liquid level from the deviation and another item of the operating state data and calculating a control input as to the inverter frequency of an absorbent pump based on the result of prediction, whereby even when a great disturbance occurs, the liquid level of the generator can be controlled with high responsiveness to minimize the variation of the liquid level.
