Abstract
In a double-effect absorption chiller wherein the vapor of a refrigerant produced by a high temperature generator is supplied to a low temperature generator,for condensation, and the refrigerant liquified by condensation is supplied to a condenser,, a pipe,for supplying the refrigerant liquified in the low temperature generator,to the condenser,therethrough is provided with an orifice,and a control valve,as pressure adjusting means. A control circuit,is connected to the control valve,to hold the valve,fully open during the period form the start-up of the chiller until the load is stabilized and thereafter gradually decrease the opening degree of the valve,. Alternatively, a control valve,is mounted on the pipe,for controlling the pressure of the refrigerant so that the concentration of the absorbent (intermediate solution) in the high temperature generator because equal to the average of the concentration of the absorbent (strong solution) in the low temperature generator,and the concentration of the absorbent (weak solution) in an absorber.
