Claims

[Scope of Claim for Utility Model Registration] K) A high-temperature regenerator equipped with a heating source for heating a dilute solution, and a separator that separates the dilute solution heated by the high-temperature regenerator into refrigerant vapor and an intermediate concentration solution; a high-temperature heat exchanger in which an intermediate concentration solution from the separator exchanges heat with a dilute solution flowing into the high-temperature regenerator; and an intermediate concentration solution flowing from the high-temperature heat exchanger by refrigerant vapor led from the separator. a low-temperature regenerator that heats the refrigerant and separates it into refrigerant vapor and a concentrated solution;
a condenser that condenses refrigerant vapor from the low-temperature regenerator;
The liquid refrigerant condensed by the condenser is dispersed and evaporated, and the low-pressure evaporator cools the cooling water, and the concentrated solution flowing from the low-temperature regenerator exchanges heat with the dilute solution flowing into the high-temperature heat exchanger. a low-temperature heat exchanger that is cooled by cooling; an absorber in which the concentrated solution from the low-temperature heat exchanger is sprayed and which absorbs the vapor flowing from the evaporator to become a dilute solution; a circulation pump that pumps the dilute solution into the low-temperature heat exchanger; and a flue of the heating source that heats the condensate in the low-temperature regenerator in which the refrigerant vapor is condensed and returns it to the low-temperature regenerator as refrigerant vapor. In a direct-fired dual-effect absorption refrigerator having an exhaust gas heat exchanger installed in the separator, the outlet piping of the exhaust gas heat exchanger is connected to the piping that leads the refrigerant vapor separated by the separator to the low-temperature regenerator. 1. A direct-fired dual-effect absorption refrigerating machine, characterized in that a suction device is connected to the connecting portion and a suction device for suctioning the steam in the outlet pipe is provided at the connecting portion. (2) The direct-fired dual-effect absorption refrigerator according to claim 1, wherein the suction device is a venturi.
