Abstract
A method of operating an absorption refrigeration system. The system has high- and low-pressure sections. The sections are connected by three lines and have an evaporator for subcooling the liquified refrigerant before it enters a connecting line. To enable uninterrupted transport of the weak refrigerant solution without increasing prime cost, the refrigerant vapor is fed from a subcooler into the expanded weak refrigerant solution at one or more points and a connecting line that conveys the weak refrigerant acts as an absorber. Expanded and evaporating refrigerant fluid flows through a subcooler in the high-pressure section. A condenser is in a line that conveys the weak refrigerant solution. The exit from the subcooler communicates through another line downstream of an expansion valve with a line that conveys the weak refrigerant solution and acts accordingly as an uncooled absorber.
