A novel plate heat exchanger absorption chiller belongs to the field of heat exchange equipment technology. It employs a two-stage low-temperature heat return system, a refrigerant plate heat exchanger, and a first-stage low-temperature heat return system connected in series and in parallel with the low-temperature heat exchanger. A dilute solution is heated by heat from the shell side and collected before entering the plate low-temperature regenerator. In the plate low-temperature regenerator, it is heated by high-temperature refrigerant vapor from the plate high-temperature regenerator, concentrating it into an intermediate concentration solution. This intermediate concentration solution is then pumped through an intermediate liquid pump, exchanging heat with the high-temperature heat exchanger and the parallel high-temperature heat return system, before entering the plate high-temperature regenerator. There, it is heated by external steam to generate refrigerant vapor, concentrating it into a high-concentration absorbent. Finally, it returns to the absorber to absorb refrigerant vapor generated from evaporation in the evaporator, diluting it into a dilute solution. This invention effectively reduces the overall solution filling volume and unit cost, significantly improves the unit's heat exchange efficiency, effectively stabilizes the liquid level, ensures stable unit operation, and enhances the unit's operational safety.
