Achieved COP 0.73, even with double lift refrigeration cycle

*Detailed product explanation

■Refrigerants evaporate from an evaporator and cool cold water flowing inside of evaporator tubes. Refrigerants evaporated at this time go to an absorber and get absorbed into a thick absorption liquid (a concentrated solution) flowing down from a generator.

■Thick solution (a concentrated solution) from a generator and weak solution (a dilute solution) from an absorber exchange heat at an absorption heat exchanger located at the upper part of the absorber to improve absorption power of the concentrated solution and enhance the efficiency of the chiller.

■The concentrated solution coming through the absorption heat exchanger absorbs refrigerant vapor and becomes a weak solution (a dilute solution). Absorption heat generated at this time is conveyed to cooling water.

■Absorption liquid (a dilute solution) diluted at an absorber goes to a generator through an absorption heat exchanger and a heat exchanger. Hot water of 95℃ heats this dilute solution and generates refrigerant steam.

■Solution (a dilute solution) diluted at an absorber goes to a generator through an absorption heat exchanger and a heat exchanger. Hot water of 95℃ heats this dilute solution and generates refrigerant vapor.

■Refrigerant steam generated from the generator gets condensed outside of condenser tubes and flows down to the evaporator. Cooling water absorbs heat generated when refrigerant gas gets condensed at condenser tubes.
