ABSTRACT:
An absorption refrigerating/heating apparatus which performs in any of three modes; refrigerating, thermodynamic heating, and direct flame heating and improves the thermal efficiency during the operation of a direct flame heating mode to decrease the running cost. In the direct flame heating mode, the refrigerant and/or the absorbent is passed to the regenerator to decrease the concentration of the absorbent in the solution in the regenerator. Consequently, the temperature of the solution required for maintaining the vapor pressure in the regenerator at a desired rate can be lowered thus saving the heat needed for heating the solution.
