Absorption refrigerating machine

Abstract

Abstract PURPOSE: To obtain an absorption refrigerating machine, easily retaining the smooth circulation of refrigerant and absorbing liquid, by a method wherein the discharging pressures of respective pumps are controlled by a controller in accordance with a pressure difference between the group of a generator as well as a condenser and the group of an evaporator as well as an absorber. CONSTITUTION: Upon cooling operation, a controller CO increases or decreases the discharging pressure of a pump PL for diluted absorbing liquid in accordance with a difference [Pc -PE] between the pressure Pc of the group of a generator as well as a condenser and the pressure Pg of the group of an evaporator as well as an absorber whereby the outlet amount and inlet amount of absorbing liquid in the absorber A and the generator G can be balanced thereby permitting the retention of smooth circulation of the absorbing liquid. Upon heating operation, the discharging pressures of a pump PR for refrigerant solution and the pump PH for concentrated solution are increased and decreased by the controller CO in accordance with the increase and decrease of a pressure difference [PE-Pc ] between the group of the evaporator as well as the absorber and the group of the generator as well as the condenser whereby the outlet and inlet amount of the generator G and the absorber A as well as the outlet and inlet amount of refrigerant in the evaporator E can be balanced thereby permitting the retention of smooth circulation of the refrigerant and the absorbing liquid.
