Abstract
In a compact absorption type refrigerator which eliminates an ill effect caused by the local overheating of a heating chamber in a high-temperature regenerator with a liquid pipe boiler, a high-temperature regenerator 5 heats a heating chamber 63 in which vertical liquid pipes 51 for circulating a diluted absorption solution 2a are arranged in a matrix form with the combustion surface 60D2 of a plane flame type burner 60X to evaporate refrigerant vapor 7a from the diluted solution 2a. The width 60BX of the combustion surface 60D2 within a horizontal plane is made smaller than the width 51BX of the liquid pipes 51 arranged in a matrix form, the volume of flames on the combustion surface 60D2 within the horizontal plane is made large at a central portion and small at portions on wall 50B sides, or the volume of flames on the combustion surface 60D2 within a vertical plane is made large at an upper portion and small at a lower portion so that the diluted solution 2a flows in an upward direction in flow passages 51a and a downward direction in flow passages 50a and 50b.
