ABSORPTION REFRIGERATING MACHINE/WATER COOLING AND WARMING MACHINE

PROBLEM TO BE SOLVED: To improve the performance of an absorption refrigerating machine/ water cooling and warming machine, to simplify the structure of the machine and so on, by improving the structure, arrangement, etc., of the equipment constituting the low-temperature drum of the machine. SOLUTION: A gas extraction box 126 is formed by surrounding part of a pipe group in an absorber 108 and a noncondensable gas is collected in the box 126 and extracted. Refrigerant vapor passages 132 are provided on both sides of the pipe group section in the absorber 108 and, at the same time, the lower parts of the passages 132 are closed with baffles 134. The pipe arranging intervals in the upper part of the pipe group are made longer so as to omit an eliminator by making the evaporator 110 horizontally longer in shape. The evaporator 110 and absorber 108 are arranged in the vertical direction, and a condenser 112 and a low-temperature regenerator 114 are arranged in the lateral direction so that the regenerator 114 may come to a high-temperature regenerator side. The liquid outlet box 116 of the regenerator 114 is arranged on the condenser 112 side. The refrigerant flushing pipe 142 of the evaporator 110 is constituted of a flushing pipe and a lower pan.
