<p><P>PROBLEM TO BE SOLVED: To surely cool steam drain from a high temperature regenerator to a stable temperature free from flashing, and to improve efficiency of a refrigerating machine in partial load. <P>SOLUTION: This steam absorption type refrigerating machine includes the high temperature regenerator 5 applying steam as a heating source, a low temperature regenerator 4, a condenser 3, an evaporator 1, an absorber 2, a low temperature solution heat exchanger 9, a high temperature solution heat exchanger 10 and drain coolers 11, 12 for cooling the steam drain. A bypass pipe 50 is disposed in a state of branching from a dilute solution pipe and bypassing the low temperature solution heat exchanger 9, and the drain cooler 11 exchanges heat between the dilute solution from the bypass pipe and the steam drain from the drain pipe. Further it includes a flow rate adjustment valve 37 disposed at an upstream side with respect to the drain cooler in the bypass pipe, a temperature detector 35 disposed in the drain pipe, and a control device controlling a temperature of the discharged drain by adjusting the flow rate adjustment valve according to the temperature detected by the temperature detector. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
