Abstract

The invention provides an absorption refrigerating machine to prevent any condensation of steam contained in exhaust gas even in a starting operation or a partially loaded operation having a mechanism to collect the heat from the exhaust gas. An absorption refrigerating machine has first and second exhaust gas heat collectors 23 and 24, an absorbent pipe (a bypassing absorbent pipe) 11B to allow dilute absorbent from a low-temperature heat exchanger 9 to flow in a bypassing manner around the exhaust gas heat collector 24, a flow rate control valve 25 provided on an absorbent pipe 11A leading to the second exhaust gas heat collector 24, and a controller 27 to control the opening of the flow rate control valve 25 so that a temperature sensor 26 continuously detects the predetermined temperature (for example, 100 DEG C.) higher than the dew point of the exhaust gas.

Description

technical field

[0001] This invention relates to absorption refrigerators. Background technique

[0002] Such as Figure 5 As shown, it is well known that the existing absorption refrigerating machine is to try to make the waste gas discharged from the gas burner 2 which heats and boils the dilute absorption liquid of the high temperature regenerator 1 sequentially sent to the first waste gas heat recovery device 23, which is arranged in the absorption liquid pipe Between the high-temperature heat exchanger 10 of 11 and the high-temperature regenerator 1; the second waste gas heat recovery device 24, which is arranged between the low-temperature heat exchanger 9 and the high-temperature heat exchanger 10, makes the transfer from the absorber 7 to the high-temperature regenerator As the temperature of the dilute absorbing liquid in 1 rises, the amount of heating necessary for the gas burner 2 decreases, reducing fuel consumption.

[0003] That is to say, in the absorption re...
