| 摘要 |
The object of the invention is to improve heat efficiency of an absorption refrigerator driven by exhaust heat supplied from the other apparatus as a part of heat sources.A diluted absorption liquid that absorbs a refrigerant in an absorber to decrease in concentration of the absorption liquid is discharged to the absorption liquid pipe and then branched to be supplied to first and second spaces of an exhaust heat regenerator. The diluted absorption liquid is heated by exhaust gas supplied through the exhaust heat supply pipe in each space and concentrated and regenerated for the first time. The absorption liquid concentrated and regenerated in the first space is supplied to a high-temperature regenerator and further heated by a gas burner. The heated absorption liquid is flown into a vapor-liquid separator in a mixed state of vapor and liquid, and then separated into refrigerant vapor and further concentrated absorption liquid.
