Title:
ABSORPTION REFRIGERATION UNIT
Document Type and Number:
Japanese Patent JP3889655
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To increase the heat recovery of the heat of exhaust gas emitted from a combustor added to a high-temperature regenerator.
SOLUTION: First, second and third exhaust gas heat recovering instruments 23, 24 and 25 are provided, in which the exhaust gas radiates the heat through the heat exchange with dilute absorption liquid, and distribution control valves 26 and 27 are provided. The distribution control valve 27 is controlled so that a temperature sensor 29 continuously detects a predetermined temperature (adequate temperature higher than the dew point of steam contained in the exhaust gas, for example, 100°C), and a controller 30 to control the distribution control valve 26 so that the temperature detected by a temperature sensor 28 maintains a predetermined value (a temperature slightly higher than the crystallization temperature of concentrated absorption liquid, for example, 40°C) is provided. In addition, the third exhaust gas heat recovering instrument 25 and an exhaust pipe 22 on the downstream side thereof are formed of weather resistant steel or rust-proof steel.
