ABSORPTION REFRIGERATOR FOR IMPROVING EFFICIENCY OF LOW-TEMPERATURE HEAT EXCHANGER AND PREVENTING CONCENTRATED ABSORPTION LIQUID FROM CRYSTALLIZING EVEN IF TEMPERATURE OF DILUTE ABSORPTION LIQUID DROPS SUDDENLY

摘要

PURPOSE: An absorption refrigerator is provided to effectively recover heat of the exhaust gas and to restrict the temperature of concentrated absorption liquid supplied from a low-temperature regenerator to an absorber from lowering abnormally and crystallizing by a low-temperature heat exchanger. CONSTITUTION: An absorption refrigerator(100) is composed of a high-temperature regenerator(1), a low-temperature regenerator(2), a condenser(3), an evaporator(4), an absorber(5), a low-temperature heat exchanger(6) for exchanging heat between absorption liquid flowing into or out of the absorber, a high-temperature heat exchanger(7) for exchanging heat between absorption liquid flowing into or out of the high-temperature regenerator, and heat recovery devices(8,9) for recovering the residual heat of arrangement fluid discharged from the absorber and inserted into the low-temperature heat exchanger by heating the absorption liquid and heat-exchanging the arrangement fluid discharged from the high-temperature regenerator with the absorption liquid discharged from the absorber.
