EXHAUST HEAT RECOVERY-TYPE ABSORPTION REFRIGERATOR

摘要

PPROBLEM TO BE SOLVED: To provide an exhaust heat recovery-type absorption refrigerator which prevents the leakage of waste gas with a simple structure while efficiently performing the heat exchanging upon heating the refrigerant solution by directly performing the heat exchanging between the waste gas discharged from a combustion system and the refrigerant solution. PSOLUTION: This exhaust heat recovery-type absorption refrigerator comprising a high-temperature regenerator for heating the refrigerant solution stored in a storing part to separate the same into the refrigerant solution and the refrigerant vapor, a low-temperature regenerator for heating the refrigerant solution sent from the high-temperature regenerator by the refrigerant vapor sent from the high-temperature regenerator, a condenser for cooling and condensing the refrigerant vapor having passed through the low-temperature regenerator, an evaporator for evaporating the refrigerant liquid obtained by the condenser, and an absorber for absorbing the refrigerant vapor generated by the evaporator to the refrigerant solution sent from the low-temperature regenerator, further comprises a waste gas heat exchanger for heating the refrigerant solution flowing out from the low-temperature regenerator by the waste gas having passed through the high-temperature regenerator.
