Heating heat source or electric production system utilizing waste heat at medium and low temperatures, and control method thereof

摘要

A system for producing a heat source for heating or electricity, using medium/low-temperature waste heat includes: an absorption-type heat pump (100) supplied with a driving heat source and heat source water to heat a low-temperature heat medium; a regenerator heat exchange unit (210) for supplying a regenerator (110) with a driving heat source using waste heat; an evaporator heat exchange unit (220) for supplying an evaporator with heat source water; a heat medium circulation line (310) for circulating a heat medium; a generation unit (400) branching off from the heat medium circulation line (310) and producing electricity; a heat production unit (500) branching off from the heat medium circulation line (310) and supplying a heat-demanding place with a heat source for heating; and a switching valve unit (600) for controlling the flow of heat medium supplied the generation unit (400) or the heat production unit (500).
