Absorption type heat exchange system

Abstract

According to the absorption type heat exchange system, the outlet temperature of a heated fluid is higher than the inlet temperature of a heating source fluid. The absorption type heat exchange systemcomprises the following parts: a first absorption part and a second absorption part used for raising the temperature of a first heated fluid; a first condensation part and a second condensation partused for raising the temperature of a second heated fluid; a first evaporation part and a second evaporation part used for lowering the temperature of the heating source fluid; and a first regeneration part and a second regeneration part used for lowering the temperature of the heating source fluid. Through absorption type heat pump circulation of an absorption liquid and a refrigerant, the pressure and the temperature in the first evaporation part are higher than those in the first condensation part, the pressure and temperature of the second evaporation part are higher than those of the second condensation part, and a part of the heating source fluid branched from the heating source fluid before being introduced into the first evaporation part, the second evaporation part, the first regeneration part and the second regeneration part is introduced into the first absorption part and the second absorption part as the first heated fluid.

Description

technical field [0001] The present invention relates to an absorption heat exchange system, and more particularly to an absorption heat exchange system for exchanging heat between two fluids in such a manner that the outlet temperature of the rising fluid is higher than the inlet temperature of the lowering fluid. Background technique [0002] A heat exchanger is widely used as a device for exchanging heat between a high-temperature fluid and a low-temperature fluid. In a heat exchanger that directly exchanges heat between two fluids, the outlet temperature of the low-temperature fluid cannot be made higher than the inlet temperature of the high-temperature fluid (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent No. 5498809 (refer to Figure 11 Wait) [0004] As one use of the heat exchanger, recovery of exhaust heat is cited. Exhaust heat is unused and discarded heat, so if the outlet temperature of the fluid whose temperature is raise...

Problems solved by technology

Exhaust heat is unused and discarded heat, so if the outlet temperature of the fluid whose temperature is raised by recovering the exhaust heat can be made higher than the inlet temperature of the fluid whose temperature is lowered by depriving heat including the exhaust heat, then widen the scope of use
