VACUUM BOILING-BASED SOLUTION REGENERATION APPARATUS FOR IMPLEMENTING CONTROLLABLE CONDENSATION

摘要

A vacuum boiling-based solution regeneration apparatus for implementing controllable condensation comprises a refrigerant loop, a solution loop, a vacuum maintaining loop, and an air loop. The apparatus regenerates a solution by means of a characteristic that a solution boiling point is lowered in a vacuum state, separately uses a condensation heat quantity and an evaporation cold quantity in the refrigerant loop as a regenerative heat source and a condensation cold quantity of the solution, and can flexibly regulate the solution regeneration rate and the solution regeneration concentration. In addition, by adjusting a working pressure in a finned tube heat exchanger in the air loop, the evaporation temperature of a refrigeration system can be regulated. Therefore, the apparatus has a higher solution regeneration efficiency and system energy efficiency.
