<p>PROBLEM TO BE SOLVED: To force-feed absorbent solution from the low pressure side to the high pressure side even in case that the pressure working on the low pressure side is low, by pushing oil into a diaphragm pump and drawing oil out of the same diaphragm pump thereby reciprocating a diaphragm. SOLUTION: A piston 25 is arranged in the cylinder section 21 of the pump body 20, and it pushes oil into a diaphragm pump 11 through a main oil line 23 and drawing it out of the diaphragm pump 11, and also pushes oil in an oil reservoir 22 through an oil line 40 for replenishment or draws it out of the oil reservoir 22 so as to reciprocates the diaphragm 31 within the diaphragm pump 11. The reciprocation of this diaphragm 31 draws an absorbent solution out of the low pressure side of a heat exchange system, and next pushes the absorbent solution to the high pressure side of the heat exchange system.</p> |
