<p>A refrigerant displacement device (32) physically takes up volume of a subcooler (B C 34) that would normally be occupied by refrigerant. The refrigerant displacement device (32) can be a baffle (A) structure with orifices (2) through which heat exchange tubes (16 , 36) of the subcooler (B ,C , 34) are allowed to be inserted. Refrigerant is still allowed , however, to flow through the remaining volume of the subcooler (B , C , 34) and through openings constructed , e.g. annuluses , between the tube(s) (16 , 36) and the refrigerant displacement device (32), so as to allow refrigerant flow from an inlet of the subcooler (B, C ,34) to an outlet (5 , 15) of the subcooler (B , C , 34). The refrigerant displacement device (32) is used to reduce subcooler refrigerant charge while enhance heat transfer performance , e.g. by maintaining and/or increasing subcooler performance.</p> |
