CONDENSER FOR REFRIGERATING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a shell and tube type condenser for refrigerating machine arranged to feed a cooling fluid through a plurality of heat exchanger tubes arranged horizontally and to feed refrigerant downward on the outside of the heat exchanger tubes in which transfer of condensation heat is not impeded by a condensation liquid film being produced in the heat exchanger tubes. SOLUTION: Cooling water flowing into a condenser from a cooling water inlet 8 flows into heat exchanger tubes 2 at the lower part, turns back at the left end and flows through the heat exchanger tubes 2 at the upper part before flowing out from a cooling water outlet 9. Refrigerant gas 15 flows from a refrigerant gas inflow nozzle 16 into the condenser where it is cooled by cooling water flowing through the heat exchanger tubes 2 and condensed. Upper part of the heat exchanger tubes 2 facing the refrigerant gas inflow nozzle 16 side is covered with a punching metal 11.
