Abstract:
1. A condenser for a refrigerating machine comprising: a vessel into which a gaseous refrigerant is introduced; and a group of heat exchanger tubes disposed in said vessel for condensing and liquefying a gaseous refrigerant by heat exchange between said gaseous refrigerant and cooling water circulating in said heat exchanger tubes; wherein said heat exchanger tubes are disposed at an equal interval, and a group of heat exchanger tubes located in a lower region are used for supplying said cooling water forward and another group of said heat exchanger tubes located in an upper region is used for returning said cooling water backward, and the number of heat exchanger tubes located in said upper region is made smaller than the number of heat exchanger tubes located in said lower region by making the area of said upper region smaller than the area of said lower region.
