A condenser for a refrigerator and a method of operating the condenser, in which heat exchanger tubes for cooling the condenser each have brush receivers and cooling water inlet/outlet ports at both ends thereof, one of the brush receivers accommodating a brush for washing the tube, and cooling wate
A condenser for a refrigerator and a method of operating the condenser, in which heat exchanger tubes for cooling the condenser each have brush receivers and cooling water inlet/outlet ports at both ends thereof, one of the brush receivers accommodating a brush for washing the tube, and cooling water supply and discharge pipes are connected to the cooling water inlet/outlet ports, respectively, through a four-way valve. When the condenser is to be cooled, the opening of the four-way valve is controlled on the basis of the pressure in the condenser or the temperature of the cooling water being discharged to thereby control the flow rate of cooling water supplied to the heat exchanger tubes, whereas when the heat exchanger tubes are to be washed, the four-way valve is switched so as to change the direction of flow in the heat exchanger tubes, thereby allowing the brush to travel through the tubes automatically, and thus automatically washing the inside of the tubes.

A condenser for a refrigerator, having heat exchanger tubes for cooling said condenser each of which has brush receivers and cooling water inlet/outlet ports at both ends thereof, one of said brush receivers accommodating a brush for washing said tube, cooling water supply and discharge pipes which are connected to said cooling water inlet/outlet ports, respectively, through a four-way valve, and a motor for driving said four-way valve through a plurality of positions, wherein the position of said four-way valve is switchable to control the valve opening of said four-way valve for controlling the flow rate of cooling water supplied to said heat exchanger tubes, and to change the direction of flow in said heat exchanger tubes. A method of operating a condenser for a refrigerator, having heat exchanger tubes for cooling said condenser each of which has brush receivers and cooling water inlet/outlet ports at both ends thereof, one of said brush receivers accommodating a brush for washing said tube, and cooling water supply and discharge pipes which are connected to said cooling water inlet/outlet ports, respectively, through a four-way valve, wherein, when said condenser is to be cooled, the valve opening of said four-way valve is controlled on the basis of the pressure in said condenser to thereby control the flow rate of cooling water supplied to said heat exchanger tubes, whereas, when said heat exchanger tubes are to be washed, said four-way valve is switched so as to change the direction of flow in said heat exchanger tubes, thereby allowing said washing brushes to travel through said tubes automatically, and thus automatically washing the inside of said tubes.
