<P>PROBLEM TO BE SOLVED: To enhance condensation efficiency of a water-cooled condenser and to perform efficient ice making operation. <P>SOLUTION: A third water feed valve 35 which is opened and closed under the control of control means C is arranged in a third water feed pipe 34 connected to an external water source. Cooling water amount detection means 50 of sending a water amount detection signal to the control means C is arranged at a cooling water tank 45. After ice making operation by an ice making part 21, remaining ice making water W2A remaining in an ice making water tank 26 is collected in the cooling water tank 45, and third water feed valve 35 is controlled to be opened to feed external water from the external water supply to the cooling water tank 45 until the cooling water amount detection means 50 sends out a water amount detection signal. The control means C controls the third water feed valve 35 on the basis of the water amount detection signal from the cooling water amount detection means 50 to control the feed amount of the external water (W1). <P>COPYRIGHT: (C)2013,JPO&INPIT |
