効開を出せなかった。DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the above-described configuration, even if the cold storage tank 1 stores ice cold to increase the amount of cold storage heat, the cold storage tank 1
The tap water that had flowed in from the water supply pipe 7 did not sufficiently dissolve the ice 10, and flowed out from the water discharge pipe 8 without the water temperature becoming too low. This is because the number of particles of water that come into contact with and separate from the ice 10 is small and the number of particles that are not in contact is predominantly large, and the water flows in the cold storage tank 1, that is, the heat exchange between ice and water. This occurs due to inefficiency, and especially when a large amount of cold water is continuously discharged, the sensible heat of the cold water in the cold storage tank 1 does not change much, and the cold water discharge amount does not change so much. I couldn't get the effect.
