SUPERCOOLED WATER DYNAMIC TYPE ICE HEAT STORAGE TANK DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a means for stably preventing freezing in a return pipe and efficiently utilizing the cold in an ice heat storage tank device producing ice from the supercooled water in piping of a sealed system.;SOLUTION: A bypass circuit is formed on the way of the return pipe, a first heat exchanger and a second heat exchanger are arranged in series in the bypass circuit, a secondary side of the first heat exchanger is connected with an air conditioning system line for processing night cooling load, and a secondary side of the second heat exchanger is connected with a cooling water recooling circuit communicated with a refrigerating machine of an air conditioning system. A secondary side of the first heat exchanger is connected with a cooling device for building frame heat storage of a building. The first and second heat exchangers are formed as an internal circuit of an integrated heat exchanger.;COPYRIGHT: (C)2006,JPO&NCIPI
