摘要： PROBLEM TO BE SOLVED: To provide a method for controlling an ice storage tank capable of extracting water or brine at a temperature not higher than a specified temperature for a required time even if the working temperature is low.
SOLUTION: The method for controlling the ice storage tank cools a heat medium by ice produced by freezing water in the ice storage tank and making ice grow. The method comprises the steps of receiving in the tank the heating medium for cooling cooled by a refrigeration machine and freezing water by the heating medium to make the ice grow; receiving a heated secondary side heating medium (water or brine) from an inlet of the tank; cooling the secondary heat medium by melting the ice which has grown and supplying the secondary side heat medium to the outside through an outlet of the tank and; interrupting cooling of the secondary side heat medium to make ice remain in the tank at an specified ice packing factor when the condition is satisfied that the ice packing factor(IPF) in the tank reaches a specified value during cooling of the secondary side heat medium.

摘要： PURPOSE:To utilize low temperature waste heat of a phosphoric acid type fuel cell, etc., and alleviate use of low-cost midnight power and mismatch between waste heat and heat utilizing time by introducing chilled water cooled by an evaporator of a heat pump or an evaporator to a refrigerant heat exchanger of a heat storage system, and heat exchanging it with refrigerant. CONSTITUTION:A solution 9 is circulated between a cold storage heat exchanger 1 and a solution tank 3, chilled water 21 is circulated between a refrigerant heat exchanger 2 and a heat pump evaporator 22, and heat medium 13 is circulated between the exchanger 1 and a heat source 6a. When a heat pump compressor 23 is driven, high temperature-high pressure refrigerant gas flows into a condenser 24 to be condensed. Then, liquid refrigerant is passed through an expansion valve 25 and adiabatically expanded, introduced into the evaporator 22 to cool chilled water 21 to be evaporated to be vaporized by itself. The discharged refrigerant gas is sucked to the compressor 23 and again compressed. Thus, coolant temperature at the time of cold storage operation can be set to about 30 deg.C by an operation of the pump utilizing midnight power.

The supercooled water 2 flows through a header 7 and is sent through distribution parts 10 and branching pipes 8 to each of the thermal storage tanks 3. The header 7 is extended to an area above the thermal storage tanks 3 provided farthest from the supercooling device 1, and the rear end of the header 7 is provided with an elbow 9 connected to the branching pipe 8 so as to transfer the supercooled water 2 to the thermal storage tanks 3. The supercooled water 2 is made to fall onto collision plates 4 provided as a device for relieving the supercooled water from the state of being supercooled. Thus, collision is given to the supercooled water so that part of the supercooled water changes into ice to form sherbet-like ice 11 in the thermal storage tanks 3.
