Title:
ICE HEAT STORAGE DEVICE
Document Type and Number:
Japanese Patent JP3042179
Kind Code:
B2
Abstract:
PURPOSE: To provide an ice heat storage device capable of effectually utilizing latent heat of ice by effectually melting ice in a heat storage reservoir and taking out cold water.
CONSTITUTION: Water in a heat storage tank 22 is made into ice by a brine which returns from an outlet 26 of a heat exchanger coil 24 provided to be buried in water with which the heat storage tank 22 is filled through a brine pump 28 and cooling means 30 to an inlet 40 of the heat exchanger coil 24. Then, ice 84 made in the heat storage tank 22 is melted as a cold heat source of an air conditioner with the aid of the melted ice water returning from a melted ice water intake port 50 provided in the vicinity of a water bottom inn the heat storage tank 22 through a melted ice water pump 54, and the air conditioner 56 and from a plurality of water sprinkling pipes 68, 70, 72 including valve mechanisms 74, 76, 78 provided on the upper of the heat storage tank 22. Thereupon, the valve mechanisms 74, 76, 78 are opened and closed on the basis of a detection result by one or more detection sensors for detecting the existence and position of the ice in the heat storage tank 22.
