<p><P>PROBLEM TO BE SOLVED: To provide an ice storage unit that prevents the case where the same cannot handle an air conditioning load because ice is lost before a peak cut time ends by adjusting the amount of brine flowing through an ice storage layer using a water level of the ice storage layer. <P>SOLUTION: An ice storage unit includes: heat source units 1a and 1b for cooling first brine; a heat exchanger 3 that is connected with the heat source unit by first piping and exchanges heat between the first brine and second brine; a brine pump 4 that moves the first brine; a heat exchanger 2a for ice making that is connected in parallel with the first piping and makes ice by the first brine cooled by the heat source units; an ice storage tank 2 having the heat exchanger for ice making; a flow rate control unit that controls the amount of the first brine flowing into the heat exchanger for ice making; a water level sensor 2b that measures the water level of the ice storage tank; and a controller 30 into which a measurement value of the water level sensor is input. The controller adjusts the amount of the first brine flowing into the heat exchanger for ice making by controlling the flow rate control unit based on the measurement value of the water level sensor. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
