In a heat storage management system for switching a heat storage mode and a heat storage utilization mode of a heat medium circuit, heat storage can be utilized without waste, frequent switching is avoided, and switching loss of the heat medium circuit and adverse effects on the service life of a switching valve are suppressed. A heat storage management system according to the present invention is provided with: a heat storage unit for storing heat or cold generated by a heat source; a heat medium circuit in which a heat medium circulating in the heat medium circuit exchanges heat with the heat storage unit; and a control unit that switches the heat medium circuit between a heat storage mode in which heat is stored in the heat storage unit and a heat storage utilization mode in which the heat stored in the heat storage unit is utilized. One or both of a first switching threshold value for switching from the heat storage mode to the heat storage utilization mode and a second switching threshold value for switching from the heat storage utilization mode to the heat storage mode is/are changed.
在对热媒回路进行蓄热模式和蓄热利用模式切换的蓄热管理系统中,能没有浪费地利用蓄热,避免频繁地进行切换,从而抑制热媒回路的切换损耗和对切换阀的寿命的不良影响。本发明的蓄热管理系统包括:蓄热部,该蓄热部对热源所产生的热量或冷量进行蓄热;热媒回路,该热媒回路中循环的热媒与蓄热部进行热交换;以及控制部,该控制部对热媒回路进行在蓄热部中储存热量的蓄热模式和利用蓄热部中储存的热量的蓄热利用模式的流路切换,控制部基于蓄热部的状态,变更从蓄热模式切换到蓄热利用模式的第一切换阈值和从蓄热利用模式切换到蓄热模式的第二切换阈值中的一方或双方。
