Title:
HEAT SOURCE SYSTEM OPERATION MANAGEMENT DEVICE, HEAT SOURCE SYSTEM OPERATION MANAGEMENT METHOD, AND COMPUTER PROGRAM
Document Type and Number:
WIPO Patent Application WO/2016/125583
Kind Code:
A1
Abstract:
An operation management device 1 comprises: a refrigerant return temperature predicting unit to predict the refrigerant return temperature Tr of a refrigerant returning to a heat source system 2 from air conditioning equipment 3; a heat storage capacity estimating unit to estimate the heat storage capacity of the heat source system on the basis of the predicted refrigerant return temperature Tr; and an operation planning unit to create a plan for heat source system operation on the basis of the estimated heat storage capacity. The heat source system may also comprise: a thermal storage tank 20 to supply stored refrigerant to the air conditioning equipment; a refrigerant generating unit 22 to cool refrigerant returning from the air conditioning equipment via the thermal storage tank and to supply the cooled refrigerant to the thermal storage tank; a refrigerant feed temperature detecting unit 24 to measure the temperature of the refrigerant sent from the refrigerant generating unit to the thermal storage tank; and a refrigerant return temperature detecting unit 25 to measure the temperature of the refrigerant returning from the thermal storage tank to the refrigerant generating unit.
