ELECTRIC POWER/HEAT AMOUNT WORKING SYSTEM FOR LARGE-SCALED STORE

摘要

PROBLEM TO BE SOLVED: To provide an electric power/heat amount working system for large- scaled store which assures standardization of an electric power load and has greater energy saving by enabling the use of only a commercial power supply in the night and the use of only electric power of an independent electric power plant without use of the commercial power supply in the daytime. SOLUTION: A freezing heat amount load 17 is cooled with cold brine cooled with a freezer 9 for the freezing heat amount load in the daytime and in the night, and a refrigeration heat amount load 18 is cooled using in the night ice water stored in an ice storage tank 12 with a freezer 10 for a refrigeration heat amount load in the night and is cooled with brine cold water from an absorptive freezer 13. For operation of each heat amount load only electric power of a commercial power supply 1 is employed in the night while only electric power of an independent electric power plant 4 is employed in the daytime.
