| Abstract: | The timeshare electricity price policy in Fujian Province was introduced in this paper.Different operating modes that used thermal energy storage and increased running time in nighttime were simulated based on a selected warehousing facility.The results show that the operating electricity bill for refrigerated warehouses can be reduced by 47.3% even more under ideal condition.The operating electricity bill for the observed warehouse can be reduced by 31%.The nighttime wet bulb temperatures were 1.2-1.8℃ lower than that of daytime in Xiamen city based on hourly temperatures from Xiamen Meteorological Agency.It was indicated from calculation that the COPs of refrigeration plants at nighttime will be improved by 1.6% to 2.92%. |
