Changli Leber Supermarket Electric Heat Storage Cold Storage Feasibility Analysis

Along with the high-speed development of global economy,the energy shortage andenvironment deterioration is increasingly serious.Energy and environment problemincreasingly prominent make people realize the importance of sustainability. Withincreasing of urban population,the building energy consumption in total energyconsumption of the proportion of more and more big,especially the supermarket buildingthis type of energy consumption increasing, how to alleviate the supermarket buildingenergy consumption is increased,more and more become the focus of building energyefficiency.This paper mainly studies the installation or alteration in the supermarket buildingfeasibility of cold/heat storage system, and is verified by an example analysis. Through avariety of cool storage and heat storage way of system analysis, ice storage, with its highefficiency, low power consumption, stable ice storage rate, melting the advantages of highefficiency, energy saving features prominent, compared to other storage system seems tobe more able to realize the energy saving of building requirements. At the same time inregenerative system adopts the electrical boiler night regenerative heat storage water tank,heat storage water tank heating system during the day.According to the characteristics of supermarket building energy consumptionanalysis of related research, such as the supermarket building can occupy the publicbuilding energy consumption in China is relatively larger in proportion. Supermarketbuilding energy consumption mainly include lighting, HVAC, rental shops andsupermarket refrigerated, accounted for88%of energy. In the four part, the HVAC systemsupermarket exist throughout the day to meet the load demand of all weather conditions,there exists the problem of low efficiency. In the air conditioning energy consumption willremain high, which seriously hampered the supermarket building their own economiccharacteristics. Through the construction of cold storage, heat storage are combined, andthe building in the summer, supermarket building at night cold storage, cold storage in thedaytime and direct supply unit to the supermarket building combined cooling; in thewinter, supermarket building at night using the boiler heat storage to storage tank, mainly to release the heat accumulation with in the daytime peak stage supermarket, auxiliaryheating, achieve heat load supermarket building requirements. Both summer and winter,electricity at night at a low ebb, increase the night power usage, to ease the pressure onelectricity tariff preferential policy; and the evening also provide policymakers with theeconomic high. But through the analysis, the supermarket building can save the cost of32.4%in the summer, in saving the cost of37.5%winter, in a normal year savingoperating costs401259yuan.
