Technology And Economic Analysis For The System Of Cold Air Distribution With Ice Storage

In the background of the global energy crisis,energy conservation,low carbon and environmental protection have become to be an important topic of sustainable development. According to the energy conservation theory,storing energy technology can not save energy,but they make major effect on modern industrial with multi-system.The ice storage technology is used in the high consumption air-conditioning systems which can balance the pressure of electricity grid and reduce electricity peak load,and help power leveling and efficient production.At present,there are lots of studies about the ice storage air conditioning system and the large temperature difference air conditioning supply system,such as engineering realization and economic evaluation.But the study on economy and applicability of the cold air distribution system with ice storage research is rare. The research work about this focus on comparing individual case domestic,while that is scarce in foreign academe.The economic profits are analyzed in this thesis when the ice storage and cold air distribution technology used in air-conditioning system.The effect of air inlet parameters with low temperatures and low relative humidity on air supply volume and energy consumption was analyzed.In addition,useing round airduct to reduce airduct supplies and fan energy consumption greatly was verified by hydraulic calculation.When indoor design parameters was changed,the effect of the entire heat load and latent heat load on air supply volume was analyzed by psychrometric chart.With all regions’hourly enthalpy of Chinese special architecture environment meteorological parameters data set,domestic31typical cities’proportion of energy saving-cycling model of the whole cooling period was analyzed for the first time,Therefore the suitability of cold air distribution system with ice storage in five climate districts was summed up. The mathematics models is established by which the ice storage routine air conditioning system,routine air conditioning system are established.Then they are compared with a cold air distribution system with ice storage engineering case in hot summer and warm winter zone.Contrastive contents include:the increases of cold source between ice storage and routine design,the decreases of duct and terminal equipment between cold air distribution system and routine design,under electricity favourable policy,year operational cost of the three case. At last, simple analysis、dynamic analysis and life cycle cost analysis method are used to research the Economy of parameter above.
