Abstract


In recent years, with the rapid development of the industry, the city power consumption increased dramatically in some cities the power shortage situation, the extensive use of air conditioning exacerbate the power load, many cities had to take a \electricity tensions. The emergence of the ice storage air-conditioning electricity peak load shifting \Traditional ice storage air conditioning is the use of the preferential policies of the electricity price policy, reduce certain operating costs, grid peak load shifting economic benefits. But in a fundamental sense, this thermal storage did not realize the energy conservation and environmental improvement. Northern China has a unique climate characteristics and rich natural cold resources, if we can save these natural cold resources to the summer, this part of the cooling capacity can be used as a summer air conditioning cold source to adjust the room temperature. Natural cold resources air conditioning Northern Development, both energy conservation and environmental protection, which is a real sense of green air conditioning and ice storage air-conditioning, electric air conditioner with and use. Firstly, from the latent heat of ice, the performance of the sensible heat of its storage capacity for theoretical analysis, the cooling load and air volume air conditioning system and natural cold resources analysis and calculation, as well as heat exchange system of the natural the Cold resource auxiliary air conditioning the heat transfer process. Through the above analysis, combined with the test program the for the cold natural resources auxiliary air conditioning system design and build a test device, ice storage test, performance test three trials of air conditioning test and air-conditioning heat exchangers. The data acquisition system using LabVIEW graphical programming software is widely used, and the completion of the acquisition of the temperature of the air conditioning system of natural the Cold resource auxiliary control program design, the whole acquisition process is fully automated, saving manpower, resources, and improve the efficiency. Through this study, the following conclusions: 1. Store winter ice to summer is practicable, the ice temperature variation during storage by ice storage tests to find reduce ice cooling loss during storage of specific measures. 2. Through the blower test to verify the feasibility of the natural the Cold resource auxiliary air conditioning system. 3. Assisted by the resources of the natural cold air conditioning heat exchangers of the heat exchange system test to find the better combination of programs in the system between the influencing factors, and finally calculate the convective heat transfer coefficient and the overall heat transfer coefficient, and to provide a basis for further research work. 4. Through economic analysis, if the increase in the reservoir ice volume, improve thermal storage efficiency, natural cold resources auxiliary air conditioning has a good economy, and the ice becomes water during use, recycling, energy conservation, environmental protection. The technological innovation of this study is that the storage characteristics of natural ice of the northern region for the first time a theoretical analysis and experimental research, based on natural cold resources auxiliary air conditioning system design and heat transfer performance of the heat exchange system optimization test get the better combinations of natural cold resources auxiliary air conditioning heat exchanger system parameters, calculate the convective heat transfer coefficient and the overall heat transfer coefficient of the heat exchange system for future similar trials to provide a theoretical basis and test reference. The study also to fill in a gap on the study of the natural the Cold resource auxiliary air conditioning system. The test results show that the natural cold resources auxiliary air conditioning system is running well, practical, strong practical significance to the development of natural the Cold resource auxiliary air conditioning system in the northern region.
