The Technical And Economic Study Of Ice-storage Air-condition System

Ice-storage air-condition system will improve the energy coefficient of utilization and optimize energy resource disposition , which is an important measure to realize the "shift peak load to low period" of electrical wire and is also a main orientation for modem air-condition development. So, it is of realistic significance to make a technical analysis about ice-storage air-condition system.In order to economize the electricity cost, the initial investment will be increased in ice-storage air-condition system. The economical analysis model on regular air-condition system and ice-storage air-condition system is established in my thesis and technical analysis is made on this model, which proves that the engineering application of ice-storage air-condition system will achieve favorable economical benefit if the design model and operating tactic are properly chosen.Whether the ice-storage air-condition system is applicable or not depends on whether the increased investment can be called back in a short time, which in turned determined by the running planning design. The paper deals with several factors that will influence the how many years the investment can be called back, and at the same time, discusses the best choice of operating strategy of ice-storage air-condition system and refrigeration compressor capacity, pointing out that the local electrical price plays a crucial role in ice-storage air-condition system .This paper researches the exergy analysis of ice-storage air-condition system, discovering the distribution and causes of exergy loss in the system to point out a way for system energy economization.On the basis of economy of ice-storage air-condition system, I have designed the ice-storage air-condition system software. It will provide convenience for the engineering staff in field of air-condition design and calculation to some extent.
