The Research Of Cold Energy Recovery Used In The Air Conditioning System Within Their Own Buildings In Satellite LNG Gasification Station

In recent years, liquefied natural gas (LNG) as a kind of clean energy, is convenientfor storage and transportation, to accelerate the development of the natural gas in Chinaplay an actively promoting role, then the peak for the construction of satellite LNGgasification station is coming. The gasification of LNG can generate a lot of cold energy.But by the limitation of factors such as its scale, geographical location and thedownstream industry chain, there are few practical cold energy utilization projects intosatellite LNG gasification station. So the research for cold energy utilization has a posiverole to save energy and the very good practical economic significance, at the same time, itwill become a hot problem in the research of LNG technology.The paper, based on the study of satellite LNG gasification station, use the energy(exergy) to analyze the factors of LNG gasification process. And analyze itselfcharacteristics, the problems existing in the cold energy utilization and the matters needingattention. Combined with the surrounding environment and economy factors such asmarket potential, this paper analyze all kinds of cold energy utilization by its advantagesand disadvantages.In this thesis, the cold energy recycling can be used to the air conditioning systemwithin their own buildings, in order to achieve the purpose of saving energy. Based on theoriginal gasification process, building a cold energy recovery system. Analysing each linkin system and the necessity of setting tank and determining the type of heat exchanger.chase for LNG gasification and building their independence between the hourly coolingload, mainly analyzes the operating strategy of the system under different workingconditions, the operation mode of the heat exchanger is studied. Then focuses onanalyzing the operation of the system under different working condition of strategy.Finally, this thesis use a satellite LNG gasification station participated in the designas an example for analysis, using the energy consumption simulation software DEST tosimulate the building cooling load. And analyzing different operation condition andoperation strategy.by using the actual data of loadThis article build a cold energy recycling utilization system for satellite LNG gasification station, it provide a good choice for cold energy recycling utilization andprovid theoretical basis and play a certain guiding role.
