According to the energy-level features of cold energy from gasification station

not only the mode of utilizing such cold energy at refrigerated warehouse was analyzed

but also the various system process flow and corresponding features of such cold stores was compared in this paper.Under certain assumed conditions

the technological and economic analysis of the third flow mode was made by taking a gasification station with the gas supplying capability of 4×107 m3 per year as an example.Results indicate that under a 33% cold energy reclaim ratio of the refrigerated warehouse

the annual profit from available reclaimed cold energy of the gasification station is 6.113 million CNY

and the operation cost of the refrigerated warehouse under this mode is low.Therefore its payback period is no more than a year and economic benefits significant.
