| This paper studied characteristics of Gas Driven Heat Pump and Water Source Heat Pump, as well as current research conditions of these two kinds of heat pumps. Then, this paper proposed the concept of Gas Driven Water Source Heap Pump(GWSHP), defined the research object. Following with these studies, this paper founded the math model of these two kinds of heat pumps, used Matlab to simulate each working condition and then got the useful curves.Since GWSHP is a new kind of cold and hot source, currently, there is no this kind of machine in the market, there is no testing data to testify the rightness of this kind of heat pump. Therefore, we founded the math model of Gas Driven Air Source Heap Pump(GASHP) which are founded based on the similar principle. According to the comparison between the result and testing data, we testified the rightness of the math model of GASHP, furthermore, we could advance the rightness to GWSHP in a certain distance. By this way, we could fathom the performance of GWSHP.Finally, this paper did economical analysis for GWSHP and other kinds of cold and hot sources, we found that to this kind of building and district, GWSHP had very good economical capacity as a kind of cold and hot source.
