Abstract
In respect of global environment protection and efficient utilization of energy, co-generation systems, which have greatly higher efficiency than the other generations, have been developed and put to practical use. Assuming that the co-generation system would be operating in H-Department of Kwang-ju city, this paper calculates the difference between the heat and electricity rates by the conventional method and the co-generation system considers the cost of new investment and analyzes introduction economics based on the return on investment. The introduction is turned out to be recommendable, since the return of investment for co-generation equipment is about five years when the co-generation profits in heat and electricity rate. Additionally, accounting for interest rate drop, improvement of environmental matters or electricity rate increase, it is shown to be even more economical.
