ECONOMIC ANALYSIS OF HEAT PUMP SYSTEM FOR UNIVERSITY FACILITYES IN KOREA
The present study has been conducted economic analysis through actual operation of EHP and GHP which are installed at the same building of an university. Cost items, such as initial costs, annual energy cost and maintenance cost of each system are considered to analyze LCC and economical efficiency is compared. The initial costs are considered on the basis of actual costs, and annual energy cost is converted into the cost after measuring electricity and gas consumption a day. LCC applied present value method is used to assess economical efficiency of both them. Variables used to LCC analysis are electricity charge escalation rate, natural gas cost escalation rate, interest rate, and service lives and when each of them are 4％, 2％, 8％, and 20 years, results of analysis show that EHP (148,257,306 won) is 8.05％ (12,981,990 won) more profitable than GHP (161,239,296 won).
