Abstract

GHP system utilize national gas as a heat source. It reduces electric peak demand in summer and maintains a constant performance in winter by recovering the waste heat from the engine. Although the initial investment cost of GHP is higher than that of EHP, the overall operating cost of GHP is cheaper than of the EHP. In this study, items for dissatisfaction were summarized based on the results of user questionnaire(200 users), and field tests were made for 10 GHP installation places. The measured COP was estimated much lower than the rated COP by the manufacturer mainly due to partial load operation.
