This paper is focused on the energy performance evaluation of Gas Engine Driven Heat Pump (GHP) and Electric Heat Pump (EHP) in accordance with the conversion factors for primary energy and secondary energy. Generally, primary energy of gas consumption is lower than that of electric consumption due to different conversion factors.
For this study, we measured actual energy consumption for a target building in which GHP was installed with outdoor unit as HVAC system. The measured data was compared with simulated results from EnergyPlus developed by Department of Energy in USA. As a verifying results, the mean bias error and the root mean squared error of gas consumption were -0.19% and 10.5%, respectively.
When we applied electric charge for general building, the cooling operating cost of the EHP was more expensive than that of the GHP in the building. However, operating cost of EHP showed lower than operating cost of GHP when we applied electric charge for the educational building due to reduced charge in accordance of building purpose. Even though the primary energy use of EHP was more used than that of GHP by 27.2%, secondary energy of GHP was higher than that of EHP by 42.6%, because the EHP has high-performance of COP 3.59 compared with the GHP performance of COP 1.13. Therefore, it is desirable to use gas for cooling energy of in a target building for primary energy.
