Abstract

This paper deals with the analysis of a specific HYS (hybrid energy system) from an overall energy ef-ficiency aspect and also from an economical aspect. The hybrid energy system was purposely assembledfrom standard, market available energy technologies that are presently used in majority of buildingfacilities, particularly in residential ones. Based on the previous aspect, the HYS was assembled using astandard split heat pump system (air-conditioning unit) with an integrated accumulation boiler for hotwater preparation and using a small PV (photovoltaic) system. An overall energy efficiency analysisshowed the HYS system to be highly energy efficient on average as overall energy efficiency ranged from50% up to over 200% (the heat pump system acts as a kind of efficiency booster). An LCOE (Levelized costof produced energy) analysis showed that the HYS produced energy cost ranged from 0.035V/kWh up to0.15V/kWh, in correspondence with overall working time, the average coefficient performance achievedby the heat pump system and in investment conditions. A detailed energy efficiency and feasibilityanalysis showed that the herein analyzed HYS can be a viable option for small or medium buildingapplications in mild climates.
