Integrated split heat pump system for building applications

In this paper, a design of a specific hybrid energy system is elaborated for small scale applications in building facilities of residential or commercial purpose. The energy system is assembled from existing market available technologies that include implementation of a heat pump technology, photovoltaic system and of a standard accumulation boiler for the preparation of hot water. The developed energy system is assumed to be used in mild climates where a heat pump system can be efficiently used throughout the year. According to the gained experimental results the coefficient of the performance for the cooling mode can be expected between 5.0 and 6.0, which prove that the proposed system is highly energy efficient. The developed energy system can cover both cooling and heating demands and also demands for domestic hot water and it represents a totally renewable energy system.
