In the near future renewable energy driven heat pump systems will play an important role in the thermal management of buildings. The work described here deals with the effect of weather conditions as well as operational characteristics on the energy and economic performances of a solar PV powered air conditioning unit (ACU) with a battery system (PBAS) based on numerical and experimental investigations. The experiments were carried out to test the developed TRNSYS model. In the assessment various performance indicators were used while a novel performance indicator the so-called annual grid independence ratio was also proposed. The simulated studies revealed that annual energy performance indicators (self-consumption self-sufficiency grid independence and energy conversion ratios) are greatly affected by climatic conditions and operational characteristics. Besides the economic analysis has shown that the net present value and the energy consumption profiles or diverging values for state of charges are directly proportional for the hottest (Seville) climate. However they are inversely proportional for the coldest (Stockholm) climate for the considered PBAS configuration (PV-2.5 kWp ACU-2.52 kW cooling and 2.84 kW heating batteries-9.6 kW h) under the selected economic status of the sites. © 2022 Elsevier B.V.
