Heat pump systems are promising technologies for current and future buildings and this research presents the performance of air source heat pump (ASHP) system. The system was monitored, analysed and simulated using TRNSYS software. The experimental data were used to calibrate the simulation model of ASHP. The specific climate conditions are evaluated in the model. It was noticed for the heating mode that the coefficient of performance (COP) varied from 1.98 to 3.05 as the outdoor temperature changed from –7.0 ºC to +5.0 ºC, respectively. TRNSYS simulations were also performed to predict seasonal performance factor of the ASHP for Vilnius city. It was identified that seasonal performance prediction could be approximately 15% lower if frost formation effects are not included to air-water heat pump simulation model.

This article gives an overview of the study on using the air-to-water heat pump (A&WHP) for heating buildings in cold climate regions. The study was conducted in a relatively cold region (59°N), where the ambient temperature during the winter usually falls below-20°C. Despite the fact the COP of the air-to-water heat pump in the winter period was 2.5 on average and during the heating season of 2013/2014 the additional energy requirement was less than 3%.
