Solar-ice systems for multi-family buildings: hydraulics and weather data analysis

Dynamic simulations using the TRNSYS environment were used to assess the potentials of solar-ice systems for multi-family buildings in Switzerland. The goals of this paper were: i) to analyze and quantify the effects of different hydraulics in the primary loop (solar collectors, ice storage and heat pump), ii) to determine the energetic performance of solar-ice systems for multi-family buildings and iii) to assess the influence of the chosen weather data on the system performance. Simulations were carried out for a range of collector areas of 1.5 m²/MWh to 2.5 m²/MWh and for ice storage volumes of 0.4 m³/MWh to 0.6 m³/MWh being MWh the total yearly heat demand. Simulations of eight cities in Switzerland using cold, warm and normal weather data sets from SIA were carried out.
