    Solar air systems (the systems where air is used as a heat carrier) are not as common as the water-based solar systems. Nevertheless, the solar air systems can be used in many applications including space heating of buildings. A general problem with the solar thermal systems is the need for thermal storage in order to balance supply and demand of heat over a certain period of time. A possibility to employ phase change materials (PCM) for such thermal storage was investigated using numerical simulation. A numerical model of the heat storage unit (air-PCM) was created as a type in the TRNSYS 17 simulation tool. The heat storage unit consists of aluminium containers filled with a PCM. The model allows specification of the thermo-physical properties of the PCM as well as other parameters. The results obtained from the numerical model will be validated by experiments performed on an experimental set-up that is currently under construction.

    A front-and-back-pass solar air collector was chosen for the numerical analysis because it offers higher heat exchange area than the front-pass or back-pass configuration. The results are presented and discussed in the paper.

    SIMULATION OF LATENT-HEAT THERMAL STORAGE INTEGRATED WITH ROOM STRUCTURES,

    The phase change of a material is accompanied by a release or absorption of a considerable amount of heat. That makes a phase change a phenomenon effectively usable in various thermal storage applications. There are many materials with a melting temperature lying within the thermal comfort range for indoor environments. These materials can be utilized in building-integrated thermal storage. The performance of such latent-heat thermal storage integrated with the room structures was investigated through numerical simulations and experiments. The studied case involved two adjacent rooms of the same dimensions. The hydrated-salt-based phase-change material (PCM) was used as a thermal storage medium. A comparative approach was adopted in which the internal structures of one of the rooms contained the PCM, while the structures in the other room did not. The simulation model of the rooms was created in the numerical simulation tool TRNSYS 17, and this model was coupled with a PCM model created in MATLAB. The enthalpy method was used for the simulation of the phase change. This approach allowed for different time steps in the room model and the PCM model (the time step in the PCM model needed to be much shorter). The data from the real-scale experiments (ventilation rates, temperature of supply air, outdoor temperature, solar radiation intensity, etc.) as well as the physical properties of the PCM acquired in the laboratory testing were used as inputs to the simulation models. The analysis of the results was carried out, in which the simulation results were compared with the experimentally obtained data.
