Original Abstract

Phase change materials (PCMs) are materials with a high latent heat of melting. The PCMs can be used in various thermal storage applications. One of them is thermal storage in solar air systems. The air-based solar thermal systems are not as common as the water-based solar systems but they can be rather effectively employed for space heating and other purposes. 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. This can be solve by using unit comprises of aluminum containers filled with paraffin-based PCM. In this paper is described both, the numerical simulations and the experimental investigation of an air-PCM heat storage unit. The simulation is based on coupling between the TRNSYS 17 and the MATLAB. The experiment contains laboratory heat exchanger which comprises 100 PCM panels. Both results are compared in order to validate numerical model. The results prove that use of the PCM in the heat exchanger has significant heat storage effect.
