  • Ventilation system with heat recovery and PCM thermal energy storage for "free" cooling in buildings [Elektronski vir]
    Jocić, Anastasija ...
    For the conventional cooling of buildings, we are using electrical energy from the network, which increases annually due to the increase in comfort. Alternatives are being sought to reduce ... electricity consumption. Phase change materials (PCMs) in ventilation systems can provide us with the accumulation of night-time coolness in the summer months, resulting in a reduction in the consumption of electricity for cooling. Heat storages that take advantage of the phase change are used for short-term storage of thermal energy, as in this case, they have the greatest potential. In the introduction to the paper, a review of heat storage devices and their use is made which shows their connection with the Energy Performance Building Directive (EPBD) and the Energy Efficiency Directive (EED). Based on the measured results of the measurements in the Laboratory for Heating, Sanitary and Solar Technology and Air-conditioning (LHSA), a comparison with the model that calculates the storage of heat and cold in a phase change material (PCM - Phase Change Material) developed by a group of researchers from BUT Brno was made. With the TRNYSY software tool and the model simulations of the ventilation gains in the summer season were made and compared with the gains when using the heat exchanger (recuperator) and the PCM heat accumulator for the selected room.
