AB  - Energy costs are rapidly rising around the world and it is important to find a way to reduce energy consumption. Energy consumption in buildings can account for up to 40% of total energy consumption in developed European countries due to an increase in living space per person, an increase in the need for air conditioning, an increase in the number of appliances used in households, and other factors. Due to the increasingly frequent high temperatures during the summer and the increase in electricity consumption, it is very important to find a way to decrease indoor temperatures in urban residential buildings without using more energy, given the severe energy crisis that has engulfed Europe and the high percentage of energy and electricity consumption in the residential sector. Installation of phase changeable materials is one method for improving the thermal envelope of a building by increasing the thermal capacity of the envelope and thus affecting the reduction of indoor temperature oscillations and, consequently, reduction of summer electricity consumption. In this study, the TRNSYS software package was used to simulate and compare the indoor air temperature in typical detached houses built in period 1946 and 1970 in the Belgrade area, for both, the case without and the case with installed phase change (PCM). It was shown that incorporating a PCM with a melting temperature of 25?C into the inter-floor construction of the house could significantly improve comfort conditions by reduce indoor temperature fluctuations during the warm period without consuming additional energy. When the temperature outside is around 30?C, the maximum air temperature in the house drops by about 2?C.

AB  - Phase change materials (PCM) are attractive energy storage technologies due to their high energy storage density and the ability to reversible absorb and release thermal energy at a nearly constant temperature. Polymers and polymer-based eutectic mixtures are promising PCMs. This study aims to investigate heat properties (melting temperature (Tm), latent heat (ΔH) and thermal conductivity(λ)) of potential PCMs based on polyethylene glycol polymer (PEG2000). We prepared following two and three components materials: PEG2000: ethylene glycol (5:6): PEG2000: PPG 400 (1:5); PEG2000: PPG400: Choline chloride (2:2:15); PEG2000: ethylene glycol (5:6); PEG2000: Glyoxal (5:2). The prepared three components material belong to deep eutectic solvents. Tm of the prepared materials are lower compared to pure PEG2000 (Tm = 57 ºC) e.g. Tm of PEG2000: PPG400: Choline chloride is 43 ºC. The determined melting enthalpies are also lower for prepared materials compared to PEG2000. This decrease is lower for eutectic mixture such as PEG2000: Choline chloride: ethylene glycol. We can conclude based on the obtained result that eutectic mixtures based on polymers are promising PCMs.

AB  - Incorporating phase change materials (PCM) into building structures as passive latent heat thermal energy storage technologies offers a potential solution for reducing energy demand and regulating thermal comfort in occupied buildings. Integrating PCM into lightweight walls can improve their thermal performance by increasing building heat capacity and decreasing energy consumption. The effects of phase change materials (PCMs) added to the thermal envelope of lightweight residential containers on building thermal comfort are investigated in this study. The simulations were run for the summer period because it is difficult to achieve thermal comfort without using a lot of energy at that time. Thermal comfort is highly dependent on both, climatic conditions and the materials used to construct the building's thermal envelope, and the simulation was performed for weather conditions in five different geographic locations using TRNSYS simulation software. The paper examines the effects of PCM on indoor air temperature, specifically on reduction of maximum air temperature and temperature fluctuations

AB  - Due to the excessive use of air conditioners and heating systems, energy consumption by the builiding sector has been growing significantly in recent years, which leads to the accelerated depletion of conventional energy sources and to the fact that renewable energy sources are becoming more and more popular. Phase change materials are suitable for use in latent heat energy storage technology due to their high storage density and stable thermal properties. The thickness of phase change materials (PCMs) added to the thermal envelope of a lightweight building is investigated in this study. The simulations were run for 7 days in July, which was determined to be the hottest period of the summer based on the Meteonorm weather file, and when it is difficult to maintain thermal comfort without using a lot of energy. The thermal behavior of the building without PCM and with builtin PCM in the envelope of the building in one wall on the south side and on the ceiling, with different thicknesses of phase-changing material was simulated and the results obtained were analyzed with the aim of establishing which thickness of phase-changing material is optimal for installation in the envelope of the building

AB  - Using solar energy for drying agricultural products is one of the oldest methods of preserving food. Excellent results are obtained by using solar dryers, both in the quality of dried products and in energy-efficient drying procedures. The problem occurs when the solar radiation is low intensity or absent, which makes it impossible for the solar dryer to work. This problem can be solved by implementing phase change materials (PCM) which improve the efficiency of the system and allow the dryer to work in a period during off sunshine hours. This review provides insight into the progress in the field of solar dryers in which PCM is implemented. The impact of using PCM on the quality and efficiency of product drying compared to solar dryers without PCM and open sun drying is shown. It has been noticed that the use of PCM improves the global thermal efficiency of the system. The temperature and the percentage weight of moisture removal was increased and the drying time of the product was reduced. Various cases of drying apples, tomatoes, basil, bitter melons, strawberries and medicinal herbs have been considered. Different positions of PCM in flat solar collectors increased the thermal efficiency of the flat plate collector in the range from 5.02% to 10.13%, and the overall efficiency varied from 21.92% to 25.72%. The use of hybrid systems consisting of two or more synchronized systems also have been considered. The hybrid solar dryer with implemented PCM and integrated geothermal system showed an improvement in performance efficiency of 20.5% compared to a flat plate solar collector. The progress of solar dryers with the implementation of PCM is given with the aim of further developing the application of renewable energy sources in food preservation.
