“…The simulation of the phase change was realized by the ANSYS Fluent solidification and melting tool. The solver settings were designed according to Al-abidi et al [3] and Nayak et al [4]. To solve the simulation the pressure-based Navier-Stokes solution algorithm with the absolute velocity formulation was used.…”

This work deals with the optimization of the icing process in an ice storage system. It is focused on the improvement of the icing behavior, which is to be achieved by different heat exchanger geometries in the ice storage tank. Therefore, CFD simulations were implemented to acquire and visualize the flow conditions, the temperature behavior and the growth of the ice layer during the cooling process. The results are compared and validated with model experiments on an experimental ice storage. It could be shown that the heat extraction of current technologies can be increased by more than 50% by using geometries that are more efficient.

“…A first TES closed sorbtion prototype based on sodium hydroxide was developed in the EU COMTES project. Investigations have shown a lower efficiency compared to the theoretical value during the absorption phase (storage discharging) (Daguenet-Frick et al, 2014). This was explained by a poor wetting of the A/D (Absorber/Desorber) tube bundle (AISI 316L) with the concentrated, viscous sodium lye and its short residence in the water vapor.…”

An increasing population with the need of new buildings in combination with global warming is important issues ahead. Hence, for defining a clear path towards a low and zero-emission building stock in the EU by 2050, as recently stated by the new EPBD recast, Nearly Zero Energy Buildings are one of many necessary measures for climate change mitigation. Finding cost optimal solutions are important, where a short time perspective and narrow concept for evaluation may be wrong. This study presents a Net Zero Energy Building in Sweden, with verified plus energy performance in the operation phase. Furthermore, it presents an economic analysis, based on life cycle costing (LCC), where additional cobenefits are included. The study shows that the discounted, cumulative annual cost reductions due to energy savings may exceed the initial extra costs after more than 20 years. However, when including additional green values and increased property value, breakeven may occur already after roughly five years.

“…Operation of an production, PLC which is the key that is widely using tool in an industries to control and read the entire process of the plant; while in running condition of the PLC ladder program the changes in the rungs are understandable by a skilled engineer only others cause difficulties to understand the operation. So that SCADA system is implementing, through that the changes in the operation and process are easily understandable to a Client, by the differentiation in color of the motor, valves, filling of liquid in pipes and more are visible to all so that less skilled operator can also be control the plant [1][2][3].…”

The electrical output decreases in the PV system due to the heat generation in photovoltaic (PV) cell. The part of PV heat formation can be removed through attachment of phase change materials (PCM) at rear side of the ethylene vinyl acetate (EVA). The paper explains the Temperature distribution in the PV modules and analysis was done with and without PCM in two different weather conditions. Then the PCM (Calcium chloride hexa-hydrate) is connected on the PV panel rear side to evaluate the different solar irradiance levels. In Literature it is observed that the heat removal of PCM capability is used to control the generation of heat of the PV system. Thus the current work is to investigate the effects of PCMs in photovoltaic cell which reduces its temperature and also the thermal response of PV-PCM system and various weather conditions are analysed.
