Special Issue Information

Dear Colleagues,

Solar thermal systems comprising collector and storage tanks at the same unit belong to the category of low-cost solar devices that mainly cover needs for domestic applications. The development of these systems has been discussed in detail in several works in the last two decades. Among these works, there are some of great interest, combining techniques as vacuum and/or phase change materials (PCM). The scope of this Special Issue is to present recent advances in the development, design, production, and study, either theoretically or experimentally, of advanced solar thermal systems with the above characteristics. Of special interest will be the environmental impacts and life cycle assessment of these systems.

A Study on Developing an Automatic Controller with an Inverter Collector Pump for Solar-Assisted Heating System
Energies 2020, 13(9), 2128; https://doi.org/10.3390/en13092128 - 27 Apr 2020
In this study, based on the optimal equation m=0.05ΔTAc (kg/min) of the variable mass flow rate in the collector loop, an automatic controller with an inverter collector pump for the collector loop of the solar-assisted heating system [...] Read more.
In this study, based on the optimal equation m = 0.05 Δ T A c (kg/min) of the variable mass flow rate in the collector loop, an automatic controller with an inverter collector pump for the collector loop of the solar-assisted heating system is designed for these experiments and to then be used for real industry. The pump for the collector loop is an inverter type that is controlled by an embedded controller with Windows, based on C# language, and the change of speed depends on the variation of the mass flow rate through the collector loop. The input of the automatic controller with an inverter collector pump is given by a thermocouple input module that is connected to the embedded controller with the RS-485 communication protocol. In this work, the experiments were carried out on three different days, namely a clear day, an intermittently cloudy day and an overcast day, to evaluate the stability and the precision of the automatic controller, as well as the contribution of the useful heat gain from the collector for the solar-assisted heating system. Simulation and experimental results are also validated and analyzed. Full article
