“…The final part of this study concentrated on the exergoeconomic assessments and offering some economic suggestions. The modeling results were validated with measured values from the constructed greenhouse of 15 2 . The results of this project can be used in commercialization of the semi-solar greenhouses in the future and help farmers and customers by decreasing the crop cost.…”

“…They showed that coupling the conventional fossil fuel based systems by the proposed solar collectors, notwithstanding longer payback period, are more efficient. Gorhian et al reviewed the development of solar greenhouses by considering their coupling with solar energy resources such as photovoltaic (PV), photovoltaic-thermal (PVT), and solar thermal collectors [2]. They concluded that solar thermal collectors installed at greenhouses in temperate climates had higher efficiencies.…”

This study deals with dynamic modeling and analyzing of an innovative semi-solar greenhouse s tructure applying MATLAB software from the viewpoints of energy, exergy and economic. This Modeling is applied to predict the temperatures of four different points inside the semi-solar greenhouse, regarding the evapotranspiration of the crop. Measured data recorded from the constructed typical semi-solar greenhouse is used to evaluate the results of the proposed thermodynamic analysis. Measurements during the experiment show considerable temperature difference of 20 ℃ between the indoor and outdoor air. The mean values of 5.94% and 2.06℃ for (Mean Absolute Percentage Error) and (Root Mean Squared Error) indicates the accuracy of the thermal simulation. Furthermore, in different heat and mass transfer processes, the total exergy destruction values are analyzed. The target of this research is considered as providing suitable environmental conditions for the inside of the greenhouse. In this respect, the greenhouse air unit cost for each time step of one minute is inspected. By increasing the interest rate from 10% to 20% the greenhouse air unit cost raises almost twice. Decrease of about 45.36 % in total exergy destruction is obtained by the technique of applying double layer glass as the greenhouse cover.

“…A greenhouse is employed very often for cultivating crops. In these structures, the desired microclimate is provided by supplying the required heating, cooling/ventilation, and carbon dioxide (CO 2 ), allocating almost 65-85% to provide heating and cooling demands [66]. According to the literature, the annual energy demand for greenhouse production is about 220-320 MJ/m 2 of the greenhouse area, mainly in the countries of Italy, Greece, and Southern France, with the value of 3600 MJ/m 2 in Germany, Poland, and the Netherlands [67].…”

The food industry is responsible for supplying the food demand of the ever-increasing global population. The food chain is one of the major contributors to greenhouse gas (GHG) emissions, and global food waste accounts for one-third of produced food. A solution to this problem is preserving crops, vegetables, and fruits with the help of an ancient method of sun drying. For drying agricultural and marine products, several types of dryers are also being developed. However, they require a large amount of energy supplied conventionally from pollutant energy sources. The environmental concerns and depletion risks of fossil fuels persuade researchers and developers to seek alternative solutions. To perform drying applications, sustainable solar power may be effective because it is highly accessible in most regions of the world. Greenhouse dryers (GHDs) are simple facilities that can provide large capacities for drying agricultural products. This study reviews the integration of GHDs with different solar technologies, including photovoltaic (PV), photovoltaic-thermal (PVT), and solar thermal collectors. Additionally, the integration of solar-assisted greenhouse dryers (SGHDs) with heat pumps and thermal energy storage (TES) units, as well as their hybrid configuration considering integration with other renewable energy sources, is investigated to improve their thermal performance. In this regard, this review presents and discusses the most recent advances in this field. Additionally, the economic analysis of SGHDs is presented as a key factor to make these sustainable facilities commercially available.

“…In addition to the above solar thermal collectors, PV/T collectors have good potential for solar greenhouses (Jouhara et al, 2016;Gorjian et al, 2021). Hybrid PV/T systems are combination of solar-thermal devices and solar-electric devices (Arefin, 2019).…”

Traditional agricultural greenhouses have been used to grow vegetables in the winter without any auxiliary heating. However, crop production is highly influenced by soil and air temperatures, humidity, and solar radiation. The aim of this paper is to review the recent active solar thermal technologies that help reduce the energy demand for greenhouse climate control and achieve intensive crop production. The review is categorized into the following topics: 1) locations for collector installation; 2) discussion on the different types of solar collectors, which include metal-based, glass-based, ceramic-based, plastic-based, and hybrid photovoltaic/thermal types for greenhouse applications; 3) heat release systems in active greenhouses in terms of basal heating, backwall heating, and air heating systems; and 4) short-term and long-term heat storage systems for greenhouses. Future studies on active solar greenhouses might focus on microclimate prediction, long-term heat storage, and system optimization.
