“…The photovoltaicthermoelectric cooling system consists of four modules, a DC battery (12V, 80Ah), a photovoltaic cell, a charger controller, and an invertor. The hourly variation of the solar radiation on the horizontal surface outside reaches 1000 W/m 2 [54]. Each thermoelectric cooling module consists of four axial fans, three heat sink units, and two thermoelectric plates (12.3V).…”

This work presents the COP and EER of the combined air conditioning and thermoelectric cooling systems. The small-scale air conditioning (8000 BTU/hr) with thermoelectric cooling systems is set up in the closed room (2.0*2.0*2.0 m), and free energy from the photovoltaic cell is used for the thermoelectric cooling module. The COP and EER with the thermoelectric cooling module are higher than those without the thermoelectric cooling module. It is observed that the COP and EER increase as the axial fan speeds increase. In addition, there is good agreement from the comparison, giving an average error of 3.77%. The highest COP and EER for the system with the thermoelectric cooling module are 1.71 and 5.85 for an airflow rate of 4.7 m3/s, respectively. The results can be used as guidelines for developing the thermal performance of air conditioning by combining it with the thermoelectric cooling module.

“…The results showed that the drying rate increases with a decrease in mass flow rate. Vengsungnle et al [12] investigated the thermal performance of photovoltaic ventilated mixed-mode greenhouse solar dryer for ganoderma drying. It was concluded that mixed-mode solar dryer improved the drying rate and improved with increased ventilation and higher drying temperatures.…”

Solar drying is useful in several residential, commercial and industrial applications. Proper dryer design, operation and maintenance are essential for enhancing the dryer performance and better quality of the dried product. Solar dryer is beneficial as it protects the product from adverse climatic conditions and quickly economically dry the product. The dryer design has undergone significant shapes, dimensions, and storage features leading to better reliability. Researchers worldwide have reported higher energetic and exergetic performance through advanced design, measurement, and control features. Conventional dryer’s efficiency deterioration is attributed to the lack of proper material selection and computational fluid flow techniques. Traditional dryer designs have focused on product drying rate while advanced sustainable solar dryer designs increased solar thermal utilization in a limited area with locally available materials based on fluid flow conditions suitable to the microclimatic conditions. Analysis using computational fluid dynamics (CFD) software has assisted in refining dryer designs to be compact with the complex flow and quick product drying features. The present paper tracks developments in solar dryer designs for different dryer classifications. Recommendations for energy-efficient design and measures for improvement in existing dryers are also discussed.

“…They claimed that the developed SGHD results in a considerable reduction in the drying time with a saving value up to 67% compared with the open-sun-drying. In another study by Vengsungnle et al [96], the energy analysis of a PV-ventilated mixed-mode SGHD with automatic closed-loop control for drying of Ganoderma was investigated and the obtained results were compared with the open-sun-drying process. The results indicated a considerable effect of the ventilated frequency and drying temperature on the evaporating moisture of the Ganoderma.…”

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.
