Parametric and numerical study of a solar system for heating a greenhouse equipped with a buried exchanger

Thermal performance of a radiant floor heating system with different heat storage materials and heating pipes

“…Their simulation results suggested that the system can achieve a thermal COP higher than 1.0 and an electric COP about 8.0. Attar et al [27] used capillary mat as buried heat exchanger in a solar system for heating a greenhouse and results of their parametric analysis showed that the inside air temperature of the greenhouse can be increased by 5°C. Mikeska and Svendsen [28] numerically investigated the thermal performance of capillary mats integrated into the building sandwich element made of high performance concrete and did a detailed parametric analysis such as the effect of different circulating fluid temperatures, spacing between capillary tubes and panel thickness, etc.…”

Development and Optimization of a Building Energy Simulation Model to Study the Effect of Greenhouse Design Parameters

“…Carlini et al [10] verified the feasibility of a "photovoltaic greenhouse" and further analyzed the influence of the climate outside the greenhouse, the choice of plants cultivated, the choice of construction materials, wind conditions, altitude, and slope exposure on energy balance. Attar et al [11] also presented a greenhouse solar heating system, discussing the parameters that influence seasonal storage systems. Vadiee and Martin [1] studied feasibility of the evolution of solar energy to fulfil the energy demand of greenhouses, discussing options to minimize energy demand and maximize the utilization of solar energy.…”

Parametric performance analysis of a concentrated photovoltaic co-generation system equipped with a thermal storage tank

“…To investigate the dynamic behavior of a flat-plate solar collector, researchers performed a transient numerical analysis by varying different parameters that affect the collector performance [7]. For the maximal use of direct radiation [8], the solar concentrated system should be subjected to parametric performance analysis, and the energy requirement for the specific application should be predicted accurately. A concentrated solar energy system can perform optimally if the heat losses are reduced through the selection of appropriate design and operating parameters.…”
