Design of a low-cost active and sustainable autonomous system for heating agricultural greenhouses: A case study on strawberry (fragaria vulgaris) growth

Parametric Analysis of a Radiant Gas Heating System for Controlled-Environment Agriculture with Preheated Ventilation

“…The choice of artificial heating methods for buildings and structures is only part of the energy conservation solution [9,13,[17][18][19][20][21][22]. In conjunction with this, there is a need for optimal architectural and planning solutions [15,[23][24][25][26][27][28], and the implementation of modern innovative technologies aimed at reducing the consumption of non-renewable fuel and energy resources [24,[29][30][31][32][33]. Therefore, within the context of addressing this problem, research on the impact of various factors on the energy balance of cultivation structures is required, consequently affecting the thermal regime of the premises and the calculated power of the adopted heating system.…”

Impact of Environmental Factors on Indoor Air Temperature in Gas-Fired Radiant Heated Cultivated Structures

“…In addition to the mentioned traditional heating systems, alternative methods for providing thermal comfort to cultivation structures are organized, such as through heat pumps [1,15] or solar collectors (solar greenhouses) [2,6,[10][11][12][13][14]. Currently, for several reasons [3]: artificial source of infrared radiation; the absence of the need for a boiler installation, thermal networks, and related engineering equipment; automation of the technological process; even distribution of thermal energy on the soil surface; possible application of carbon dioxide (CO2) for plant fertilization, obtained from fuel combustion products when using gas infrared emitters -gas radiant heating systems are of significant interest in agriculture [16][17][18][19][20][21][22][23][24][25]. To predict, maintain, and control the thermal regime of cultivation structures, the ability to calculate all incoming and outgoing heat and mass flows from space is required.…”

“…This study aims to investigate the influence of various factors (external and internal) on the air temperature inside a cultivation structure under gas radiant heating conditions. Addressing this issue will, in the future, enable the anticipation of potential fluctuations in air temperature relative to the required value and, consequently, safeguard cultivated plants from potential diseases and mortality [5,6,25].…”

Optimization of above-ground environmental factors in greenhouses using a multi-objective adaptive annealing genetic algorithm

“…These studies utilized the greenhouse environment model to quantitatively describe the interaction and relationship among the internal and external greenhouse environments, crops, and control equipment. Specific models have been developed to incorporate various factors, such as those solely considering temperature [ 6 ], combined temperature and humidity [ 7 , 8 ], and models estimating energy and CO 2 and H 2 O consumption, which are integral to calculating production costs and thus crucial for greenhouse design and environmental regulation [ [9] , [10] , [11] , [12] ].…”
