Статья: Математическая модель лучистого отопления теплицы (2026)

To maintain favorable conditions for plant growth in protected soil during the cold season, coordinated operation of heating and irrigation systems is required to ensure an optimal microclimate of the greenhouse. The choice of a heating system, in particular autonomous radiant systems based on dark-type ceiling gas infrared radiators, has a significant impact on the thermal regime of the soil and the parameters of the air environment. The purpose of the study is to develop a mathematical model of heat and mass transfer in a greenhouse using radiant (infrared) heating under irrigation conditions, designed to justify the required thermal capacity of the heating system and calculate the optimal mass flow of water for irrigation during the cold season. The mathematical model includes the air environment, the soil surface and the enclosing structures of the greenhouse, and also takes into account the radiant heat transfer in the “radiator → soil ↔ enclosure” system. A formula is proposed for determining the coefficient of multiple reflection of infrared radiation, which makes it possible to calculate the resulting heat flux absorbed by the soil surface.
