摘要

Regulation of the thermal regime of the soil in greenhouses assumes particular urgency in light of the need to remove excess low-potential heat from thermal power plants. In this paper, a method for analytical calculation of heat removal from a sphere immersed in the ground of a greenhouse is developed. Based on the calculation, dependences of the specific heat flux are constructed on changes in the following parameters: ambient and soil surface temperatures, depth of occurrence and diameter of the spherical body, coefficient of heat emission from the ground surface to air, and thermal conductivity of the soil. This mathematical model can be used to predict the temperature regime of the soil during subsoil heating.
