Investigation of heat transfer processes at a full-scale object in a fruit and vegetable storage with a natural cold ground accumulator

Abstract

This article studies the heat exchange processes between the natural cold of outdoor air and the soil battery in an experimental setup. In addition, the temperature field temperature between the surface of a reinforced concrete pipe with a diameter of d = 300 mm and the soil mass, the heat transfer coefficient, and the Fourier number were calculated and graphs were obtained. The accepted theoretical dependences for describing the processes of conductive heat transfer of a ground cold accumulator differ by 10-15% from the experimental data obtained on a physical model for various Fourier numbers.
