Modeling and optimization of the parameters of the heat accumulator of the combined livestock-heliogreenhouse complex

Abstract

In the article, the heat exchange process in the water tank battery, which acts as a wall between the livestock building and the solar greenhouse, is studied. The division consists of parallelepiped-shaped tanks, between which the coefficients of heat transfer in charge and discharge mode are determined, taking into account the different temperatures and speeds of the air in the livestock building through the air-moving corridors. A mathematical model of the temperature regime was developed based on the balance equation of the water tank accumulator. The geometric dimensions of the water tank accumulators are optimized based on the criterion equations. A computer model was created using the COMSOL Multiphysics software tool and thermal efficiencies were determined. Based on the results of the conducted research and numerical calculations, it is based on the high heat exchange and energy efficiency when the size of the water tank accumulator is 40x60x25 cm.
