Energy-saving installation for heating and cooling livestock premises using geothermal energy

Abstract

Abstract The article considers the calculation of the main design parameters of a geothermal air cooling system in livestock premises, which, unlike traditional systems, do not use fossil fuels to generate heat. They simply take energy from the soil, while, as a rule, electricity is used only for the operation of fans, compressors and pumps. The purpose of the study is to reduce energy consumption when creating the technologically necessary temperature and humidity conditions in premises by using the cold of the earth’s strata. The calculation of the heat exchanger installed inside the livestock premises is reduced to the choice of design and energy parameters of the surface heat exchanger of the cooling unit, as well as to the determination of the flow rate of water passing through the heat exchanger. Water cooling is done in a heat exchanger buried vertically in the soil (the so-called probe). The probe is a plastic pipe lowered into the well and filled with a special filling with good thermal conductivity. The article presents the calculation of the probe length, since this parameter of the heat exchanger-probe is the main parameter of the installation.
