Dolgikh D. Substantiation of the parameters of the soil heat exchanger for livestock buildings

The scientific task for creating the regulatory conditions of the microclimate in livestock build-ings by the way of substantiation of the constructive and technological parameters of the geothermal ventilation was solved in the dissertation. The influence of the microclimate parameters on animal per-formance was analyzed. The research of the existing the technologies and the technical means for ex-tracting thermal energy from the surface layers of the soil for provide a microclimate in the livestock buildings was performed. The improved technological scheme of the geothermal ventilation for live-stock buildings has been proposed. The theoretical studies were allowed to establish dependency of the effective thermal power of geothermal ventilation from its geometric parameters. Length and diameter of the working body of the geothermal ventilation - the vertical ground heat exchanger was theoretically grounded. The mathematical model of the change of effective thermal power of the geothermal ventilation depending of the distance intercentral axes of the ground heat exchangers for the location in a one row was of-fered. As a result of experimental studies the dependence of the influence of constructive and techno-logical parameters of geothermal ventilation on its thermal power was received. The optimal parame-ters and operating modes of the geothermal ventilation for livestock buildings were substantiated. The technical and economic feasibility of the application prototype of the geothermal ventila-tion for livestock buildings were substantiated.
