Energy-Independent Heating System with Improved Energy Efficiency for Agricultural Premises

Introduction. The article is concerned with increasing the efficiency of energy-independent heat supply systems in agriculture through using a recovery unit thermomechanical energy converter. most promising converter thermodynamic cycle periodic action to drive diaphragm pump. For heaters and boilers, use pulsating mode carrier has double effect: it increases transfer reduces formation deposits on surfaces. Materials Methods. Using method possibilities impulse technologies, device were proposed. In this device, three processes are sequentially implemented: isochoric heating evaporation working substance, adiabatic performance work, isobaric condensation. Thermodynamic cycles constructed for five known substances (R11; R21; R113; R114; R123) lgP-h state diagrams their parameters at characteristic points calculated. Results. There been performed frequency matching thermal-mechanical hydraulic source heat-consuming unit. Such was based responses. To describe hydrodynamics system, system differential equations constant coefficients used, which solved Laplace transformation. A rational oscillations flow determined within range 1.38–2.76 rad/s. Discussion Conclusion. scheme independent connection On example power 100 kW, graphical dependences minimum pressures change consumption active resistance network obtained. An algorithm determining increment from exchanger It that will be higher low-power boilers.
