“…Previous works of the authors were also devoted to modeling the thermal state of the heat storage elements of the electric thermal storage (ETS) [9] and calculating the thermal characteristics of the ETS [10]. The results of experimental studies of the thermal state of heat storage elements in the heat charging and heat emission operation modes of ETS are presented [11]. Patent search on the websites of the Eurasian Patent Organization, as well as Rospatent and Google patents was used to analyze existing developments in this field of study.…”

An analysis of scientific studies has been carried out, which presents thermoelectric technologies based on solar energy that can satisfy not only the need for electricity generation, but also contribute to energy saving and environmental protection. The results of theoretical and experimental studies on the development of power supply systems based on thermoelectric generators in combination with photovoltaic panels, solar concentrators and heat pipes are also presented, allowing us to conclude that the creation of solar thermoelectric generators is relevant. The authors have developed a design and presented a description of the power supply installation operation with a solar thermoelectric generator and heat pipes transmitting thermal energy from a solar concentrator through a solid-state thermal storage to a thermoelectric generator. Expressions are given for calculating the main thermal characteristics of the elements of the proposed installation with a solar thermoelectric generator (solar concentrator and solid-state thermal storage), as well as the efficiency factor and output electric power of the thermoelectric generator.

“…In order to provide standard microclimate parameters for cattle management premises, an integrated energy-saving heat supply system was designed comprising electric thermal storage (ETS) units and a ceiling fan [15]. The results of the simulations and experimental studies of the heat storage cells and the thermal state of the newly-developed ETS unit in operation modes of charging and heat emission of ETS unit were reported [16,17]. An energy-saving air heating system was developed, featuring thermal energy recuperation of the exhaust air as well as ozonizing and deep recirculation [18].…”

Recommendations on the selection of air curtains and the calculation of their parameters for livestock premises in cattle management farms are made. The air curtain functioning principle is analyzed from the air jet theory point of view. The block diagram and modular design of air curtains with a variable air jet direction vector and with controlled slit width are designed. Laboratory tests of the newly designed air curtain structure are performed in accordance with the microclimate requirements for the cattle management farm premises. Based on the experimental results, the major air curtain parameters are calculated for the range from 10° to 60° of angle α between the direction of the air jet outward from the air curtain slit and aperture plane, and for the air curtain slit width b0 in the range from 0.05 m to 0.15 m with the account of the wind speed Vw variations. Calculated values for amounts of energy that have to be consumed to ensure the required air jet velocity, in the output from the air curtain, and those for the quantity of thermal energy required to heat the air supplied to the air curtain, depending on the angle α and on the slit width b0, can be helpful for selecting the power capacity of both the air curtain fan and electric heater. A block diagram of the air curtain control for cattle management farm premises is designed, enabling automatic control of the airflow rate, the angle of the air jet output from the air curtain slit, and the temperature of the heated air supplied to the air curtain, considering particular climate conditions. According to the preliminary estimate, applications of the newly designed air curtain will make it possible to reduce the energy consumed to maintain the required microclimate conditions in cattle management premises by 10% to 15% in the cold period.
