Electric Heating System with Thermal Storage Units and Ceiling Fans for Cattle-Breeding Farms

Abstract

A combined energy–saving heat supply system was proposed that included a combined ETS unit and a ceiling fan, and provided the normative air parameters in a livestock room, with an air temperature of −17 °C and air relative humidity (ARH) of −75%. A heat supply system of a preventive maintenance premises for calves was chosen as the subject of the study. Comparative analysis of the temperature and ARH distribution with height in the preventive maintenance premises, was carried out, with and without a ceiling fan. The study showed that, during the heating period, application of the ceiling fans helped to raise the air temperature and to reduce ARH, in the areas where young stock is located, in accordance with the normative indicators. The energy-saving effect was achieved by supplying warmer ventilation air, which accumulated in the upper zone of the premises from the ceiling fan to the locations of the animals. At the same time, there was a decrease in the consumption of electric energy for the heat supply system of up to 14%.

Power supply installation for remote rural settlements with solar thermoelectric generator

“…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].…”

Evolution of Agriculture : A Survey

“…Consumers are subject to the impacts of bio stimulants, which have an impact on their health. The organic Ugmax productionprocess dramatically increases the number of leaves, the length of the root, and the width of the root neck compared to the control variety in order to lessen the biochemical effects.In [34],author's have concluded that,Electric heating systems: Research into the heating-ventilation system used in cattle-breeding farm preventative maintenance buildings during the winter seasonhas revealed that using ceiling fans can shorten the time it takes for buildings to heat and cool. The usage of electric heating systems was reduced at the same time, which resulted in a drop in energy consumption.…”

Promotive Effect of Non-Woven Polylactide/Natural Rubber Composites on Growth and Biochemical Constituents of Purple Basil (Ocimum basilicum L.)

“…Modern agriculture needs new methods and technologies of crop production. To increase plant productivity and yields, various measures are used: digital innovations in soil cultivation, new mineral fertilizers, and non-standard methods of growing agricultural crops [12][13][14]. The application of smart functional covering polymer materials and substrates for growing crops, especially in breeding, where the most expensive and valuable seed material is used, contributes to the development of the field of effective crop production [15,16].…”
