THE USE OF THERMOELECTRIC HEAT PUMP IN TECHNOLOGICAL PROCESSES ON A CATTLE FARM
This paper discusses the issue of improving heat supply and ventilation systems aimed at reducing the energy consumption spent on creating and maintaining the required microclimate in farm buildings. The scheme of an innovative energy-saving installation for heating water for animal watering and air supply for a thermal curtain using thermoelectric heat pumps (Peltier thermoelectric modules) was developed. Air-curtains are the equipment that allows maintaining an optimal microclimate in rooms where the doorways and gates are open to the air outside. It has been found that the use of air-thermal curtains is an effective way to reduce energy consumption for maintaining the microclimate. For the efficient operation of the thermoelectric air heating unit in the air-heat curtain, the cooling circuit absorbs thermal energy from the removed ventilation air. The obtained energy is transferred via the “electronic wind” to the hot circuit of the thermoelectric module and acts as a heat pump transferring thermal energy from the ventilation air to water for animals to drink, i.e. to another technological substance.
