Abstract

At agricultural facilities, the main attention is paid to the formation and maintenance of their microclimate parameters, and mechanization of storage processes. As world experience shows, it is necessary to develop and implement energy-saving systems and the use of renewable energy sources. The authors have developed energy-saving systems based on the heat pump, with upgraded electrical regulators. The developed system (patent 100873), uses thermoelectric elements and a low-potential energy source, to effectively maintain the temperature parameters of the microclimate during long-term storage of potatoes, but it requires a large amount of electricity consumption (30 to 35 kW), so the authors have developed an energy-saving system based on a heat pump (patent 123909). The temperature regime is achieved by using a thermoelectric cooler-heater and an electric heater. The humidifier allows for maintaining the necessary relative air humidity.

Background

Currently, thermoelectric heat pumps (HP) and HP on a low-potential energy source are widely used (Gorshkov, 2004). Thermoelectric HP operating on Peltier and Thomson effects have low efficiency and high cost (Ray & McMichael, 1982). However, the company TERMIONA (Moscow) developed thermoelectric elements that increase the cooling capacity and efficiency of generation by 15-30%, which will significantly increase the energy efficiency of devices (Naer & Garachuk, 1982). Currently, on the instructions of the Ministry of industry and energy of the Russian Federation a program for the development of non-traditional energy in Russia, including HP is being developed (Kalnin & Savitsky, 2000).

Therefore, the relevance of the use of low-potential energy is now objectively justified (Vasiliev & Krundyshev, 2002).

Production of HP in each country is focused, first of all, on satisfaction of requirements of the domestic market. Abroad, the active introduction of heat pumps contributes to the International Energy Agency. The European Heat Pump Association presented data on sales of heat pump equipment in 2015, while the heat pump market grew by 10% (Berzan, Robu, & Sheet, 2011).
