Development of energy-saving technology for maintaining the functioning of heat pump power supply

Abstract: Розроблено iнтегровану систему пiдтримки функцiонування теплонасосного енергопостачання на основi прогнозування змiни температури мiсцевої води. Змiна витрати пари холодагента, числа обертiв електродвигуна компресора вiдбувається при вимiрюваннi температури холодагента на виходi iз конденсатора, тиску випаровування, тиску конденсацiї та частоти напруги. Виконано комплексне математичне моделювання теплонасосної системи, що базується на iнтегрованiй системi пiдтримки розряду грунту на рiвнi 10-8°С. Визначено вит… Show more

“…-to develop the block diagram and to perform logical modeling regarding obtaining the integrated Smart Grid system of maintenance of the cogeneration system operation at the decision making level; -to ensure harmonization of production of electric power and heat based on the prediction of a change in power factor of the cogeneration system, the temperature of local water in the engine cooling circuit at a consumption change. Based on the methodological and mathematical substantiation of the architecture of technological systems [1], energy-saving technologies of biogas production with the use of heat-pumping energy supply [3,4], the architecture of the Smart cogeneration biogas system was proposed (Fig. 1).…”

“…The use of hybrid solar collectors for low-grade energy sources based on the lower section of the storage tank requires coordination of the functioning of dynamic systems: a low-grade energy source -an evaporator, an evaporator-compressor, a compressor-condenser based on predicting changes in the temperature of local water. Thus, in [20], an integrated system for supporting the functioning of heat pump power supply was developed based on predicting changes in the temperature of local water. This system is based on measuring the temperature of the refrigerant at the outlet of the condenser in relation to the measured evaporation pressure, which are part of the analytical definitions of the refrigerant flow rate and the number of revolutions of the compressor motor.…”
