Investigation of Air Exergy from Condenser of Air Split-Conditioner Heat Pump and Its Exergetic Efficiency Depending on Outside Air Temperature

Rising prices for fuel and energy resources make the problem of using alternative energy sources and energy saving relevant not only for the economy of Ukraine, but also for the world economy. One of the ways to reduce energy consumption is the use of air split-conditioner heat pumps in building heating systems, which are using up to 1 kW of electricity from the grid to transport up to 5 kW of heat energy from the outdoor air to the indoor air. The energy perfection of air split-conditioner heat pumps can best be established only on the basis of the analysis of their exergy efficiency.

The dependence of exergy losses in elements of air split-conditioners refrigerating machines from adiabatic and electromechanical output-input ratio for compressor

The elaborating method of the exergetic analysis of air split-conditioners one-step Freon refrigeration machines was used in this article. The dependence of exergy losses for compressor, condenser, throttle and evaporator of air split-conditioner of firm “Sanyo” with cooling capacity 2020 W from adiabatic and electromechanical output-input ratio for compressor was defined.
