Thermodynamic analysis of the air handling unit with heat pump

Abstract

The air handling unit with heat recovery and air source heat pump is analyzed in this article. The main purpose of work is to determine operating parameters, thermal and thermodynamic efficiencies of this system. The calculations were done using energy and exergy analysis methods. Sensitivity analysis to know how the efficiency of heat recovery exchanger as well as the overheating of refrigerant in evaporator influences the efficiency of all system was done. The work finds that the values of COP are ranging from 1,29 to 2,06, exergy efficiency factor from 28,15% to 62,55%.
