Study of the efficiency of heating, ventilation and air conditioning units for electric trucks and buses in Russian climatic conditions

Abstract

In this paper, a study was made of the thermodynamic efficiency of the cycles of heating, ventilation and air conditioning (HVAC) installations, depending on the seasonal modes of operation of electric vehicles, both in the heating mode in winter and in the air conditioning mode in summer, using freons R134A, R-290, R404a, R407C, R410a, R502, R507a, R-744, R1234YF. Keywords: air conditioning, heating, vapor compression refrigeration, HVAC, efficiency, freon, electric heavy duty vehicle, electric bus
