Method of controlling heat pump system of electric vehicle

Abstract

A method of controlling a heat pump system of an electric vehicle, whereby power consumed for air conditioning is reduced during driving in a low load state in a heating mode, includes determining whether a heat dissipation amount insufficient condition of an indoor condenser is satisfied in the heat pump system of the electric vehicle. When it is determined that the heat dissipation amount insufficient condition of the indoor condenser is satisfied, measuring current revolutions per minute (rpm) of a compressor. It is determined whether the measured rpm of the compressor is greater than a minimum rpm limit of the compressor. When it is determined that the measured rpm of the compressor is greater than the minimum rpm limit of the compressor, the rpm of the compressor is reduced.
