Heating performance of a heat pump system for electric buses was studied experimentally. In order to know heating performance characteristics of a heat pump, it was test under various operating conditions such as electric compressor speed and exterior temperature. Although heating capacity improves as electric compressor speed increase, COP for heating does not improves. This indicates that size of exterior heat exchanger restrict the amount of heat absorption, which inhibited the system COP for heating.
