Abstract: The exergy losses analysis of a heat pump air-conditioning system under space cooling and heating mode was carried out by the surrounding analysis method in order to observe the distribution of the exergy losses of each component, and the direction of optimizing the heat pump air conditioning system from the perspective of reducing the irreversible losses was discussed. The exergy losses analysis of the heat pump air conditioning system is also made in comparison with a PTC heating heater system, the results show that the performance of the heat pump air conditioning system is significantly better than that of the PTC heater. The exergy losses of the PTC heater are about four times of that of the heat pump air conditioning system. Keywords:
