A heat pump system includes a compressor that compresses and discharges a refrigerant, a decompressor that decompresses the refrigerant, an outdoor unit that exchanges heat between the refrigerant and an outside air, an evaporator that evaporates the refrigerant, a condenser that condenses the refrigerant, an internal heat exchanger, an accumulator that separates the refrigerant into a gas refrigerant and a liquid refrigerant, and a flow pathway changing portion. The internal heat exchanger includes a high-pressure passage through which a high-pressure refrigerant flows, and a low-pressure passage through which a low-pressure refrigerant flows, the internal heat exchanger exchanging heat between the refrigerant flowing through the high-pressure passage and the refrigerant flowing through the low-pressure passage. The flow pathway changing portion that switches between a cooling pathway and a heating pathway. According to this heat pump system, a cooling capacity and a heating capacity can be improved.
