Abstract: A heat exchanger includes a liquid reservoir configured to separate a gas-liquid two-phase refrigerant flowing out of an upstream heat exchanging portion into a gas-phase refrigerant and a liquid-phase refrigerant and store the liquid-phase refrigerant, and a first adjustment portion and a second adjustment portion configured to adjust an outflow state and an outflow destination of the refrigerant flowing out of a downstream heat exchanging portion or the liquid reservoir. The liquid reservoir includes a liquid reserving portion configured to store the liquid-phase refrigerant, and a gas reserving portion configured to store the gas-phase refrigerant. The first adjustment portion and the second adjustment portion face the liquid reserving portion across the gas reserving portion.

Abstract: 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.
