The present application relates to the technical field of air conditioning, and discloses a heat exchanger, comprising: a heat exchanger main body, which has at least one refrigerant inlet and outlet and multiple heat exchange branches; Wherein the second liquid separator is arranged vertically or obliquely, so that the liquid separation port is upward and the confluence pipe mouth is downward, or the liquid separation port is arranged obliquely upward and the confluence pipe mouth is inclined downward; and the heat exchanger is used as In the case of a condenser, at least one liquid inlet and at least one liquid outlet in the liquid separation port; a first one-way valve, the flow direction of which is restricted to conduct when the heat exchanger is used as an evaporator, and when the heat exchanger is used as an evaporator. In the case where the heater is used as a condenser, the second liquid separator is blocked, and the second liquid separator is combined and stored. The heat exchanger provided by the embodiment of the present disclosure can store part of the refrigerant by using a liquid separator, and the liquid separator is placed vertically or obliquely in a manner that the liquid separator is upward and the confluence pipe is downward. The present application also discloses a refrigeration cycle system and an air conditioner. |
