Abstract
A refrigeration cycle device includes a flow channel coupling member which constitutes at least one of a branching portion and a joining portion of a third refrigerant passage and a branching portion and a joining portion of a bypass passage. One of three refrigerant ports of the flow channel coupling member is directly connected to one of two refrigerant ports of a first switching device or a second switching device, and a sealing mechanism preventing a refrigerant leakage is provided in a connecting portion between the refrigerant port of the flow channel coupling member and the refrigerant port of the first switching device or the second switching device. The flow channel coupling member is fixed to one of the switching devices at a position different from a position of the sealing mechanism.
