Abstract: A refrigerant flow path switch arranged between an outdoor device and each of multiple indoor devices controls a refrigerant flow and is provided with a housing; a refrigerant flow path switching circuit having multiple refrigerant flow path switching circuits, wherein each refrigerant flow path switching circuit includes a high/low pressure gas pipe, a low pressure gas pipe, a high/low pressure electric valve provided at the high/low pressure gas pipe, and a low pressure electric valve provided at the low pressure gas pipe. A liquid pipe assembly is arranged in the housing and has multiple liquid pipes connected to the multiple indoor devices. A first divider plate is provided between adjacent ones of the refrigerant flow path switching circuits and divides an internal space of the housing such that a space divided by the first divider plate is in a substantially cubic shape, which is filled with a foaming agent.
