Abstract
A refrigerant flow path module includes: a first pipe portion having a cylindrical flow path and connected to a discharge pipe through which a refrigerant discharged from a compressor of a refrigerant circuit flows; and a second pipe portion having a cylindrical flow path and connected to a suction pipe through which a refrigerant to be sucked into the compressor flows. The first pipe portion and the second pipe portion are integrally formed. An end of the first pipe portion is connected to an end of the discharge pipe. An end of the second pipe portion is connected to an end of the suction pipe.
Claims13
A refrigerant flow path module comprising:
- a first pipe portion having a cylindrical flow path and connected to a discharge pipe through which a refrigerant discharged from a compressor of a refrigerant circuit flows;
- and
- a second pipe portion having a cylindrical flow path and connected to a suction pipe through which a refrigerant to be sucked into the compressor flows, wherein
- the refrigerant circuit comprises:
- a first heat exchanger;
- a second heat exchanger;
- and
- a flow path switching valve that switches a refrigerant flow path from the compressor to the first heat exchanger and a refrigerant flow path from the compressor to the second heat exchanger,
- the first pipe portion and the second pipe portion are integrally formed separately from the flow path switching valve,
- a first end of the first pipe portion is connected to an end of the discharge pipe,
- a second end of the first pipe portion is connected to the flow path switching valve,
- a first end of the second pipe portion is connected to an end of the suction pipe, and
- a second end of the second pipe portion is connected to the flow path switching valve.
A refrigerant flow path module comprising:
- a first pipe portion having a cylindrical flow path and connected to a discharge pipe through which a refrigerant discharged from a compressor of a refrigerant circuit flows,
- wherein
- the refrigerant circuit comprises:
- the compressor;
- a first heat exchanger;

- and
- a flow path switching valve that switches a refrigerant flow path from the compressor to the first heat exchanger and a refrigerant flow path from the compressor to the second heat exchanger;
- a second pipe portion having a cylindrical flow path and connected to a suction pipe through which a refrigerant to be sucked into the compressor flows;
- a third pipe portion having a cylindrical flow path, connected to the flow path switching valve, and through which a refrigerant flows from the flow path switching valve to the first heat exchanger;
- a fourth pipe portion having a cylindrical flow path, connected to the flow path switching valve, and through which a refrigerant flows from the flow path switching valve to the second heat exchanger;
- and
- the flow path switching valve of the refrigerant circuit, wherein
- the flow path switching valve comprises a rotary valve body that switches and that connects the first pipe portion to either the third pipe portion or the fourth pipe portion,
- the first pipe portion, the second pipe portion, the third pipe portion, and the fourth pipe portion extend in a same direction from the flow path switching valve, and
- at least two of the first pipe portion, the second pipe portion, the third pipe portion, and the fourth pipe portion are integrally formed at portions of the at least two of the first pipe portion, the second pipe portion, the third pipe portion, and the fourth pipe portion protruding from the flow path switching valve.
