Suction line heat exchanger

A refrigerant system, comprising:

• a compressor fluidically coupled between a suction line heat exchanger and a first heat exchanger;
• the first heat exchanger fluidically coupled between the compressor and the suction line heat exchanger;
• a second heat exchanger fluidically coupled with the suction line heat exchanger;
• the suction line heat exchanger, wherein the suction line heat exchanger includes:
• an outer chamber including a first refrigerant channel,
• an inner chamber including a second refrigerant channel distinct from the first refrigerant channel, wherein the inner chamber is disposed within the outer chamber,
• a first set of ports fluidically coupling the first heat exchanger with the second heat exchanger via the second refrigerant channel, and
• a second set of ports fluidically coupling the second heat exchanger with the compressor via the first refrigerant channel;
• and
• wherein:
• the inner chamber receives a first portion of refrigerant from the first heat exchanger and guides the first portion of refrigerant toward the second heat exchanger,
• the outer chamber receives a second portion of refrigerant from the second heat exchanger and guides the second portion of refrigerant toward the compressor, and
• the second portion of refrigerant substantially fills the outer chamber and surrounds the inner chamber such that heat transfers between the first portion of refrigerant and the second portion of refrigerant.

A method of manufacturing a suction line heat exchanger, comprising:

• providing an outer chamber including a first refrigerant channel;
• providing an inner chamber including a second refrigerant channel distinct from the first refrigerant channel;
• disposing the inner chamber within the outer chamber such that the inner chamber is exposed to a refrigerant receive within the outer chamber;
• providing a first set of ports for receiving and providing the refrigerant via the second refrigerant channel;
• and
• providing a second set of ports for receiving and providing the refrigerant via the first refrigerant channel.
