Scroll compressor with engineered shared communication port

A method of communicating working fluid at an intermediate pressure with an asymmetric scroll compressor, comprising:

• orbiting an orbiting scroll member affixed to a driveshaft from a first orbital position to a second orbital position to intermesh with a non-orbiting scroll member of the asymmetric scroll compressor, forming a plurality of compression pockets, and the orbiting scroll member and the non-orbiting scroll member each include a baseplate and a wrap extending from the baseplate;
• receiving the working fluid at a suction pressure from a suction intake disposed between the orbiting scroll member and the non-orbiting scroll member;
• enclosing the working fluid in the suction intake to obtain a first enclosed pocket of the plurality of compression pockets;
• communicating the working fluid at an intermediate pressure from a communication port that includes a communication port outlet having a comet shape, wherein the comet shape has a head connected to a tail, the communication port disposed on a baseplate of the non-orbiting scroll such that:
• in the first orbital position, communicating with the first enclosed pocket of the plurality of compression pockets via the communication port outlet, and
• in the second orbital position, communicating with a second enclosed pocket of the plurality of compression pockets via the communication port outlet;
• and
• discharging the working fluid at a discharge pressure through a discharge outlet,
• wherein the orbiting scroll member has an intermediate orbital position between the first orbital position and the second orbital position such that:
• in the intermediate orbital position, the communication port communicates with both the first enclosed pocket and the second enclosed pocket, wherein the communication port outlet spans across the wrap of the orbiting scroll member to extend onto both the first enclosed pocket and the second enclosed pocket, wherein
• a first portion of the head of the comet shape is located on the first enclosed pocket, the first portion of the head of the comet shape communicates with a length of the comet shape, and the length contains a portion of the tail and a second portion of the head of the comet shape that is different from the first portion of the head of the comet shape, and
• the second portion of the head and the portion of the tail are collectively located on the second enclosed pocket.

A refrigerant circuit, comprising:

• an asymmetric scroll compressor, an expander, a condenser, and an evaporator fluidly connected, wherein the asymmetric scroll compressor includes:
• a compressor housing;
• an orbiting scroll member and a non-orbiting scroll member disposed within the compressor housing, the orbiting scroll member and the non-orbiting scroll member each include a baseplate and a wrap extending from the baseplate, the orbiting scroll member and the non-orbiting scroll member intermeshed to form a plurality of compression pockets;
• a driveshaft affixed to the orbiting scroll member configured to orbit the orbiting scroll member from a first orbital position to a second orbital position;
• a communication port including a communication port outlet having a comet shape, wherein the comet shape has a head connected to a tail, the communication port disposed on the baseplate of the non-orbiting scroll such that:
• in the first orbital position, the communication port outlet communicates with a first enclosed pocket of the plurality of compression pockets, and
• in the second orbital position, the communication port outlet communicates with a second enclosed pocket of the plurality of compression pockets,
• wherein the orbiting scroll member has an intermediate orbital position between the first orbital position and the second orbital position such that:
• in the intermediate orbital position, the communication port communicates with both the first enclosed pocket and the second enclosed pocket, wherein the communication port outlet spans across the wrap of the orbiting scroll member to extend onto both the first enclosed pocket and the second enclosed pocket, wherein
• a first portion of the head of the comet shape is located on the first enclosed pocket, the first portion of the head of the comet shape communicates with a length of the comet shape, and the length contains a portion of the tail and a second portion of the head of the comet shape that is different from the first portion of the head of the comet shape, and
• the second portion of the head and the portion of the tail are collectively located on the second enclosed pocket.
