Climate control systems having a liquid-to-suction heat exchanger, an accumulator, and a receiver for variable liquid storage of high glide working fluids and methods for operation thereof

A climate control system that circulates a working fluid comprising a refrigerant blend having high glide, the climate control system comprising:

• the working fluid comprising a first refrigerant and a second refrigerant, wherein a difference in boiling points between the first refrigerant and the second refrigerant is greater than or equal to about 25°R at atmospheric pressure, wherein the climate control system is configured to maintain the working fluid in a sub-critical state during operation;
• an accumulator;
• a compressor that receives a vapor stream of the working fluid from the accumulator and generates a pressurized vapor stream;
• a first heat exchanger disposed downstream of the compressor that receives and cools the pressurized vapor stream to generate a multiphase or liquid condensate stream of the working fluid;
• a liquid-to-suction heat exchanger disposed downstream of the first heat exchanger and upstream of the accumulator;
• a receiver disposed downstream of the liquid-to-suction heat exchanger;
• a first expansion device disposed between the liquid-to-suction heat exchanger and the receiver that processes the multiphase or liquid condensate stream from the liquid-to-suction heat exchanger;
• a second expansion device disposed between the receiver and a second heat exchanger that processes the multiphase or liquid condensate stream to reduce pressure prior to the second heat exchanger to form a reduced-pressure multiphase stream of the working fluid;
• the second heat exchanger receives the reduced-pressure multiphase stream from the second expansion device and at least partially vaporizes the reduced-pressure multiphase stream to form a vaporized stream of the working fluid that is then directed to the liquid-to-suction heat exchanger and to the accumulator;
• and
• a fluid conduit for circulating the working fluid and establishing fluid communication between the accumulator, the compressor, the first heat exchanger, liquid-to-suction heat exchanger, the first expansion device, the receiver, the second expansion device, and the second heat exchanger through which the working fluid circulates.
