Heat exchanger for an hvac&r system

A heating, ventilation, air conditioning, and refrigeration (HVAC&R) system, comprising:

• a first heat exchanger, comprising:
• a first shell configured to receive a working fluid of a working fluid circuit;
• a first plurality of tubes disposed within the first shell and extending along a longitudinal axis;
• a first tube sheet attached to a first end of the first shell and configured to support the first plurality of tubes within the first shell;
• and
• a second tube sheet attached to a second end of the first shell, opposite the first end, and configured to support the first plurality of tubes within the first shell;
• and
• a second heat exchanger, comprising:
• a second shell configured to receive the working fluid of the working fluid circuit;
• a second plurality of tubes disposed within the second shell and extending along the longitudinal axis;
• a third tube sheet attached to a third end of the second shell and configured to support the second plurality of tubes within the second shell;
• and
• a fourth tube sheet attached to a fourth end of the second shell, opposite the third end, and configured to support the second plurality of tubes within the second shell,
• wherein the first tube sheet and the third tube sheet are aligned with one another in a lateral direction extending crosswise to the longitudinal axis, and the second tube sheet and the fourth tube sheet are offset from one another along the longitudinal axis.

A heating, ventilation, air conditioning, and refrigeration (HVAC&R) system, comprising:

• a first heat exchanger comprising a first shell, a first plurality of tubes disposed within the first shell, and a first tube sheet coupled to the first shell and configured to support the first plurality of tubes within the first shell, wherein the first shell and the first plurality of tubes extend along a longitudinal axis;
• and
• a second heat exchanger comprising a second shell, a second plurality of tubes disposed within the second shell, and a second tube sheet coupled to the second shell and configured to support the second plurality of tubes within the second shell, wherein the second shell and the second plurality of tubes extend along the longitudinal axis,
• wherein the first tube sheet and the second tube sheet are aligned with one another in a lateral direction extending crosswise to the longitudinal axis, the first plurality of tubes comprises a first length along the longitudinal axis, the second plurality of tubes comprises a second length along the longitudinal axis, and the first length is less than the second length.
