Embedded heat exchanger for heating, ventilatiion, and air conditioning (hvac) systems and methods

A zone-control unit for use in a heating, ventilation, and air conditioning (HVAC) system, the zone-control unit comprising:

• a casing;
• a coil disposed at least partially within the casing;
• an inlet piping assembly coupled with the coil for supplying fluid to the coil;
• an outlet piping assembly coupled with the coil for receiving fluid from the coil;
• a bracket that maintains the casing, the inlet piping assembly, and the outlet piping assembly in positional relationship;
• and
• an ancillary component coupled with the coil, the bracket, or the casing.

A method of manufacturing a plurality of portable piping structures, comprising:

• providing a first heat exchange coil having a first dimension;
• providing a second heat exchange coil having a second dimension;
• coupling a first inlet piping assembly and a first outlet piping assembly with the first heat exchange coil to provide a first portable piping structure of the plurality of portable piping structures;
• coupling a second inlet piping assembly and a second outlet piping assembly with the second heat exchange coil to provide a second portable piping structure of the plurality of portable piping structures;
• coupling a first bracket with the first inlet piping assembly and the first outlet piping assembly, wherein the first bracket provides a known spacing distance between a central longitudinal axis defined by the first inlet piping assembly and a central longitudinal axis defined by the first outlet piping assembly;
• and
• coupling a second bracket with the second inlet piping assembly and the second outlet piping assembly, wherein the second bracket provides the known spacing distance between a central longitudinal axis defined by the second inlet piping assembly and a central longitudinal axis defined by the second outlet piping assembly.
