Assignee: JOHNSON CONTROLS TYCO IP HOLDINGS LLP
Field: Thermal processes and apparatus (Mechanical engineering)
Classification: CPC F  Y | IPC F

Claim 16:
17. A multiple-circuit heating and cooling system, comprising:
a first row split heat exchanger, comprising:
a first heat exchange coil of a first refrigeration circuit; and
a second heat exchange coil of a second refrigeration circuit, wherein the first heat exchange coil is arranged entirely downstream of the second heat exchange coil relative to a first air flow directed across the first row split heat exchanger to enable the first air flow to pass sequentially through second heat exchange coil and the first heat exchange coil in series; and

a second row split heat exchanger fluidly coupled to the first row split heat exchanger, comprising:
a third heat exchange coil of the first refrigeration circuit; and
a fourth heat exchange coil of the second refrigeration circuit, wherein the fourth heat exchange coil is arranged entirely downstream of the third heat exchange coil relative to a second air flow directed across the second row split heat exchanger to enable the second air flow to pass sequentially through thorough the third heat exchange coil and the fourth heat exchange coil in series, wherein the multiple-circuit heating and cooling system is configured to discharge the second air flow toward a conditioned space to cool the conditioned space in a cooling mode.
