Classification: CPC F  Y | IPC F

Claim 11:
12. A multiple-circuit heating and cooling system, 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 and the second heat exchange coil are arranged in a first slab, and the first heat exchange coil is entirely downstream of the second heat exchange coil relative to a first air flow directed across the first slab; and
a third heat exchange coil of the first refrigeration circuit and a fourth heat exchange coil of the second refrigeration circuit, wherein the third heat exchange coil and the fourth heat exchange coil are arranged in a second slab, and the fourth heat exchange coil is entirely downstream of the third heat exchange coil relative to a second air flow directed across the second slab, wherein the multiple-circuit heating and cooling system is configured to discharge the second air flow toward a conditioned space to enable cooling of the conditioned space in a cooling mode and heating of the conditioned space in a heating mode.
