Abstract
A multiple-circuit heating and cooling system includes a first refrigeration circuit having a first condenser and a first evaporator and a second refrigeration circuit having a second condenser and a second evaporator. The first condenser and the second condenser are arranged in a first row split configuration, and the second condenser is downstream of the first condenser relative to a first air flow directed across the second condenser and the first condenser. Additionally, the first evaporator and the second evaporator are arranged in a second row split configuration, and the first evaporator is downstream of the second evaporator relative to a second air flow directed across the first evaporator and the second evaporator.
Claims20
A multiple-circuit heating and cooling system, comprising:
- a first refrigeration circuit comprising a first heat exchanger and a second heat exchanger;
- and
- a second refrigeration circuit comprising a third heat exchanger and a fourth heat exchanger, wherein:
- the first heat exchanger and the third heat exchanger are arranged in a first row split configuration, and the first heat exchanger is entirely downstream of the third heat exchanger relative to a first air flow directed across the third heat exchanger and the first heat exchanger;
- the second heat exchanger and the fourth heat exchanger are arranged in a second row split configuration, and the fourth heat exchanger is entirely downstream of the second heat exchanger relative to a second air flow directed across the second heat exchanger and the fourth heat exchanger;
- and
- 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.
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.
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.
