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.
Claims26
A multiple-circuit heating and cooling system, comprising:
- a first refrigeration circuit comprising a first condenser and a first evaporator;
- and
- a second refrigeration circuit comprising a second condenser and a second evaporator,
- wherein the first condenser and the second condenser are arranged in a first row split configuration, and the first condenser is entirely downstream of the second condenser relative to a first air flow directed across the second condenser and the first condenser,
- wherein the first evaporator and the second evaporator are arranged in a second row split configuration, and the second evaporator is entirely downstream of the first evaporator relative to a second air flow directed across the first evaporator and the second evaporator, and
- 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.
A multiple-circuit heating and cooling system, comprising:
- a first condenser coil of a first refrigeration circuit and a second condenser coil of a second refrigeration circuit, wherein the first condenser coil and the second condenser coil are arranged in a first slab, and the first condenser coil is entirely downstream of the second condenser coil relative to a first air flow directed across the first slab;
- and
- a first evaporator coil of the first refrigeration circuit and a second evaporator coil of the second refrigeration circuit, wherein the first evaporator coil and the second evaporator coil are arranged in a second slab, and the second evaporator coil is entirely downstream of the first evaporator 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.
A multiple-circuit heating and cooling system, comprising:
- a row split condenser, comprising:
- a first condenser coil of a first refrigeration circuit;
- and
- a second condenser coil of a second refrigeration circuit, wherein the first condenser coil is arranged entirely downstream of the second condenser coil relative to a first air flow directed across the row split condenser to enable the first air flow to pass sequentially through the second condenser coil and the first condenser coil in series;
- and
- a row split evaporator fluidly coupled to the row split condenser, comprising:
- a first evaporator coil of the first refrigeration circuit;
- and
- a second evaporator coil of the second refrigeration circuit, wherein the second evaporator coil is arranged entirely downstream of the first evaporator coil relative to a second air flow directed across the row split evaporator to enable the second air flow to pass sequentially through the first evaporator coil and the second evaporator 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.
