Abstract

A rooftop cooling and/or heating unit may include, but is not limited to, a supply fan and a heating and/or coiling device. The cooling device is preferably one or more chilled water coils suitably mounted within the unit in-line with fresh air delivered via an air intake hood and/or return air supplied from the return air duct. The unit further includes one or more fluid circulation pumps connected in-line with the one or more chilled water coils. Embodiments of the rooftop cooling and/or heating units may further include one or more of the following: pump compartment, controls compartment, power compartment, space for optional features, varying air filter options, mixed air dampers, optional exhaust/relief features, etc. The unit may receive part or all of its power requirements from an associated solar power generator.

Claims

1. A rooftop modular fan coil unit, comprising:

a cabinet defining an interior cavity, an air intake, an air return inlet, and an air supply outlet, wherein the air intake, the air return inlet, and the air supply outlet are disposed in communication with the cavity;

a cooling unit mounted within the cabinet;

supply and return piping fluidly connected to the cooling unit;

a cooling unit connector assembly mounted on the cabinet and fluidly connected to the supply and return piping;

a monoflow pump fluidly connected between the cooling unit and the cooling unit connector assembly; and

an air supply fan for moving air across the cooling unit and out through the air supply outlet.

2. The unit of claim 1, further comprising a power connector mounted on the cabinet.

3. The unit of claim 2, wherein the power connector is electrically connected to the pump and the fan.

4. The unit of claim 1, further comprising space within the cabinet for housing at least one device selected from a group of devices consisting of batteries, power components, and control components.

5. The unit of claim 1, further comprising a heating unit mounted within the cabinet.

6. The unit of claim 5, wherein the heating unit is selecting from a group consisting of a hot water coil, a heat reclaim coil, and an electric heating coil.

7. The unit of claim 5, further comprising supply and return piping fluidly connected to the heating unit and a heating device connector assembly mounted on the cabinet.

8. The unit of claim 1, further comprising at least one device selected from a group of devices consisting of dampers, reclaim devices, UV purification lights, and filters.

9. The unit of claim 1, further comprising a control communicatively connected to the pump and/or the fan.

10. The unit of claim 1, further comprising a solar power connector mounted on the cabinet for connecting to an associated solar power generator.

11. A rooftop modular fan coil unit, comprising:

a cabinet defining an interior cavity, an air intake, an air return inlet, and an air supply outlet, wherein the air intake, the air return inlet, and the air supply outlet being disposed in communication with the cavity;

a cooling unit mounted within the cabinet;

supply and return piping fluidly connected to the cooling unit;

a cooling unit connector assembly mounted on the cabinet and fluidly connected to the supply and return piping;

a monoflow pump fluidly connected between the cooling unit and the cooling unit connector assembly;

an air supply fan for moving air across the cooling unit and out through the air supply outlet;

an electrical assembly electrically connecting a motor of the air supply fan and the pump to an electrical connector mounted on the cabinet; and

a solar power unit positioned external the cabinet and electrically connected to the electrical connector.
