Abstract

An energy recovery ventilator unit. The unit comprises a cabinet housing a primary intake zone, a supply zone, a return zone, an exhaust zone and an enthalpy-exchange zone. The primary intake zone and the exhaust zone are both on one side of the enthalpy exchange zone. The supply zone and the return zone are both on an opposite side of the enthalpy exchange zone. The unit also comprises first and second blowers. The first blower is located in the primary intake zone and configured to push outside air into the primary intake zone and straight through the enthalpy exchange zone into the supply zone. The second blower is located in the return zone and configured to push return air into the return zone and straight through the enthalpy exchange zone into the exhaust zone.

Claims

1. An energy recovery ventilator unit, comprising:

a cabinet housing a primary intake zone, a supply zone, a return zone, an exhaust zone and an enthalpy-exchange zone, wherein;

the primary intake zone and the exhaust zone are both on one side of the enthalpy exchange zone, and

the supply zone and the return zone are both on an opposite side of the enthalpy exchange zone;

a first blower located in the primary intake zone and configured to push outside air into the primary intake zone and straight through the enthalpy exchange zone into the supply zone; and

a second blower located in the return zone and configured to push return air into the return zone and straight through the enthalpy exchange zone into the exhaust zone, and wherein the cabinet includes;

an intake opening connected to the primary intake zone and an exhaust opening connected to the exhaust zone, both of the primary intake and exhaust openings being located in an end wall on one end of the cabinet,

a supply opening connected to the supply zone and a return opening connected to the return zone, both the supply and return openings being located on an opposite end wall of the cabinet,

a secondary intake opening located in a side wall of the cabinet that is different from the end wall and opposite end wall, connected to the supply zone, proximately positioned vertically above the return zone, and downstream of the first blower, the secondary intake opening configured to provide a controlled delivery of atmospheric air to the supply zone;

a first access opening providing access to the primary intake zone;

a second access opening providing access to the return zone; and

a third access opening providing access to the enthalpy-exchange zone;

wherein the first, second, and third openings are located in the side wall of the cabinet where the secondary intake opening is located.

2. The unit of claim 1, wherein the first and second blowers when blowing air cause the primary intake zone, the supply zone, the return zone, the exhaust zone and the enthalpy-exchange zone to all have a positive pressure as compared to the atmospheric pressure outside of the cabinet.

3. The unit of claim 1, wherein the primary intake zone and the exhaust zone are vertically stacked, and, the supply zone and the return zone are vertically stacked.

4. The unit of claim 1, wherein the primary intake zone is vertically stacked above the exhaust zone, and, the supply zone vertically stacked above the return zone.

5. The unit of claim 1, wherein the enthalpy-exchange zone includes an enthalpy-exchanger device configured as one or more enthalpy wheels.

6. The unit of claim 5, wherein the one or more enthalpy wheel is vertically oriented with respect to a base that the unit is located on.

7. The unit of claim 1, wherein the first and the second blowers are configured as impeller blowers.

8. The unit of claim 1, wherein the primary intake zone and the return zone each include separate mounting platforms configured to support a blower subunit thereon, and the mounting platforms are configured to slide in and out of the cabinet.

9. The unit of claim 1, where the enthalpy-exchange zone includes a mounting platform being configured to support an enthalpy-exchange device thereon, and the mounting platform is configured to slide in and out of the cabinet.

10. The unit of claim 1, wherein the secondary intake opening is covered with an air controller assembly, wherein the controller assembly is configured to control the volume of the outside air passing through the secondary intake opening.

11. The unit of claim 1, wherein the supply zone and the return zone are coupled to an air-handler unit, and the energy recovery ventilator unit and the air handler unit are both part of a space conditioning system.
