Abstract

A method for sealing an economizer perimeter gap to reduce an uncontrolled excess outdoor airflow by applying a sealing material over or into the economizer perimeter gap between the economizer frame and a Heating, Ventilating, Air Conditioning (HVAC) system cabinet comprising: locating the economizer perimeter gap between the economizer frame and the HVAC system cabinet and applying a sealing material over or into the economizer perimeter gap. The sealing material is selected from the group consisting of: an adhesive tape sealant, an adhesive sealant, a mastic sealant, a caulking material, and a weatherstripping. The method comprises: disconnecting an electrical power to the HVAC system, removing an economizer hood, locating and cleaning the metal services on both sides of the gap between the economizer frame and the HVAC cabinet, applying the sealing material over or into the gap, reinstalling the economizer hood, and reconnecting the electrical power to the HVAC system.

Claims (25)

1. A method for sealing an economizer perimeter gap, the method comprising:

locating the economizer perimeter gap between an economizer frame and surfaces inside a Heating, Ventilating, Air Conditioning (HVAC) system cabinet behind or under an economizer hood; and

applying a sealing material over or into the economizer perimeter gap between the economizer frame and surfaces inside the HVAC system cabinet behind or under the economizer hood to improve energy efficiency.

2. The method of claim 1 , wherein the sealing material is selected from the group consisting of: an adhesive tape sealant, an adhesive sealant, a mastic sealant, a caulking, and a weatherstripping.

3. The method of claim 1 , further including:

disconnecting an electrical power service connection to the HVAC system;

removing the economizer hood from the economizer of the HVAC system prior to locating the economizer perimeter gap;

reinstalling the economizer hood to the economizer of the HVAC system, and

reconnecting the electrical power service to the HVAC system after applying the sealing material over or into the economizer perimeter gap between the economizer frame and the HVAC system cabinet.

4. The method of claim 1 , wherein applying a sealing tape comprises applying an adhesive tape sealant over or into the economizer perimeter gap between the economizer frame and surfaces inside the HVAC system cabinet behind or under the economizer hood.

5. The method of claim 1 , further including:

removing the economizer hood from the HVAC system cabinet prior to locating the economizer perimeter gap; and

reinstalling the economizer hood to the HVAC system cabinet after the applying the sealing material over or into the economizer perimeter gap between the economizer frame and the HVAC system cabinet.

6. A method for sealing an economizer perimeter gap, the method comprising:

sealing the economizer perimeter gap between an economizer frame and surfaces behind or under an economizer hood of a Heating, Ventilating, Air Conditioning (HVAC) system cabinet to reduce an uncontrolled excess outdoor airflow through the economizer perimeter gap, the sealing comprising:

applying a sealing material over or into the economizer perimeter gap between the economizer frame and surfaces behind or under the economizer hood of the HVAC system cabinet, and wherein the sealing material is selected from the group consisting of: an adhesive tape sealant, an adhesive sealant, a mastic sealant, a caulking, and a weatherstripping.

7. The method of claim 6 , further including:

removing the economizer hood from the HVAC system cabinet prior to locating the economizer perimeter gap; and

reinstalling the economizer hood to the HVAC system cabinet after the applying the sealing material over or into the economizer perimeter gap.

8. A method of sealing an economizer perimeter gap of an economizer, the method comprising:

sealing the economizer perimeter gap between an economizer frame and surfaces behind or under an economizer hood of a Heating, Ventilating, Air Conditioning (HVAC) system cabinet wherein the surfaces behind or under the economizer hood are spaced apart from the economizer hood to reduce an uncontrolled excess outdoor airflow through the economizer perimeter gap, the sealing comprising:

applying a sealing material over or into the economizer perimeter gap, and wherein the sealing material is selected from the group consisting of: an adhesive tape sealant, an adhesive sealant, a mastic sealant, a caulking, and a weatherstripping.

9. The method of claim 8 , further including:

removing the economizer hood from the HVAC system cabinet prior to locating the economizer perimeter gap; and

reinstalling the economizer hood to the HVAC system cabinet after the applying the sealing material over or into the economizer perimeter gap.
