Ceiling mounted evaporator blower with swing up hinged installation
An evaporator blower for air conditioning system that can be installed into a ceiling between existing joists. The system has a chassis dimensioned to fit between the pair of joists forms an air flow pathway through which air may be cooled by an evaporator housed in the chassis. A mounting flange is pivotally coupled to the chassis and has an opening through which the chassis can pivot between a first position below the mounting flange, and thus the ceiling, to a second position above the flange, so that the chassis is above the ceiling and between the pair of joists. A diffuser is attached to the mounting flange and provides supply and return air grilles that are in fluid communication with the air flow pathway of the chassis.
1. An air conditioning system, comprising:
a chassis dimensioned to fit between a pair of joists and defining an air flow pathway through which air may be cooled by an evaporator housed in the chassis;
a mounting flange pivotally coupled to the chassis so that the chassis can pivot between a first position below the mounting flange to a second position above the flange; and
a diffuser attached to the mounting flange and in fluid communication with the air flow pathway of the chassis.
2. The system of claim 1 , wherein the mounting flange includes a central opening through which the chassis can pivot between the first position and the second position.
3. The system of claim 2 , wherein the chassis including a supply air section, a condenser, a fan assembly, and a return air section positioned in the air flow pathway.
4. The system of claim 3 , wherein the diffuser includes a return air grille in communication with the return air section of the chassis and a supply air grille in communication with the supply air section of the chassis.
5. The system of claim 4 , wherein the mounting flange includes a planar portion extending from the central opening.
6. The system of claim 5 , wherein the planar portion of the mounting flange is dimensioned to be secured to the pair of joists.
7. The system of claim 6 , wherein the chassis is pivotally coupled to the mounting flange by a first hinge positioned at a first end of the mounting flange.
8. The system of claim 7 , wherein the chassis includes a series of brackets for coupling to the mounting flange when the chassis is in the second position.
9. The system of claim 8 , wherein the diffuser is pivotally coupled to the mounting flange by a second hinge positioned at the first end of the mounting flange for movement between an open position and a closed position.
10. The system of claim 9 , wherein the diffuser includes at least one locking tab positioned at an opposite end from the second hinge for coupling to the mounting flange when the diffuser is in the closed position.
11. The system of claim 10 , wherein the central opening of the mounting flange is rectangular.
12. The system of claim 11 , wherein the mounting flange includes a series of walls extending from at least three sides of the central opening and perpendicularly to the planar portion.
13. The system of claim 12 , wherein the planar portion of the mounting flange includes a series of apertures positioned to allow the mounting flange to be coupled to the pair of joists if the pair of joists are either twelve of sixteen inches apart from each other.
