Description

SHROUD AND CONDENSER MOUNTING ARRANGEMENT FOR AN AIR CONDITIONING UNIT
BACKGROUND OF THE INVENTION This application relates to a condenser and shroud mounting arrangement for an air conditioning unit. More particularly, the application relates to an arrangement for supporting a tube sheet end of the condenser relative to the shroud and structural members of the air conditioning unit.
Room air conditioning units include a compressor that circulates refrigerant from an evaporator to produce cooled air for the room. The refrigerant is circulated to a condenser, which is typically rearward mounted and exposed to the outside environment. The condenser receives air from a fan to reject heat from the condenser before returning to the compressor.
One example air conditioning unit is a window mounted unit requiring a compact design. L-shape or U-shape condensers have been used in window air conditioning units to reject a greater amount of heat in a compact package. The condenser must be securely retained within a housing of the air conditioning unit. Typically, a shroud is arranged interiorly of the condenser for providing a seal between the fan and the condenser. Ends of the condenser are typically supported by a tube sheet through which condenser coils extend. Each tube sheet typically includes several apertures on one side, which are used to secure the tube sheets to opposing ends of the shroud. One example shroud includes a rather large side wall that obstructs the exterior of the short leg of an L-shape condenser. The side wall prevents the fan from blowing air across the short leg, thereby reducing the amount of heat the short leg is able to reject. Moreover, the large shroud side wall unnecessarily adds material, weight and cost to the shroud.
What is needed is an improved mounting arrangement between the condenser and shroud, which does not reduce the efficiency of the shroud while adequately supporting the condenser.
SUMMARY OF THE INVENTION An air conditioning unit is provided that includes a condenser having an elongated portion and a bent portion. In one example, the condenser is a L-shape or U-shape. The bent portion is supported by a tube sheet providing first and second wall portions. The first wall portion is secured to a condenser shroud, and a second wall portion is secured to a housing.
In one example, condenser coils extend from the tube sheet. The condenser coils are unobstructed by the shroud. In one example, the shroud includes a lateral wall having an orifice surrounding a fan. A side wall extends from the lateral wall and includes a flange. The flange is secured to the first wall portion by fasteners, in one example. In one example, the second wall portion is spaced from the first wall portion and secured to a base pan of the housing at one end and a top cover at another end.
These and other features of the present invention can be best understood from the following specification and drawings, the following of which is a brief description. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An air conditioning unit 10 is shown in Figure 1. The unit 10 has a housing that includes a base pan 12 and wrapper assembly 14. The base pan 12 supports a compressor 16 that pumps refrigerant to a condenser 18. An expansion device (not shown) is arranged in a known manner, for example, upstream from the condenser 18. The expanded refrigerant flows to an evaporator 20 before returning to the compressor 16. A motor 24 blows air through the evaporator 20 using a blower 26 to provide cooled air through a front grille 22, which is exposed to an interior room for example. The blower 26 recirculates room air through a partition 28 to further cool the recirculated air.
Refrigerant from the evaporator 20 is exposed to the outside environment in one example. A fan 30 is driven by the motor 24 to blow air across the condenser 18 to reject heat from the refrigerant to the outside environment. A condenser orifice or shroud 32 provides a seal between the condenser 18 and the fan 30. In one example, the housing all includes a top cover 34 arranged between the shroud 32 and condenser 18 to provide an enclosure about the fan 30. A controller 36 communicates with the compressor
16 and motor 24 in a known manner to provide a desired conditioned air to the room.
In one example arrangement shown in Figures 2 and 3, the condenser 18 includes first and second condenser rows 38, 40 respectively having first and second condenser coils 42, 44 to which fins are attached. The condenser 18 includes an unbent state (Figure 2) and a bent state (Figure 3). In one example, the bent state may provide an L-shape or U-shape arrangement.
Ends of the first and second condenser rows 38, 40 are supported by a tube sheet 46 in the unbent state. The tube sheet 46 includes a surface 51 having openings
48 and elongated slots 49. The first condenser coils 42 extend through and are securely retained by openings 48 in the tube sheet 46. The tube sheet 46 also includes elongated slots 49 through which the second condenser coils 44 extend.
In one example manufacturing process, the first and second condenser rows 38, 40 are of approximately equal length in the unbent state. An end portion of the condenser 18 is bent to provide a condenser in the bent state, shown in Figure 3. The condenser 18 shown in Figure 3 includes an elongated portion 50 and a short leg or bent portion 52, which is supported by the tube sheet 46. The second condenser coils 44 are spaced from the tube sheet 46 in the bent state since the distance about the exterior of the condenser 18 is greater than the distance about the interior of the condenser 18.
Referring to Figures 3 and 4a, the shroud 32 includes a lateral wall 58 having an orifice 60 that receives the fan 30. A side wall 62 extends generally perpendicularly from the lateral wall 58 in the example shown. A flange 64 extends outwardly from the side wall 62 and away from the lateral wall 58 at an angle that is acute from the side wall 62 (best shown in Figure 5). The flange 64 terminates such that it leaves the first and second condenser coils 42, 44 exposed in the example shown. The exterior surface of the second condenser row is exposed and unobstructed by the shroud.
The tube sheet 46 includes a first wall portion 54 bent at an angle relative to the surface 51 to complimentarily engage the flange 64. The flange 64 and first wall portion 54 respectively include holes 66, 68 that align with one another for receiving fasteners 67, best shown in Figure 4a-5. In this manner, the shroud 32 is mounted on the condenser 18 while obstructing a minimal portion of the condenser 18 to ensure its efficient operation. The tube sheet 46 also includes a second wall portion 56 that is spaced from the first wall portion 54 in the example shown. The second wall portion 56 is arranged at a generally right angle relative to the surface 51. A lower portion of the second wall portion 56 includes a hole 70 that aligns with the hole 72 in a perimeter wall 13 extending from the base pan 12. A fastener 71 secures the base pan 12 and condenser 32 to one another with a fastener 71.
The top cover 34 is supported between the condenser 18 and the shroud 32. An upper portion of the second wall portion 56 includes a hole 70
(Figures 2 and 3) that is aligned with a corresponding hole 72 (Figure 4a) in the top cover 34 for receiving a fastener 71. In this manner, the condenser 18 is mounted and secured to the housing of the unit 10.
Although example embodiments of this invention have been disclosed, a worker of ordinary skill in this art would recognize that certain modifications would come within the scope of this invention. For that reason, the following claims should be studied to determine the true scope and content of this invention.
