Definitions
- This invention relates generally to evaporator units for air conditioning systems and, more particularly, to the construction and mounting of side panel structures for closing the ends thereof.
- conditioned air is discharged into an internal space through an air distribution or conditioning unit.
- air conditioning system often referred to as a split system, includes separate indoor and outdoor units.
- the outdoor unit includes a compressor, a heat exchanger and a fan.
- the indoor unit includes a heat exchanger and a fan. In operation, the indoor fan draws air into the indoor or evaporator unit, through an inlet thereof, and forces the air over the indoor heat exchanger and then out of the indoor unit, through an outlet opening therein.
- the outdoor fan draws outdoor air into the outdoor unit, and circulates it over the outdoor heat exchanger and then back out to ambient.
- a compressor causes a refrigeration fluid to circulate through and between the indoor/outdoor heat exchangers.
- the refrigerant absorbs heat from the air passing over that heat exchanger to cool the air.
- the outdoor heat exchanger absorbs heat from the refrigerant passing therethrough.
- Split type air conditioning units of this type are typically manufactured in a wide range of cooling capacities. Accordingly, the size of the indoor unit can range from a small compact relatively narrow unit up to a wide unit, of substantially the same height as the compact unit.
- a common approach for indoor units of a split type air conditioning system is to provide an elongate body with a covering arrangement which wraps over the top, front and bottom of the body, and then providing separate end panels to cover the ends thereof. Since it is important that these end covers are very securely fastened to the body, this attachment process generally involves considerable time and effort, as well as a number of fasteners.
- An evaporator unit for an air conditioning system includes a main body having a back panel and a front section defining an air inlet and an air outlet.
- the body defines an air flow path through the unit extending from the inlet to the outlet.
- An evaporator coil is supported in the body and within the air flow path.
- the unit includes an evaporator fan for causing air to flow along the air flowpath and through the evaporator coil where the air is cooled and water is removed therefrom, resulting in condensation.
- a pair of mounting brackets are mounted on a rear edge of the body end opening, and a pair of mating hinge brackets are mounted on the rear edge of the end panels, with the hinge brackets being easily engageable with the mounting brackets to hingeably mount the end panel to the body.
- a pair of fasteners then interconnects the front edge of the body and opening to the front edge of the end panel.
- the mounting brackets and hinge brackets are integrally formed as part of the body and end panel, respectively.
- the mounting bracket is of a female configuration and the hinge bracket is of a male configuration, and the two are interconnected by way of a snap-in arrangement.
- Fig. 1 is a perspective view of an evaporator unit in accordance with the present invention.
- Fig. 2 is an exploded view thereof.
- Fig. 3 is a partial perspective end view showing the right side thereof with the end cover removed.
- Fig. 4 is a partial perspective view showing a left side thereof with the end cover removed.
- Fig. 5A is a partial perspective view thereof with the side panel installed but in an open position.
- Fig. 5B is an expanded view of the Fig. 5 A embodiment.
- Fig. 5 C is an enlarged view of a portion of the Fig. 5 A embodiment.
- An evaporator unit embodying the present invention is shown at 11 as being installed with its rear side 12 against a lower portion of the wall, near the floor. Such a system may, as well, be installed with its rear side 12 against the ceiling of a room. For purposes of description, however, the unit 11 will be described as having a front side 13, top 14, a left end 16 and a right end 17, and a bottom 18.
- evaporator unit is shown in an exploded view to include all the various components prior to assembly. The sequence and manner of assembly will now be described.
- a back panel 21 forms the primary structural component and a portion of the housing of the evaporator unit.
- An upper closure assembly 22 is secured to the back panel 21 by first engaging an upper edge thereof over an upper edge of the back panel 21 and then securing the two components together with fasteners 23.
- the left and right internal side assemblies, 24 and 26 are attached to the back panel 21 by fasteners.
- the fan assembly 27 is then secured to the lower portion of the back panel 21 by fasteners 28.
- the next step in the assembly process is to install the evaporator coil 29 into the housing by placing its ends in the respective left and right internal side assemblies 24 and 26.
- the evaporator coil 29 is then secured in its installed position by a single screw at each end thereof which passes through the internal side assembly and into a tube sheet at the end of the evaporator coil 29.
- the evaporator coil 29 is so disposed within the evaporator compartment, which is partially defined by the pack panel 21 and the left and right internal side assemblies 24 and 26. However, it is still necessary to close the ends of the evaporator compartment to prevent the flow of air therethrough.
- left and right closure elements 31 and 32 which are simply placed in position without fasteners and then are held in place by engagement with the drain pan 33 which further defines the evaporator compartment.
- the drain pan 33 is secured in place by a fastener in each end to secure the respective left and right internal side assemblies 24 and 26 to the drain pan 33.
- a drain hose 34 is attached to a drainage element of the drain pan 33.
- a front panel 36 is then placed over the drain pan 33 and secured in place by fasteners attaching it to both the left and right internal side assemblies 24 and 26 and also to the fan deck portion of the back panel 21.
- a control box 37 is installed by snap fit into the left internal side assembly 24 and a stepping motor 38 is also secured to the side assembly 24.
- the blower compartment which is partially formed by the lower portion of the back panel 21 and by the fan assembly 27, has an air intake opening therein. This intake opening is partially closed by way of a grill 39 into which a plurality of filter elements 41 are placed.
- the next step is to connect the stepping motor 38 to a horizontal louver mechanism on the upper closure assembly 22 and the horizontal louver 42 is secured at its ends to the left and right internal side assemblies 24 and 26 and, in its intermediate portion, to the upper closure assembly 22.
- the left and right end covers, 43 and 44, are then secured to the respective left and right internal side assemblies 24 and 26 respectively, to complete the assembly process.
- evaporator unit is shown with its right end 17 being exposed, i.e., with its right end cover being removed to show an internal side assembly 45 with some of the internal components including a refrigerant connection tube 46 which provides fluid communication to the tubes within an internal heat exchanger, and a condensate drainage tube 47 that provides for drainage of condensate from a condensate pan when the unit is installed in an under-ceiling position.
- a refrigerant connection tube 46 which provides fluid communication to the tubes within an internal heat exchanger
- condensate drainage tube 47 that provides for drainage of condensate from a condensate pan when the unit is installed in an under-ceiling position.
- Located adjacent the rear side 12 are a pair of spaced main body brackets 48 and 49, near the top 14 and bottom 18 of the unit, respectively. These brackets are provided for securing the right end cover in a manner to be described hereinafter.
- FIG. 4 the left end 16 of the unit is shown in Fig. 4 with its cover being removed to expose an internal side assembly 50 with various components such as the evaporator coil 51 and an electronic control module 52.
- main body brackets 53 and 54 are provided adjacent the rear side 12, near the top 14 and bottom 18, respectively.
- the right end is again shown at 17 in Fig. 5 A, but with the right end cover 44 being mounted to the main body brackets 48 and 49 as shown. In the position shown, the right end cover 44 has been attached to the main body brackets 48 and 49 but the right end cover 44 has not yet been rotated forwardly to the closed position.
- the right end cover 44 comprises a rather flat end wall 57 and a side wall 58 extending substantially normally therefrom on all sides of the end wall 57.
- the edge 59 of the side wall 58 is engaged with the edge 61 of the body and is secured in that position by a single fastener.
- the main body bracket 49 includes a female connector 62 which is comprised of a pair of spaced tongues 63 and 64 forming a slot 66 therebetween the tongue 64 which is dispersed near the front side 13 of the unit is slightly longer than the tongue 63 as shown, and the slot 66 extends toward the body and terminates in a pocket 67 which extends substantially normally thereto.
- left and right end covers 43 and 44 may be very easily and quickly installed on or removed from the unit with only a single fastener then being used to secure each of the covers in place after they have been rotated to the closed position.
