Described below are embodiments of a heating and cooling unit 100 (as well as individual components of the heating and cooling unit 100). Methods of installing and using the heating and cooling unit 100 are also disclosed. FIG.1 generally depicts the heating and cooling unit 100 as a whole. In certain embodiments, the heating and cooling unit 100 may be a single package vertical (SPV) heating and cooling unit. The heating and cooling unit 100 may be any type of heating and cooling unit. The heating and cooling unit 100, or aspects thereof, may be used in residential or commercial settings. For example, the heating and cooling unit 100 may be used to heat and/or cool an interior space, such as a room, an apartment, a house, a building, etc. In some instances, the heating and cooling unit 100 may be installed into an opening that is made into an outside wall. Additionally, the heating and cooling unit 100 may be installed adjacent to an outside wall with a wall sleeve connecting the unit to the outdoors. That is, a portion of the heating and cooling unit 100 may be in communication with the interior space, while another portion of the heating and cooling unit 100 may be in communication with the surrounding ambient environment. For example, the heating and cooling unit 100 may be located about an exterior wall, with part of the heating and cooling unit 100 positioned within the interior space and part of the heating and cooling unit 100 positioned outside.
As depicted in
The heating and cooling unit 100 may include an exterior casing 106. The exterior casing 106 may be a single panel or a number of panels formed together. A horizontal division panel 108 may be disposed within the casing 106. The division panel 108 generally may separate a heating system compartment 110 from a cooling system compartment 112. The exterior casing 106 of the heating system compartment 110 may include a removable front panel 114 (as depicted in
As depicted in
For example, as depicted in
The drain adapter 138 also may include an attachment bracket 144. A corresponding key hole 146 may be disposed in the division panel 108. The key hole 146 may include two configurations. In some instances, the key hole 146 may resemble the outline of Mickey Mouse's head, i.e., a main circle with two semi-circles or mouse ears extending therefrom. In this manner, as depicted in
The drain adapter 138 may include a bottom platform 148 having an attachment hole 150 therethrough. The attachment hole 150 may be used to attach the platform 148 to the division panel 108 by way of a fastener, such as a screw, a bolt, or the like, after the attachment bracket 144 is positioned within the key hole 146. The attachment bracket 144 may extend down from the bottom platform 148.
The drain adapter 138 also may include a flange 152 extending upward from the bottom platform 148. The flange 152 may be disposed about the outlet 142. The flange 152 may be configured to form a seal about the opening 132 in the side panel of the heating and cooling unit 100 when in the first configuration. Similarly, the flange 152 may be configured to form a seal about the opening 134 in the removable front panel 114 when in the second configuration.
A front surface 154 of the drain adapter 138 may extend out from the flange 152 to form a lip 156 therebetween. The front surface 154 may be configured to mate with the opening 132 in the side panel when in the first configuration or mate with the opening 134 in the removable front panel 114 when in the second configuration. In some instances, there may be a slight clearance between the opening 134 in the removable front panel 114 and the lip 156 in order to facilitate the removal of the removable front panel 114. As depicted in
Due to space constraints, and in order to fit the various components within the size of the existing combustion compartment 116, the burner box 118 may be mounted to a substantially vertical vestibule panel 160 within the combustion compartment 116 in a sideways orientation. For example, as depicted in
As depicted in
Referring back to
A tab 194 may be disposed on the collector box 124 adjacent to the channel 188. The tab 194 may be configured to removably secure the slot 190 within the channel 188. For example, the tab 194 may be elastic such that it may slide forward when the slot 190 is slid into the channel 188. The tab 194 may rest in a notch 196 adjacent to the slot 190 to prevent the slot 190 from sliding out of the channel 188. To remove the control panel 186, the tab 194 may be pressed out of the notch 196 to allow the slot 190 to slide out of the channel 188. In this manner, the control panel 186 may no longer be attached to the removable front panel 114 as is typically done. The disclosed configuration enables the control panel 186 to be readily removed from the combustion compartment 116 to access the other components, such as the burner box 118 and/or the inducer blow 120. Other components and other configurations may be used herein.

As noted above, the heating system 102 may include a condensing heat exchanger. A drainage system for the condensing heat exchanger may be disposed within the combustion compartment 116, which may be on the non-conditioned space side of the heating and cooling unit 100 because it is exposed to the outside ambient environment. Typically, drainage from a condensing heat exchanger is routed to the outside environment, with, for example, the drainage line being buried underground. Here, however, the drainage line may be routed through the combustion compartment 116 and into the interior space via the drain adapter 138.
The heat exchanger assembly 200 may be generally on a conditioned space side of the heating and cooling unit 100. That is, the heat exchanger assembly 200 may be generally in communication with the interior space and substantially sealed off from the outside environment. For example, the air inlet 202 may receive air from the interior space, and the air outlet 204 my provide heat air to the interior space. Other components and other configurations may be used herein.
Referring back to
A base member 218 may be disposed about a bottom of the cooling system compartment 112. The base member 218 may be slid in and out of the cooling system compartment 112. As depicted in
The base member 218 may include a lip 228 formed at least partially about the non-conditioned space portion 224. In some instances, the lip 228 may extend along the sides of the non-conditioned space portion 224 and/or along a perimeter of the non-conditioned space portion 224. A drainage hole 230 may extend through the non-conditioned space portion 224. The drainage hole 230 may be in communication with the outside ambient environment. In some instances, the drainage hole 230 may include two drainage holes 230 disposed at the back corners of the non-conditioned space portion 224. Any number of drainage holes 230 may be used. To facilitate drainage, a surface 232 of the non-conditioned space portion 224 may sloped towards the drainage hole 230.
The conditioned space portion 222 of the base member 218 may include a drain pan 234. The drain pan 234 may receive condensate from the evaporator 214. In some instances, the separation wall 226 and the drain pan 234 may at least partially form an evaporator compartment 236 therebetween. A drainage tube 238 may be in fluid communication with the drain pan 234. In this manner, a surface 240 of the drain pan 234 may be sloped towards the drainage tube 238. In some instances, a substantially vertical sealing rib 242 may be disposed within the drain pan 234. The sealing rib 242 may be configured to make contact with and deform one or more fins on a coil of the evaporator 214 to create a seal between the coil and the sealing rib 242 to force liquid forward into the drain pan 234 towards the drainage tube 238 and to prevent airflow therebetween. As depicted in
The drainage tube 238 may be disposed beneath the drain pan 234. To ensure that the drainage tube 238 does not break off during installation or maintenance, a protective box 248 may be disposed about the drainage tube 238. In addition, to slide the base member 218 in and out of the cooling system compartment, a molded handled 250 may be formed about the conditioned space portion 222. For example, the molded handle may 250 be disposed beneath the drain pan 234. In some instances, two handles 250 may be molded beneath the drain pan 234. In some instances, one or more additional handles 251 may be positioned adjacent to the handles 250. The additional handles 251 may be used transport the base member 218 after it has been removed.
In certain embodiments, the base member 218 may include a ridge 252 disposed on a bottom of the main body 220 opposite the separation wall 226. The ridge 252 may form a seal under the main body 220 between the conditioned space portion 222 and the non-condition spaced portion 224. For example, the ridge 252 may abut an interior wall (or ridge) of the exterior casing 106 to form a seal therebetween. In some instances, the base member 218 may be a single integrated member. That is, the base member 218 (and its various components) may be molded as a single piece of plastic or the like. Other components and other configurations may be used herein.

As depicted in
The tube chase main body 256 may include an attachment groove 270 for attaching the tube chase main body 256 to separator panel 212. The attachment groove 270 may extend at least partially about a perimeter of the tube chase main body 256. In some instances, the tube chase cover 262 may include an exterior surface 272 configured to form a seal with the side panel of the heating and cooling unit 100.
To attach the tube chase main body 256 to the removable tube chase cover 262, the tube chase main body 256 may include an attachment protrusion 274. Likewise, the removable tube chase cover 262 may include an attachment hole 276 configured to mate with the attachment protrusion 274. In addition, the tube chase main body 256 may include an attachment bore 278 configured to receive a fastener therein, and the removable tube chase cover 262 may include an arm 280 having an attachment hole 282 therethrough. The attachment hole 282 may be configured to receive a fastener therein when the attachment bore 278 is aligned with the attachment hole 282. In this manner, the removable tube case cover 262 may be rotatably attached to the tube case main body 256 by positioning the attachment hole 276 within the attachment protrusion 274 and rotating the tube chase cover 262 about the tube chase main body 256 so that the attachment hole 282 is aligned with the attachment bore 278. Other components and other configurations may be used herein.
As noted above, the cooling system 104 may include a compressor 216. As depicted in
As depicted in
The flange 294 may include an aperture 296 extending therethrough. The compressor 216 may include a corresponding stud 298 positioned adjacent to the electric feedthrough 284. The stud 298 may be securely attached to the compressor can. To secure the main body 288 to the electric feedthrough 284, the stud 298 may be positioned within the aperture 296. That is, the aperture 296 may be configured to receive the stud 298 for securing the main body 288 to the compressor 216. In this manner, a fastener (such as a nut or other attachment device) may be threaded onto the stud 298 to capture the main body 288 against the electric feedthrough 284 by way of the flange 294. In addition, the aperture 296 and stud 298 may collectively act as a key to ensure that the main body 288 is properly aligned with the electric feedthrough 284. In some instances, a cap 300 may be positioned over the compressor supply plug 286. In other instances, the cap 300 may be omitted.
The main body 288 and/or the flange 294 may include a sealing surface 300 that mates to a top surface of the compressor can 216 and the electrical feedthrough 284. The sealing surface 300 may prevent moisture from entering the compressor supply plug 286, thereby preventing corrosion from forming between the female terminal 290 and male terminals protruding from electrical feedthrough 284.
The compressor supply plug 286 may be used with a compressor in a heating and cooling unit as described herein, or the compressor supply plug 286 may be used with compressors in other application. The compressor supply plug 286 may be used with any compressor. Other components and other configurations may be used herein.
