Methods of installing and using the heating and
cooling unit 100 are also disclosed. FIG.1 generally depicts the heating andcooling unit 100 as a whole. In certain embodiments, the heating andcooling unit 100 may be a single package vertical (SPV) heating and cooling unit. The heating andcooling unit 100 may be any type of heating and cooling unit. The heating andcooling unit 100, or aspects thereof, may be used in residential or commercial settings. For example, the heating andcooling 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 andcooling unit 100 may be installed into an opening that is made into an outside wall. Additionally, the heating andcooling 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 andcooling unit 100 may be in communication with the interior space, while another portion of the heating andcooling unit 100 may be in communication with the surrounding ambient environment. For example, the heating andcooling unit 100 may be located about an exterior wall, with part of the heating andcooling unit 100 positioned within the interior space and part of the heating andcooling unit 100 positioned outside. - As depicted in
FIG. 2 , the heating andcooling unit 100 may include aheating system 102 and acooling system 104. Theheating system 102 may be generally disposed above thecooling system 104 or vice versa. In some instances, theheating system 102 may include a condensing heat exchanger. Any type of heating system may be used herein. Thecooling system 104 may include a refrigeration cycle air conditioner or the like. Any type of cooling system may be used herein. Likewise, any type of heating or refrigeration circuit may be used herein. - The heating and
cooling unit 100 may include anexterior casing 106. Theexterior casing 106 may be a single panel or a number of panels formed together. Ahorizontal division panel 108 may be disposed within thecasing 106. Thedivision panel 108 generally may separate aheating system compartment 110 from acooling system compartment 112. Theexterior casing 106 of theheating system compartment 110 may include a removable front panel 114 (as depicted inFIG. 1 ) for accessing one or more components of the heating andcooling unit 100. For example, the removablefront panel 114 may provide access to acombustion compartment 116. Theexterior casing 106 and the panels thereof may be made out of sheet metal and similar types of substantially rigid substrates. - As depicted in
FIG. 3 , thecombustion compartment 116 may include, among other things, aburner box 118, aninducer blower 120, and anexhaust flue 122. Other components of theheating system 102 may be disposed within thecombustion compartment 116. Thecombustion compartment 116 also may include a drainage system including a collector box (cold side) 124, atrap 126, and aconvertible drain 128. One ormore drainage tubes 130 may connect theexhaust flue 122 with thecollector box 124, thecollector box 124 with thetrap 126, and thetrap 126 with theconvertible drain 128. As depicted inFIG. 1 , theconvertible drain 128 may be in communication with anopening 132 in a side of theexterior casing 106 or in communication with anopening 134 in the removablefront panel 114 depending on the arrangement of theconvertible drain 128 and external space limitations. - For example, as depicted in
FIGS. 4-9 , theconvertible drain 128 may include ahose 136. In some instances, thehose 136 may be flexible. In other instances, thehose 136 may include a fixed bend along its length. Theconvertible drain 128 also may include adrain adapter 138 having a first end with an inlet 140 (which thehose 136 is attachable to) and a second end with anoutlet 142. In some instances, theinlet 140 may be angled relative to theoutlet 142. - The
drain adapter 138 also may include anattachment bracket 144. A correspondingkey hole 146 may be disposed in thedivision panel 108. Thekey hole 146 may include two configurations. In some instances, thekey 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 inFIG. 9 , theattachment bracket 144 may be configured to mate with thekey hole 146 to secure thedrain adapter 138 against thedivision panel 108 in a first configuration with theoutlet 142 facing a side of the heating andcooling unit 100. In some instances, however, a clearance on the side of the heating andcooling 100 may not allow for drainage thereabout. In such instances, as depicted inFIG. 7 , theattachment bracket 144 may be configured to mate with thekey hole 146 to secure thedrain adapter 138 against thedivision panel 108 in a second configuration with theoutlet 142 facing a front of the heating andcooling unit 100. In some instances, thehose 136 may be rotated to accommodate the second positioned from the first potion and vice versa. Other configurations may be used herein. - The

Theattachment hole 150 may be used to attach theplatform 148 to thedivision panel 108 by way of a fastener, such as a screw, a bolt, or the like, after theattachment bracket 144 is positioned within thekey hole 146. Theattachment bracket 144 may extend down from thebottom platform 148. - The
drain adapter 138 also may include aflange 152 extending upward from thebottom platform 148. Theflange 152 may be disposed about theoutlet 142. Theflange 152 may be configured to form a seal about theopening 132 in the side panel of the heating andcooling unit 100 when in the first configuration. Similarly, theflange 152 may be configured to form a seal about theopening 134 in the removablefront panel 114 when in the second configuration. - A
front surface 154 of thedrain adapter 138 may extend out from theflange 152 to form alip 156 therebetween. Thefront surface 154 may be configured to mate with theopening 132 in the side panel when in the first configuration or mate with theopening 134 in the removablefront panel 114 when in the second configuration. In some instances, there may be a slight clearance between the opening 134 in the removablefront panel 114 and thelip 156 in order to facilitate the removal of the removablefront panel 114. As depicted inFIG. 1 , aremovable cover 158 may be used to cover theunoccupied opening 132 in the side panel or theunoccupied opening 134 in the removablefront panel 114 depending on the orientation of thedrain adapter 138. Other components and other configurations may be used herein. - Due to space constraints, and in order to fit the various components within the size of the existing
combustion compartment 116, theburner box 118 may be mounted to a substantiallyvertical vestibule panel 160 within thecombustion compartment 116 in a sideways orientation. For example, as depicted inFIGS. 10-12 , afirst mounting bracket 162 may be attachable to thevestibule panel 160. Thefirst mounting bracket 162 also may be attachable to aninner wall 163 on afirst side 164 of theburner box 118. Likewise, asecond mounting bracket 166 may be attachable to thevestibule panel 160. Thesecond mounting bracket 166 may be attachable to anouter wall 167 on asecond side 168 of theburner box 118. Thefirst mounting bracket 162 may be spaced apart from thesecond mounting bracket 166 such that theburner box 118 is slidable between thefirst mounting bracket 162 and thesecond mounting bracket 166. In this manner, theburner box 118 may be inserted next to the first and second mountingbrackets first mounting bracket 162 and thesecond mounting bracket 166. - As depicted in
FIGS. 13-16 , the first and second mountingbrackets support protrusion 170 configured to mate with acorresponding alignment hole 172 in thevestibule panel 160. In addition, in order to secure the first and second mountingbrackets vestibule panel 160 and theburner box 118, the first and second mountingbrackets vestibule attachment hole 174 and a burnerbox attachment hole 176. Any number of alignment andsupport protrusions 170, vestibule attachment holes 174, and/or burner box attachment holes 176 may be used. A fastener, such as a screw, a bolt, or the like may be inserted into thevestibule attachment hole 174 and acorresponding attachment hole 178 in thevestibule panel 160 for securing the first and second mountingbrackets vestibule panel 160. Likewise, a fastener, such as a screw, bolt, or the like may be inserted into the burnerbox attachment hole 176 and acorresponding attachment hole 180 in theburner box 118 for securing the first and second mountingbrackets burner box 118. In some instances, thesecond mounting bracket 166 may not include a fastener for attaching theburner box 118. In addition, the first and second mountingbrackets box alignment protrusion 182 configured to mate with acorresponding alignment hole 184 in the burner box. Any number of burnerbox alignment protrusions 182 may be used. Other components and other configurations may be used herein. - Referring back to
FIGS. 2 and 3 , acontrol panel 186 may be disposed within thecombustion compartment 116. Also due to space constraints, and in order to fit the various components within thecombustion compartment 116, thecontrol panel 186 may be removably attached to thecollector box 124. For example, as depicted inFIGS. 17-22 , thecollector box 124 may include achannel 188, and thecontrol panel 186 may include acorresponding slot 190. Any number ofchannels 188 andslots 190 may be used. Theslot 190 may be configured to slidably mate with thechannel 188. In some instances, thecontrol panel 186 may include an L-shapedbase 192 with theslot 190 formed therein. - A
tab 194 may be disposed on thecollector box 124 adjacent to thechannel 188. Thetab 194 may be configured to removably secure theslot 190 within thechannel 188. For example, thetab 194 may be elastic such that it may slide forward when theslot 190 is slid into thechannel 188. Thetab 194 may rest in anotch 196 adjacent to theslot 190 to prevent theslot 190 from sliding out of thechannel 188. To remove thecontrol panel 186, thetab 194 may be pressed out of thenotch 196 to allow theslot 190 to slide out of thechannel 188. In this manner, thecontrol panel 186 may no longer be attached to the removablefront panel 114 as is typically done. The disclosed configuration enables thecontrol panel 186 to be readily removed from thecombustion compartment 116 to access the other components, such as theburner box 118 and/or theinducer blow 120. Other components and other configurations may be used herein. - Referring back to
FIG. 2 , theexterior casing 106 about thecombustion compartment 116 may include an air inlet 198 (louvers) in communication with the outside ambient environment. For example, thecombustion compartment 116 may be generally on a non-conditioned space side of the heating andcooling unit 100. That is, thecombustion compartment 116 may be generally in communication with the outside ambient environment and substantially sealed off from the interior space. - 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 thecombustion compartment 116, which may be on the non-conditioned space side of the heating andcooling 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 thecombustion compartment 116 and into the interior space via thedrain adapter 138. -
FIG. 23 depicts aheat exchanger assembly 200, which may be disposed adjacent to thecombustion compartment 116. Theheat exchanger assembly 200 and thecombustion compartment 116 may be separated by thevestibule panel 160. Theheat exchanger assembly 200 may include, among other things, anair inlet 202, an air outlet 204 (depicted inFIG. 2 ), aprimary heat exchanger 206, asecondary heat exchanger 208, and atransition box 210 between theprimary heat exchanger 206 and thesecondary heat exchanger 208. Theprimary heat exchanger 206 may be in communication with theburner box 118 by way of one or more openings in thevestibule panel 160. - The
heat exchanger assembly 200 may be generally on a conditioned space side of the heating andcooling unit 100. That is, theheat exchanger assembly 200 may be generally in communication with the interior space and substantially sealed off from the outside environment. For example, theair inlet 202 may receive air from the interior space, and theair outlet 204 my provide heat air to the interior space. Other components and other configurations may be used herein. - Referring back to
FIG. 2 , thecooling system 104 may be generally disposed within thecooling system compartment 112 located beneath thedivision panel 108. Thecooling system compartment 112 may include, among other things, aseparator panel 212 that separates a conditioned space side from a non-conditioned space of thecooling system compartment 112. Anevaporator 214 may be located on the conditioned space side ofseparator panel 212, and acompressor 216 andcondenser 215 may be located on a non-conditioned space side of the separator panel. - A
base member 218 may be disposed about a bottom of thecooling system compartment 112. Thebase member 218 may be slid in and out of thecooling system compartment 112. As depicted inFIGS. 24-28 , thebase member 218 may include a substantially horizontalmain body 220 configured to support one or more components of thecooling system 104 thereon, such as theevaporator 214 and/or thecompressor 216, among others. Themain body 220 may include a conditionedspace portion 222 about a front of themain body 220 and anon-conditioned space 224 portion about a rear of themain body 220. A substantiallyvertical separation wall 226 may extend up from themain body 220. In some instances, as depicted inFIGS. 29 and 30 , theseparator panel 212 may be disposed on top of theseparation wall 226. In this manner, theseparation wall 226 and theseparator panel 212 may separate the conditionedspace portion 222 from thenon-conditioned space portion 224. - The
base member 218 may include alip 228 formed at least partially about thenon-conditioned space portion 224. In some instances, thelip 228 may extend along the sides of thenon-conditioned space portion 224 and/or along a perimeter of thenon-conditioned space portion 224. Adrainage hole 230 may extend through thenon-conditioned space portion 224. Thedrainage hole 230 may be in communication with the outside ambient environment. In some instances, thedrainage hole 230 may include twodrainage holes 230 disposed at the back corners of thenon-conditioned space portion 224. Any number ofdrainage holes 230 may be used. To facilitate drainage, asurface 232 of thenon-conditioned space portion 224 may sloped towards thedrainage hole 230. - The conditioned
space portion 222 of thebase member 218 may include adrain pan 234. Thedrain pan 234 may receive condensate from theevaporator 214. In some instances, theseparation wall 226 and thedrain pan 234 may at least partially form anevaporator compartment 236 therebetween. Adrainage tube 238 may be in fluid communication with thedrain pan 234. In this manner, asurface 240 of thedrain pan 234 may be sloped towards thedrainage tube 238. In some instances, a substantiallyvertical sealing rib 242 may be disposed within thedrain pan 234. The sealingrib 242 may be configured to make contact with and deform one or more fins on a coil of theevaporator 214 to create a seal between the coil and the sealingrib 242 to force liquid forward into thedrain pan 234 towards thedrainage tube 238 and to prevent airflow therebetween. As depicted inFIGS. 27 and 28 , thedrain pan 234 also may include one or moreintegrated holes 244 disposed for mounting afilter catch 246. - The
drainage tube 238 may be disposed beneath thedrain pan 234. To ensure that thedrainage tube 238 does not break off during installation or maintenance, aprotective box 248 may be disposed about thedrainage tube 238. In addition, to slide thebase member 218 in and out of the cooling system compartment, a molded handled 250 may be formed about the conditionedspace portion 222. For example, the molded handle may 250 be disposed beneath thedrain pan 234. In some instances, twohandles 250 may be molded beneath thedrain pan 234. In some instances, one or moreadditional handles 251 may be positioned adjacent to thehandles 250. Theadditional handles 251 may be used transport thebase member 218 after it has been removed. - In certain embodiments, the
base member 218 may include aridge 252 disposed on a bottom of themain body 220 opposite theseparation wall 226. Theridge 252 may form a seal under themain body 220 between the conditionedspace portion 222 and the non-condition spacedportion 224. For example, theridge 252 may abut an interior wall (or ridge) of theexterior casing 106 to form a seal therebetween. In some instances, thebase 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
FIGS. 29 and 30 , atube chase 254 may be attached to theseparator panel 212 in order to pass tubing, wiring, and/or other components between the conditionedspace portion 222 and the non-condition spacedportion 224 of thecooling system compartment 112.

Theattachment groove 270 may extend at least partially about a perimeter of the tube chasemain body 256. In some instances, thetube chase cover 262 may include anexterior surface 272 configured to form a seal with the side panel of the heating andcooling unit 100. - To attach the tube chase
main body 256 to the removabletube chase cover 262, the tube chasemain body 256 may include anattachment protrusion 274. Likewise, the removabletube chase cover 262 may include anattachment hole 276 configured to mate with theattachment protrusion 274. In addition, the tube chasemain body 256 may include an attachment bore 278 configured to receive a fastener therein, and the removabletube chase cover 262 may include anarm 280 having anattachment hole 282 therethrough. Theattachment hole 282 may be configured to receive a fastener therein when the attachment bore 278 is aligned with theattachment hole 282. In this manner, the removabletube case cover 262 may be rotatably attached to the tube casemain body 256 by positioning theattachment hole 276 within theattachment protrusion 274 and rotating thetube chase cover 262 about the tube chasemain body 256 so that theattachment 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 acompressor 216. As depicted inFIGS. 34 and 35 , thecompressor 216 may include anelectric feedthrough 284. Theelectric feedthrough 284 may provide a passage for one or more electrical components between the compressor can (e.g., high pressure side of the compressor 216) and the ambient environment. Because theelectric feedthrough 284 is positioned between the high pressure side of thecompressor 216 and the ambient, it may be prone to blow offs. In order to prevent theelectric feedthrough 284 from becoming a projectile, a compressorpower supply plug 286 may be attached to theelectric feedthrough 284. Thecompressor supply plug 286 may also form an electrical connection with theelectric feedthrough 284. - As depicted in
FIGS. 36-38 , thecompressor supply plug 286 may include amain body 288 attachable to theelectric feedthrough 284. Themain body 288 may generally form a plug having one or more electricalterminal connections 290 therein for connecting one ormore wires 292 to theelectric feedthrough 284. For example, in some instances, theelectric feedthrough 284 may include one or more male terminals, and themain body 288 may include one or more corresponding female terminals, or vice versa. Thecompressor supply plug 286 also may include aflange 294 extending from themain body 288. In some instances, themain body 288 andflange 294 may be single molded piece. - The
flange 294 may include anaperture 296 extending therethrough. Thecompressor 216 may include acorresponding stud 298 positioned adjacent to theelectric feedthrough 284. Thestud 298 may be securely attached to the compressor can. To secure themain body 288 to theelectric feedthrough 284, thestud 298 may be positioned within theaperture 296. That is, theaperture 296 may be configured to receive thestud 298 for securing themain body 288 to thecompressor 216. In this manner, a fastener (such as a nut or other attachment device) may be threaded onto thestud 298 to capture themain body 288 against theelectric feedthrough 284 by way of theflange 294. In addition, theaperture 296 andstud 298 may collectively act as a key to ensure that themain body 288 is properly aligned with theelectric feedthrough 284. In some instances, acap 300 may be positioned over thecompressor supply plug 286. In other instances, thecap 300 may be omitted. - The
main body 288 and/or theflange 294 may include a sealingsurface 300 that mates to a top surface of the compressor can 216 and theelectrical feedthrough 284. The sealingsurface 300 may prevent moisture from entering thecompressor supply plug 286, thereby preventing corrosion from forming between thefemale terminal 290 and male terminals protruding fromelectrical feedthrough 284. - The
compressor supply plug 286 may be used with a compressor in a heating and cooling unit as described herein, or thecompressor supply plug 286 may be used with compressors in other application. Thecompressor supply plug 286 may be used with any compressor. Other components and other configurations may be used herein. - Although specific embodiments of the disclosure have been described, numerous other modifications and alternative embodiments are within the scope of the disclosure. For example, any of the functionality described with respect to a particular device or component may be performed by another device or component. Further, while specific device characteristics have been described, embodiments of the disclosure may relate to numerous other device characteristics. Further, although embodiments have been described in language specific to structural features and/or methodological acts, it is to be understood that the disclosure is not necessarily limited to the specific features or acts described. Rather, the specific features and acts are disclosed as illustrative forms of implementing the embodiments. Conditional language, such as, among others, “can,” “could,” “might,” or “may,” unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain embodiments could include, while other embodiments may not include, certain features, elements, and/or steps. Thus, such conditional language is not generally intended to imply that features, elements, and/or steps are in any way required for one or more embodiments.
