Description
- The present application relates generally to refrigeration systems and more particularly relates to a modular evaporator and components thereof for use within a walk-in cooler and other types of refrigeration systems and having a number of different service clip configurations.
- Modern air conditioning and refrigeration systems provide cooling, ventilation, and humidity control for all or part of an enclosure such as a building, a cooler, and the like. Generally described, the refrigeration cycle includes four basic stages to provide cooling. First, a vapor refrigerant is compressed within a compressor at high pressure and heated to a high temperature. Second, the compressed vapor is cooled within a condenser by heat exchange with ambient air drawn or blown across a condenser coil by a fan and the like. Third, the liquid refrigerant is passed through an expansion device that reduces both the pressure and the temperature of the liquid refrigerant. The liquid refrigerant is then pumped within the enclosure to an evaporator. The liquid refrigerant absorbs heat by blowing or drawing air across the evaporator coil as the liquid refrigerant changes to vapor. Finally, the vapor is returned to the compressor and the cycle repeats. Various alternatives on this basic refrigeration cycle are known and also may be used herein.
- Conventional walk-in coolers, such as those typically found in the food service industry and the like, generally have an evaporator therein similar to that described above. The evaporator typically is hung from the ceiling of the cooler. The evaporator thus may take up space within the cooler that could have been used for storage or other purposes. The evaporator also may present a hazard in that the evaporator may extend downward into the usual standing area so as to present a risk of injury for individuals walking therein. Likewise, a condensate drain may hang below the evaporator. The condensate drain also may take up useful storage space and itself may be an injury risk.
- Typical evaporators generally also require extensive disassembly so as to repair and/or replace a component therein such as a fan and the like. Such disassembly procedures generally involves shutting down the cooler and may involve transferring all of the items stored therein. Moreover, even repairs that do not involve shutting down the cooler at least require the workman to work in the refrigerated space for an extended period of time. Repairing an existing evaporator thus may be a somewhat costly and time intensive procedure. Similarly, installing a new evaporator may be difficult given the typical weight involved and the difficulty in maneuvering in the close spaces typically found therein.
- There is a therefore a desire for an improved evaporator design for use within walk-in coolers and other types of refrigeration systems. Such an improved evaporator design preferably may take up less storage space therein and create less of an injury hazard while providing easy access thereto for repair and/or replacement of the components therein.
- The present application and the resultant patent thus provide an evaporator. The evaporator may include a housing, a fan module removably positioned within the housing, a number of retainer clips positioned on the fan module, and a number of retainer clip slots positioned on the housing. The retainer clips and the retainer clips slots may include a clip attachment configuration and a service clip configuration.
- The present application and the resultant patent further provide an evaporator. The evaporator may include a housing, a fan module removably positioned within the housing, a number of retainer clips positioned on the fan module, a number of retainer clip slots positioned on the housing, a service clip positioned on the fan module, and a service clip slot positioned on the housing. The retainer clips and the retainer clips slots may include a clip attachment configuration and the service clip and the service clip slot may include a service clip configuration.
- The present application and the resultant patent further provide an evaporator. The evaporator may include a housing, a fan module removably positioned within the housing, a number of retainer clips positioned on the fan module, a number of retainer clip slots positioned on the housing, a support rail within the housing, and a number of support rail slots positioned within the support rail. The retainer clips and the retainer clips slots may include a clip attachment configuration and the retainer clips and the support rail slots may include a service clip configuration.
- These and other features of the present application and the resultant patent will become apparent to one of ordinary skill in the art upon review of the following detailed description when taken in conjunction with the several drawings and the appended claims.

Thefan housing 340 may be made out of molded plastics, metals, and other types of substantially rigid materials. Thefan housing 340 may have a number of mountingrails 350 positioned thereon. The mountingrails 350 may mate with a number of top panel rails 360 positioned about thetop panel 140. The use of the mountingrails 350 and the top panel rails 360 allows thefan module 330 as a whole to slide in and out of thehousing 130 of theevaporator 100 as a whole. Afan wiring harness 365 and the like may extend along the top panel rails 360 and/or otherwise within thehousing 130 and may be in communication with thefan module 330 and theelectrical module 240 and/or other controls as thefan module 330 slides therein. - The
fan housing 340 also may include a lockingmember 370 positioned thereon. The lockingmember 370 may be biased into the locked positioned. The lockingmember 370 may mate with a receivingmember 380 positioned about thetop panel 140 or otherwise (including the reverse). When thefan module 330 is slid into thehousing 130 of theevaporator 100, the lockingmember 370 and the receivingmember 380 may cooperate to lock thefan module 330 into place. Other types of locking mechanism may be used herein. - The
fan module 330 may include afan assembly 385 mounted within thefan housing 340. Thefan assembly 385 may have afan 390 mounted on afan mounting bracket 395. Thefan 390 may be a backward incline centrifugal fan and the like. The backward incline centrifugal fan may have an overall reduced height as compared to conventional axial refrigeration fans. A backward incline centrifugal fan generally is used in air handlers as opposed to refrigeration units due to the ability of the fan to overcome high static pressure loads associated with duct work. Thefan 390 may be a variable speed fan. Thefan 390 pulls the airflow through thecoil assembly 260 and turns the flow into the cooler 110 or other refrigerated space. Thefan assembly 385 also may include afan motor 400, one ormore air plenums 410, and electronics and other controls. The electronics and the other components may be placed in communication with theelectrical module 240 via thewiring harness 365 via one or more quick disconnect fittings or otherwise. Other types offans 390,fan motors 400, and controls may be used herein. A replaceable venture ring may be positioned about thefan 390. Other components and other configurations may be used herein. - The
fan module 330 also includes agrill 420 so as to enclose one end of thehousing 340. Thegrill 420 may be made out of molded plastics, metals, and other types of substantially rigid materials. Thegrill 420 may have any size, shape, or configuration. Thegrill 420 may be attached by a number of clips or other attachment means for easy access thereto and for easy cleaning. - In use, the
evaporator 100 may be attached to theceiling 115 of the cooler 110 or other type of structure. A template may be used to align the location of the mountingbrackets 170 and the mountingapertures 180 so as to drill the appropriate holes and the like. Advantageously, thefan module 330 need not be positioned within thehousing 130. Removing thefan module 330 makes theoverall evaporator 100 lighter and makes attachment to the cooler 110 considerably easier than may be possible with known units. Thecoil assembly 260 and theelectrical module 240 with the related wiring may be premounted to thehousing 130. Once thehousing 130 is installed, thefan module 330 may be slid within thehousing 130 via the mountingrails 350 and the top panel rails 360. The electronics and other controls are prewired such that communication with theelectrical module 340 is established as thefan module 330 slides therein.Multiple fan modules 330 may be used in asingle housing 130. - Access to the
electrical module 340 and thecoil assembly 260 may be provided via theservice access panel 220. Likewise, thefan module 330 may be quickly and easily removed from thehousing 130 for repair, replacement, and/or cleaning. For example, removing thefan module 330 provides access for coil cleaning, drain pan cleaning, and the like. Thefan module 330 may be slid out to an intermediate position or a retracted position or the lockingmember 370 may be released such that thefan module 330 may be removed completely. Thefan module 330 thus may have at least an installed position, a retracted position, and a removed position. Advantageously, thefan module 330 may be removed from thehousing 130 of theevaporator 100 and repaired outside of the cooler 110. - The
evaporator 100 thus provides ease of installation and ease of access with a relatively low profile. For example, if existing evaporators are generally in excess of a height of about fourteen (14) inches (about 35.56 centimeters), the evaporator described herein may be about eleven (11) inches (about 27.94 centimeter) or so. These dimensions are for the purpose of comparison only and any height may be used herein. Nonetheless, theevaporator 100 described herein provides more storage room for the cooler 110 given the reduced profile. Likewise, the risk of injury also may be reduced herein. -
