Dnvw B. ZIPSEE TOENEYS United States Patent COOLER UNIT David B. Zipser, Baltimore, Md., assignor to Tenney Engineering, Inc., Newark, N. J., a corporation of New Jersey This invention relates to a cooler unit of the kind appropriate for the cooling of so-called walled-in refrigerators and adapted to be mounted against the ceiling and commonly adjacent the rear wall of the room to be cooled.
The objects of the invention are to provide a unit of th s general type which is highly eflicient, capable of bemgreadily installed and with its various components so organlzed as to be conveniently accessible for inspection and maintenance without disturbing any of the unit connections.
The invention will be readily understood from the accompanying drawings, in which:
Fig. 1 is a broken-out top plan view of the preferred form of unit;
Fig. 2 is a rear elevation;
Fig. 3 is a side elevation;
Fig. 4 is an enlarged vertical section on the line 4-4 of Fig. 1;
Fig. 5 is an enlarged horizontal section on the line 5-5 of Fig. 2; and
Fig. 6 is an enlarged view of a detail.
The coil of the unit is of semi-circular form, consisting of tubing 1 carrying radially arranged fins 2. The valve indicated by the reference 3 in Fig. l is of a special type, forming no part of the present invention. Its connectrons with the rest of the system are likewise unrelated to the present invention and are indicated schematically merely by coupling 4 and line 5, it being suflicient to note that these elements are all located within the large open space defined by the coil.
Two fans 6 are mounted at the rear of the unit and serve to draw air into the unit and discharge it radially outwardly through the coil fins.
The unit is designed for ready suspension from the ceiling of the space to be cooled and, to that end, is provided with two main hangers consisting of a channel member 7 extending across the diameter of the coil and channel member 8 extending radially of the coil. The protruding ends of channel member 7 are slotted, as at 9, so that the unit can be slid into position with the slots 9 engaged with the shanks of suitable ceiling bolts or the like. The unit is then secured in place by means of a screw passing through the protruding end 10 of channel member 8.
Immediately beneath the channel members is a cover or ceiling plate 12 which extends out over the fans and beyond them a distance sufficient to insure appropriate spacing of the rear of the unit from the wall of the space to be cooled. The fans are suspended from the channel member 8 by means of hanger straps 13, the upper ends 2,773,364 Patented Dec. 11, 1956 ice of which are secured to'the channel member by bolts 14 (Fig. 1).
Adjacent the reverse bends of the tubing at the ends of the coil, the latter is supported by end plates 15 through which the tubing passes. The tops of these plates are flanged (as at 16, Fig. 1) to abut the under side of the ceiling plate and are secured by bolts 16. The support of the coil is completed by a hanger member 17 (Fig. 4) flanged at its upper end and secured by bolts 18.
The end plates 15 are also flanged :along their inner edges (as at 20, Fig. 5) and bolted to these flanges are the end plates 21 of an open box structure. The wall 22 of this structure, which serves as a closure for the rear of the unit, incorporates openings 23 which constitute the air inlets to the fans. The top wall 24 of this closure structure (Fig. 1) abuts the under side of the ceiling plate and is secured by bolts 14.
The end plates 15 are also flanged along their outer edges (as at 28, Fig. 5) and to these flanges are bolted hanger members 29. The lower ends of these hanger members are outwardly elf-set (Fig. 6) and the off-set portion 30 of each hanger member is formed with an inwardly projecting shelf or platform 31.
Welded or otherwise secured to the hanger members 29 are downwardly and rearwardly projecting straps 35; and to the lower ends of these straps is secured a drain pan 36 having an outlet 37. This pan extends across the full width of the unit beneath the protruding coil bends, the top of its sloping rear wall terminating below and adjacent the platforms 31.
A combination drip and closure pan 328 extends beneath the entire coil and is mounted for ready removal to afford convenient access to the expansion valve, the suction and liquid line couplings and to the fan motors. As will be seen (Fig. 3) this pan 38 is designed to slide in over and seat on the platforms 31 with its rear edge overlapping the drain pan 36. The front of pan 38 is supported and secured by a wing bolt 39 engaging hanger member 17 (Fig. 4). Thus pan 38 can be readily removed for inspection or repair of any of the components mounted within the space enclosed by the coil and without disturbing the drain pan 36 or its outlet 37 which, of course, can be permanently connected to an appropriate drain line.
In the light of the foregoing description of the preferred embodiment of the invention, the following is claimed:
1. In a ceiling-mounted cooler unit of generally semicircular shape incorporating a coil located around the curved periphery of the unit, the combination of a ceiling plate; coil suspension means depending therefrom and supporting the coil at each of its ends; coil hanger means depending from the ceiling plate intermediate the ends of the coil; a fixed drain pan depending from the coil suspension means and extending across the diameter of the unit beneath the coil ends; a drip-closure plate extending beneath the coil and the space enclosed by it, with its rearward edge above and overlapping the forward edge of the drain pan; means associated with the coil suspension means for slidably supporting the rear of the dripclosure plate; and means for removably securing the for ward edge of the said drip-closure plate to the coil hanger means.
2. In a ceiling-mounted cooler unit of generally semicircular shape incorporating a coil located around the curved periphery of the unit, the combination of a ceiling plate; a fixed drain pan supported from the ceiling plate and extending across the diameter of the coil beneath the ends only thereof; a platform member at each end of the diameter of the coil suspended from the ceiling plate and projecting inwardly above the drain pan; a dripclosure plate extending beneath the coil and the space enclosed by it and slidably supported on the platform members With its rear edge above and overlapping the forward edge of the fixed drain pan; and removable means for suspending the front of the drip-closure plate from the ceiling plate.
