Abstract
A unit ventilator is disclosed wherein, in order to facilitate service and repair of the ventilator and/or its component parts, such parts are mounted for ease of access and of detachment from, or assembly to, the system. Elemental system parts, such as the blower assembly, the heat transfer coil assembly, the condensate discharge pan and the air filters are designed and arranged so as to be assembled and/or disassembled from the system rapidly and with minimum use of tools.
Claims12
A unit ventilator comprising:
- a cabinet forming a fixed enclosure and having openings forming an inlet for input air and an outlet for discharge air spaced from said inlet;
- framing structure for the cabinet including a top plate, a base plate, a pair of oppositely spaced end plates upstanding from said base, and a removable front panel;
- a fan assembly including a motorboard having at least one fan and drive means therefore suspended from said motorboard;
- a coil assembly including a plurality of coil tubes, a pair of tube sheets at oppositely spaced ends of said coil tubes and being operative to connect said coil tubes for circulation of a heat transfer fluid therethrough;
- flange means disposed on said end plates including a first set of flanges operative to mountingly receive cooperating flanges on said coil assembly for detachably supporting said coil assembly on said end plates, and a second set of flanges on said end plates to mountingly receive said motor board for detachably supporting said fan assembly on said end plates;
- and
- means for circulating input air through said fan assembly and, thence, in heat transfer relation with respect to said coil tubes before discharge from said outlet.

- framing structure for the cabinet including a top plate, a base plate, a pair of oppositely spaced end plates upstanding from said base plate, and a removable front panel, said end plates each being spaced inwardly from respective ends of said cabinet;
- a fan assembly including a motorboard, at least one fan and drive means therefor suspended from said motorboard;
- a coil assembly including a plurality of coil tubes, a pair of tube sheets at oppositely spaced ends of said coil tubes and being operative to connect said coil tubes for circulation of a heat transfer fluid therethrough;
- flange means disposed on said end plates including a first set of flanges containing flanges being offset from an upper edge of said end plates and operative to mountingly receive cooperating flanges on said coil assembly for detachably supporting said coil assembly on said end plates, and a second set of flanges on said end plates containing flanges spaced below said first set of flanges and being offset from said end plates intermediate the height thereof to mountingly receive said motor board for detachably supporting said fan assembly on said end plates;
- and
- means for circulating input air through said fan assembly and, thence, in heat transfer relation with respect to said coil tubes before discharge from said outlet.
