Convertible and compact refrigeration system
View Patent ↗A refrigeration system comprises a fan and motor unit 575 having a plurality of cross-flow blower wheels 530 or air blower turbines place upon either side of a motor or unique cross flow motor. The fan and motor unit 575 may be attached to either a top plate 550 to create a side discharge or to a back plate 570 to create a top discharge. The top plate 550 comprises a plurality of top discharge vents and a front discharge plate cover 545 comprises a plurality of side discharge vents 546 . A technician in the field may configure a disclosed refrigeration system either a side or top discharge by rotating the position of the fan and motor unit.
1. A refrigeration system, convertible to top discharge or side discharge, the system comprising: a) a fan and motor unit comprising:
i. one or more cross-flow blower wheels independently attached to the motor, the cross-flow blower wheels attached to either side of the motor;
ii. a fan cover for each cross-flow blower wheel, the fan cover partially covering each cross-flow blower wheel; the fan cover having four edges, the four edges terminating on same plane defining a flow void; the fan cover rotatable to align the air flow void to either a top discharge vent or a side discharge vent, the fan cover attached to a plurality of fastening clips; the fan cover capable of being independently oriented to direct cooled air through the top discharge vent or the side discharge vent;
b) a motor housing comprising:
i. a top plate comprising top discharge vents and a plurality of fastener voids complementary to the plurality of fastening clips;
ii. a back plate attached to the top plate at an angle between 75 and 115 degrees, the back plate comprising a plurality of fastener voids complementary to the plurality of fastening clips;
c) a front discharge plate cover attached to the top plate, the front discharge plate cover comprising a plurality of side discharge vents;
d) a lower housing connected to the front discharge plate cover and the lower housing comprising a condensation pan, a liquid line U-bend, a TXV valve, a coated evaporator coil, a sensing bulb, a digital control stat, and a power head; and
e) the plurality of fastening clips of the fan and motor unit are attached to the fastener voids within the top plate of the motor housing or the front discharge plate of the motor housing.
2. The system of claim 1 wherein the plurality of fastening clips of the fan and motor unit are attached to the fastener voids of the back plate.
3. The system of claim 1 wherein the plurality of fastening clips surrounds each cross-flow blower wheel.
4. The system of claim 1 wherein the digital control stat is attached to the front discharge plate cover.
