11 Claims. (01. 62-115) This invention relates to refrigeration and more particularly to a condensing unit for refrigerating apparatus of the compression type.
It is an object of the invention to provide a condensing unit in which a compressor, a motor, a condenser, and a fan are compactly arranged and mounted on a novel base so as to provide efficient air cooling while occupying a minimum amount of floor space.
Other objects and advantages of the invention will appear in the following description in connection with the accompanying drawing of which:
Fig. 1 is a side elevation of a condensing unit embodying the invention, part of the base being shown broken away to reveal parts of the apparatus therein;
Fig. 2 is a sectional View on line 2-2 of Fig. 1;
Fig. 3 is a sectional view on line 3-3 of Fig. 1.
The illustrated condensing unit consists of a compressor If], an electric motor H for drivin the compressor, an air cooled condenser l2, a fan 13, and a receiver [4. The compressor It is of a reciprocating type, although any type of compressor may be used. The crank shaft of compressor i is indicated by the reference character IS in Fig. 1. The intake connection of compressor if] is shown as a conduit IS. The compressor has a discharge conduit ll adapted to be connected to the lower end [8 of condenser 12 by a conduit, not shown. The upper end 18 of condenser I2 is adapted to be connected to an inlet l9 of receiver 14. Receiver I4 has an outlet 20 adapted to be connected to th inlet side of an evaporator or low side unit, not shown. The intake connection 16 of compressor 19 is adapted to be connected to the vapor line of the evaporator.
A base for supporting said parts of the condensing unit includes a shell 22 of sheet metal bent into a substantially rectangular U-shape or channel form to provide a floor plate 23 and a pair of upright side walls 24. The upper edges of the side walls 24 are bent inward along part of the length to form flanges 25. A plate 21 is supported on and connected to th flanges 25. The compressor Ill is mounted on the upper side of plate 21. The electric motor H is mounted on the under side of plate 21. These parts are secured to the plate by bolts 28 and 29. The plate 21 is secured to the flanges 25 by bolts 35 which pass through rubber cushions 34 between the plate 21 and flanges 25. In this manner, the compressor I0 and motor II are resiliently supported as a unit. The motor and compressor are connected by a belt 40 which passes around the compressor flywheel 39 on shaft l5, and a motor pulley 31 on the motor shaft 38.
Condenser l2 comprises tubing provided with fins for air cooling. The condenser is assembled on a pair of upright plates 45. The plates 45 are flanged outward on their upper and lower edges. The condenser 12 is mounted vertically in one end of the base 22. At this end of base 22, the sections 42 of the side walls 24 are higher and provided with inward flanges 43. The upper flanges 48 of the condenser plates are connected to the base flange 43 by bolts 50. These bolts also hold a plate 5! across the top of the'condenser. The receiver 14 is mounted on top of plate 5|.
Adjacent condenser 12 a fan [3 is mounted on the end of motor shaft 38 beyond the motor pulley 31. In operation, when'motor I5 is operating to drive compressor Ill, fan i3- blows air through the channel 26 in the base 22 to cause a forced draft of air for cooling condenser. l2.
