Definitions

  • the present invention relates to refrigeration units. More particularly, the present invention relates to refrigeration units of the type which are used as air conditioners in motorcars, for example.
  • This arrangement needs not only three long hoses with at least six gastight connections, but it requires a substantial degree of assembly skill, contrary to the industrial assembling of hermetically sealed refrigeration units, for example. Therefore the assembling of standard automotive airconditioning units is not only expensive, but also less safe than it could be if the three main units were combined to only one compact unit, containing all necessary parts in itself.
  • An additional object of the present invention is to provide a structure of the rotating heat exchanger fins capable of acting as blades of a blower, so that the condensing and the evaporating parts of the all rotating system have a self-ventilating action.
  • the present invention utilizes a double action single cylinder compressor with symmetrical design of all parts, rotating around their centers of gravity. Because two different centers exist with a distance of half the stroke, a relative movement of the piston in the cylinder takes place, resulting in a compressor action. Instead of reciprocating like stat'iffy compressors, only a relative rotation around different centers will happen and therefore no counterweight and practically no balancing is needed and if any imbalance is found it may be removed like balancing a wheel of a motorcar.
  • the heat exchangers are formed to symmetrical rotational cylinders, rotating around the same center which is represented by the crankshaft.
  • an expansion device of standard design is inserted between the condenser and the evaporator.
  • the fins of the condenser are formed to blades and act as a blower wheel, which may be surrounded by a blower housing.
  • the evaporator tube spiral with its supporting helical spiral pump takes in the warmed air, cooling it and exhausting it through the inside passage of a double walled airhose, the other passage of which will conduct the warmed air from the car to the cooling unit. This prevents the cooled air from becoming warmed up by the hot air, for example in the engine compartment. Suitable insulation prevents any temperature exchange between the evaporator and the condenser.
  • additional electrical blowers may help to transport the air.
  • the operational speed may be raised and with that the refrigeration capacity enlarged, and at the same time also the heat exchanging value.
  • a rotary seal is used to secure tightness between the stationary and the rotating parts of the unit.
  • a magnetic clutch may engage the all rotating unit, directed by a thermostat.
  • FIG. 1 shows a longitudinal sectional view of a preferred embodiment of the present invention
  • FIG. 2 is a top view of FIG. 1;
  • FIG. 3 is an end view, showing primarily the blower arrangement.
  • a frame 1 has a bearing 2 on the driving side and at the opposite end a mount 3 for the stationary crankshaft 4.
  • the relief valves 18 and 19 will guide the compressed refrigerant into the concentric distributor 20 and through a notillustrated muffler on the outlet 21 out of the compressor into the concentric tube windings 22 and 23, where the gas is able to dissipate its overheat and will then enter the condenser tube 24, which is coiled around the finned body 25, the fins of which are formed as blades 26, resulting in a blower wheel which rotates within the blower housing 47 and takes in the cooling air through the duct 46, blowing it out through the other duct 48.
  • This cooling air may take place outside of the engine compartment, where the air is not yet warmed up.
  • an expansion device 27 of known design is provided, a capillary tube for example, which will transfer the refrigeration fluid to the also coiled rotating evaporator 28, where the fluid will evaporate. After passing the evaporator coil 28 the gas enters through the tube 29 into the ring-shaped distributor 30.
  • the coiled evaporator tube 28 is supported on the tubular extension 8 by spiral fins 32, which will suck in the warmed air coming out of the passenger compartment, while the outer fins 33 in the opposite direction will press the cooled air over the outside of the evaporator 28 into the inside of the double walled airhose 43.
  • the insulation tube 35 separating the evaporator chamber from the condenser part of the rotating heat exchanges, is suspended by the centering webs 36 and 37 at its cylinder front and on the opposite side by the end flange 38, which is a part of the tubular extension 8. This flange 38 has the inlets 39 for the incoming warmed air and the outlets 40 for the outgoing cooled air.
  • the rotating flange 38 separates the warmed air from the cooled air via the seals 41 and 42, while insulation 45 prevents heat exchange between any outside hot air and the double walled airhose 43 and 44.
  • this invention which has in view more compact automotive airconditioning units, comprehending the till now separated compressor, condenser and evaporator devices in form of only one unit which is self-ventilated, uses also many elements of already known design besides the described improvements to make the complete airconditioner.
  • the arrangement of the heat exchangers may be changed with regard to the air guide, for example side by side instead of the described telescopic design, if the all rotating design of the compressor, the condenser and the evaporator is maintained.
  • the self-ventilation may be assisted by additional electric blowers, controlled by thermostats.
  • a stationary crankshaft having two axially arrayed sections; a compressor casing mounted for rotation about said crankshaft coaxially therewith, said casing having a first portion surrounding one of said sections and a second portion surrounding the other of said sections and being confitgurated as a s mmetrical doubleacting cylinder elonga ed transverse y of the longitudinal axis exchange means including a condensor and an operatively associated evaporator one of which is located within the confines of the other, and a separator of thermally insulating material interposed between said evaporator and condensor; and a plurality of blades provided on said heat exchange means for effecting movement of ambient air relative to said heat exchange means in response to rotation of the latter and for heat exchange between the moving air and said fluid stream.
  • said condenser being configurated as a body of rotation and having a circumference provided with some of said blades which together constitute an impeller.
  • said evaporator being of tubular configuration and surrounding said first portion with clearance; and further comprising helical supporting web means in said clearance, supporting said evaporator on said first portion for rotation with both and operative for effecting aspiration and movement of air in one axial direction of said clearance.
  • said condenser surrounding said evaporator and defining with the same an annular space; and further comprising additional helical supporting web means in said space, supporting said condenser on said evaporator and being operative for effecting aspiration and movement of air through said space in an axial direction opposite to said one direction.
