Definitions

  • the present invention relates to a device for cooling the compressor of a thermal compression machine and more particularly to a means of starting this device of the thermo-siphon type.
  • a conventional compression thermal machine comprises in series a compressor, a condenser, a pressure reducer and an evaporator, connected together by tubes to form a closed circuit traversed by a fluid.
  • the fluid undergoes variations in pressure and temperature throughout this closed circuit. Compressed by the compressor, it liquifies inside the condenser, then, after passing through the regulator, it evaporates in the evaporator.
  • a compression thermal machine can operate as a refrigerator or a heat pump.
  • the fluid evaporates in the evaporator providing cold to the environment which surrounds it, and becomes liquid in the condenser by borrowing cold from the environment which surrounds it.
  • the fluid evaporates in the evaporator by borrowing heat from the medium which surrounds it and is liquidated in the condenser by restoring heat to the medium which surrounds it.
  • this cooling circuit is constituted by a thermo-siphon comprising an evaporator immersed in the oil of the compressor in thermal contact with the casing thereof, and a condenser , connected together by two tubes to form a closed circuit traversed by a fluid.
  • the fluid When the thermo-siphon is primed, the fluid, by evaporating in the evaporator, borrows heat from the oil of the compressor, which is the desired goal, and returns it to the external medium by liquefying in the condenser .
  • the present invention relates to a priming device allowing the immediate priming of the thermo-siphon as soon as the installation is put into service.
  • thermosiphon type which comprises an evaporator immersed in the oil of the compressor and a condenser connected to the evaporator by an ascending tube and a descending tube, being characterized in that a portion at less of the ascending tube is subjected to the action of an auxiliary heat source distinct from the compressor casing and allowing the instantaneous priming of the thermosiphon as soon as the compressor starts up.
  • the auxiliary heat source is at least a portion of the compressor discharge tube.
  • a portion of the rising tube of the cooling device is placed in close contact with a portion of the discharge tube of the compressor.
  • a conventional compression thermal machine comprising in series a compressor 1, a condenser 2, a regulator 3, and an evaporator 4, connected together by tubes to form a closed circuit traversed by a fluid.
  • the compressor 1 is connected to the condenser 2 by its delivery tube 5 and to the evaporator 4 by its suction tube 6.
  • This drawing also shows a compressor cooling circuit comprising an evaporator 7 immersed in the oil contained in the compressor casing (the oil being shown in dotted lines), and a condenser 8, connected together by an ascending tube. 9 and by a downward tube 10, to form a thermo-siphon also traversed by a fluid.
  • the ascending tube 9 is connected to the upper part of the condenser 8, and the descending tube 10 to its lower part. In this way the circuit of the cooling and asymmetrical fluid and the fluid tends to circulate naturally under the effect of the thermo-siphon produced by density variations due to temperature variations along its path.
  • thermo-siphon tends to initiate with a significant delay in the starting time of the compressor.
  • this compressor operates cyclically, under the control, for example, of the refrigerator thermostat, the thermo-siphon barely has time to start before the compressor stops. It then operates nominally for only a few moments and then stops in turn. As a result, the cooling it provides is irregular and poor.
  • the piping 5 in which the hot gases leaving the compressor circulate is brought into intimate contact over a certain length, with the ascending piping 9 in which the cooling fluid heated by the compressor circulates. 'it cools.
  • the pipe 5 therefore strongly heats the pipe 9 and therefore the coolant. Under this effect it tends to rise immediately and forcefully towards the top of the condenser 8 because care has been taken to place the path of the pipe 9 above the compressor 1 and with a positive slope.
  • a frank and immediate priming of the thermo-siphon is obtained. This can then properly cool the compressor as soon as it is started.
