Definitions

  • the invention relates to a working according to a regenerative gas cycle process Heating and cooling machine with at least two pistons, the minimum three process rooms, each with at least one heat exchanger and at least one regenerator connected in series with this separate from each other.
  • the invention has for its object one after a regenerative gas cycle process to create working heating and cooling machine in which the Risk of freezing of the cold heat exchanger with design and control technology is simply eliminated in an energetically meaningful manner.
  • the solution to this problem by the invention is characterized in that that at least one of the cold process room assigned Regenerators to change the cold heat exchange circuit amount of heat transferred between process gas and environment with at least a bypass containing a control valve is provided.
  • the inventive formation of a bypass to at least one of the regenerators assigned to the cold heat exchanger is activated the bypass valve of icing on the air heat exchanger is limited in time opened so that the process gas in this bypassed bypass Regenerator no heat is removed and in this way the in the machine arranged cold heat exchangers through the from the warm process room amount of heat coming to a temperature above freezing is brought, with which the air heat exchanger is de-iced at the same time. Also in the event of a failure of the circulation pump in the one belonging to the cold heat exchanger In this way, the cycle becomes active even when the machine is running freezing of the cold heat exchanger avoided.
  • the bypass line is in Formed a through opening in the regenerator, the two Ends are closed during normal operation of the machine. This results in a dead space-free design of this regenerator.
  • bypass line is passed through closed a plunger, which is countered by an electromagnet Force of a return spring is movable.
  • the heating and cooling machine shown schematically in Figure 1 includes a pressure-tight housing 1, in which a hot piston 2 and a cold piston 3 are arranged linearly movable.
  • the hot piston 2 limits a hot working volume 4, to which heat is supplied, for example by a gas-heated one Combustion chamber 5.
  • the cold piston 3 limits a cold working volume 6.
  • Both pistons 2 and 3 limit a warm working volume 7.
  • a gear 8 is provided, which is connected to the cold via a hollow piston rod 9 Piston 3 and another piston rod 10 with the hot piston 2 connected is.
  • a regenerator 11 or 12 is arranged.
  • the warm working volume 7 is also assigned a warm heat exchanger 14, which is connected in series with the regenerator 11 and as well this is flowed through by the process gas. From this warm heat exchanger 13 is heated in the closed circuit via a circulation pump 13a a heat exchanger designed as a heater 14, for example.
  • the cold working volume 6 is also in series with the regenerator 12 assigned cold heat exchanger 15 through which process gas flows, the one with an air heat exchanger 16 in a closed circuit is arranged.
  • a circulation pump 15a is located in this circuit.
  • the heating and cooling machine is the one assigned to the cold working volume 6
  • Regenerator 12 is provided with a bypass 17, in which a bypass valve 17a is arranged. In normal operation, this bypass valve 17a is closed, see above that the bypass 17 has no effect on the after a regenerative gas cycle process working heating and cooling machine.
  • the bypass valve is also to be eliminated if the circulation pump 15a fails 17a opened at least for a limited time.
  • the process gas is due the lower flow resistance, the regenerator 12 through the Bypass bypass 17 so that the process gas in the regenerator 12 no heat is withdrawn. Since the cold heat exchanger 15 is connected in series to the regenerator 12 is switched, the cold heat exchanger 15 by the from the warm Working volume 7 coming amount of heat at a temperature above the Freezing point brought or held.
  • FIG. 2 shows an embodiment of the regenerator 12 in one Longitudinal section.
  • the regenerator 12 stands with the cold working volume 6 of the machine via an annular channel 18 and is in series switched to the cold heat exchanger 15, part of which is also in Figure 2 is shown.
  • the part of the regenerator 12 shown in FIG. 2 is further provided with a through hole 12a through a plunger 19 is closable. In the closed position, the plunger 19 fills the through opening 12a of regenerator 12 acting as a bypass, see above that there is no dead space in the normal operation of the machine due to the bypass.
