Definitions

  • the invention relates to an air conditioning system, in particular for a motor vehicle, according to the preamble of claim 1 .
  • An air conditioning system of such type is known from DE 36 35 353, in which the air conditioning system can also be operated as a heat pump, the energy which needs to be fed to the refrigeration circuit originating from the energy losses of the motor vehicle, that is to say from the hot coolant heat energy which is otherwise discharged, without being utilized, to atmosphere, via the radiator of the motor vehicle.
  • a heat exchanger is provided which, during heating operation of the air conditioning system, serves as an evaporator for the refrigerant, the energy for evaporation of the refrigerant being taken from the hot engine refrigerant, so that the coolant is evaporated through utilization of the coolant energy.
  • An air conditioning system of such type can however be improved.
  • an air conditioning system in particular a motor vehicle air conditioning system, having a circuit
  • circuit are arranged a refrigerant compressor, a gas cooler, an inner heat exchanger, an expansion element and an evaporator, a device for reversing the flow direction of the refrigerant being provided for heat pump operation, and means being provided which deactivate the inner heat exchanger while the flow direction is reversed.
  • the refrigerant flows from the gas cooler (first heat exchanger) to the expansion element, and from the evaporator (second heat exchanger) to the refrigerant compressor, are thermally coupled by means of the inner heat exchanger.
  • the inner heat exchanger is bypassed, so that there is no thermal coupling between the refrigerant flows.
  • the entire arrangement makes possible a simply constituted heat pump without additional components in the refrigerant circuit.
  • the means which deactivate the inner heat exchanger while the flow direction is reversed preferably comprise two non-return valves which are arranged in corresponding lines provided in parallel with the inner heat exchanger.
  • the non-return valves can also be provided on or in the inner heat exchanger.
  • the device for reversing the flow direction is preferably formed by means of a suitable means of switching to a cross-over circuit of the back pressure and high pressure connections on or in the refrigerant compressor.
  • An expansion element having two antiparallel bypasses is preferably provided in the circuit. This is preferably an orifice expansion element having two flow-direction-dependent antiparallel bypasses.
  • the evaporator assumes the heating function during heat pump operation.
  • CO 2 is preferably used as the refrigerant.
  • Other refrigerants are however also possible.
  • a compressor regulator valve and a device for switching the refrigerant flow direction are preferably electrically controlled.
  • An adjustable stroke volume of the refrigerant compressor for controlling the refrigeration power, (AC operation) and the heating power of the heat pump is particularly advantageous.
  • FIG. 1 shows a schematic illustration of an air conditioning system according to the invention in AC operation, only those components relevant to this operating state being illustrated, and
  • FIG. 2 shows a schematic illustration of the air conditioning system from FIG. 1 in heat pump operation.
  • An air conditioning system 1 has a circuit 2 having a refrigerant compressor 3 , a first heat exchanger 4 which is connected downstream of said refrigerant -compressor 3 and serves as a gas cooler in AC operation, an inner heat exchanger 5 , an expansion element 7 having two antiparallel bypasses, and a second heat exchanger 8 which serves as an evaporator in AC operation.
  • Refrigerant flows clockwise through the circuit 2 in AC operation, as illustrated in FIG. 1 .
  • heat is exchanged here between refrigerant coming from the first heat exchanger 4 and refrigerant coming from the second heat exchanger 8 .
  • the inner heat exchanger 4 is deactivated on account of non-return valves 9 arranged in corresponding lines.
  • flows passes through the circuit 2 counter-clockwise.
  • the first heat exchanger 4 assumes the function of an evaporator and the second heat exchanger 8 acts as an additional heater.
  • the expansion element 7 embodied by means of two antiparallel bypasses can be used without external control measures in both operating modes, that is to say in AC operation and in heat pump operation.
