Description

    BACKGROUND
  • 1. Field
  • This disclosure relates to a heating, ventilating and air conditioning (HVAC) system for a vehicle and more particularly to a HVAC system for a hybrid vehicle, the HVAC system including at least one thermoelectric device for providing supplemental heating and cooling for air supplied to a passenger compartment of the vehicle.
  • 2. Description of Related Art
  • A passenger compartment of a vehicle is typically heated and cooled by a heating, ventilating, and air conditioning (HVAC) system. The HVAC system directs a flow of air through a heat exchanger to heat or cool the air prior to flowing into the passenger compartment. In the heat exchanger, energy is transferred between the air and a coolant such as a water-glycol coolant, for example. The air is normally supplied from ambient air or a mixture of air re-circulated from the passenger compartment and ambient air. Energy for heating and cooling of the passenger compartment of the vehicle is typically supplied from a fuel fed engine such as an internal combustion engine, for example.
  • In a hybrid vehicle, both a fuel fed engine and an electric motor are used to power a drive system for the vehicle. Thus, at times the fuel fed engine may be operating, the electric motor may be operating, and both the fuel fed engine and the electric motor may be operating. Therefore, the HVAC system in the hybrid vehicle must be capable of heating and cooling air during each of these operating modes. Examples of such systems are shown and described in commonly owned U.S. patent application Ser. No. 11/101,871 filed Apr. 8, 2005, hereby incorporated herein by reference in its entirety, and U.S. patent application Ser. No. 11/184,447 filed Jul. 19, 2005, hereby incorporated herein by reference in its entirety. If the fuel fed engine must be operating in order to operate the HVAC system in the hybrid vehicle, an efficiency thereof is reduced.

  • The following detailed description and appended drawings describe and illustrate various exemplary embodiments of the invention. The description and drawings serve to enable one skilled in the art to make and use the invention, and are not intended to limit the scope of the invention in any manner. In respect of the methods disclosed, the steps presented are exemplary in nature, and thus, the order of the steps is not necessary or critical.
  • FIG. 1 shows a heating ventilating, and air conditioning (HVAC) system 10 for supplying conditioned air to a passenger compartment of a vehicle according to an embodiment of the invention. The system 10 includes a first fluid circuit 12 and a second fluid circuit 14. In the embodiment shown, the first circuit 12 communicates with components of an electric side of a hybrid vehicle (not shown) and the second circuit 14 communicates with components of a fuel fed side of the hybrid vehicle. As used herein, electric side is meant to include components relating to an electric motor for powering the hybrid vehicle such as a battery compartment, for example. Fuel fed side is meant to include components relating to a fuel fed engine for powering the hybrid vehicle such as an internal combustion engine, for example. A first fluid (not shown) is circulated in the first circuit 12 and the second circuit 14 and can be any conventional fluid such as air or a coolant such as a water-glycol coolant, for example.
  • The first circuit 12 includes a first conduit 16 for conveying the first fluid through the first circuit 12. A pump 18 is disposed in the first conduit 16 to circulate the first fluid therethrough. A pump as used herein is meant to include any conventional pump such as a centrifugal pump, for example, a fan, and the like. The first conduit 16 includes a heat exchanger 20 disposed therein. The heat exchanger 20 can be any conventional heat exchanger such as a low temperature core, for example. The first fluid is also circulated through a battery compartment or other source of heat 22 from the electric side of the hybrid vehicle to remove heat therefrom. In the embodiment shown, the battery compartment 22 is disposed in parallel with the heat exchanger 20. However, it is understood that other configurations can be used as desired such as in series or a separate conduit, for example. A flow valve 24 and a diverter valve 26 are also disposed in the first conduit 16. It is understood that more or fewer valves may be used as desired to control flow of the first fluid through the first conduit 16. The flow valve 24 can be any conventional type such as a gate valve, a ball valve, a flap type valve, and the like, for example. The diverter valve 26 can be any conventional diverter valve such as a three way valve used to selectively permit flow between conduit branches, for example.
  • Crossover conduits 28, 30 are provided between the first circuit 12 and the second circuit 14. Flow valves 32, 34 are provided in respective crossover conduits 28, 30 to selectively permit flow of the first fluid therethrough. A pump 36 is also provided in the crossover conduit 28 to assist with circulation of the first fluid, if necessary.
  • A second conduit 38 is included in the second circuit 14. The second conduit 38 is in fluid communication with an engine 40 of the hybrid vehicle to circulate the first fluid therethrough and remove heat therefrom. A heat exchanger 42 is disposed in the second conduit 38 downstream of the engine 40. The heat exchanger 42 can be any conventional heat exchanger such as a radiator for the vehicle, for example. A first bypass conduit 44 is provided to permit bypassing of the heat exchanger 42 and a second bypass conduit 46 is provided to create a recirculation circuit. A diverter valve 48 selectively permits flow between the heat exchanger 42 and the first bypass conduit 44. Selective flow for the second bypass conduit 46 is facilitated by a diverter valve 50. It is understood that more or fewer valves may be used as desired to control flow of the first fluid through the second conduit 38. A pump 52 is disposed in the second conduit 38 to circulate the first fluid therethrough.
  • A first thermoelectric device (TED) 54 is disposed adjacent the first conduit 16 and between the crossover conduits 28, 30. The first TED 54 includes a first heat transfer surface 55 and a second heat transfer surface 56. The first heat transfer surface 55 is in thermal communication with the first conduit 16 of the first circuit 12. The first TED 54 is in electrical communication with a control system (not shown). The control system controls an electric current sent to the first TED 54. When the current is delivered in one direction, one of the first heat transfer surface 55 and the second heat transfer surface 56 generates thermal energy or heat and the other of the first heat transfer surface 55 and the second heat transfer surface 56 absorbs thermal energy or heat. When the current is reversed, the one of the first heat transfer surface 55 and the second heat transfer surface 56 which was generating heat now absorbs heat and the other of the first heat transfer surface 55 and the second heat transfer surface 56 now generates heat. Additionally, when the current is increased, a heating and cooling capacity of the TED is increased. Likewise, when the current is decreased, the heating and cooling capacity of the TED is decreased.
  • The TED 54 may be any conventional device such as: those produced by Marlow Industries, Inc. of Dallas, Tex.; the thermoelectric systems described in U.S. Pat. No. 6,539,725 to Bell; a quantum tunneling converter; a Peltier device; a thermoionic module; a magneto caloric module; an acoustic heating mechanism; a solid state heat pumping device; and the like; for example; or any combination of the devices listed above. Although a single thermoelectric device is shown, it is understood that additional thermoelectric devices can be used, as desired.
  • A third conduit 57 is in thermal communication with the second heat transfer surface 56 of the first TED 54. The third conduit 57 conveys a second fluid (not shown). The second fluid can be any conventional fluid such as air or a coolant such as a water-glycol coolant, for example. A pump 58 is disposed in the third conduit 57 to circulate the second fluid therethrough.
  • An air conduit 60 in fluid communication with a source of air (not shown) is provided to supply the conditioned air to the passenger compartment of the vehicle. The air conduit 60 includes a first heat exchanger 62, a second heat exchanger 64, and a third heat exchanger 66 disposed therein. The heat exchangers 62, 64, 66 can be any conventional type of heat exchanger.
  • The first heat exchanger 62 and the third heat exchanger 66 are in fluid communication with the second circuit 14. A diverter valve 68 is disposed in a supply side of the second conduit 38 to selectively control flow of the first fluid to the first heat exchanger 62 and the third heat exchanger 66. A diverter valve 70 is disposed in the second conduit 38 on a return side thereof to selectively control flow of the first fluid from the first heat exchanger 62 and the third heat exchanger 66.
  • The second heat exchanger 64 is in fluid communication with the third conduit 57. The third conduit 57 circulates the second fluid between the first TED 54 and the second heat exchanger 64.
  • In operation, the system 10 conditions the air flowing from the source of air for supply of the conditioned air to the passenger compartment of the vehicle. A flow direction of the air from the source of air is indicated by the arrow in the air conduit 60. The system 10 can operate in a heating mode, a demisting mode, and a cooling mode.
  • In a first heating mode where the engine 40 is operating and the electric motor is not operating, the first heat exchanger 62 and the second heat exchanger 64 transfer heat into the air stream, and the third heat exchanger 66 is idle. Thus, the diverter valves 68, 70 are positioned to militate against flow of the first fluid to the third heat exchanger 66 and permit flow to the first heat exchanger 62. The pump 52 of the second circuit 14 is operating to circulate the first fluid through the second conduit 38. Heat is transferred into the first fluid by the engine 40.
  • The diverter valve 48 is positioned to militate against flow through the heat exchanger 42 and permit flow through the first bypass conduit 44. Thus, heat is not removed from the first fluid in the heat exchanger 42 and the first fluid flows through the first bypass conduit 44. The diverter valve 50 is in a position to militate against flow of the first fluid through the second bypass conduit 46. Therefore, the first fluid flows through the second conduit 38 to the first heat exchanger 62 where heat is transferred from the first fluid to the air flowing in the air conduit 60.
  • The pump 18 of the first circuit 12 is not operating to circulate the first fluid through the first conduit 16. In order to supply the first fluid to the first TED 54, the pump 36 is operating and the valves 32, 34 of the crossover conduits 28, 30 are open to permit flow therethrough. A portion of the flow of the first fluid in the second conduit 38 is directed through the crossover conduit 28 and into thermal communication with the first heat transfer surface 55 of the first TED 54. The controller causes the current to the first TED 54 to flow to cause the first heat transfer surface 55 to absorb heat and remove heat from the first fluid. The first fluid then flows through the crossover conduit 30 to re-enter the second conduit 38 and flow to the first heat exchanger 62.
  • The pump 58 is operating to circulate the second fluid through the third conduit 57. The second fluid is in thermal communication with the second heat transfer surface 56 of the first TED 54. The second heat transfer surface 56 generates heat which is transferred to the second fluid. Thus, the second fluid flows to the second heat exchanger 64 where heat is transferred from the second fluid to the air flowing in the air conduit 60. Therefore, heated air is delivered to the passenger compartment of the vehicle from the first heat exchanger 62 and the second heat exchanger 64. It is understood that this mode can be used with only the first heat exchanger 62 transferring heat into the air stream and the second heat exchanger 64 idle.
  • In a second heating mode where the engine 40 is operating and the electric motor is operating, the first heat exchanger 62 and the second heat exchanger 64 transfer heat into the air stream, and the third heat exchanger 66 is idle. Thus, the diverter valves 68, 70 are positioned to militate against flow of the first fluid to the third heat exchanger 66 and permit flow to the first heat exchanger 62. The pump 52 of the second circuit 14 is operating to circulate the first fluid through the second conduit 38. Heat is transferred into the first fluid by the engine 40.
  • The diverter valve 48 is positioned to militate against flow through the heat exchanger 42 and permit flow through the first bypass conduit 44. Thus, heat is not removed from the first fluid in the heat exchanger 42 and the first fluid flows through the first bypass conduit 44. The diverter valve 50 is in a position to militate against flow of the first fluid through the second bypass conduit 46. Therefore, the first fluid flows through the second conduit 38 to the first heat exchanger 62 where heat is transferred from the first fluid to the air flowing in the air conduit 60.
  • The pump 18 of the first circuit 12 is operating to circulate the first fluid through the first conduit 16 to supply the first fluid to the first TED 54. The pump 36 is not operating and the valves 32, 34 of the crossover conduits 28, 30 are closed to militate against flow therethrough. The first fluid flows through the battery compartment 22 where heat is transferred into the first fluid, then through the first conduit 16, and into thermal communication with the first heat transfer surface 55 of the first TED 54. The diverter valve 26 is positioned to militate against flow through the heat exchanger 20 and permit flow to the battery compartment 22. Thus, heat is not removed from the first fluid in the heat exchanger 20. The controller causes the current to the first TED 54 to flow to cause the first heat transfer surface 55 to absorb heat and remove heat from the first fluid. The first fluid then returns to the pump 18 for recirculation.
  • The pump 58 is operating to circulate the second fluid through the third conduit 57. The second fluid is in thermal communication with the second heat transfer surface 56 of the first TED 54. The second heat transfer surface 56 generates heat which is transferred to the second fluid. Thus, the second fluid flows to the second heat exchanger 64 where heat is transferred from the second fluid to the air flowing in the air conduit 60. Therefore, heated air is delivered to the passenger compartment of the vehicle from the first heat exchanger 62 and the second heat exchanger 64.
  • In a third heating mode where the engine 40 is not operating and the electric motor is operating, the second heat exchanger 64 transfers heat into the air stream, and the first heat exchanger 62 and the third heat exchanger 66 are idle. Initially, it is presumed that the engine 40 was previously running and requires cooling. The pump 52 of the second circuit 14 is operating to circulate the first fluid through the second conduit 38. Heat is transferred into the first fluid by the engine 40.
  • The diverter valve 48 is positioned to militate against flow through the first bypass conduit 44 and permit flow through the heat exchanger 42. Thus, heat is removed from the first fluid in the heat exchanger 42. The diverter valve 50 is in a position to permit flow of the first fluid through the second bypass conduit 46 and militate against flow through the second conduit 38 to the first heat exchanger 62 and the third heat exchanger 66. Once the engine 40 has sufficiently cooled, the pump 52 can be switched to the off position until the engine 40 requires additional cooling.
  • The pump 18 of the first circuit 12 is operating to circulate the first fluid through the first conduit 16 to supply the first fluid to the first TED 54. The pump 36 is not operating and the valves 32, 34 of the crossover conduits 28, 30 are closed to militate against flow therethrough. The first fluid flows through the battery compartment 22 where heat is transferred into the first fluid, then through the first conduit 16, and into thermal communication with the first heat transfer surface 55 of the first TED 54. The diverter valve 26 is positioned to militate against flow through the heat exchanger 20 and permit flow to the battery compartment 22. Thus, heat is not removed from the first fluid in the heat exchanger 20. The controller causes the current to the first TED 54 to flow to cause the first heat transfer surface 55 to absorb heat and remove heat from the first fluid. The first fluid then returns to the pump 18 for recirculation.
  • The pump 58 is operating to circulate the second fluid through the third conduit 57. The second fluid is in thermal communication with the second heat transfer surface 56 of the first TED 54. The second heat transfer surface 56 generates heat which is transferred to the second fluid. Thus, the second fluid flows to the second heat exchanger 64 where heat is transferred from the second fluid to the air flowing in the air conduit 60. Therefore, heated air is delivered to the passenger compartment of the vehicle from the second heat exchanger 64. It is also understood that this mode can be used when both the engine 40 and the electric motor are operating, but where the amount heat required to be delivered to the passenger compartment of the vehicle is low.
  • In a demisting mode, the engine 40 is operating and the electric motor is operating. The first heat exchanger 62 is idle, the second heat exchanger 64 removes heat from the air stream, and the third heat exchanger 66 transfers heat into the air stream. It is understood that the engine 40 may have also been previously running and has residual heat stored therein. The diverter valves 68, 70 are positioned to militate against flow of the first fluid to the first heat exchanger 62 and permit flow to the third heat exchanger 66. The pump 52 of the second circuit 14 is operating to circulate the first fluid through the second conduit 38. Heat is transferred into the first fluid by the engine 40.
  • The diverter valve 48 is positioned to militate against flow through the heat exchanger 42 and permit flow through the first bypass conduit 44. Thus, heat is not removed from the first fluid in the heat exchanger 42 and the first fluid flows through the first bypass conduit 44. The diverter valve 50 is in a position to militate against flow of the first fluid through the second bypass conduit 46. Therefore, the first fluid flows through the second conduit 38 to the third heat exchanger 66 where heat is transferred from the first fluid to the air flowing in the air conduit 60.
  • The pump 18 of the first circuit 12 is operating to circulate the first fluid through the first conduit 16 to supply the first fluid to the first TED 54. The pump 36 is not operating and the valves 32, 34 of the crossover conduits 28, 30 are closed to militate against flow therethrough. The diverter valve 26 is positioned to permit flow through the heat exchanger 20 and militate against flow to the battery compartment 22. Thus, heat is removed from the first fluid in the heat exchanger 20. The controller causes the current to the first TED 54 to flow to cause the first heat transfer surface 55 to generate heat which is absorbed by the first fluid. The first fluid then returns to the pump 18 for recirculation.
  • The pump 58 is operating to circulate the second fluid through the third conduit 57. The second fluid is in thermal communication with the second heat transfer surface 56 of the first TED 54. The second heat transfer surface 56 removes heat from the second fluid. Thus, the second fluid flows to the second heat exchanger 64 where heat is transferred from the air flowing in the air conduit 60 to the second fluid. Therefore, air is cooled in the second heat exchanger 64, heated by the third heat exchanger 66, and delivered to the passenger compartment of the vehicle for demisting. By initially cooling the air, moisture is caused to be removed from the air by condensation.
  • In a cooling mode, where the engine 40 is not operating and the electric motor is operating, the second heat exchanger 64 removes heat from the air stream, and the first heat exchanger 62 and the third heat exchanger 66 are idle. Initially, it is presumed that the engine 40 was previously running and requires cooling. The pump 52 of the second circuit 14 is operating to circulate the first fluid through the second conduit 38. Heat is transferred into the first fluid by the engine 40.
  • The diverter valve 48 is positioned to militate against flow through the first bypass conduit 44 and permit flow through the heat exchanger 42. Thus, heat is removed from the first fluid in the heat exchanger 42. The diverter valve 50 is in a position to permit flow of the first fluid through the second bypass conduit 46 and militate against flow through the second conduit 38 to the first heat exchanger 62 and the third heat exchanger 66. Once the engine 40 has sufficiently cooled, the pump 52 can be switched to the off position until the engine 40 requires additional cooling.
  • The pump 18 of the first circuit 12 is operating to circulate the first fluid through the first conduit 16 to supply the first fluid to the first TED 54. The pump 36 is not operating and the valves 32, 34 of the crossover conduits 28, 30 are closed to militate against flow therethrough. The diverter valve 26 is positioned to permit flow through the heat exchanger 20 and militate against flow to the battery compartment 22. Thus, heat is removed from the first fluid in the heat exchanger 20. The controller causes the current to the first TED 54 to flow to cause the first heat transfer surface 55 to generate heat which is absorbed by the first fluid. The first fluid then returns to the pump 18 for recirculation.
  • The pump 58 is operating to circulate the second fluid through the third conduit 57. The second fluid is in thermal communication with the second heat transfer surface 56 of the first TED 54. The second heat transfer surface 56 removes heat from the second fluid.

The second TED 102 includes a first heat transfer surface 104 and a second heat transfer surface 106. The first heat transfer surface 104 is in thermal communication with the first conduit 16 of the first circuit 12. The second TED 102 is in electrical communication with a control system (not shown). The control system controls an electric current sent to the second TED 102 in the same way as described for the first TED 54. The second thermoelectric device 102 may be any conventional device such as those listed for the first TED 54.

A portion of the flow of the first fluid in the second conduit 38 is directed through the crossover conduit 28 and into thermal communication with the first heat transfer surface 55 of the first TED 54 and the first heat transfer surface 104 of the second TED 102. The controller causes the current to the first TED 54 and the second TED 102 to flow to cause the first heat transfer surface 55 and the first heat transfer surface 104 to absorb heat and remove heat from the first fluid.
