- Temperature control systems such as vehicle heaters and air conditioners have improved in recent years. Most common in the transportation industry today are compressor based air-conditioning units that use power from the engine to drive the compressor. When the engine is idling, running the A/C unit may require the engine to idle at higher RPM's. Idling the engine at higher RPM's, however, causes an increase in noise, fuel consumption, and pollution. Furthermore, high fuel prices make it desirable to turn the vehicle's engine off when the vehicle is parked for extended periods of time. In order to run a compressor-based A/C unit while the engine is off, power from the vehicle's battery power is generally needed. Such battery use can, however, only be continued for a short period of time before the battery is completely emptied.
- Federal and local regulations have exacerbated the problems associated with the above-mentioned issues. For environmental reasons, vehicles parked at truck stops are often only allowed to idle for a limited period of time. In certain instances, this time is as little as only a few minutes. Unfortunately, vehicle drivers are often required to stay overnight at truck stops or the likes for a myriad of reasons. One reason may be that the driver reaches the maximum number of operating hours allowed by company policy or other regulations. Another reason may be that the driver becomes too tired to continue driving safely.
- It is well known that many of commercial drivers choose to sleep in their respective vehicles while parked at truck stops or other rest areas. Whether during the day or overnight, the temperature outside may be too hot to comfortably sleep without air conditioning. In those situations, it would be desirable to have a vehicle air-conditioning unit capable of cooling an interior of the vehicle without running the vehicle's engine. It is also critical that any better power consumption will not drain the vehicle's battery below the minimum level required to start the vehicle the next day.
- It should also be noted that the temperature outside the vehicle may also be too low for the driver to sleep comfortably in the vehicle without having a heater running. In those situations, it would be desirable to have a heating unit capable of heating an interior of the vehicle without requiring the vehicle's engine to be running. It would also be desirable for the heating unit to heat the interior of the vehicle in such a way that the vehicle's battery is not drained below the minimum level required to start the vehicle.

- Referring now to the drawings,
FIG. 1 is a block diagram of anair comfort system 100 adapted to cool the inside of an enclosure, such as, for example, a cabin and/or sleeping space of a tractor-trailer according to one embodiment. Theair comfort system 100 generally comprisesair inlet 102,pre-cool unit 104, filter andevaporator 106, water and pump 108,controller 110,heat transfer assembly 112,TEC exhaust 114,exhaust air outlet 122,variable speed fan 116, andair outlet 123. As discussed in more detail below,heat transfer assembly 112 in one embodiment may comprise the components shown inFIG. 3 , including a plurality offins 306, a plurality ofthermoelectric coolers 302, and a plurality offlow tunnels 304. - Referring again to
FIG. 1 ,air comfort system 100 is adapted to receive air viaair inlet 102. The air passing throughair inlet 102 may be air from either inside or outside the enclosure or a combination of the two. As will be explained in more detail below, the air may pass through apre-cool unit 104 before going to afilter 106. Furthermore, as will be understood by one skilled in the art, the order in which the air is passed through the various modules of theair comfort system 100 may be varied while still accomplishing the goal of conditioning the air by either cooling or heating the air. - As shown in
FIG. 1 , theair comfort system 100 includes avariable speed fan 116 to pull air through thesystem 100. However, it is also contemplated that one or morevariable speed fans 116 may be disposed at various locations in or around thesystem 100 in order to move the air. The variable-speed fans 116 may be utilized to either push the air through thesystem 100, pull the air through thesystem 100, or a combination of pushing and pulling the air through thesystem 100. In the embodiment shown, the air passes through amodule 106 comprising a combination filter and evaporator before passing to aheat transfer assembly 112. In various embodiments, themodule 106 may be only a filter, only an evaporator, both or may be neither. The filter ofmodule 106 may help remove dirt, debris, allergens, and/or other contaminants from the air passing therethrough. The evaporator ofmodule 106 may be a mist membrane that humidifies the air. In the embodiment shown, apump 108 is used to deliver water from an H2O or other fluid reservoir to the mist membrane to increase the humidity of the air passing therethrough. In addition, a humidity sensor may be utilized to monitor the humidity of the air either before the mist membrane, after the mist membrane, or both. A determination may then be made as to whether the humidity of the air should be increased and/or whether evaporative cooling may be utilized to increase the efficiency of cooling the ambient air. - In the embodiment shown in
FIG. 1 , after the air passes through the filter andevaporator module 106, the air is then passed through theheat transfer assembly 112. As will be explained in more detail below, theheat transfer assembly 112 may include a plurality of flow tunnels with multiple fins on both an inside and an outside section thereof. The inside fins may produce a controlled temperature flow that is passed through theair outlet 123 via thevariable speed fan 116. The outside fins may pass the opposite thermal flow of air to aTEC exhaust 114 to theexhaust air 122. In some embodiments, the system may produce the controlled temperature by either heating an ambient temperature or cooling an ambient temperature. - In various embodiments, a plurality of sensors may be utilized to monitor various aspects of the
system 100 and/or the environment. For example, in various embodiments, thesystem 100 may have acontroller 110 containing one or more processors adapted to receive a plurality of signals from one or more of the plurality of sensors. The sensors may be disposed so as to monitor the temperature inside the enclosed space, the temperature outside the enclosed space, the humidity of the air, the battery power, and/or any other aspect that may need to be monitored to ensure a comfortable environment inside the enclosed space. In some embodiments, thesystem 100 has a user interface in which a user can manually set and adjust a desired temperature. In some embodiments, the user interface may include a display and interface located on thesystem 100 and/or a user interface remotely disposed from thesystem 100 where the remotely disposed interface may be coupled to thesystem 100 via a wired link and/or a wireless link. - In various embodiments, the
heat transfer assembly 112 heats or cools the air passing there across using a plurality of TECs. The temperature of the TECs may be controlled bycontroller 110 utilizing a pulse-width modulation and/or voltage variance in a manner adapted to reduce power consumption. In some embodiments, thesystem 100 may be powered from the vehicle'sbattery unit 118. Some embodiments may contain an alarm or auto-start function to prevent thebattery 118 from discharging beyond truck-cranking capability. In some embodiments, thesystem 100 may be powered from a power supply independent of the vehicle's battery. In some embodiments, the system may utilize asolar array 120 to use and/or store solar energy. Thesolar array 120 may have an internal battery to maximize the solar energy available for use. In various embodiments, thesystem 100 may store energy for later use by cooling a phase-change medium disposed in an insulated unit, such as, for example, an ice tank. Thereafter, air may be cooled using this stored cooling prior to being used to cool the enclosed space either with or without additional cooling. - Referring now to
FIG. 2 , a cutaway view of a tractor-trailer 200 is shown. Anair comfort system 202 is shown disposed inside a sleeping area of the tractor-trailer 200. Thesystem 202 has vents for dispersing the conditioned air within the enclosed area and also has a vent coupled to an area outside the tractor-trailer for dispersing the exhaust air outside the enclosed area. The size, shape, location and other characteristics of thesystem 202 are only for exemplary purposes and can be varied substantially without departing from the contemplated scope of the invention. - Referring now to
FIG. 3 , an exploded view of one embodiment of aheat transfer assembly 300 can be seen. In the embodiment shown, a plurality offlow tunnels 304 adapted for air to pass therethrough can be seen. On opposite sides of theflow tunnels 304, a plurality ofTECs 302 can be seen. In the embodiment shown, theTECs 302 are in thermal communication with theflow tunnels 304. In addition, on the sides of theTECs 302 opposite of theflow tunnels 304, a plurality offins 306 can be seen. When theheat transfer assembly 300 is being utilized to cool air passing through theflow tunnels 304, electricity is run through theTECs 302 to remove heat from theflow tunnels 304. Similarly, when theHeat transfer assembly 300 is being utilized to heat air passing through theflow tunnels 304, electricity is run through theTECs 302 to add heat to theflow tunnels 304. In either mode of operation, the plurality offins 306 are adapted to dissipate thermal energy from theTECs 302, as needed. - Applicants note that
FIG. 3 shows an arrangement of only one embodiment of a heat transfer assembly that is suitable for the present invention. In additional embodiments, and as discussed in more detail below, heat transfer assemblies of the present invention may be associated with one or more heat pipes for removing heat, such as the heat pipes described and disclosed in U.S. Pat. No. 6,935,409. Applicants further note that several other arrangements of heat transfer assemblies are contemplated, such as the arrangements described in U.S. Pat. No. 7,305,843 and U.S. Pub. Pat. App. No. 2006/0034053. The above-mentioned references have been assigned to the assignees of the present application and are incorporated herein by reference in their entirety. - In a second example, the present disclosure provides additional vehicle air comfort systems and methods. As will be discussed in more detail below, the vehicle air conditioning systems in the second example can incorporate various components of the vehicle air conditioning systems of the first example described above. With reference to
air comfort system 400 shown inFIG. 4 for illustrative purposes, air comfort systems in the second example can comprise anair inlet 416 for receivingunconditioned air 418, aheat transfer assembly 402 for thermally conditioning an unconditioned heat transfer fluid 428 (shown here intubing network 412 as discussed below), and athermal exchange assembly 422 for facilitating thermal exchange between the thermally conditioned heat-transfer fluid 421 andunconditioned air 418. The thermal exchange results in the conditioning of the air, such as by heating or cooling. For instance, if the heat transfer fluid has been cooled during the thermal conditioning, the heat exchange results in the transfer of heat from the unconditioned air to the heat transfer fluid to result in the cooling of the air. Likewise, if the heat transfer fluid has been heated during thermal conditioning, the thermal exchange results in the transfer of heat from the heat transfer fluid to the unconditioned air to result in the heating of the air. - As shown in the embodiment in
FIG. 4 , vehicle air comfort systems in accordance with the second example may also contain anair outlet 424, such as a vent, for outputting the conditioned air into a vehicle. In addition, the systems may contain atubing network 412 for placingheat transfer assembly 402 in fluid communication withthermal exchange assembly 422. - In the embodiment shown in
FIG. 4 ,tubing network 412 is a closed-loop circuit. In addition,tubing network 412 comprises apump 414 for facilitating the passage of the heat-transfer fluid throughsystem 400. However, other suitable tubing networks can also be envisioned by people of ordinary skill in the art. - Similarly, various heat transfer fluids may be used in the vehicle air comfort systems of the present invention. For instance, in some embodiments, the heat-transfer fluid can be a coolant. In other embodiments, the heat transfer fluid can be water. Other suitable heat transfer fluids may also be envisioned by people of ordinary skill in the art.
- Referring again to
FIG. 4 ,heat transfer assembly 402 comprises a plurality offlow tunnels 404,thermoelectric coolers 406 that are in thermal communication with the flow tunnels,fins 408 for dissipating thermal energy from the TEC's, andfans 410 for facilitating the movement of air. However, as will be understood by one skilled in the art, the order and arrangement of the above-mentioned heat transfer assembly components may be varied. Furthermore, in additional embodiments, one or more of the above-mentioned components may be entirely absent. In other embodiments,heat transfer assembly 402 may resembleheat transfer assembly 300 shown inFIG. 3 . In further embodiments,heat transfer assembly 402 may resemble the heat transfer assemblies described and disclosed in U.S. Pat. No. 7,305,843 and U.S. Pub. Pat. App. No. 2006/0034053. In additional embodiments, and as discussed in more detail below,heat transfer assembly 402 may be associated with one or more heat pipes for removing heat, such as the heat pipes described and disclosed in U.S. Pat. No. 6,935,409. - Various thermal exchange assemblies may also be used with the vehicle air comfort systems of the present invention. For instance, and with reference again to
FIG. 4 for illustrative purposes,thermal exchange assembly 422 may comprise afluid inlet 423 for receiving thermally conditionedheat transfer fluid 421, body 425 for facilitating thermal exchange between theheat transfer fluid 421 andunconditioned air 418, andfluid outlet 427 for outputting the heat transfer fluid after the heat exchange. - In some embodiments, the thermal exchange assembly may be a radiator. In other embodiments, the thermal exchange assembly may be a heat pipe, such as a heat pipe described and disclosed in U.S. Pat. No. 6,935,409. In other embodiments, the thermal exchange assembly may constitute one or more components of a heat transfer assembly, such
heat transfer assembly 300 shown inFIG. 3 ,heat transfer assembly 402 shown inFIG. 4 , or one or more of the heat transfer assemblies described and disclosed in U.S. Pat. No. 7,305,843 and U.S. Pub. Pat. App. No. 2006/0034053. In further embodiments, and as will be discussed in more detail below, thermal exchange assemblies may be associated with a dehumidifier for dehumidifying the conditioned or unconditioned air. - In the embodiment shown in
FIG. 4 , afan 420 is also in proximity tothermal exchange assembly 422 for facilitating the thermal exchange between the air and the thermal exchange fluid. However, in other embodiments, more fans may be present to facilitate such thermal exchange. In other embodiments, no fans may be present at all. - Vehicle air comfort systems in accordance with the second example described above have various modes of operation. For instance, in some embodiments, and with reference again to
system 400 inFIG. 4 , thermally unconditionedheat transfer fluid 428 intubing network 412 first passes throughflow tunnels 404. The heat transfer fluid is then thermally conditioned in the flow tunnels by thethermoelectric coolers 406. Next, the thermally conditionedheat transfer fluid 421 entersthermal exchange assembly 422 throughfluid inlet 423. At the same time,unconditioned air 418 enters thesystem 400 throughair inlet 416 and passes throughthermal exchange assembly 422. The simultaneous flow of unconditioned air and thermally conditioned heat transfer fluid throughthermal exchange assembly 422 results in thermal exchange between the heat transfer fluid and the unconditioned air. Consequently, the thermal exchange results in the conditioning of the unconditioned air. Thereafter,conditioned air 426 exitssystem 400 throughair outlet 424. - In the embodiment shown in
FIG. 4 ,tubing network 412 helps pass the heat-transfer fluid through theheat transfer assembly 402 andthermal exchange assembly 422. In addition,fan 420 facilitates the passing of the unconditioned air through thethermal exchange assembly 422. In the embodiment shown,fan 420 may also facilitate the outputting of theconditioned air 426 fromsystem 400. - In some embodiments, air comfort systems of the present invention can cool unconditioned air. In such embodiments, the thermal conditioning of the heat transfer fluid entails the cooling of the heat-transfer fluid. This can occur through the extraction of heat from the flow tunnels by the TEC's (as previously described) as the heat transfer fluid passes through the flow tunnels. Similarly, in such embodiments, the thermal exchange entails the transfer of heat from the unconditioned air to the cooled heat transfer fluid to result in the cooling of the unconditioned air.
- In other embodiments, air comfort systems of the present invention can heat unconditioned air. In such embodiments, the thermal conditioning of the heat transfer fluid entails the heating of the heat-transfer fluid. Such heating can occur by the addition of heat to the flow tunnels by the thermoelectric coolers (as previously described) as the heat transfer fluid passes through the flow tunnels. Similarly, in such embodiments, the thermal exchange entails the transfer of heat from the heat transfer fluid to the unconditioned air to result in the heating of the unconditioned air.
- The conditioning of air by the use of the vehicle air comfort systems of the second example can also be in response to one or more monitored conditions, as previously described. Likewise, as described previously, such monitoring can occur by one or more sensors that may be detectable on a user interface.
- As will be understood by one skilled in the art, the order and arrangement of the above-mentioned steps may be varied while still accomplishing the goals of the present invention. Likewise, in additional embodiments, one or more of the above-mentioned steps may be entirely absent while sill accomplishing the goals of the present invention.
- Furthermore, as will be understood by one skilled in the art, the order and arrangement of the above-mentioned components of a vehicle air comfort system in accordance with the second example depicted in
FIG. 4 may be varied while still accomplishing the goals of the present invention. In particular, in additional embodiments, one or more of the above-mentioned components may be entirely absent. For instance, in some embodiments, and as previously described and shown inFIG. 1 , the vehicle air comfort systems in the second example may contain a thermoelectric cooler exhaust for outputting dissipated thermal energy from the thermoelectric cooler. Likewise, the vehicle air comfort systems of the second example may also include one or more sensors for monitoring one or more operating conditions associated with the system. For instance, the vehicle air comfort systems may comprise sensors that monitor the temperature of the unconditioned heat transfer fluid, the temperature of the conditioned heat transfer fluid, the temperature of the unconditioned air, the temperature of the conditioned air, the humidity of the conditioned air, and/or the humidity of the unconditioned air. Similarly, the vehicle air comfort systems of the second example can also comprise a user interface and/or a controller as previously described and shown inFIG. 1 . - The broad scope of vehicle air comfort systems in accordance with the second example of the present invention can be further illustrated by reference to
FIGS. 5-7 . In particularFIG. 5 depicts vehicleair comfort system 500 withair inlet 516,thermal exchange assembly 522,heat transfer assembly 502, andair outlet 524. The system also containsfan 536 anddehumidifier 537. In addition, vehicleair comfort system 500 containstubing network 512 for placingheat transfer assembly 502 in fluid communication withthermal exchange assembly 522. - In the embodiment shown in
FIG. 5 ,tubing network 512 is also a closed-loop circuit with a plurality of tubes (i.e.,tubes tubing network 512 in this embodiment contains apump 514 for facilitating the fluid communication betweenthermal exchange assembly 522 andheat transfer assembly 502. - In the embodiment shown in
FIG. 5 ,thermal exchange assembly 522 also contains afluid inlet 523, abody 525, and a fluid outlet 527.Thermal exchange assembly 522 is also in close proximity to fan 536 anddehumidifier 537. - Turning now to
FIG. 6 , a more detailed illustration ofdehumidifier 537 is shown. In particular,dehumidifier 537 in this embodiment contains filter unit 540 and fan 542. However, in other embodiments, a dehumidifier may not contain a fan. Other suitable dehumidifiers may also be envisioned by persons of ordinary skill in the art. - Referring again to
FIG. 5 ,heat transfer assembly 502 insystem 500 is shown to contain two sets of a plurality of flow tunnels 504 (504′ and 504″) that are in thermal communication withthermoelectric coolers 506.Heat transfer assembly 502 also containsfins 508 andfan 510. A side view ofheat transfer assembly 502 inFIG. 7 also shows that the heat transfer assembly in this embodiment is associated withadditional fans 510 andthermoelectric coolers 506.Heat transfer assembly 502 in this embodiment is also associated with dehumidifier 737 andheat pipes 550. - Vehicle
air comfort system 500 shown inFIGS. 5-7 can also have various modes of operation. For instance, in one embodiment, flowtunnels 504′ and 504″ receive thermally unconditioned heat transfer fluid from the tubes intubing network 512. Thereafter,thermoelectric coolers 506 facilitate the thermal conditioning of the heat transfer fluid as it passes through the flow tunnels. Next, the heat transfer fluid passes throughthermal exchange assembly 522 as previously described. At the same time,unconditioned air 518 enterssystem 500 throughair inlet 516 and passes throughthermal exchange assembly 522. This results in thermal exchange between the heat transfer fluid and the unconditioned air, and the conditioning of the air. Thereafter,conditioned air 526 exitssystem 500 throughair outlet 524. Before exiting the system,conditioned air 526 may come into contact withdehumidifier 537. Such contact may result in the dehumification of the conditioned air before it exits the system. Furthermore, and as previously discussed,fan 536 may facilitate the thermal exchange process. - Although various embodiments of the method and apparatus of the present invention have been illustrated in the accompanying Drawings and described in the foregoing Detailed Description, it will be understood that the invention is not limited to the embodiments disclosed, but is capable of numerous rearrangements, modifications and substitutions without departing from the spirit of the invention as set forth herein.
