Abstract

A transport refrigeration/air conditioning system includes a fuel cell which is electrically connected to at least one of the compressor drive motor, evaporator fan motor or condenser fan motor to provide electrical power thereto.

Description

    TECHNICAL FIELD
  • This invention relates generally to refrigerant systems and more particularly, to such systems powered by fuel cells.
    • BACKGROUND OF THE INVENTION
  • There are various types of dedicated refrigerant systems, such as refrigeration air conditioning. systems used in mobile or tray applications. That is, trucks/trailer refrigerated compartments, as well as refrigerated containers, which include associated dedicated refrigeration systems for maintaining a required temperature condition in the confines of the storage space of the vehicle or container. Similarly, buses and recreational vehicles often include associated dedicated air conditioning systems, most often located on the roofs of the vehicles, for conditioning the air Within the interior of the vehicles.
  • The truck trailer refrigeration systems may be of the two main types. in one arrangement, the truck trailer includes an engine, such as a diesel engine, which is drivingly connected, by a belt, a clutch, gears or the like, to the compressor, and to the evaporator and condenser (or gas cooler) fans. In another arrangement, a diesel engine may be drivingly connected to a generator/alternator which, in turn, provides electrical power to the compressor and the fans.
  • In refrigerated container systems, the refrigeration units are adapted to be plugged into an electrical power source, such as on land or aboard a ship, to thereby provide electrical power to The compressor and fans of the refrigeration system. However, to allow the container refrigeration system to operate when there is no direct source of electricity present, such as aboard a trailer or rail platform, or on a remote dock, a diesel engine is provided to drive a generator which, in turn provides a required source of electricity to the compressor and fans.
  • If no source of electricity is available, then normally an internal combustion engine is required to drive at least the generator, and possibly the compressor and the fans. Quite often, this engine would be a stand alone engine that is exclusively dedicated to run an air conditioning or refrigeration system. In this regard, there are various undesirable aspects to the use of the internal combustion engine in this manner. Firstly, it produces exhaust gases which are harmful to the environment. Secondly, it generates substantial noise during operation. As known, both issues are becoming more important in environmental considerations and are governed by various regulations and legislation requirements.
    • DISCLOSURE OF THE INVENTION
  • In accordance with one aspect of the invention, the generator and/or dedicated engine for a transport refrigeration/air conditioning system is replaced with a fuel cell for providing the electrical power needed for the refrigeration/air conditioning system.
  • In accordance with another aspect of invention, a fuel cell replaces a direct source of electric power for a transport refrigeration/air conditioning system.
  • In the drawings as hereinafter described, a preferred embodiment and a modified embodiment are depicted; however, various other modifications and alternate constructions can be made thereto without departing from the spirit and scope of the invention.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is a simplified illustration of the general concept of the present invention.
  • FIG. 1A is a simplified refrigerant system schematic that relies on the use of a fuel cell as a power supply.
  • FIG. 2 is a schematic illustration of one embodiment thereof as incorporated into a truck/trailer.
  • FIG. 3 is an alternative embodiment thereof.
  • FIG. 4 is a schematic illustration of the present invention as incorporated into a recreational vehicle air conditioning system.
    •  DETAILED DESCRIPTION OF THE INVENTION
  • FIG. 1 is a simplified illustration of a transport refrigeration/air conditioning system 11 connected to a fuel cell 12 incorporated therein. A transport refrigeration/air conditioning system may be a refrigeration system for a truck/trailer or container, or it may be an air conditioning system for a bus or recreational vehicle, most likely located on its roof.
  • In any case, as shown in FIG. 1A, a basic refrigeration/air conditioning system includes, in a serial flow relationship, a compressor 10 driven by an electric motor 35, a heat rejection heat exchanger 15, an expansion device 20 and an evaporator 25. An evaporator fan 31 blows air over the external surfaces of the evaporator 25 and a heat rejection heat exchanger fan 33 blows air over the external surfaces of the heat rejection heat exchanger 15, The evaporator fan 31 is driven by an electric motor 32 and the heat rejection heat exchanger fan 33 is driven by an electric motor 34. The electric motors 32, 34 and 35 would normally be connected to an electric DC bus 36 that converts the DC current from the fuel cell 12 into the AC current. However, motors 32, 34 and 35 can also be of the DC type, such that no DC bus would be required. Any of the motors 32, 34 and 35 can also be connected to a variable speed drive to operate the motors at variable speeds.
  • It should be understood that in the context of this invention, the heat rejection heat exchanger 15 can be of a condenser type, if it operates in a two-phase regime typical of subcritical cycles, or a gas cooler type, if it operates in a single phase gas regime typical of transcritical cycles. The transcritical cycles are common when, for example, CO2 is used as a refrigerant. The schematic shown in FIG. 1A is simplified, and as known in the art, may also include additional components such as, for example, receivers, accumulators, economizer heat exchanger, liquid injection and vapor injection lines, intercooler heat exchanger, liquid-suction, heat exchanger, etc. The compressor 10 can be a single or Multi-Stage type compressor. The compressor 10 can have special provisions for vapor injection or liquid injection. The compressor can be of a different type such as, for example, a reciprocating compressor, a screw compressor, a scroll compressor or a rotary compressor. The compressor can also include several compressors connected in series or in parallel (or so-called tandem) arrangement, as known in the art.
  • Further, as shown in FIG. 1, the fuel cell 12 can be providing the entire electrical power needs for the transport refrigeration/air conditioning system. However, there may be some systems configurations where an alternate electrical power source or dedicated engine (with associated components) 13, may also he included. In such cases, one of the two systems 12 or 13 can act as the primary electrical energy source while the other acts as a standby system or a backup system used in emergencies. One example of such an auxiliary system operation is a standby operation where an electric motor plugged into an electric grid outlet was previously used to temporarily provide power to the components of a refrigeration/air conditioning system. Switching to such mode of operation may be required, for instance, due to noise level limitations exceeding by a combustion engine during nighttime in urban areas. Another example may be related to a combustion engine failure. Further, in many locations, such an electric grid power supply may not be available, therefore the benefits of the fuel cell providing power during standby or backup emergency systems become apparent.
  • In FIG. 2 there is schematically shown a truck/trailer 14 which includes a tractor 16 which is attached to a trailer 17 in a conventional manner. This truck/trailer 14 may also take the form of a smaller truck wherein the tractor 16 forms an integral part of the trailer 17, with such a combination simply being referred to as a truck.
  • In the case of either a truck or a truck/trailer arrangement, the internal cargo space is cooled by way of a refrigeration system 18 which is commonly attached to the front of the trailer in a conventional manner as shown. The refrigeration system 18 has components similar to the components of the refrigeration/air conditioning system 11 described hereinabove. A fuel cell 19 is installed adjacent the refrigeration system 18 and is electrically connected thereto such that the fuel cell provides electrical power to the compressor, evaporator fan and condenser fan motors within the refrigeration unit 18. In this manner, the refrigerant system 18 can be made to be fully independent of an engine, thus allowing for quiet and environmental friendly operation of the system.
  • An alternative embodiment is shown in FIG. 3, wherein a fuel cell 21 is provided in the tractor 16 portion of the unit rather than being associated directly with the refrigeration unit. In this case, the same fuel 21 can be used to provide the source of power to operate the tractor/trailer as well as power the refrigeration system 18.
  • In FIG. 4 there is shown a recreational vehicle 26 with an associated dedicated air conditioning unit 27 located on the roof thereof. The air conditioning unit 27, which has the same basic components as the earlier described refrigeration/air conditioning system 11. Again, a fuel cell 28 is electrically connected to the air conditioning unit 27 so as to provide the required power for the electric motors of the air conditioning unit 27.
  • While the present invention has been particularly shown and described with reference to preferred and modified embodiments as illustrated in the drawings, it will be understood by one skilled in the art that various changes in detail may be made thereto without departing from the spirit and scope of the invention as defined by the claims.
