Definitions

  • the present invention relates to refrigerated containers having self-contained refrigeration systems. Even more particularly, the present invention relates to an improved portable self-contained cooler/freezer apparatus wherein either an external bulk supply or self-contained carbon dioxide canister dispense CO2 or like liquid coolant through a manifold and plate like diffuse system to regulate temperature within the container, and wherein a temperature controlled solenoid valve dispenses CO2 or like coolant as needed into the container interior.
  • the plate like diffuser allows use of the shipping container walls to cool.
  • truck lines use refrigerated trucks to carry food products over long distances.
  • a truck is designed to carry either frozen foods or foods that must be maintained in higher, but still refrigerated temperatures, such as, for example, 40°F.
  • These trucks typically carry either refrigerated or frozen food only and differ from the typical common carrier truck which is unrefrigerated and which carries any of a number of bulk, unrefrigerated commodities, such as palletized loads of any general merchandise, product, or equipment.
  • common carrier which is unrefrigerated and which carries any of a number of bulk, unrefrigerated commodities, such as palletized loads of any general merchandise, product, or equipment.
  • trucks that are not refrigerated but which have space for holding any number of general commodities.
  • U.S. Patent No. 3,633,381 entitled "Open-Cycle Portable Refrigerator.”
  • a portable refrigerator employing an open cycle system.
  • a stored compressed gas, such as carbon dioxide is passed from the storage container through an evaporator which comprises a serpentine passageway for the gas in a surrounding medium, such as water, an aqueous solution, which is maintained frozen due to the passage of the expanding compressed gas through the coiled passageway.
  • the temperature of the evaporated medium is lower than the ambient temperature of the interior or the container comprising the storage portion of the refrigerator which is cooled thereby.
  • the gas passing through the evaporator may be exhausted into the interior of the container whereby the cooler air which is next to the evaporator medium is circulated throughout the interior of the container.
  • a portable ice chest having a refrigeration unit is disclosed in U.S. Patent No. 3,959,982.
  • a substantially closed refrigeration receptacle in fluid communication with the outlet side of the primary evaporator receives the refrigerant which may not have completely evaporated, and separates the phases by venting the evaporated gas phase to the atmosphere while directing the unevaporated liquid refrigerant into a second evaporated coil wherein it is completely evaporated.
  • the thermostatically controlled valve regulates the flow of refrigerant to the primary evaporator as a function of temperature within the chest.
  • the Rhoad U.S. Patent No. 3,961,925 provides a portable self-contained refrigerated storage and transportation container for preserving perishable commodities and includes an insulated storage chamber for perishable commodities.
  • a recirculating liquid cooling system is provided within the container and includes conduit and nozzle means disposed within the storage chamber adapted to spray a liquid coolant, such as chilled brine directly onto the perishable commodities to maintain them in a uniform cooled temperature.
  • the sprayed liquid coolant is collected in the bottom portion of the storage chamber.
  • a closed refrigeration system is also provided within the container and includes in part heat exchange means disposed within the bottom portion of the storage chamber for cooling the sprayed liquid coolant which has collected there.
  • the Franklin U.S. Patent 4,502,293 entitled “Container CO2 Cooling System,” provides a generally rectangular container that includes an insulated top, bottom, opposite sides and opposite end walls.
  • An upstanding transverse insulated hollow housing is mounted within the container adjacent one end thereof and a CO2 snow cabinet constructed of good heat transfer material is disposed within the housing with opposing wall portions of the cabinet and housing passing exteriorly about the cabinet.
  • a heat insulative horizontal baffle is mounted within the container spaced below the top wall and extends between the sidewalls thereof. The baffle defines a cooled air passage beneath the top wall extending lengthwise of the container.
  • the airflow passage includes an outlet end adjacent and in at least reasonably closed communication with the end of the cooled air passage adjacent the aforementioned one container end wall and an inlet end opening outwardly of the housing into the interior of the container below the baffle.
  • the end of the cooled air passage adjacent the other container end wall opens into the interior of the container and thermostatically controllable air pump structure is provided to effect airflow inwardly of the inlet of the airflow passage, through the airflow passage and into the cooled air passage.
  • structure is provided for spray discharging of liquid CO2 into the interior of the upper portion of the cabinet and into the airflow passage at points spaced therealong in order to form CO2 snow therein.
  • the Combs U.S. Patent No. 4,576,017 discloses a container for maintaining its contents at a desired temperature for an extended period of time, such as for use in shipping contents in a frozen condition.
  • the container includes an outer shell which is substantially air tight and which has an inner surface, a pass of heat exchange medium, a support structure for the heat exchange medium, and means for maintaining an air space between the contents of the container and substantially the entire inner surface of the outer shell of the container and between the contents of the container and the support structure for the heat exchange medium for allowing convection current to develop in the inner space which circulates past the heat exchange medium and maintains a substantially uniform temperature around the contents of the container.
  • a storage device having a walled inner and outer container and a compressed gas supply contained within the device.
  • a conduit is provided from the gas supply to the inner container and a control valve for the conduit responsive to pressures above and below a super atmospheric pressure value are provided for closing and opening the valve.
  • the present invention solves the problems and shortcomings of the prior art in a simple straightforward manner by providing an improved portable transportable refrigeration system for use on common carrier type truck lines, for example.
  • the apparatus contains a self-supporting container having an interior for carrying refrigerated or frozen cargo and adapted to be lifted by a forklift, for example.
  • a canister for containing a liquid refrigerant under pressure is positioned in the upper end portion of the container interior.
  • a pivotally movable perforated baffle plate extends transversely across the container interior at the upper end portion thereof and is positioned directly under the canister.
  • the baffle plate can optionally contain the canisters and manifold with a "floor” to hold frost, ice, and coolness against the canisters and manifold when the device is preliminarily charged with coolant from an external "bulk” source.
  • a temperature control communicates with the canister for controlling temperature within the interior and includes a manifold header for discharging liquid refrigerant from the canister.
  • the manifold header includes a preferably externally extending inlet opening receptive of a source of bulk CO2 for quick charging the unit interior with CO2 so that the canisters need only maintain coolness. Further, the manifold can be used to charge the canisters when empty with liquid CO2 from any bulk external supply source of liquid CO2 or like refrigerant.
  • a pressure control valve controls the pressure of fluid discharged from the canister, and a temperature valve is positioned in the header downstream of the pressure control valve which thus controls temperature within the interior and over a wide temperature span of, for example, -20°F to 70°F. Henceforth very accurate temperatures can be maintained.
  • Canisters have bent tubes that can be positioned to vent either gas or liquid. For liquid, the tubes point down and for gas the tubes point up.
  • the container includes a base plate having two spaced apart parallel slots adapted to be engaged by a forklift lifting device.
  • the apparatus in the preferred embodiment includes an array of perforations extending over a substantial portion of the hinged baffle plate.
  • the canister, the pressure control valve, and the temperature control valve, as well as the header are positioned above the baffle plate.
  • the manifold header is in the elongated tube having an external inlet that allows the manifold to be connected to an external CO2 "bulk" supply for either charging the canisters when empty, or for quick cooling the container interior before a shipment.
  • the container includes a vertical access doorway that extends substantially the full height of the container, terminating below the hinged baffle plate in its hinged position.
  • the apparatus includes a valve which communicates with internal vent tubes that can optionally remove either gas or liquid from the canister.
  • the valve includes bent tubes or ducts extending internally and to the side inner wall of the canister from the valve structure, and positioned to dispense either liquid or gas respectively when the canisters are in their usual horizontal position.
  • the manifold header is positioned above the baffle plate and generally between the canisters.
  • the hinged transverse plate with perforations allows the canister, the pressure control valve, the temperature control valve and the header to be "quick frozen" by an external source of liquid refrigerant via the manifold header before the entire apparatus is shipped.
  • the perforations thus define with the sides of the overall container a smaller interior space that closely surrounds the canister, and the header, so that when liquid refrigerant from an external source is added to the smaller interior area above the baffle, the smaller interior area of the baffle, the smaller interior space is filled with solid CO2 and snow and at very low temperatures without affecting the components of the refrigeration system used to ship at temperatures above 0°F.
  • FIGS 1 - 3 show generally the preferred embodiment of the apparatus of the present invention designated generally by the numeral 10.
  • FIG 1 there can be seen an enlarged rectangular transportable box-like container 12 having an upper surface 13 and a plurality of side walls 14, 15, 16, 17 forming an enclosure with a bottom 18 portion of the container.
  • the bottom 18 includes a pair of spaced apart recesses 19, 20, for example, which can be used to form a connection with the times of a fork lift so that the container 10 can be easily moved and transported about, such as during unloading or loading of trucks.
  • the apparatus 10 can include an access doorway 21 that would preferably be vertically oriented and pivotally attached, having closure latches 22, 23 thus allowing access through door 21 into the interior 24 of container 12.
  • Container 12 would be manufactured, for example, of welded stainless or welded aluminum construction.
  • the bottom section of container 12 defines a reservoir to hold any water that accumulates during use.
  • a valved drain 5 can be used to remove water during or after use from the reservoir.
  • a hinged transverse perforated baffle 25 extends across the upper portion of container 12 defining an uppermost interior compartment 26 that contains canisters 27, 28.
  • Baffle plate 25 would be hingedly connected to container rear wall 16 along edge 25A so that the baffle plate 25 can swing down into a generally vertical position adjacent rear wall 16 (when the apparatus is to be used for shipping product in a cooled but not frozen condition), the baffle plate 25 waved swing into a horizontal position as shown in Figure 1, creating the confined compartment area 26 about canisters 27, 28 when the apparatus is to be used for shipping product in a frozen condition.
  • Plate 25 would be held in the upper horizontal position using a latch (not shown) or removable thumb screws or such like means.
  • Canisters 27, 28 are preferably canisters containing liquid refrigerant, preferably carbon dioxide or a like refrigerant and the canisters are positioned upon their sides in a horizontal position, as shown in Figures 1, 2 and 3.
  • the plate 25 preferably includes a plurality of perforations therethrough designated as 29 in Figure 1.
  • the canisters 27, 28 are each equipped with exit valves 30, 31 which communicate with header 32 that connects with manifold header 33 positioned generally between canisters 27, 28 and generally parallel thereto, as shown in Figure 1.
  • Manifold 33 has an externally extended end portion 33A that is an inlet fitting which allows a "bulk" external source of liquid refrigerant such as CO2 to be transmitted to the manifold header 33 for two purposes as selectively desired.
  • the manifold header can "quick cool" the interior 24 with CO2 from the bulk source before a shipment. Normally, if frozen foods are being shipped, the baffle plate is put in the upper position ( Figure 1) and CO2 is blasted into the confined compartment 26 covering the canisters 27, 28 and header with ice and generally filling the area 26 with ice and snow. Secondly, the manifold can be used to fill the tanks 27, 28 when they are empty.
  • a valve interfacing manifold 33 and header 32 controls flow from manifold fitting 33A to either tanks 27, 28 (for filling) or to header 33.
  • the container 12 would preferably be equipped with an externally mounted temperature gauge 34 so that a user can view the internal temperature 24 by viewing the thermometer 34, even when the door 21 was closed.
  • Pressure gauge 35 could also extend externally of container 12 so that the pressure within header 32 could be viewed externally of the apparatus 10.
  • the valves 30 and/or 31 would be opened allowing carbon dioxide to flow through header 32 and into perforated tube 33 so that CO2 would enter the internal portion 26 of box 12 above perforated plate 25 causing cold air to refrigerate that portion of the box 12 interior 24.
  • transverse plate 25 allows the interior 26 of box 12 above plate 25 to be preliminarily frozen using, for example, a blast of CO2 from an external source, a source other than canisters 27, 28 before the box is to be shipped.
  • This allows a frozen condition above plate 25 which supplements the amount of cooling that would otherwise be required to keep the entire container 12 at a particular refrigerated temperature.
  • the common carrier would simply blast the container for a specified period of time and quickly lower the temperature of the container to reduce the work load on the canisters. This allows the boxes to be shipped over much longer distances than ordinarily would be possible if only cooling from canisters 27, 28 are used.
  • FIG. 2 is alternate construction for the arrangement of canisters 27, 28 and the header and valves.
  • a pair of canisters 27, 28 having positioned therebetween an elongated header 41 which is a gas exhaust header and includes tube sections 42-46 which are generally parallel and a plurality of elbow tubes 47-50 connecting the tube sections, as shown in the drawings end to end, to form an elongated header for gas exhaust.
  • a pair of dual on/off exhaust valves, (See Figures 4 and 5) 51, 52 each provide a gas feeder tube 53, 54 and a liquid feeder tube 55, 56 respectively.
  • a transverse flow line 59 connects valves 51, 52 while a lowermost transverse flowline 67 also connects the lower end portion of valves 51, 52.
  • Pressure regulator 57 regulates the pressure of gas leaving canisters 27, 28 through transverse header 59.
  • Discharge flowline 60 communicates with pressure regulator 57 and with dual temperature regulator valve 62.
  • a temperature probe 61 senses temperature within the container 24 below baffle 25 so that the temperature probe dictates when gaseous CO2 is discharged through valve 62 through discharge line 63 which communicates with gas exhaust header 41.
  • Transverse flowline 67 receives liquid CO2 from valves 51, 52 as the lines 55, 56 typically collect liquid CO2 from canisters 27, 28. Liquid CO2 thus enters liquid carrying heat exchanger coil 65 through flowline 68.
  • the liquid carrying heat exchange coil 65 can be provided, as shown in the drawing with a plurality of transverse fins 70 for efficiency purposes in heat transverse. In heat transfer between the air within container 12 interior and the liquid carrying coil 65.
  • Header 72 is preferably an elongated cylindrical tube having a plurality of openings spaced along the length thereof, with an inlet 72A extending externally of the container 12 so that a bulk CO2 source can be used to preliminarily charge and cool container 12.
  • the header 72 could be piped (and appropriately valved) to canisters 27, 28 so that the canisters 27, 28 could be charged when empty from a bulk CO2 source via header inlet 72A.
  • the elongated header tube 72 is in communication with gas exhaust header 41 so that the gas contained within header 41 eventually can be discharged through openings in header tube 72.
  • FIG. 3 shows another embodiment of the invention wherein a transverse pan 75 is used immediately under the gas exhaust header tubes.
  • the pan 75 can wrap around the canisters 27, 28 as shown to form a tray that holds ice and snow.
  • FIGS 4 and 5 show more particularly the construction of dual on/off valves 51, 52 each comprising a valves body 80 that communicates with a pair of internal passageways 81, 82.
  • the passageway 81 communicates with tubes 53, 54 while the passageway 82 communicates with tubes 55, 56.
  • Transverse passageways 88, 89 communicate respectively with externally extending transverse ports 86, 87 which in the preferred embodiment form connections with transverse headers 59, 67.
  • header 59 connects to the uppermost port 86 of valves 51, 52 while the lowermost port 87 connects with header 67.
  • each valve by rotating the spigots 83, 84 open the ports 88, 89 so that flow can proceed respectively via tubes 53, 54 and passageway 81 (with respect to the opening 88 and spigot 83) or via tubes 55, 56 through passageway 82 and opening 89.
  • either gas or liquid or both could be removed from canisters 27, 28.
  • FIG. 6 there can be seen a piping detail which specifies a piping arrangement that can be used to either charge the canisters 27, 28 when they are empty, or blast liquid or gas CO2 directly into the container interior.
  • the inlet header 33 is equipped with an external fitting 33 that extends beyond the container wall 14.
  • the header 33 connects with a tee 90 which carries a pressure indicator.
  • a second downstream tee 91 communicates with an elbow 92 that is equipped with a valve 93.
  • the valve 93 controls the flow of fluid from tee 91 through elbow 92 and downstream to header 94 which is equipped with a series of preferations or ports 95.
  • valve 93 When valve 93 is open, and a source of bulk CO2 attached at fitting 33, a large volume of liquid or gas CO2 can be immediately charged into the container interior via the header 94 and more particularly through the series of ports 95.
  • valve 93 When valve 93 is closed, the header 33 can be used to either fill canisters 27, 28 through cross 95 which contains a pair of lateral lines 96, 97 which would communicate through appropriate piping with valves 30, 32 so that when valve 93 is closed, bulk CO2 added through fitting 33A can fill canisters 27, 28.
  • Downstream of cross 95 is a pipe section 98 which communicates with temperature responsive control valve 99 that communicates with downstream affluent header 100 and more particularly with the orifice fitting 101 portion thereof. This would be a relatively small orifice opening 101.
  • the valve 93 would first be opened to charge the container 12 with a blast of CO2 to lower the temperature. After this initial blast from a bulk CO2 source, the valve 93 would be closed.
  • the temperature responsive valve 99 would only open when needed to supply CO2 from canisters 27, 28 into the container interior by discharging the CO2 into the cross fitting 95 so that it could flow through the valve 99 to the orifice 101.
  • a bulk CO2 source could be initially used to greatly lower the temperature of the cargo and thereafter the canisters would only be needed to maintain that temperature.
  • the bulk source could be used to supply much of the cooling that was needed to lower the temperature with the canisters 27, 28 only being needed on a maintenance basis after the shipment was sent.
