My invention relates to improvements in refrigerating and Ventilating systems forrefrigerator cars.
Generally, it is my object to provide simple, durable and effective means in a car or other enclosure for refrigerating the goods in the lading space and for circulating the air therein and Ventilating the same.
In practice, and particularly in refrigerator cars, it is desirable, to avoid the use of fans for Ventilating the lading space and circulating the air therein, and when a fluid circulatory system is employed, it is desirable not only to avoid the use of a pump in the system, but also to provide a system in which the temperature of the fluid may be reduced effectively as my means of a quantity of ordinary ice or the modernly manufactured solid carbon dioxide.
More particularly, it is my object to provide a circulatory system for a heat exchanging fluid and a refrigerating medium for cooling such fluid, the two being so arranged within a car or other enclosure as to cause the circulation of air therein and the circulation of the fluid in said system, all by gravity.
Another object is to supply, 1n such a combination, means for causing the regulated introduction of fresh air to the car and the regulated exhaustion of used air therefrom, by gravity.
A further object is to provide in the circulatory system, an assembly of independent units each adapted to be controlled independently of the other, whereby refrigeration, as effected by the said circulatory system, may be regulated to suit varying conditions.
With the foregoing and other objects in view, which will appear in the following description, the invention resides in the novel combination and arrangement of parts and in the details of construction hereinafter described and claimed.
In the drawings, Fig. 1 is a longitudinal central sectional view of a refrigerator car containing therein equipment embodying my invention; Fig. 2 is a horizontal sectional view taken as on the line 2-2 of Fig. 1; Figs. 3 and 4 are vertical sectional views taken as on the lines 3 3 and 4 4 of Fig. 1,
1929. Serial No. 357,696.
respectively, and Fig. 5 is a detail perspective view particularly illustrating the construction of the circulatory system for the refrigerating fluid.
Referring to the accompanying drawings, it will be noted that the illustrated structure includes an ordinary refrigerator car c0111- prising a body A and trucks 10 therefor, the body consisting of the usual insulated floor 11, sides 12, ends 13 and roof 14. lVithin the car is a false end 15 and a false Hoor B, the latter being of openwork construction and consisting of spaced transverse slats 16 secured to spaced timbers 17 laid edgewise on the floor proper 11, lengthwise of the car. The false end 15 provides a bunker compartment C at one end of the lading chamber D and the false floor B provides a refrigerating and air circulating space E beneath said lading chamber, which space is divided into sections by the timbers 17. The false end 15 stops short of the ceiling of the car leaving an opening 18 between the upper portion of the lading chamber D and the upper portion of the bunker compartment C, which provides communication between said chamber and compartment. Said false end 15 also falls short of the floor 11 of the car, leaving :In opening 19 between the lower portion of the bunker compartment C and the space E between the floor proper 11 and the false floor B. which provides communication between said compartment C and space E. Within the bunker compartment C are a number of sills 20 supporting boards 21 upon which a tank 22 rests. The sides and ends of this tank are spaced from the sides and ends of the bunker compartment C to permit of the passage of air through the compartment and about said tank. Coiled about the tank are a number of pipes 23, 24, 25, 26 and 27, the upper end of each pipe taking off from an upright header 28 near the top of the tank 22. From a point near the bottom of the tank 22 each pipe has a reach extending through the space E to the end of the car opposite the compartment C and has a return reach, at slightly higher elevation, extending back toward said compartment. This return reach branches upwardly between the false end 15 of an insulating panel 29, thence connects with said header 28, the upwardly extending branch of each of said pipes being fitted with a suitable valve 30. The header 28 communicates at its upper end with a supply and expansion reservoir 31 having a filler neck 32 extending upwardly through the roofl 14 of the car.
Within the compartment C and at the ends thereof and adjacent to the ends of the tank 22 are two upright Ventilating ducts 33 and 34, which are provided with dampers 35 and 36, respectively. Duct 33 communicates at its upper end with the outer atmosphere through the end of the car, and at its lower end with the interior of compartment C at the lower ortion thereof. Duct 34 communicates at 1ts upper end with the interior of the compartment C at the upper portion thereof and communicates at its lower end, through the floor of the car, with the outer atmosphere.
Ice, with or without salt, or a substitute therefor, such as dry ice is placed in the tank 22. The circulatory system consisting of the pipes 23, 24, 25, 26 and 27 is supplied with a suitable heat exchanging liquid by introducing such liquid into the reservoir 31 and through the header 28 to said pipes.
The refrigerating medium in the tank 22 reduces the temperature of the air about the tank and reduces the temperature of the liquid in the pipes encircling the tank. In thus cooling the pipes at the tank 22, the liquid in said ipes is caused to gravitate through the coi ed pipe portions in the compartment C, through the reaches of pipe in `the space E beneath the false floor B, and through the upright branches of said pipes returning to the upper ends of the coils at the tank. The air in the compartment C about the tank 22 descends upon bein cooled and enters the space E beneath the alse floor B, where it is further cooled about the reaches of pipe in said space. This air, in taking the place of the warmed air, drawn into the upper portion of the compartment C from the upper portion of the lading chamber D, passes upward through the false iloor B into the lading space where it refrigerates the goods located therein. Rising in this space as its temperature is increased in the presence of the lading, the air reaches the upper portion of the chamber D and is thence impelled into the upper portion of the compartment C by reason of the down flow of air therein about the coiled pipes and tank. Thus, the refrigerating medium in the compartment C serves, not only to refrigerate the aii` therein and cause it to circulate through the structure as explained, but also refrigerates the liquid in the portions of the pipes 23, 24, 25, 26 and 27 coiled about the tank, causing the liquid to circulate in said pipes and keep cold the reaches thereof within the space E beneath the false oor B.
The different units of the assembly may be independently controlled, at will, by suitably manipulating the valves 30, it being ossible by adjusting these valves, selectivey, to graduate or entirely cut off the flow of the liquid through the pipe reaches in the different sections of the space E between the different timbers 17, beneath the false floor B. Thus, the effectiveness of the different. units in the'circulatory system may be uniformly altered at will, or varied independently, as desired, to accommodate non-uniform loadings.
The manner employed in the coiling of the pipes about the tank 22 provides a maximum length of contact between tank and pipes and at the same time provides a relatively sharp pitch in the coils, whereby an active circulation of the liquid in the pipes is assured.
While I have shown a tank for a refrigerating medium about which the pipes 23, 24, 25, 26 and 27 are coiled, it will be understood that the tank may be dispensed with and the pipes themselves or any other suitable receptacle within the coils may be employed to contain tle particular refrigerating medium emp o e l Yhen the dampers 35 and 36 in ducts 33 and 34 are opened, fresh air gravitates into the lower portion of compartment C and used air gravitates out of the car from the upper portion of said compartment, the temperature of the air within said ducts being affected by the refrigerating medium employed within that compartment. By appropriately regulating these dampers 35 and 36 the car will be ventilated in the desired degree.
