1 Claim.
This invention relates to refrigeration and particularly to a means for circulating a refrigerated current of water, brine Yor fluid in which gas, due to the volatilization of the refrigerating medium is utilized to cause the circulation of the refrigerated uid so that the refrigerated fluid is delivered to a tank or receptacle and thereafter the said fluid is again circulated through the receptacle containing the refrigerant so that the refrigerated uid is kept in circulation.
It is an object of this invention to utilize the gases and pressure developed from the volatilization of dry ice to effect the said circulation, as stated.
It is a further object of this invention to provide a receptacle for the dry ice which has an airtight construction except for a vent or discharge pipe through which the gases escape, it being understood that sufcient pressure will develop within the said receptacle to circulate the refrigerated fluid.
It is an object of the invention furthermore to provide an arrangement of parts and a combination of elements operative to produce the result stated and the parts of which are simple in construction and comparatively inexpensive to operate and maintain.
With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.
In describing the invention in detail, reference will be had to the accompanying drawing forming part of this application, wherein like characters denote corresponding parts in the several views, and in which- Figure 1 illustrates a view in elevation, partly in section of an apparatus embodying the invention;
Figure 2 illustrates a horizontal sectional view of the dry ice receptacle showing in plan the circulating pipes;
Figure 3 illustrates a sectional view of the injector used in the system; and
Figure 4 illustrates a sectional view of a fragment of the ice chamber showing the connection of the pipe through the side thereof.
In the drawing 5 denotes a receptacle for containing dry ice and it has a cover 6 attached to a flange 1 thereof by fastenings 8 such as screws or the like, although ordinary clamps might be employed for holding the cover which should have an airtight joint with the anges 'I. The receptacle has a pipe 9 connected to it which communicates with the interior of the receptacle and the said pipe may have a check valve Iii, a manually operated valve or thermostat II anda safety valve I2, by which the gas escaping from the receptacle 6 may be controlled. A tank or receptacle I3 is preferably supported in any appropriate manner with its bottom above the plane of the bottom of the receptacle 5. A coil I4 is located in the receptacle 5, preferably at the bottom thereof, so that the dry ice I5 in the receptacle 5 will be supported by the coil, although the coil, of course, may be embedded in the mass of dry ice. In any event, the fluid in the coil is cooled and circulation of the cooled liuid is accomplished through the employment of the gas pressure escaping through the pipe 9, and it is shown that the said pipe 9 communicates with a chamber Iii of enlarged area or capacity as compared with the said pipe 9, so that the gas which escapes from the pipe 9 causes the injection of the refrigerated fluid which also enters the chamber through the pipe I'I which is a part of the circulating system including the coil I4.
The pipe I8, which is also a part of the circulating system, is attached to the bottom of the receptacle I3 and communicates therewith, preferably through the bottom of said receptacle. l-Ience, it is seen that as the refrigerated fluid passes from the coil through the pipe I'l to the chamber I6, the gas escaping from the receptacle 5 acts to force the refrigerated fluid into the tank I3 through the nipple or pipe I9, which communicates with the said tank I3 through its bottom or otherwise, so that a circulating system is produced whereby the refrigerated fluid is delivered to the tank and is then permitted to gravitate therefrom through the coil for a repetition of the circulation and operation.
The pipe 9 is guarded by a screen 9a to prevent the entrance of dust or foreign substances which might choke the injector, although a screen for the purpose may be provided at any convenient location.
We claim:
In a refrigerating apparatus, a receptacle for containing a volatilizable refrigerant, pipes for vthe circulation of refrigerated liuid having a contacle gravtates through the said coil, a chamber with which the other pipe communicates, the said chamber having a connection with the second mentioned receptacle through its bottom, a. pipe connected to the interior of the first mentioned receptacle for conveying gas under pressure due to the volatilization of the refrigerant,
the said pipe extending into the chamber and forming an injector for forcing fluid entering the said chamber through the pipe of the said coil into the second mentioned receptacle.
