DAVID L. COOK AND FRANK C. PIOKRELL, OF WINCHESTER, KENTUCKY.
.GONDENSER FOR ICE-MACHINES.
SPECIFICATION forming part of Letters Patent No. 534,859, dated February 26, 1 895.
Application filed June 28, 1894:. Serial No. 516.001- (No 111 6910 To all whom it may concern:
Be it known that we, DAVID L. COOK and FRANK O. PICKRELL, both citizens of the United States, residing at Winchester, in the county of Clark and State of Kentucky, have invented new and useful Improvements in Ice-Machines, of which the following is a specification.
This invention relates to an improved condenser for that class of ice machines in which the evaporization of ammonia or other volatile liquid is employed to abstract the heat from a freezing tank or chamber containing the water to be frozen; and it has for its object to thoroughly liquefy the ammonia in order that it may be in the best possible condition to promptly discharge its function the instant it enters the expansion valve.
To this end ourinvention consists in an improved condenser constructed and arranged in the manner hereinafter described and definitely pointed out in the claims following the description, due reference being had to the accompanying drawings forming a part of this specification, wherein- Figure 1 represents a vertical section of our improved condenser, showing the same connected with apreliminarycondensing coil, a brine tank and pump, the liquid ammonia receiver and the suction pipe, of an ordinary ammonia ice machine plant. Fig. 2 is an enlarged vertical sectionof the condenser. Fig. 3, is an enlarged vertical section of the condenser showing a different arrangement of the suction pipe.
Heretofore, in ice machines of the nature described, the gaseous ammonia has frequently been condensed by spraying cold water over coils of pipe through which the ammonia passes while in its gaseous state, and such an arrangement we propose to employ to effect the preliminary condensation of the ammonia gas and then effect the final and complete condensation and liquefaction of the ammonia by an auxiliary condenser constructed and arranged in the manner which we will now proceed to describe.
Referring to the drawings the letter A indicates our improved condenser comprising an outer cylinder a and an inner, concentric cylinder 1) provided with a closed bottom 0 common to both, and with a removable cover 0'. Between the cylinders a and h is coiled in ammonia ice machines the brine contained therein being cooled by the expansion of the ammonia in coilsin the ordinary and well known manner, and communicates with a pump H which forces the brine from the tank up through a pipe 72. into the bottom of the outer cylinder at, the brine flowing over and around the convolutions of the coil D and finally escaping through an overflow pipe h by which latter it is discharged back into the tank G.
I indicates the suction pipe which leads from the evaporating coils andpasses through the center of the inner cylinder b and communicates at its other end with a compressor J of ordinary construction.
In Fig. 3, we have shown the suction pipe I, passing through the space between the cylinders a and b, and coiled therein outside the ammonia pipe coil, the arrangement being otherwise the same as illustrated in Figs. 1 and 2, except that the cylinders a and b, are inclosed in a suitable insulating jacket or casing K, to prevent retardation of the process of operation by influence of the outside atmosphere. This insulation may be provided also in the arrangement shown in Figs. 1 and 2.
In using the arrangement illustrated in Fig. 3, we may dispense with a continuous pumping of brine into the space between the cylinders a and b, and instead thereof fill the said space with brine, as we find excellent results can be obtained in this way. We may, however, use the pump and continuous supply of brine if found desirable.
The operation of our improved apparatus is as follows: The inner cylinder b of the condenser A is filled with ice, and for this purpose the refuse ice which is ordinarily a total loss, can be utilized. The gaseous ammonia first passes through the coil E over which water is constantlysprayed or sprinkled, as usual, by which the ammonia gas is to a greater or less degree condensed, and then passes through the coil D in the condenser A. Brine Ice is being constantly pumped from the tank G by the pump H over and around the convolutions of the coil D and is congealed by the ice contained in the cylinder b, the brine acting as the agent for cooling the ammonia in its passage through the coil whereby it is finally and completely condensed and liquefied, and passes off into the receiver F in a condition to promptly perform its function the instant it enters the expansion valve. The evaporated ammonia after leaving the freezing coils passes up through the suction pipe I to the compressor J and in its passage through the condenser aids in condensing the gaseous ammonia passing through the pipe D to the receiver. We thus utilize the surplus refrigerating power that is latent in the evaporated ammonia after the latter has performed its function in the freezing tanks to aid in thoroughly liquefying the gaseous ammonia in its passage to the receiver, thus effecting a great economy in running and increasing the capacity of the plant. The brine is continuously pumped from the tank Gr through the condenser A and back again to the tank thus using the same brine over and over, and for this purpose a'special pump is not necessary as the usual agitator or circulating pump may be employed for the purpose; or as hereinbefore explained the space between the cylinders a and b, may be filled with brine, and continuous pumping of brine dispensed with, as excellent results are obtained in this Way.
Having described our invention, What We claim is 1. Acondenser forice machines, comprising a cylinder for the reception of ice, and an outer concentric cylinder, said cylinders having a closed bottom and a removable top, and a coiled pipe arranged around said inner cylinder and connected at one end to a condens ing coil and at its other end communicating with a receiver, for the purpose of further liquefying the refrigerating agent that has previously been partly liquefied,substantially as described.
2. A condenser for ice machines, comprising a cylinder for the reception of ice, a coiled pipe arranged around said cylinder and connected at one end to a condensing coil and at its other end communicating With a receiver, an outer cylinder inclosing said coil and inner cylinder, said cylinders having a closed bottom and a removable top, and means for circulating brine between said cylinders and about said coil, for the purpose of further liquefying the refrigerating agent that has previously been partly liquefied,substantially as described.
3.- A condenser for ice machines, comprising a cylinder for the reception of ice, and an outer concentric cylinder, said cylinders having a closed bottom and a removable top, a coiled pipe arranged around said inner cylinder and connected at one end to a condensing coil and at its other end communicating with a receiver, and a suction pipe leading from the evaporating coils to a compressor and passing through said condenser, for the purpose of further liquefying the refrigerating agent that has previously been partly liquefied, substantially as described.
In testimony whereof We have hereunto set our hands and affixed our seals in presence of two subscribing Witnesses.
