A refrigerator direct injection system as claimed in, 36. 21. Therefore, in many practical applications of refrigeration, the compressor in high pressure (condensation pressure) to low pressure (evaporation pressure) ratio (compression ratio) high conditions for work. A refrigerator expansion line as claimed in, 30. A main slurry tank 36 receives and stores the discharge from evaporator 3, and may typically be maintained at 15 psia. This greatly improves the efficiency of the refrigeration system. the evaporator with the first unit cools the condenser of the second unit). If the side port of the main compressor cannot handle the mass flow of vapor, a two stage compression system, with the interstage pressure being the pressure of the intermediate slurry tank is an optional embodiment. In a cascade refrigeration system, two or more vapor-compression cycles with different refrigerants are used. A single stage, on a call for cooling, will operate at 100% of capacity while the two-stage and the modulating systems have stages based on demand. The inlet 61 may be tangential to the vertical curvature of the slurry tank wall. A typical system (evaporator, compressor, gas cooler, expansion valve) is the reference system … The gas transmission coefficient of the compressor is greatly reduced, and when the compression ratio is ≥20, = 0. The longer time this pressure transition exists, the larger the refrigerant particles become. The evaporator 3′ has an inlet 6′ and an outlet 8′. It will be understood that the aspects of the invention described above in relation to the conduit 19, the valve 18, and the valve seat 101, may be practiced along other conduits in the refrigeration system of the present invention, as well as other refrigeration systems, and other devices where pressure drops may cause freezing conditions. Sealing between the ball and the body is accomplished by two ring shaped seats located in the valve body on opposite sides (inlet and outlet) of the cavity for engagement with the ball and which have openings defining a portion of the inlet and outlet passages respectively. For the present invention it is desirable to keep the refrigerant particles small to increase the surface area to mass ratio, for refrigeration efficiency as well as improved suspension in slurry. Multi-stage refrigeration systems are an area of growing industrial importance in large plants. Therefore, the two-stage compression refrigeration system with one throttling is adopted in practice. JOHN BEAN TECHNOLOGIES AB, SWEDEN, Free format text: This upward slope minimizes the amount of fluid in contact with the valve 18 when it is shut, which in turn minimizes the risks of the valve 18 freezing shut. A seat for a ball valve having a housing formed with a fluid passageway extending therethrough, a ball disposed within the housing and in registry with the fluid passage way and a handle for rotating the ball, said seat comprising: a spheroid portion shaped to closely overlie a portion of the ball presented to the fluid passageway of the housing; opening formed in the spheroid portion of the seat; the opening shaped for allowing flow to initiate through a valve when a valve handle has a rotational location of equal to or greater than twenty percent open, and preventing flow through the valve when the valve handle is at a rotational location less than twenty percent open. This could be accomplished by having no expansion in conduit 19. These readings can be used by the control system 28 to control the position of the valve 18 in the conduit 19 to control the flow of refrigerants into the intermediate slurry tank 37. The rotor 225 comprises openings such as holes 229, slot, or other shaped opening or openings. For example:-35 / + 35 °C system: evaporation temperature-35 °C, evaporation pressure (absolute pressure)0.093 MPA; condensation temperature + 35 °C, condensation pressure (absolute pressure)1.353 MPA; single-stage Cycle: Pressure Ratio 1.353 / 0.09314.55. Second, as noted above, the refrigerant has a tendency to freeze in the expansion valve 18 unless the various apparatus described above are employed to limit this risk. In another embodiment of this invention, multiple direct injection systems may be connected to the intermediate slurry tank 37. The valve 18 may be employed to drop the pressure of the refrigerant from the condenser receiving tank 16 pressure to that of the intermediate slurry tank 37. Referring to FIG. A two-stage compression refrigeration system operates with refrigerant-134a between the pressure limits of 1.4 and 0.10 MPa. Alternatively or in addition, the conduit 19 should be as straight as possible to avoid small areas of greater refrigerant residency, which may cause solid refrigerant to form partial or complete blockage of the conduit. This provides several advantages. 6 illustrates a cross sectional view of the direct injection system according to a further aspect of the present invention; FIG.

feed gas also assists in stirring the refrigerant. In another aspect of the invention, the compression system 10 of the present invention may be of various arrangements. The energy gains are greatest at sublimation temperatures well below the triple point. A two-stage refrigeration system includes an intermediate slurry tank for receiving and storing a refrigerant vapor and a slurry of solid sublimatable refrigerant particles in a liquid. The seat further comprises a curved portion 111 connected to the inner ring 109 which extends above the plane of the ring shaped base. A two stage cascade system has high temperature cycle and low temperature cycle. valve 18) to the intermediate slurry tank 37. Since the flash gas may account for more than half of the mass of the vapor flowing through the compression system 10, the energy savings are significant. FMC CORPORATION, ILLINOIS, Free format text: A two-stage cascade system uses two pairs of compressor plants, working individually with different refrigerants, connected among themselves so that evaporator one system is used to serve as the capacitor to a lower temperature of the system (i.e. Another feature of this aspect of the present invention is that the inlet 60 may end in a pipe expansion 63, as shown in FIG. In addition, the power consumption of a two-stage compression cycle is lower than that of the single-stage compression cycle. A refrigerator expansion line for a slurry of solid sublimatable particles in a liquid comprising: an expansion valve in fluid flow communication with a down stream portion of the supply conduit; a receptacle conduit in fluid flow communication with a down stream portion of the expansion valve; a receptacle in fluid flow communication with a down stream portion of the receptacle conduit; wherein the expansion valve drops the pressure of slurry flowing from the supply conduit to the receptacle conduit; and. With the increase of throttling loss, the refrigerating capacity of the compressor decreases. In another embodiment, an array of direct injectors of various flow rates could be controlled with solenoid type valves, thus eliminate the need for variable control motorized valves to control the flow of refrigerant into the intermediate slurry tank 37. More lubricating oil is taken out by superheated steam, which increases the load of oil separator, makes the oil vaporize and oil vapor enter the system in large quantity and affects the heat transfer effect of the heat exchanger. The proximal end of spindle 211 sealably extends beyond the proximal end of inner pipe 207. The main slurry tank sends the slurry back to the intermediate slurry tank 37, and sends the vapor to the compression system 10. The illustrated pin 233 is insertable into a cross hole formed in the socket 231 to secure the rotor 225 to socket 231. A refrigeration recirculation line as claimed in, 39. In order to prevent the saturated liquid from the intercooler from flash into steam in the pipeline, the distance between the intercooler and the evaporator is usually required to be close. Referring again to FIG. The compression system also receives vapor CO2 from the intermediate slurry vessel, compresses the vapor from the main slurry tank and intermediate slurry tank and send it to the condenser. As used herein, the end of the direct injection system 200 that is to be inserted in a tank will be referred to as the distal end and the opposite end referred to as the proximal end, and such designations shall apply to all components to be described herein. Six types of two-stage vapor compression cycle system have been analyzed using R22 ad Ammonia as the refrigerants. In a refrigeration system for use with a slurry of solid sublimatable particles in a liquid having a mixing tank with a first outlet, a first inlet, and a second inlet; an evaporator with an inlet and an outlet; a first conduit connecting the first mixing tank outlet to the inlet of the evaporator; a separator with a first inlet, first outlet, and second outlet; a second conduit connecting the evaporator outlet to the first separator inlet; the separator discharging directly to the mixing tank by the shared opening of the first separator outlet and the first mixing tank inlet; a compressor with an inlet and an outlet; a third conduit connecting the second outlet of the separator to the compressor inlet; a condenser having an inlet and outlet; a fourth conduit connecting the compressor outlet and the condenser inlet; a receiver having an inlet and outlet; a fifth conduit connecting the condenser outlet to the receiver inlet; a sixth conduit connecting the receiver outlet to the second inlet of the mixing tank; wherein the improvement comprises: the mixing tank having a second outlet for outlet of refrigerant vapor; the compressor having an intermediate pressure inlet for receiving refrigerant vapor; and.
