Definitions

  • the invention relates to refrigeration. More particularly, the invention relates to beverage coolers.
  • FIG. 1 schematically shows transcritical vapor compression system 20 utilizing CO 2 as working fluid.
  • the system comprises a compressor 22, a gas cooler 24, an expansion device 26, and an evaporator 28.
  • the exemplary gas cooler and evaporator may each take the form of a refrigerant-to-air heat exchanger. Airflows across one or both of these heat exchangers may be forced. For example, one or more fans 30 and 32 may drive respective airflows 34 and 36 across the two heat exchangers.
  • a refrigerant flow path 40 includes a suction line extending from an outlet of the evaporator 28 to an inlet 42 of the compressor 22.
  • a discharge line extends from an outlet 44 of the compressor to an inlet of the gas cooler. Additional lines connect the gas cooler outlet to expansion device inlet and expansion device outlet to evaporator inlet.
  • An electronic expansion valve is usually used as the device 26 to control the high side pressure to optimize the COP of the CO 2 vapor compression system.
  • An electronic expansion valve typically comprises a stepper motor attached to a needle valve to vary the effective valve opening or flow capacity to a large number of possible positions (typically over one hundred). This provides good control of the high side pressure over a large range of operating conditions.
  • the opening of the valve is electronically controlled by a controller 50 to match the actual high side pressure to the desired set point.
  • the controller 50 is coupled to a sensor 52 for measuring the high side pressure.
  • FIG. 2 An example of such a system 60 is shown in FIG. 2.
  • the gas cooler 62 is split into first and second sections 64 and 66. Along the refrigerant flowpath 66, the first section 64 is upstream of the second section 66.
  • the sections 64 and 66 may be along a common air flowpath to receive a common airflow 68 (e.g., driven by a fan 70) or may be on separate air flowpaths (e.g., driven by separate fans).
  • the first section may be upstream/downstream of the second section.
  • Water condensed from the airflow 36 is collected by a collection system 80.
  • An exemplary system 80 includes a pan 82 to which the water is delivered. A portion of the first section 64 is positioned to be immersed in a water accumulation in the pan. Heating of the water by the first section 64 encourages evaporation of the water.
  • the condensate may preferably be exposed to a more downstream section of the heat rejection heat exchanger.
  • a bottle cooler system includes means for using atmospheric water condensate from the evaporator to draw heat from the condenser.
  • FIG. 1 is a schematic view of a prior art refrigeration system.
  • FIG. 2 is a schematic view of another prior art refrigeration system.
  • FIG. 3 is a schematic view of an inventive refrigeration system.
  • FIG. 4 is a side schematic view of a display case bottle cooler including a refrigeration and air management cassette.
  • FIG. 5 is a view of a refrigeration and air management cassette.
  • FIG. 6 is a partial side schematic view of an alternative cassette. '
  • FIG. 7 is a partial side schematic view of an alternative cassette.
  • FIG. 8 is a partial side schematic view of an alternative cassette.
  • FIG. 3 shows a system 100 having a compressor 22, expansion device 26, and heat absorption heat exchanger (evaporator) 28. These may be similar to corresponding components of the systems of FIGS 1 and 2. For illustration, the control and sensor components are hidden.
  • the gas cooler 102 is split into first and second sections 104 and 106. Along the refrigerant flowpath 66, the first section 104 is upstream of the second section 106.
  • the sections 104 and 106 may be along a common air flowpath to receive a common airflow 108 (e.g., driven by a fan 110) or may be on separate air flowpaths (e.g., driven by separate fans).
  • the first section 104 is upstream of the second sectionl06 with the fan 110 intervening.
  • An exemplary system 112 includes a pan 122 to which the water is delivered. A portion of the second section 106 is positioned to be immersed in a water accumulation in the pan 122. Heating of the water by the second section 64 may encourage evaporation of the water. Contrasted with the system of FIG. 2, the section of the gas cooler, which gives up heat to the condensate is relatively downstream along the refrigerant flow path (e.g., in the cooler half or quarter of the temperature drop prior to the expansion device). This is intended to reduce the refrigerant temperature as much as possible by exposing the coldest refrigerant to the condensate.
  • FIG. 4 shows an exemplary cooler 200 having a removable cassette 202 containing the refrigerant and air handling systems.
  • the exemplary cassette 202 is mounted in a compartment of a base 204 of a housing.
  • the housing has an interior volume 206 between left and right side walls, a rear wall/duct 216, a top wall/duct 218, a front door 220, and the base compartment.
  • the interior contains a vertical array of shelves 222 holding beverage containers 224.
  • IUUZ4 ""' ⁇ me exeiriplalryT'aSsette 202 draws the air flow 108 through a front grille in the base 224 and discharges the air flow 108 from a rear of the base.
  • the cassette may be extractable through the base front by removing or opening the grille.
  • the exemplary cassette drives the air flow 36 on a recirculating flow path through the interior 206 via the rear duct 210 and top duct 218.
  • FIG. 5 shows further details of an exemplary cassette 202.
  • the heat exchanger 28 is positioned in a well 240 defined by an insulated wall 242.
  • the heat exchanger 28 is shown positioned mostly in an upper rear quadrant of the cassette and oriented to pass the air flow 36 generally rearwardly, with an upturn after exiting the heat exchanger so as to discharge from a rear portion o the cassette upper end.
  • a drain 250 may extend through a bottom of the wall 242 to pass water condensed from the flow 36 to the drain pan 122.
  • a water accumulation 254 is shown in the pan 122.
  • the pan 122 is along an air duct 256 passing the flow 108 downstream of the heat exchanger first section 104.
  • the heat exchanger second section 106 is positioned to be at least partially immersed in the accumulation 254. Exposure of the accumulation 254 to the immersed second section 106 and to the heated air in the flow 108 may encourage evaporation.
  • the second section is divided into a first portion normally above the accumulation and in the airflow 108 and a second portion normally immersed.
  • the refrigerant flow path may pass generally downstream along the air flow 108 through the first portion and then pass into the second portion before proceeding to the expansion device.
  • FIG. 5 arrangement is consistent with a basic reengineering of a baseline cassette having a single heat rejection heat exchanger located where the first section 104 is and nothing where the second section 106 is. It is also consistent with a reengineering of a split system where the hotter section is in that latter position.
  • the illustrated configuration has the disadvantage that the cooler section is downstream of the hotter section along the air flow path. Accordingly, it may be desirable to reverse the air flow to become back-to-front. A portion of this back-to-front air flow could be directed to flow over the cooler door window to avoid window fogging.
  • An alternative implementation might eliminate the physical separateness of the first section 104.
  • FIG. 5 One example would be to only have a single heat rejecting heat exchanger unit positioned as represented by the second section 106 in FIG. 5. The immersed portion of that exchanger unit could serve the role of the second section 106 while the exposed portion could serve the role of the first section 104 (see FIG. 6 below). Another simple variation could involve heat exchanger positioning so that water dripping from the drain flows over a leading portion of the heat exchanger (i.e., at the upstream end of the warm air flow).
  • Various implementations may further maximize heat transfer via a counterflow exchange of condensate water and the refrigerant. This counterflow may be the exclusive method of heat exchange between the condensate and the refrigerant, or may supplement pan immersion or another mechanism.
  • FIG. 1 This counterflow may be the exclusive method of heat exchange between the condensate and the refrigerant, or may supplement pan immersion or another mechanism.
  • FIG. 6 shows such a system, wherein the drain 250 having an outlet 260.
  • a length 262 of the refrigerant line extends upward to the outlet.
  • the length 262 is positioned to guide/wick droplets of water from the outlet 260 downwardly along the length 262 to the drain pan.
  • a more upstream (along the refrigerant flow path) length 264 (or portion of the heat rejection heat exchanger) may be immersed in the water 254in the pan.
  • a yet more upstream portion 270 may be in the air flow [0030]
  • a relatively small downstream section of the gas cooler may run through/in the drain pan 122.
  • a smaller yet more downstream portion may run up into the to evaporator drain in a counterflow heat exchange (both along its length and/or merely a two step counterflow in combination with the portion in the pan).
  • the drain 250 is replaced by a more convoluted drain 300.
  • the drain 300 has an upwardly directed U-portion 302 defining a water trap containing a water slug 304.
  • the drain 300 and slug 304 may prevent air leakage between the hot and cold air flows and might be used independently in place of the simpler drain 250.
  • the slug is continuously replenished by condensate flowing into the drain 300 and continuously discharges condensate down toward the pan 122.
  • a portion 306 of the refrigerant line extends from a remainder of the second section 106 and through the drain 300.
  • the expansion device (not shown) may be positioned between the downstream end of the line portion 306 and the evaporator 28.
  • refrigerant flowing through the line portion 306 is in counterflow heat exchange with the condensate flowing through the drain 300.
  • the line portion 306 may enter the drain outlet 308 and/or exit the drain inlet 310 and more closely follow the path of the drain.
  • FIG. 8 shows an alternate drain 320 having an outlet 322.
  • a length 324 of the refrigerant line extends upward to the outlet.
  • the length 324 is positioned to guide/wick droplets of water from the outlet 322 downwardly along the length 324 to the drain pan. With refrigerant flowing upward through the length 324, the refrigerant and water are in counterflow heat exchange. A more upstream (along the refrigerant flow path) portion of the heat rejection heat exchanger may be immersed in the water in the pan.
  • the condensate could be delivered to air flow (e.g., 108) just prior to its passing over the last portion of the heat rejecting heat exchanger (i.e., the gas cooler which would be a condenser if conditions were appropriate) so that the heat transfer is enhanced and hence the refrigerant temperature is reduced. This may be particularly effective in dry climates where evaporative cooling of the air flow is particularly relevant.
  • This condensate to air delivery could be done in several ways.
  • a wick could be placed upstream of the relevant section of the heat exchanger along the air flow.
  • a spray device could be similarly positioned to introduce the spray of condensate to the air flow.
  • Such a spray could also or alternatively directly contact the relevant heat exchanger portion to cool via evaporative or conventional cooling.
  • a wick could contact the heat exchanger to transport the water and provide conventional and/or evaporative cooling.
