Definitions

  • the present invention relates to a refrigerated sales cabinet.
  • refrigerated sales cabinets in which the compressor of a vapor compression cycle is arranged at or within the cabinet body.
  • a refrigerant circulates through the elements of the vapor compression cycle, in particular through the compressor, a condenser, an expansion device and an evaporator.
  • the refrigerant can be flammable or non-flammable.
  • refrigerant especially a flammable refrigerant such as R290
  • Some refrigerants, including flammable refrigerants have the tendency to sink down to the bottom of the refrigerated sales cabinet, when having exited the vapor compression cycle through a leak. This is dangerous, since if the amount of leaked refrigerant which collects at the bottom of the refrigerated sales cabinet exceeds a certain threshold, there is a high risk of fire or even an explosion, if such leaked refrigerant is somehow ignited.
  • JP S59 167672 A shows a refrigerator comprising a first passage communicating with a contamination chamber at a part of a corner, and a second passage communicating with the first passage at an upper portion of the machine chamber.
  • This document shows all the features of claim 1 except for the following ones: Instead of a refrigerated sales cabinet, it shows a household refrigerator.
  • the decorative cover/ledge is not mounted on the rear face of the rear wall of the refrigerated cabinet, but rather to the rear ends of the ridge portions forming the rear ends of the side walls of the cabinet body.
  • the pressure line extends between the drainage contentor for forcibly evaporating the deep frost water accumulated in the deep frost water evaporating dish and the compressor. The pressure line does not extend behind the rear wall of the cabinet body and is not covered, at least partially, by a ledge.
  • DE 199 06 742 A1 shows a device having a cold chamber for accommodating cold goods, whereby heat is extracted using an evaporator from a first air flow produced to cool the goods.
  • a fan produces a second air flow that is passed by a liquefier and a compressor.
  • the liquefier is mounted on a rear wall of the refrigerator and extends essentially over the entire lateral extent of the refrigerator.
  • a refrigerated sales cabinet according to the invention comprises the features of independent claim 1.
  • the inventors of the present patent invention have understood that the risk of refrigerant leaking out of the vapor compression cycle is particularly high at or in the vicinity of the compressor, since the refrigerant within the compressor or leaving the compressor through the pressure line is at a high pressure level, and since the refrigerant conduit at the compressor typically comprises bent and welded portions and/or manifolds, which are susceptible for forming leaks therein.
  • the compressor is arranged at the bottom of the refrigerated sales cabinet, and therefore the bottom of the refrigerated sales cabinet is typically the area where leaks are formed.
  • the risk that leaked flammable refrigerant collects at the bottom of the refrigerated sales cabinet, particularly within the compressor compartment, and constitutes a considerable risk of fire and explosion, can be considerably reduced or even fully avoided.
  • leaked refrigerant can be reliably evacuated from the compressor compartment, which can also be called machine room. It is reliably avoided that such leaked refrigerant will collect in the bottom portion of the refrigerated sales cabinet, particularly in the compressor compartment, where it would constitute a risk of fire or explosion.
  • the refrigerated sales cabinet ensures that the refrigerant concentration at the bottom of the refrigerated sales cabinet, particularly within the compressor compartment will stay below the acceptable threshold stipulated by the typical regulations, including the European regulation EN60335-2-89.
  • refrigerants including typical flammable refrigerants such as R290 have the tendency to sink down to the bottom of the refrigerated sales cabinet, when having exited the vapor compression cycle through a leak, is that they are heavier than air, particularly have a higher density than air. Therefore they tend to collect in the lowermost portion of the refrigerated sales cabinet, particularly in the compressor compartment.
  • the gas which is contained within the compressor compartment typically is air which can be mixed with leaked gaseous refrigerant, which is undesirable. Therefore, the expression "gas, including leaked refrigerant" is used to specify the gas or gas - leaked refrigerant mixture within the compressor compartment.
  • the diameter or cross-sectional area of the riser conduit should be large enough such that it provides a comparably low flow resistance.
  • the refrigerant sales cabinet is of the front access type and can be equipped with or without doors at its front access portion.
  • a suitable number of shelves on which the goods to be presented can be placed and supported can be provided within the refrigerated sales space.
  • the cabinet body typically provides a refrigerated sales space for storing goods to be presented therein.
  • the compressor compartment is typically located at or in a rear part of a bottom portion of the cabinet body.
  • the riser conduit extends substantially in a vertical direction, which provides for a particularly efficient discharge of the gas, particularly the leaked refrigerant from the compressor compartment.
  • the outlet port of the riser conduit is located behind the rear wall of the cabinet body at a height between a middle portion of the rear wall and the roof portion, particularly at a height of 1.50 to 2.00 meters above the floor on which the refrigerated sales cabinet stands.
  • the outlet port is located at such height, the gas, including the leaked refrigerant exiting such outlet port will mix sufficiently with ambient air before sinking down to a bottom portion outside the refrigerated sales cabinet.
  • the riser conduit can be located at, within or behind the rear wall of the refrigerated sales cabinet.
  • At least a portion of the riser conduit is formed by the rear face of the rear wall of the cabinet body and a ledge, particularly a U-shaped ledge mounted on the rear face of the real wall of the refrigerated sales cabinet.
  • the gas, particularly the leaked refrigerant can be discharged efficiently into an upper direction.
  • the outlet port of the riser conduit can be arranged at or behind the rear wall of the refrigerated sales cabinet so as to discharge the gas, including the leaked refrigerant, to an environment behind the refrigerated sales cabinet, such that the gas, in particularly the leaked refrigerant exiting such outlet port will mix with ambient air behind the rear wall of the cabinet body.
  • the riser conduit is formed as a fanless riser conduit.
  • the compressor compartment is arranged at or in the rear wall of the cabinet body.
  • the compressor compartment can enclose at least one compressor and separate the interior of the compressor compartment in which the at least one compressor is arranged, from the refrigerated sales space and/or from the outside of the refrigerated sales cabinet.
  • the rear side of the compressor compartment can be formed by a removable rear cover closing an opening within the rear wall of the cabinet body.
  • Such compressor compartment provides for a compact design and a safe and reliable operation of the refrigerated sales cabinet while maximising the size of the available refrigerated sales space. It has been found out, that such compressor compartments often are not fully not gas-tight such that gas, particularly refrigerant, can flow out of the same through existing gaps and can accumulate on the floor on which the refrigerated sales cabinet stands, where it would form a risk of fire or explosion. This risk, however, is significantly reduced or even fully avoided by the provision of a riser conduit according to the exemplary embodiment of the invention.
  • the refrigerated sales cabinet can be formed as semi-plug-in cabinet; wherein the vapor compression cycle comprises at least one compressor, at least one condenser, an expansion device and an evaporator and refrigerant conduits interconnecting these elements and circulating a refrigerant therethrough; and wherein the at least one condenser is formed as a heat exchanger transferring heat from the compressed hot refrigerant to a brine.
  • Such brine typically comprises brine conduits arranged at or on top of the roof portion of the refrigerated sales cabinet.
  • Such semi-plug-in cabinet does not have condenser fans which could contribute to mixing the gas, particularly the leaked refrigerant discharged from the compressor compartment.
  • the refrigerated sales cabinet can also be formed as a plug-in cabinet; wherein the vapor compression cycle comprises at least one compressor, at least one condenser, an expansion device and an evaporator and refrigerant conduits interconnecting these elements and circulating a refrigerant therethrough; and wherein the at least one condenser is formed as a heat exchanger transferring heat from the compressed hot refrigerant to ambient air.
  • the at least one condenser can be equipped with one or more condenser fans.
  • the gas, particularly the leaked refrigerant discharged from the compressor compartment can be mixed particularly efficiently with ambient air at or above the roof portion of the refrigerated sales cabinet.
  • the at least one condenser is arranged at or on top of a roof portion of the cabinet body.
  • the vapor compression cycle further comprises a pressure line extending between the at least one compressor and the at least one condenser.
  • the pressure line extends behind the rear wall of the cabinet body and is covered, at least partially, by a ledge, particularly a U-shaped ledge, mounted on the rear face of the real wall of the refrigerated sales cabinet, seen from behind.
  • ledge protects the pressure line, for example during transport of the refrigerated sales cabinet.
  • the interior space of the ledge enclosed by the rear face of the rear wall of the cabinet body and the inner surfaces of the ledge and which is not occupied by the pressure line, forms the riser conduit.
  • the cross section of such interior space can be in the range of 2 to 8 cm 2 .
  • the interior space of the ledge which is provided for protecting the pressure line from behind can be used as riser conduit or at least as part of the riser conduit.
  • the cross-sectional area of the riser conduit can be in the range of 2 to 8 cm 2 providing for an efficient discharge of a gas, particularly the leaked refrigerant from within the compressor compartment.
  • the riser conduit can be formed separately from the pressure line, for example as a separate vertical riser conduit mounted to the rear face of the rear wall of the cabinet body.

  • the refrigerated sales space 6 formed in the interior of the cabinet body 4 is enclosed by a bottom plate, a particularly perforated rear wall and a ceiling plate.
  • a cooling air cycle circulates through the intermediate spaces between the bottom plate of the refrigerated sales space 6 and the bottom portion of the cabinet body 4, between the rear wall of the refrigerated sales space 6 and the rear wall 12 of the cabinet body 4 and between the ceiling plate of the refrigerated sales space 6 and the roof portion of the cabinet body 4.
  • At least one evaporator 30 can be arranged which is shown in Fig. 3 .
