Definitions
- the present invention generally relates to refrigerator appliances and more particularly to household refrigerator appliances having a skin condenser.
- Refrigerator appliances conventionally comprise a cabinet made up of an inner container and an outer container that define between them a cavity filled with a thermally insulating material like e.g. a polyurethane foam.
- the cabinet comprises a door that is pivotally assembled on one of its side walls.
- a standard refrigeration cycle includes four stages. First, a refrigerant fluid in a gaseous phase is compressed by a compressor to high pressure and high temperature. Second, the refrigerant fluid is made to flow through a condenser wherein it is cooled by heat exchange with ambient air and changes phase from gaseous to liquid. Third, the refrigerant fluid passes through an expansion device that reduces its pressure and temperature. The refrigerant fluid is then fed to an evaporator arranged in thermal contact with the inside of the cabinet where it evaporates thus absorbing heat from the cabinet cavity. The refrigerant fluid exiting the evaporator returns to the compressor and the cycle is repeated.
- the condenser is typically in the form of a plate on tube (PoT) or wire on tube (WoT) heat exchanger mounted on the back wall of the refrigerator cabinet and spaced apart from it by using e.g. brackets. Cooling may occur due to natural convection or by drawing or blowing air across the condenser typically by way of a fan.
- PoT plate on tube
- WoT wire on tube
- “skin condensers” are proposed. These condensers comprise tubes that are attached to or integrated into one or more of the cabinet walls.
- a serpentine tube is glued on a thermally conductive layer applied to the outer surface of the back wall of the refrigerator cabinet.
- An example of a skin condenser of this type is disclosed by WO2019/020175A1 . This configuration allows to increase thermal exchange with the environment surrounding the refrigerator appliance, because the tube is arranged outside the refrigerator cabinet.
- Document US2,145,776 discloses a refrigerator having a cabinet, a chamber to be cooled and a refrigerating system which includes an evaporator, a condenser and a compressor.
- the evaporator is positioned within the chamber, whilst the condenser and the compressor are both exteriorly positioned.
- the refrigerator further comprising a plurality of open troughs thermally associated with the condenser, means for collecting water dripping from the evaporator and means for conducting the water to the troughs.
- Document US6,363,736B1 discloses a condensate collection structure for collecting and evaporating liquid condensation from a refrigerator.
- the structure includes a bracket assembly attached to the refrigeration housing unit and supporting both a condenser tubing array and a removable condensate drain pan.
- the condenser tubing array extends within and adjacent the bottom of the condensate drain pan when the drain pan is attached to the bracket assembly.
- Document DD228036A1 discloses a condenser for refrigerators having heat-conductor plates of a width corresponding to the interval between the serpentine's pipes of the condenser. The plates are bent into troughs at alternate edges so as to fit a quarter of the way round pipes in heat-conductive contact with them.
- Document US3,379,241 discloses a refrigerator condenser comprising a single continuous length of tubing formed into a series of equal parallel straight lengths, lying in the same plane and interconnected by reverse bends. The parallel straight lengths are fitted into similarly spaced part-circular grooves formed in a sheet metal plate. A series of U-shaped channel members, each having a part-circular groove extending along the length of its web, is spot-welded to the plate.
- Document US2007/0023170A1 discloses a domestic refrigerator condenser which comprises a bent tube in which the cooling circuit medium can be condensed and a carrier plate to which the tube is secured.
- the tube is made of steel, whilst the plate consists of an aluminum sheet.
- the technical problem underlying and solved by the present invention is therefore to provide a refrigerator appliance with a skin condenser that allows to overcome the drawbacks mentioned above with reference to the prior art.
- the refrigerator appliance of the invention comprises an evaporator that forms with a compressor and a condenser a closed cooling circuit wherein a refrigerant fluid is made to circulate.
- the condenser is a configured as a skin condenser and comprises a serpentine tube associated with a thermally conductive layer. Thanks to this feature, not only can the outer size of the refrigerator appliance be reduced and manufacturing costs be lowered, but the size of the refrigerator cavity can be enlarged to achieve a larger storing capacity for the benefit of the users.
- the thermally conductive layer forms the whole back wall of the outer casing of the cabinet of the refrigerator appliance. Hence, together with the other cabinet walls the skin condenser allows to contain the insulating foam during the foaming process.
- the thermally conductive layer is made up of a plurality of plates arranged such that a tail portion of a first plate is superimposed to and connected with a front portion of a subsequent, second plate.
- the straight portions of the serpentine tube are clinched between the two plates at their connection interface, thus allowing to achieve a good surface contact with the thermally conductive layer as a whole. This results in an effective thermal exchange with the outer environment and hence in a good thermal performance of the skin condenser. Energy consumption of the refrigerator appliance is thus effectively reduced compared to prior art appliances of a similar size.
- the defrost water drain pipe typically used to drain defrost water from the evaporator is advantageously arranged in thermal exchange contact with the skin condenser. Thanks to this configuration, heat extracted from the refrigeration fluid can effectively be used to prevent unwanted ice clogging of defrost water inside the pipe and to effectively warm up defrost water, allowing a quicker evaporation. This also allows to use a smaller tray to collect defrost water.
- phase-change materials may effectively be associated with the skin condenser to promote thermal exchange and increase energy efficiency.
- Phase change materials may be applied to the thermally conductive layer in the form of a coating of the plates or as blocks/pouches attached thereto, and combinations thereof.
- a refrigerator appliance according to the invention is generally indicated by reference number 100.
- the refrigerator appliance 100 is shown with reference to a three-dimensional coordinate system.
- a first axis X and a second axis Y that are mutually perpendicular define a horizontal plane, while a third axis Z, perpendicular to said horizontal plane, defines a vertical axis along which the force of gravity acts.
- the refrigerator appliance 100 hereinafter also referred to as refrigerator only, comprises a cabinet 110 whose cavity is configured to store food items.
- the appliance shown in the drawings is e.g. a "bottom mount" refrigerator, where a refrigerator compartment 111 is formed above a freezer compartment 112 in a vertical direction and are separated from each other by a mullion 113.
- An evaporator is provided to cool the refrigerator compartment 111 and the freezer compartment 112 at cooling temperatures typically comprised between 1°C and 10°C and between -18°C and -28°C, respectively.
- the cabinet 110 comprises an inner casing or liner 114 e.g. made of a polymeric material, where the refrigerator compartment 111 and the freezer compartment 112 are formed, and an outer casing 115.
- the outer casing 115 is spaced apart from the inner casing 114 so as to define a cavity filled with a thermally insulating material such as e.g. polyurethane foam.
- the outer casing 115 typically has a parallelepiped shape and comprises a pair of spaced apart side walls 116a, 116b, a top wall 117, a bottom wall 118 and a back wall 119. These walls may e.g. be made of sheet metal or a plastic material.
- the refrigerator compartment 111 and the freezer compartment 112 are selectively accessible through respective doors 120, 121.
- the refrigerator appliance 100 comprises an evaporator, such as e.g. an evaporator 130 that is arranged e.g. below the mullion 113, allowing to cool air which is supplied to the refrigerator compartment 111 and the freezer compartment 112, respectively, via a fan and a damper (not shown).
- the evaporator 130 is part of a closed cooling circuit of the refrigerator appliance 100 also comprising a compressor 140 and a condenser 150, wherein a refrigerant fluid is made to circulate.
- the refrigerant fluid fills the closed cooling circuit.
- the compressor 140 is operated by a control unit (not shown) of the refrigerator appliance 100, and makes the refrigerant fluid to circulate through the condenser 150 and then through the evaporator 130.
- the refrigerant fluid When flowing through the condenser 150, the refrigerant fluid is cooled down and changes phase from the gaseous to the liquid one while releasing heat that is dissipated by the condenser 150.
- the refrigerant fluid evaporates, thus subtracting heat from surrounding air, which is cooled and can be supplied to the refrigerator and freezer compartments.
- the condenser 150 is a configured as a skin condenser and comprises a serpentine tube 160 associated with a thermally conductive layer 170 made of e.g. steel or aluminum.
- the thermally conductive layer 170 forms at least a portion of at least one of the walls of the outer casing 115 of the cabinet 110.
- the thermally conductive layer 170 forms the whole back wall 119 of the outer casing 115, which advantageously allows to use the skin condenser 150 together with the other walls of the outer casing to contain the insulating foam during the foaming process.
- the serpentine tube 160 runs along the whole thermally conductive layer 170 so as to maximize thermal exchange with the outer environment.
- the thermally conductive layer 170 is made up of a plurality of plates 171, 172, etc., arranged such that a tail portion of a first plate, e.g. plate 171, is superimposed to and connected with a front portion of a subsequent, second plate, e.g. plate 172.
- every one of the straight portions 161, 162, etc., of the serpentine tube 160 is clinched between a pair of plates of the thermally conductive layer 170, where the tail portion of a plate is superimposed to and connected with the front portion of a subsequent plate. Thanks to this configuration, a good surface contact is achieved between the straight portions of the serpentine tube 160 and the thermally conductive layer 170 as a whole, which results in an effective thermal exchange with the outer environment and hence in a good thermal performance of the skin condenser 150.
- the straight portions 161, 162, etc. of the serpentine tube 160 run horizontally and the thermally conductive layer 170 is made up of a plurality of rectangular plates arranged with their longer sides in the horizontal direction.
- the thermally conductive layer 170 forms at least a portion of at least one of the walls of the outer casing 115 of the cabinet 110, and preferably the whole wall.
- Anchoring means are foreseen to allow connection between such portion or such wall to the neighboring walls of the outer casing 115.
- flap-shaped portions may e.g. be formed on opposite sides of the plates 171, 172, etc. forming the thermally conductive layer 170.
- Equivalent assembly means may be used as well. For instance flap-shaped portions might be formed on the side walls 116a, 116b, on the top wall 117 and on the bottom wall 118.
- a water drain pipe 180 typically used to drain condensation water from the evaporator 130 is advantageously arranged in thermal exchange contact with the skin condenser 150.
- the drain pipe 180 may be arranged in direct contact with the thermally conductive layer 170 or slightly spaced apart from it, so that it is protected by a small amount of insulating foam.
- heat extracted from the refrigeration fluid can effectively be used to prevent unwanted ice clogging of defrost water inside the pipe and to effectively warm up defrost water, allowing a quicker evaporation throughout its path to a pan 190 typically arranged close to the compressor 140 in a machine compartment of the refrigerator appliance 100.
- the defrost water pipe 180 may advantageously have a serpentine shape. This allows to exploit the thermal exchange with the skin condenser 150 to make condensation water to evaporate even before reaching the pan 190.
- the pan 190 may advantageously be arranged on the compressor 140, as schematically shown in figure 3 , so as to exploit the thermal energy resulting from the operation of the compressor motor as a further means to evaporate condensation water.
- phase-change materials may effectively be used in combination with the skin condenser 150 described above to promote thermal exchange and increase energy efficiency.
- phase change materials are substances having a high heat of fusion which are capable of storing and releasing large amounts of thermal energy when melting and solidifying. Heat is absorbed or released when the material changes from solid to liquid and vice versa.
- phase change materials behave like sensible heat storage means, as their temperature rises when they absorb heat.
- PCM materials reach the temperature at which they change phase, e.g. their melting temperature, they absorb large amounts of heat at an almost constant temperature.
- a PCM material continues to absorb heat without a significant rise in temperature until phase change is complete, e.g. until all the material is transformed from the solid phase to the liquid phase.
- PCM materials may be applied to the thermally conductive layer 170 in the form of blocks/pouches 200 attached thereto between subsequent condenser coils 161, 162, as shown in figure 7 .
- Recessed portions may be formed in the plates 171, 172, etc., of the thermally conductive layer 170 so as to accommodate the blocks/pouches 200 and increase the contact surface in order to promote thermal exchange.
- PCM polystyrene resin
- e.g. paraffin wax which has a melting temperature of about 40°C.
