Definitions
- the invention relates to a serving counter for displaying refrigerated products in a display space thereof, comprising a display shelf that bounds the display space on a bottom side, which display shelf is configured for supporting the products to be displayed on a supporting surface thereof, a first refrigeration unit configured for supplying cooled gas to the display space via a wall of the display space and a second refrigeration unit configured for cooling the supporting surface, wherein the second refrigeration unit comprises a refrigerating element for cooling the supporting surface in a manner distributed over the display shelf.
- Serving counters are used in supermarkets and cheese stores, among other places, for the refrigerated display of products.
- the refrigerated products are to that end placed in a display space that is freely accessible to consumers and/or the storekeeper without these persons having to open and close a door or the like, for example, which gives access to the display space.
- the products are generally kept at a temperature ranging between -1 °C and + 4.4 °C.
- the display space of known serving counters is mainly bounded by a display shelf at the bottom side for supporting the products to be displayed thereon.
- a refrigeration unit is provided for blowing a cooled gas, for example air, into the display space, between the products present therein, via a side wall of the display space, and the display shelf is cooled.
- the refrigerating element comprises a first refrigerating part and a second refrigerating part, wherein the second refrigerating part is configured for cooling the supporting surface in a portion of the display shelf remote from the wall and the second refrigerating part is configured for realising a larger refrigeration capacity of the supporting surface than the first refrigerating part, wherein the first refrigerating part is configured for cooling the supporting surface in a portion of the display shelf adjacent to the wall.
- the invention is based on the insight that a relatively low temperature of the cooled gas to be blown into the display space is needed in the known serving counters for maintaining a desired temperature of the products in the display space thereof so as to realise the desired temperature of the products that are in a manner distributed over the supporting surface of the display shelf in use. Because the refrigeration capacity of the supporting surface is greater in a portion of the display shelf remote from the wall than in a portion of the display shelf adjacent to the wall, it is possible to keep products present on the supporting surface of the portion of the display shelf remote from the wall within a desired temperature range while using a higher temperature of the gas to be blown into the display space.
- the use of a higher temperature for the gas to be blown in by the first refrigeration unit leads to a reduced energy consumption of the serving counter in comparison with the known serving counters.
- An additional advantage is that because of the greater refrigeration capacity, the display shelf can extend along a greater length from the wall while keeping the desired temperature of the products within the aforesaid range.
- a wall of the display space is understood to mean a wall that bounds the display space.
- the "refrigeration capacity” is understood to mean the amount of energy that can be withdrawn from the products present on the display shelf per unit time.
- a serving counter is understood to cover serving counters for keeping products at a temperature ranging between -1 °C and + 4.4 °C as well as refrigerator and/or freezer cabinets for keeping products at a temperature ranging between -18 °C and + 4.4 °C.
- the second refrigerating part is provided at a smaller distance from the supporting surface than the first refrigerating part.
- the refrigeration capacity is increased in a practical manner as a result of an improved heat transfer between the second refrigerating part and the supporting surface.
- a ratio of a cooling surface area of the second refrigerating part to the portion remote from the wall of the supporting surface is greater than a ratio of a cooling surface area of the first refrigerating part to the portion of the supporting surface adjacent to the wall.
- the refrigerating element comprises an arrangement of pipes provided under the supporting surface for cooling the display shelf in a manner distributed over the display shelf, wherein a spacing between adjacent pipes is smaller in the second refrigerating part than in the first refrigerating part.
- the first refrigeration unit comprises an inlet extending in the wall, which inlet is configured for imparting a downward component into the display space to the gas to be blown into the display space for refrigerating the products that are present in the display space in use from above.
- gas guiding elements are provided at the inlets for guiding the gas to be supplied to the display space in a desired direction.
- the use of gas guiding elements is advantageous for realising a relatively precise distribution of the gas blown into the display space.
- an outlet is provided in the wall on the side of the inlet remote from the display shelf for discharging gas that is present in the display space from the display space.
- a fan is provided on the side of the outlet remote from the display space for discharging gas from the display space, wherein an axis of rotation of the fan extends substantially parallel to the wall.
- the outlet in the wall it is advantageous if the outlet is connected for fluid flow to the inlet via a first evaporator, wherein the first evaporator is configured for cooling the gas to be supplied to the display space through evaporation of a refrigerant. Connecting the two for fluid flow is advantageous for reducing the amount of energy that is needed by at least partially recirculating the cooled gas blown into the display space.
- the first evaporator is configured as a counterflow evaporator that is configured to provide a downward gas flow of the cooled gas to be supplied to the display space via the inlet and an upward flow of refrigerant present in the first evaporator.
- a counterflow evaporator is advantageous for realising a compact first refrigeration unit.
- the first evaporator is connected for fluid flow to a first heat exchanger, wherein the first heat exchanger is provided upstream of the first evaporator and the first heat exchanger is configured for cooling gas to be supplied to the display space via the inlet after the gas to be supplied has passed through the first evaporator.
- the first heat exchanger upstream, a relatively strong cooling of the gas to be supplied to the display space can be obtained before said gas is supplied to the display space via the inlet, wherein the gas cooled by the first heat exchanger is cooled by the first evaporator after being discharged from the display space.
- Such an embodiment is advantageous for realising a relatively large refrigeration capacity in a relatively compact construction.
- the refrigerating element is connected for fluid flow to an evaporator for evaporating a refrigerant that is provided downstream of the refrigerating element, which evaporator is formed by a second evaporator.
- an evaporator for evaporating a refrigerant that is provided downstream of the refrigerating element, which evaporator is formed by a second evaporator.
- the second evaporator is formed by the first evaporator.
- the fact that the second evaporator is formed by the first evaporator makes it possible to realise a larger refrigeration capacity in the first refrigeration unit.
- a heating device which comprises a second heat exchanger that can be connected for fluid flow to the refrigerating element and/or the first heat exchanger, wherein the second heat exchanger is configured for heating refrigerant present in the second heat exchanger by heat transfer.
- This heating device is advantageous with a view to heating the refrigerating element of the first heat exchanger, for example for removing or at least reducing any icing in the serving counter.
- This heating device can advantageously be used in a refrigerator or freezer cabinet.
- Refrigerator or freezer cabinets are used in supermarkets, among other places, for the refrigerated display of products.
- the refrigerated products are to that end placed in a display space that is accessible to consumers, who must to that end open a closing element, such as a door or the like, for example, which gives access to the display space.
- the products are generally kept at a temperature ranging between -18 °C and + 4.4 °C.
