VESSEL COOLER DRY AIR FLU JO SYSTEM

SECTOR OF THE TECHNIQUE

The present invention has the task of presenting a refrigeration apparatus that guarantees the cooling of vessels to a temperature of approximately -10 ° C. What characterizes this invention is that the temperature of the vessels can be lowered without providing water and avoiding the creation of ice in them.

10 BACKGROUND OF THE INVENTION

The traditional refrigeration-freezing apparatus comprises a thermally insulated compartment and a refrigeration system, either by compression or by absorption, which is capable of keeping the products stored inside it at a temperature below 0 0 C. 15

In many establishments, these devices are used to cool dishes (glasses and jugs), for use in beer filling and maintenance at an ideal temperature.

20 Current appliances are introducing an undesirable effect. The continuous entry and exit of dishes to the insulated compartment allows the entry of hot air. When this air comes into contact with the chamber air, condensation is created in the dishes. When the insulated compartment is closed, said condensation quickly freezes in the dishes. Producing, this effect, presence of frozen water in the dishes.

Ice cold jars produce the following effects:

- It makes difficult the creation of adequate foam, which protects the liquid and prevents it from rusting, retaining and highlighting the aromas and taste.

- Water content (it is as if the waiter is asked to lower the beer with water).

30 - Form small blocks of ice that prevent savoring beer correctly.

- In the first "sips" what you are really drinking is ice water.

This claimed invention consists of two distinct parts. On the one hand, there is the condensing unit and on the other, there is the glass cooling unit, part in which the vessels for cooling are placed (Fig. 1).

The invention, as previously mentioned, has the task of lowering the temperature of the vessels without providing water and avoiding the creation of ice in them. For this, a compression refrigeration cycle has been created that consists in mechanically forcing the circulation of a refrigerant in a closed circuit divided into two zones: one of high pressure and another of low. In the low-pressure zone the refrigerant absorbs heat and in the high-pressure zone it expels it. In this way, the coolant (2) inside the evaporator (1) goes the refrigerant at low temperature so it absorbs heat from the air and cools the vessels. At this point, by means of fans the cycle of the air that is propelled to the vessels (3) is forced. Cold air comes out from the top of the unit. Through the outer holes (4) it comes out and goes up cooling the vessel, until it reaches the top (like hot air) and at this point it is collected by the central tube (5) and recirculated. In the same way, there are holes (6) on the outside of the vessel, which help the non-formation of condensation.

The peculiarity that characterizes our invention is that said evaporator (Fig. 3) has been created from cast aluminum with the design that best met our needs. Therefore, it has slots that circulate the air from the fans to the vessels. Each fan (7) drives the air up to two glasses, so we have six fans and, therefore, twelve holes with their respective methacrylate tubes (8) for each cup.

Said evaporator is placed in a double drawer perfectly thermally insulated. That is why we can affirm that the evaporator gives the dimensions and definitive shape to our element.

PREFERRED EMBODIMENT OF THE INVENTION

The invention is formed by several units. In the lower part is the technical zone or pump zone (compressor, condenser, capillary tube, electrical installation and programming of starts and stops), and in the zone glass cooler unit, the evaporator (1) is located with the coil ( 2), the fans (7) and the cup area.

This unit is formed in turn by two drawers: an outer drawer made of steel (9) and an inner drawer made of stainless steel (10) so that it is not oxidized by the cold produced inside the unit. Between the two drawers is the minimum thermal insulation of polyurethane foam (11).

Once these two drawers are assembled, when we introduce the aluminum evaporator (1) with the stainless steel coil (2) inside which the refrigerant gas goes

(propane 290) and the three fans (7) on each side of this, which are what they put in

air circulation

In the lower part of the unit, there is a drain (12) with evaporation tray, arranged to evaporate the water produced in the established defrosts. In addition, the refrigeration system control probe is located in the evaporator.

5

In the upper part, methacrylates (13) are placed, material that has behaved better and that breaks the thermal jump between the evaporator and the vessels, thus preventing ice from being produced. It is in this part where methacrylate tubes (8) are located where the vessels are placed and through which the hot air is collected.

10

On the other hand, the energy needed to charge the evaporators of the machine will be provided by evaporating refrigerant gas in a 3/8 ”copper tube, whose coil (2) is placed inside the evaporator (1). The size of the power of the compressor will depend on the capacity of vessels, in this case it has been determined that, by the mass of aluminum 15 used in the manufacture of the evaporators, a compressor of between 400-500 W is chosen, and It has empirically proved that it is adequate.

The exterior finish can be done both in sheet metal, as in pvc, etc., in which the signatures and logos established by the brand will be printed.
