Description

Refrigerating group

Object of the invention

The present invention relates to a group refrigerator, that is to a group in which a evaporator, a condenser and a compressor, working in circuit closed with a cooling fluid, to extract calories from a certain enclosure or cabin and generally provide them to outside environment, although they can also be deposited in a Different compartment

The object of the invention is to achieve a notable simplification and cost reduction in tasks of maintenance of the refrigeration group, especially when it has a breakdown that requires transport to the workshop.

Background of the invention

As is known, the refrigeration circuits are used with great profusion in cabinets and conservation tables for obtaining positive, average or negative temperature in bars, restaurants and other hospitality establishments, and in general in any practical case in the require to lower the ambient temperature to the desired temperature, within the container of the products to be refrigerated.

As is also known, a refrigerating group it is structured by the functional combination of a evaporator and a condenser, assisted by a compressor and mounted in closed circuit, passing through them a coolant, which accesses the virtually liquid evaporator at low temperature and pressure, where with the right temperature absorbs calories from said container, to then move on to through a compressor while the refrigerant in state high temperature and pressure gaseous reaches the condenser, where dissipates the heat of the carrier, to return to the Evaporator passing through the expansion device.

In any refrigerating group the evaporator will It is located inside the container of products to refrigerate, while the condenser is located outside it, obviously due to demands due to the need to dissipate the thermal energy captured by the evaporator, and without the latter being be affected by the existing temperature in the condenser and much less for the heat dissipated from it.

To achieve this relative positioning between evaporator and condenser, said elements, as well as the compressor, are related by pipes of greater or shorter length

While these refrigeration groups offer a optimal functionality from a theoretical point of view, in the practice and both in maintenance and repair, if The compressor, evaporator and / or condenser must be transferred to a workshop, to carry out its repair in due conditions, forces to cut the pipes of union between the elements of the system, with the consequent loss of the gas load, which implies a on the other hand an important economic cost, and on the other hand a problem of subsequent reliability, since technicians do not usually have the precise devices for the proper gas charge.

If the substitution of any of the pieces of it, also must cut and clean the tubes that interrelate the mechanism, welding them again with afterwards, after which the adjustment load of gas.

Description of the invention

The refrigerating group proposed by the invention, maintaining the classic components of a refrigeration circuit conventional, that is, maintaining the existence of an evaporator, a compressor, a condenser and its accessories, centers its characteristics in the fact that the aforementioned elements, that is evaporator, condenser and compressor, form a monobloc assembly mountable / detachable in a housing, so that in said single piece assembly the evaporator is oriented inwards of the container, while the condenser and the compressor remain oriented outwards, the first one being able to absorb the existing heat in the container, while the second dissipates Such heat out of it.

Preferably the evaporator will constitute the support of the elements of the refrigeration group, and said evaporator it will constitute a rectangular, attachable prismatic block tightly to a closet window or refrigerator table and attachable to said window by screwing or by any other appropriate conventional medium.

Description of the drawings

To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical implementation thereof, a single drawing is attached as an integral part of said description where Illustrative and non-limiting, a refrigeration group designed in accordance with the present invention, duly implanted in a refrigeration cabinet of
foods.

Preferred Embodiment of the Invention

In the figures outlined it has been referenced with (1) the container cabinet of the products to be refrigerated, with their corresponding access doors (2), closet that, according to the invention has a window on its upper base prismatic-rectangular (3), in which it remains perfectly fitted the evaporator (4) of the refrigeration system, fixed to the cabinet (1), for example by means of screws (5) nearby to its corners, so that said evaporator (4) in addition to fulfill its function as such, that is, as a means of absorbing heat inside the cabinet (1), tightly close the window or hole (3) in which it is implanted, and constitutes the physical support for a compressor (6) and a condenser (7) located outside the cabinet (2), the compressor (6) connected to the evaporator (4) through a conduit (8), the evaporator (4) with the capacitor (7) through a second conduit (9), and said condenser (7) with the compressor (6) through another conduction (10), to get the classic closed circuit.

In this way when removing the screws (5) previously mentioned, the evaporator (4), the compressor (6) and the capacitor (7) that constitute a single piece block or assembly, can be easily extracted from the corresponding furniture (1) to transport to a repair shop, without it being necessary effect the cutting of the tubes (8, 9 and 10), and consequently without that it is necessary to proceed later to the new fixation of the  themselves by welding and refilling the refrigerant fluid of circuit.

Claims (1)

1. Refrigerating unit, of the type of those constituted by the functional combination of an evaporator, a condenser and a compressor, connected in a closed circuit and through which a cooling fluid circulates, for absorption by the evaporator of the heat existing in a cabinet or refrigeration table of the products in question, characterized in that the evaporator materializes in a rectangular prismatic body or tending to this configuration, can be fitted tightly in a window operatively practiced in the wall of the container cabinet of the products to be cooled, said evaporator constituting , in addition to the closing element of the cabinet and the heat absorbing element generated by it, the physical support for the rest of the system elements, that is to say for the condenser and the compressor, so that all these elements constitute a monobloc assembly Detachable and replaceable.
