Abstract
The invention relates to a water cooling machine which has been specially designed to form part of air conditioning machines in water cooled refrigeration systems and to replace recovery towers. The invention consists of a gas cooling circuit for cooling the water, comprising a compressor (1), an axial fan (5) assisted condenser (4), a drum (6) and a tubular evaporator (11) which are assisted by standard parts such as pressure switches, filters, sights, solenoid valves and expansion valves. The tubular evaporator (11) acts as a heat exchanger between the gas corresponding to the above-mentioned cooling circuit and the water to be cooled, said evaporator (11) being connected to a storage tank (20) in which the cooled water from the evaporator is mixed with the water resulting from condensation in the air conditioning device that is coupled to the machine, such that the storage tank maintains the water at a temperature of between 7 and 12 ° C and the water is cooled in a closed circuit. In this way, the device overcomes the problems associated with recovery towers, such as noise pollution, water consumption and the proliferation of micro-organisms that are harmful to human health.

OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a una máquina enfriadora de agua, destinada a constituir un complemento de las máquinas de aire acondicionado en los equipos frigoríficos condensados por agua, suministrando precisamente el agua de condensación.The present invention relates to a water cooling machine, intended to constitute a complement to the air conditioning machines in the refrigerated water condensing equipment, supplying precisely the condensation water.
El objeto de la invención es eliminar, en este tipo de instalaciones, las torres de recuperación, que son sustituidas por la máquina de la invención, eliminándose paralelamente los problemas inherentes a dichas torres de recuperación, concretamente la contaminación acústica, el consumo de agua y la proliferación de microorganismos nocivos para la salud humana.The object of the invention is to eliminate, in this type of installation, the recovery towers, which are replaced by the machine of the invention, eliminating in parallel the problems inherent to said recovery towers, specifically noise pollution, water consumption and the proliferation of microorganisms harmful to human health.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Tal como acaba de decirse, en máquinas de aire acondicionado y en equipos frigoríficos condensados por agua, se utilizan torres de recuperación, generalmente ubicadas en los áticos de los edificios y consistentes en depósitos de agua que por medio de ventiladores, consiguen bajar la temperatura a un valor del orden de 3 a 5 grados, utilizándose este agua refrigerada, a través del correspondiente filtro, para alimentar a los
aparatos de aire acondicionado, o frigoríficos existentes en las distintas dependencias de tales edificios.As it has just been said, in air conditioning machines and refrigerated equipment condensed by water, recovery towers are used, usually located in the attics of buildings and consisting of water tanks that by means of fans, manage to lower the temperature to a value of the order of 3 to 5 degrees, using this chilled water, through the corresponding filter, to feed the air conditioners, or refrigerators existing in the different units of such buildings.
Estas torres de recuperación resultan funcionalmente ruidosas con la consecuente contaminación acústica, trabajan en circuito abierto, lo que supone un notable consumo de agua, y requieren de un mantenimiento prácticamente constante, especialmente para evitar al aparición de focos de legionella, lo que obliga a que tales depósitos deban estar permanentemente vigilados y tratados con la consecuente y negativa repercusión económica que ello supone.These recovery towers are functionally noisy with the consequent noise pollution, work in an open circuit, which means a remarkable consumption of water, and require a practically constant maintenance, especially to avoid the appearance of foci of legionella, which requires that such deposits must be permanently monitored and treated with the consequent and negative economic impact that this implies.
Como se deduce de lo anteriormente expuesto es deseable en estas instalaciones la eliminación de las citadas torres de recuperación al objeto de eliminar a su vez toda problemática que ellas tren consigo.As can be deduced from the above, it is desirable in these facilities the elimination of the aforementioned recovery towers in order to eliminate, in turn, any problems they have with them.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION

Para ello y de forma más concreta, la máquina presenta como una de sus características esenciales el que utiliza un circuito de refrigeración por gas para el enfriamiento del agua, en el que como elementos operativos generadores de ruido participan exclusivamente un compresor y un ventilador axial, determinantes de una contaminación acústica extraordinariamente más baja que la de las clásicas torres de recuperación.
De acuerdo con otra de las características de la invención el citado circuito de refrigeración, a través de un evaporador tubular, enfría agua en circuito cerrado, lo que por un lado elimina el clásico consumo y por otro lado la aisla de todo tipo de gérmenes en especial de los patológicos.For this, and more specifically, the machine presents as one of its essential characteristics the one that uses a gas cooling circuit for water cooling, in which as a noise-generating operating elements exclusively a compressor and an axial fan participate, determinants of an acoustic contamination extraordinarily lower than that of the classic recovery towers. According to another of the characteristics of the invention said cooling circuit, through a tubular evaporator, cools water in a closed circuit, which on the one hand eliminates the classic consumption and on the other hand isolates it from all types of germs in Pathological special.
En el citado evaporador tubular participan una pluralidad de tubos a través de los que circula el gas correspondiente al circuito de refrigeración, bañados por el agua que llega caliente a dicho evaporador y que sale fría, con el concurso de una bomba circuladora que envía el agua hacia un depósito de inercia, donde se realiza la mezcla del agua procedente de la condensación del aparato de aire acondicionado de que se trate, con la que procede de la enfriadora, controlándose la mezcla con una válvula que permite alcanzar una temperatura de consigna, para que el agua pueda ser utilizada nuevamente en la condensación.In the aforementioned tubular evaporator a plurality of tubes participate through which the gas corresponding to the refrigeration circuit circulates, bathed by the water that arrives hot to said evaporator and that leaves cold, with the help of a circulating pump that sends the water towards a tank of inertia, where the mixing of the water from the condensation of the air conditioner in question is carried out, with which it comes from the chiller, controlling the mixture with a valve that allows to reach a setpoint temperature, to that water can be used again in condensation.
Lógicamente la máquina enfriadora estará dotada de otros accesorios típicos para su correcto funcionamiento, tales como calderín, filtros, válvulas de expansión, termostatos, manómetros, termómetros, etc, como se verá mas adelante.Logically the cooling machine will be equipped with other typical accessories for its correct operation, such as boiler, filters, expansion valves, thermostats, pressure gauges, thermometers, etc., as will be seen later.
