PROVISION INTRODUCED IN AIR CONDITIONER.

Application field.

[001] This report deals with the detailed description accompanied by illustrative figures of a new model of air conditioner to be preferably mounted on walls, which features an energy saving and emergency system that works in direct current, this being a system free cooling or free cooling, which consists of the technique that explores the existence of temperature differences between environments (enthalpy) for the production of free cooling, that is, free cooling. This equipment is preferably intended to be used in containers or confined rooms that require a temperature-controlled environment, or for some heating, ventilation and air conditioning systems, in industrial applications and in some other specific applications.

[002] More precisely, the air conditioner, object of the present patent, is an air conditioner equipment with free cooling, or free cooling (free cooling) and with a filter system that provides filtered air through the incorporated Gore filter in the air conditioner, thus constituting a hybrid system where the free cooling system monitors the ambient temperature, and if it is favorable (less than the desired internal temperature) it is kept in primary operation and only when the ambient temperature is equal or higher than the desirable internal temperature, the air conditioner will be activated secondarily, in this way, being an equipment that provides savings in electricity for the final customer and also being maintenance free.

State of the art problems.

[003] Air conditioners similar to the proposal of this patent and currently known present a series of problems with the use of unsuitable and outdated manufacturing materials, such as fans that result in low efficiency and high energy consumption. In general, these air conditioners are deficient for the desired application, are unable to cool the entire area of operation and do not maintain the necessary temperature for the environment. The emergency systems are deficient because

Petition 870160043175, of 08/15/2016, p. 8/18

2/8 cannot remove the heat from the environment, resulting in a low capacity to act. These systems were designed to be used in places where there is no alternating current available in the place and to work only by circulating the air in the internal environment. In addition, the filtration systems of these current conditioners are deficient and sometimes complicated, since they require periodic maintenance, need a humidity controller in the internal environment of the container or in the room where they are used and have low filtering capacity.

[004] The current wall mounted air conditioners present emergency dc systems (dumper), however with a deficiency with regard to the materials used in the manufacture of them that are outdated. The emergency systems have low dissipation capacity, requiring periodic maintenance, as the filters used are of low efficiency which increases the humidity inside the container or room. Purpose of the invention.

[005] The Air Conditioner, object of the present patent, comes to solve the problems of the State of the Art, because it is a new and more current design, using materials of last generation manufacture, that is, fans with high performance and low energy consumption. The air flow has: lower inflation and upper return; correct conditioning for the intended application, with exchange with high sensitive heat factor and high air flow; and thus allows uniform cooling of the entire environment, maintaining greater control over the temperature in the internal environment.

[006] The air conditioner, object of the present patent, presents a high efficiency energy saving / emergency system, designed to work both in the absence of alternating current and in the existence of the same. This system is able to remove the heat dissipated in the internal environment, maintaining a temperature variation (delta) of + 10 ° C depending on the external temperature, being able to work without having to turn on the air conditioning refrigeration system. In addition, it has a high filtration system greater than 99% for particles of 0.3 pm with 1 cm / s frontal speed, tested according to Method EN1822: 2011, no

Petition 870160043175, of 08/15/2016, p. 9/18

3/8 requires humidity control devices, does not require maintenance and still has a high capacity to remove sensitive heat, since it has filter elements class E11 and IP66 protection.
