Title: Automatic system for evaporation of condensates

Description:
PURPOSE OF THE INVENTION 
     The Invention Patent to which this Report refers is intended to guarantee the exclusive use and ownership, throughout the country, of an automatic system of evaporation of the condensed liquid from air-conditioning and cooling units. 
     SCOPE OF THE INVENTION 
     The application of this invention is in the temperature and moisture exchange requirements, especially the evaporation of the liquid condensed during the air-conditioning process (F25), which arise in evaporators due to condensation. 
     This invention has two important purposes: firstly, it solves one of the most serious problems of domestic air-conditioning units, namely, the present need for complicated systems for the drainage of condensed liquids and, secondly, it significantly increases the heat efficiency of the unit and reduces power consumption. 
     BACKGROUND OF THE INVENTION 
     Nowadays, air-conditioning is the most complete process of ambient air treatment, involving the regulation of conditions in terms of temperature (heating or cooling), moisture and quality (renewal, filtering). 
     Over the last few years, the installation of air-conditioning units has become an essential requirement to achieve people&#39;s wellbeing in domestic, work and leisure environments. 
     The technique has advanced to such an extent that, nowadays, there are many low-price, high-performance, easily installed, noise-free air-conditioning systems on the market, but they all lack optimum systems for the elimination of the condensed liquids produced by the various units of which they are composed. 
     DESCRIPTION OF THE INVENTION 
     The invention consists of an adaptation to the external condenser unit, such that by installing the device for collecting the water condensed in the air-conditioning process, in which a simple electric pump for condensed liquids, a liquid level sensor and a set of small vertical pipes with atomizers at the end are installed, the condensed water is pumped over the external unit condenser and, thanks to the high temperature of the latter and the action of the equipment&#39;s fan, along with moisture exchange, the condensed liquid evaporates into the outside air, eliminating the need to include drainage pipes and/or containers for the collection of condensed liquids. 
    
    
     
       DESCRIPTION OF THE DIAGRAMS 
       To better understand the scope of this invention, we are going to describe it using the attached diagrams, which show a preferred design of the same, given as an example but not being the only possibility. 
         FIG. 1  shows a rear view of an external condenser unit with the invention installed and 
         FIG. 2  shows a side view of the same. 
     
    
    
     We can see that, in the diagrams, ( 1 ) represents the external condenser unit of an air-conditioning system, ( 2 ) the container for condensed liquids, ( 3 ) the liquid level sensor, ( 4 ) the pump, ( 5 ) the vertical pipes, ( 6 ) the atomizers and ( 7 ) the ventilation grille. 
     PREFERENTIAL FORMAT OF THE INVENTION 
     As you can see in the diagrams, the invention is located on the condenser unit of an air-conditioning system ( 1 ) and consists of a liquid level sensor ( 3 ), which detects the presence and level of liquid accumulated in the condensed liquid collection container ( 2 ) and, when the liquid in the container reaches a high enough level, activates the electric pump ( 4 ). The latter pumps the condensed liquid through the rear vertical pipes ( 5 ), attached to the external condenser unit ventilation grille, from which it is released through the atomizers ( 6 ) in the form of a fine spray. 
     The water released through the atomizers ( 6 ) falls directly on to the rear ventilation grille ( 7 ) of the condenser unit ( 1 ), where it quickly evaporates due both to the temperature of the condenser and the effect of the internal fan of the condenser, as well as the moisture of the outside air. 
     When the level of liquid in the condensed liquid collection container ( 2 ) drops, this is detected by the sensor, which turns off the pump and therefore the atomizers. 
     As you can see, the invention is as effective as it is simple and original. This set of elements: the sensor, the pump, the pipes and the atomizers are easy to handle and install and inexpensive. 
     With the invention, installation costs are also significantly reduced, since, as already mentioned, it makes it unnecessary to install drainage pipes, which often disfigure the facades of buildings. Energy costs are also reduced, since the water released on to the ventilation grille by the atomizers aids in the elimination of heat and improves the heat efficiency of the installation, as shown in the attached diagrams. 
     Apart from the basic invention, the patent also includes variations in detail, such that there may be variations in the type of level sensor and pump, the characteristics and quantity of pipes and atomizers, the size of the different parts of the system and, naturally, the material used.
