Definitions

  • the invention generally relates to air conditioners and more particularly to a system for draining the condensate which is formed in these air conditioners during their operation.
  • the air conditioners to which the present invention relates are generally of two types, namely monobloc type air conditioners which are designed to be positioned and secured in openings provided in a wall or a window of the room to be conditioned and so communicating with the outside and air conditioners formed by separate units, so called "split" air conditioners, which comprise a unit intended to be placed inside of a room to be conditioned and a unit intended to be placed on the outside and connected to the inside unit by means of flexible tubes.
  • a condensate is formed therein, which is generally collected in a tray to be periodically emptied by the user. It is also known to drain the formed condensate through a drainage tube opening in the open air or connected to a sewer system.
  • Air conditioners of these types are also known, wherein the moisture condensed on the evaporator is collected in a tray and delivered by a pump through a tube to a spray nozzle arranged above the condenser.
  • the purpose of this arrangement is to return the condensate again to the condenser and to spray it directly thereon so that the condensate sprinkles the finned surface of the condenser and in so doing it promotes the heat exchange with resulting reduction of the condensation temperature.
  • GB-A-1.591.713 describes a condensate drainage system for air conditioners comprising a condensate collecting vessel, an atomizing nozzle, a condensate conduit connecting the condensate collecting vessel to the atomizing nozzle and a pump for pumping the condensate from the collecting vessel to the atomizing nozzle, said atomizing nozzle being arranged on the outside and being intended to atomize the condensate in the open air.
  • the condensate falls on the ground in liquid droplet form.
  • GB-A-2 126 695 describes a device for use in air conditioning equipment which controls the condensate level in a condensate collecting vessel in order to start a pump when the condensate is at a predetermined level and to stop said pump when the condensate is at the minimun level.
  • the object of this invention is to avoid the hand drainage from the air conditioners, to avoid the drainage of the condensate as such through a tube in the open air or in a sewer system as well as to avoid the accumulation in the condenser of the condensate which is not evaporated by the condenser by providing a condensate drainage system which does not need the use of drainage tubes in the sewer system or in the open air.
  • Another object of the present invention is to provide a fully evaporation of the atomized condensate flowing from the atomizing nozzle before falling on the ground.
  • the air conditioner either of the monobloc type intended to be applied in an opening of a wall or window of the room to be conditioned or of the split type having a unit placed in the inside of the room to be conditioned and unit placed in the outside, comprises a condensate drainage system having a condensate collecting vessel, an atomizing nozzle arranged on the outside for atomizing the condensate in the open air, a condensate conduit connecting the condensate collecting vessel to the atomizing nozzle, a pump for pumping the condensate from the collecting vessel to the atomizing nozzle and is characterized in that said atomizing nozzle is arranged in the warm air stream flowing from the condenser and generated by the ventilator provided in the air conditioner for cooling the condenser, said warm air stream causing the full evaporation of the atomized condensate before falling on the ground.
  • the atomizing nozzle is directed in the direction of the warm air stream flowing from said condenser.
  • the condensate drainage system according to the invention can be applied both to air conditioners of the monobloc type, which are designed to be placed in openings provided in a wall or a window of the room to be conditioned so that the condenser of the air conditioner is in communication with the outside for cooling it, and to portable air conditioners of "split" type comprising a unit placed on the inside of the room to be conditioned and a unit placed on the outside of the room to be conditioned.
  • Fig. 1 there is shown the condensate drainage system as applied to a split type air conditioner having an inside unit comprising a compressor, a ventilator and an evaporator and an outside unit comprising a condenser provided with its own ventilator.
  • the condensate collecting tray of which (not shown) is connected to a collecting vessel 1 through a condensate pipe 2.
  • a self-priming pump 5 is provided (which can best be seen in the right lower portion of Fig. 1 where the condensate collecting vessel 1 instead of having a parallelepipedal shape, has a shape with rounded side walls) the suction tube of which is immersed into vessel 1 and has at the lower end thereof a filter 11.
  • the delivery tube 4 of the pump 5 leads from the evaporator 9 to the condenser 10 which is placed on the outside, for example on a balcony, or suspended from the window sill, and is provided at the end thereof with an atomizing nozzle arranged at the center of the heat exchanger 7 of the condenser 10, on the outer wall thereof, so as to lie in the trajectory of the warm air flow generated by the ventilator 6 provided for cooling the condenser 10.
  • the atomizing nozzle 8 is supported in such a position by a rod.
  • an electronic level control device 3 is provided, which is designed to signal the minimum level of condensate, the maximum level of condensate as well as a level of overflow of condensate, said overflow occuring in the case of malfunctioning of the system.
  • Fig. 2 there is shown an embodiment wherein the pump 5, instead of being placed directly on the condensate collecting vessel 1, is placed within the condenser.
  • the tube 4 is the suction tube of pump 5 connecting the condensate collecting vessel 1 to the condenser 10, whereas the delivery tube is formed by the tube exiting from the pump and leading to the atomizing nozzle 8.
  • the condensate which is formed in the condenser 9 is transported via the tube 2, to the condensate collecting vessel 1.
  • the condensate level is controlled by the electronic device 3 which energizes the pump 5 when the drainage level is attaint.
  • the pump 5 is a self-priming pump and therefore does not require the presence of liquid for its starting, it is suitable for restarting after long interruption periods (winter pause).
  • Fig. 1 With pump arranged inside the evaporator-compressor-ventilator unit, it is possible to have a difference in height between inside unit 9 and outside unit 10 of 3-4 m, but as a counter-item the small noise of the pump operating in the room to be conditioned is to be accepted. With the pump arranged in the outside unit (Fig. 2) the noise produced by the pump is eliminated from the room to be conditioned, but the difference in height which can be overcome is of 1,5 m only.
  • the electronic control device 3 in addition to control the start and the stop operations of the condensate pump in the case of malfunctioning of the condensate drainage system, prevents the overflow of the condensate from the collecting vessel 1 by stopping the conditioner operation.
  • a release push-button (not shown) provides for the manual start of the pump in order to reset the normal operating conditions.
  • the condensate drainage system solves in a simple and efficient manner the problem of the condensate disposal from the above mentioned air conditioners because there is no longer the need of having a tube for draining the condensate in the sewer system, the need of leaving to the user attention the drainage operation in the case of air conditioners provided with a condensate collecting tray only and the need of periodically controlling the condensate level in the tray.
  • the system according to the invention is fully automatic because no intervention of the user is required except in the case of a stop of the air conditioner due to a malfuctioning of the system.
  • the condensate flowing from the nozzle in a finely amotized condition is fully evaporated in the open air due to the contribution of warm air flowing from the heat exchanger of condenser and moved by the ventilator, said warm air stream flowing in the direction of the condensate jet exiting from the atomizing nozzle. Therefore, with the system according to the invention there is not formation of condensate droplets flowing along the building walls which leave unaesthetic tracks and of condensate droplets flowing on building portions belonging to rooms placed below the outside unit.
