Device for enhancing efficiency of air-conditioner

Abstract

Device for enhancing efficiency of air-conditioner, including a water reservoir, a water level sensor, a controller and a water-injecting section. The water reservoir receives the condensed water produced from the water exhaust of the vaporizer of the air-conditioner. The water level sensor is disposed in the reservoir for real-time sending water level signal to the controller for judging whether water should get into the water reservoir or discharge therefrom. The controller is able to detect the operation state of the compressor of the air-conditioner to activate the water-injecting section to inject water onto the heat-radiator at proper time so as to continuously decrease temperature of the heat-radiator and the air therearound and enhance efficiency of the air-conditioner and avoid load loss due to high temperature of the components of the air-conditioner after long period of operation.

What is claimed is:  
     
         1 . Device for enhancing efficiency of air-conditioner, comprising: 
 a water reservoir mounted on inner or outer side of the air-conditioner at a certain position in accordance with the requirement of the air-conditioner, the water reservoir being provided with water-refilling port and draining port for reserving or draining condensed water discharged by the air-conditioner;    a water level sensor disposed in the reservoir for real-time sending water level signal to a controller;    a controller composed of a processing unit, a load sensing unit and a relay unit, the load sensing unit being connected with the compressor of the air-conditioner for always sensing the operation state of the compressor, the relay unit being electrically connected with a driving motor of a water-injecting section, by means of the control of the processing unit, the water-injecting section being activated to inject water or stop injecting water; and    a water-injecting section composed of a driving motor, a water outlet tube and an injector, the driving motor being disposed in the reservoir and powered on/off via the relay unit, one end of the outlet tube being disposed at an outlet end of the driving motor, while the other end of the outlet tube extending to a corresponding portion of the heat-radiator of the air-conditioner, the injector being disposed on a section of the outlet tube corresponding to the heat-radiator for injecting water onto the heat-radiator, whereby the processing unit receives signals of operation state of the compressor from the load sensing unit and according to preset value automatically activate or shut off the relay unit for controlling water injection operation of the water-injecting section.    
     
     
         2 . Device for enhancing efficiency of air-conditioner as claimed in  claim 1 , wherein the water-refilling port of the water reservoir through a pipeline is able to receive the condensed water produced from the water exhaust of the vaporizer of the air-conditioner.  
     
     
         3 . Device for enhancing efficiency of air-conditioner as claimed in  claim 1 , wherein the inlet end of the driving motor is provided with a filter mesh.  
     
     
         4 . Device for enhancing efficiency of air-conditioner as claimed in  claim 1 , wherein the injector of the water-injecting section is a port and the water is injected in linear state.  
     
     
         5 . Device for enhancing efficiency of air-conditioner as claimed in  claim 1 , wherein the injector of the water-injecting section is a nozzle and the water is injected and quickly atomized in a bevel state to quickly combine with the surface of the heat-radiator or hot air.  
     
     
         6 . Device for enhancing efficiency of air-conditioner as claimed in  claim 1 , wherein an outdoor temperature sensor is disposed on outer side of the air-conditioner.  
     
     
         7 . Device for enhancing efficiency of air-conditioner as claimed in  claim 1 , wherein a water conducting section is disposed at a certain portion of the reservoir, the water conducting section being connected to the pipeline of tap water, the water-conducting section via an electromagnetic valve controlling water flow, the electromagnetic valve receiving the signal coming from the controller to close or open the pipeline, permitting the tap water to get into the reservoir.
