Evaporative condenser with micro water drolets forming ultra thin film

Abstract

Water evaporation with accompanying large amount of heat absorption is used in an apparatus and methods in cooling hot refrigerant in a condenser as result of work by an air conditioning compressor. A centrifugal water droplet generator and projector are designed with air flow modification of droplet travel paths for maximum even coating of condenser surfaces with thin water film for maximum evaporation efficiency. Vacuum is also used in the system for lowering of water evaporation temperature and carrying away moisture saturated air to further increase efficiency of condenser cooling.

1 . An apparatus for cooling a refrigerant in a condenser for an air conditioner or refrigeration device comprising:
 Means for generating controlled uniform-sized water droplets with a rotating centrifugal droplet generator and projecting droplets to cover all surface areas of condenser(s) located on 4 sides of a sealed chamber surrounding the droplet generator, and means to alter traveling paths of droplets with air to deposit a thin water film on condenser surfaces, plus means to provide a vacuum to lower air pressure surrounding condenser to lower water evaporation temperature to increase water evaporation rate and absorption of heat from condenser surfaces while removing moisture in chamber during process of water evaporation;
 A large suction fan means to hasten water evaporation by air blowing on the water film On the condenser surface. 
 a motorized rotating centrifugal droplet generator with open slots covered with a chemically inert screen means to generate small uniform-sized droplets and permit air flow to exit droplet generator altering travel directions of sprayed droplets covering virtually all surface areas of condenser, 
 a perforated tube means to deliver water to inner surface of rotating droplet generator for atomization anchored to bottom of air tight chamber, 
 a plastic air router means for delivery of air flow with multi-channels branching from a central tube and anchored to the chamber bottom, 
 a vacuum inlet tube means for delivering of vacuum and removal of moist air. 
   
     
     
         2 . The apparatus as in  claim 1 , wherein said water droplet generator, sprayer, and air flow pattern modifier produce a uniform thin water film covering surfaces of condenser. 
     
     
         3 . The apparatus as in  claim 2  wherein said thin water film provides a short path for heat from condenser to travel to the thin water film surface to be evaporated aiding efficiency of evaporation. 
     
     
         4 . The apparatus as in  claims 1 ,  2 , and  3  wherein said vacuum is provided for lowering of water evaporation temperature to increase rate of water evaporation leading to shortened time required for compressor operation than traditional air cooled method with hot outdoor air.
