Evaporative condenser and refrigeration system equipped with said evaporative condenser

Abstract

An evaporative condenser for use in a refrigeration system includes an inclined plate-like refrigerant cooling portion for cooling and condensing refrigerant, an inclined plate-like water spraying portion for spraying the cooling portion with cooling water to cool the refrigerant cooling portion, a casing having an air inlet for taking in air, an air outlet for discharging air, and a draft fan for generating airflow from the air inlet to the air outlet inside the casing. The refrigerant cooling portion has multiple condenser coils arranged in an inclined manner with respect to the horizontal direction to cool the refrigerant while causing the refrigerant to flow downward therethrough. The water spraying portion has multiple water spraying nozzles arranged in an inclined manner along the condenser coils to spray the condenser coils with cooling water. The evaporative condenser efficiently condenses and devolatilizes gaseous refrigerant delivered sequentially after circulating in a condensing cooling cycle.

1 . An evaporative condenser comprising:
 an inclined plate-like refrigerant cooling portion for cooling and condensing refrigerant delivered sequentially after circulating in a condensing cooling cycle;   an inclined plate-like water spraying portion for spraying the refrigerant cooling portion with cooling water to cool the refrigerant cooling portion;   a casing having an air inlet for taking in air and an air outlet for discharging air used for evaporating cooling water sprayed from the water spraying portion and   a draft fan for generating an airflow from the air inlet to the air outlet inside the casing;   
       wherein:
 the refrigerant cooling portion has a plurality of condenser coils arranged in a downward-inclined manner with respect to the horizontal direction to cool the refrigerant while causing the refrigerant to flow therethrough downward; and 
 the water spraying portion has a plurality of water spraying nozzles arranged in an inclined manner along the condenser coils to spray the condenser coils with the cooling water. 
 
     
     
         2 - 6 . (canceled) 
     
     
         7 . The evaporative condenser according to  claim 1 , wherein the water spraying portion is arranged in an inclined manner on the windward side of the refrigerant cooling portion. 
     
     
         8 . The evaporative condenser according to  claim 1 , including an eliminator provided between the refrigerant cooling portion and the draft fan and also between the water spraying portion and the draft fan, said eliminator being arranged in an inclined manner along the refrigerant cooling portion and the water spraying portion. 
     
     
         9 . The evaporative condenser according to  claim 1 , wherein:
 the air inlet is provided in one of a set of opposed side wall surfaces of the casing;   the air outlet is provided in a top surface of the casing;   the casing has a bottom wall surface opposed to said air outlet; and   the condenser coils are inclined downward from a location adjacent an upper part of one of the side wall surfaces of the casing toward said casing bottom wall surface.   
     
     
         10 . The evaporative condenser according to  claim 1 , including a cooling water clarifying portion, and wherein the water spraying portion is connected to said cooling water clarifying portion for clarifying the cooling water. 
     
     
         11 . A refrigeration system configured with a condensing cooling cycle having an evaporative condenser according to  claim 1 .
