Air conditioning system

Abstract

A supplementary air conditioning system includes an indoor heat exchanger and an outdoor heat exchanger. The indoor heat exchanger is fanless and includes indoor tubes installed so as to be inclined to a ceiling of a room. The indoor tubes make diagonal contact with a high-temperature air zone in an upper part of the room and refrigerant inside the indoor tubes is heated by the air zone so as to boil and vaporize and air in the air zone flows down through the indoor heat exchanger. The external heat exchanger includes outdoor tubes installed outside at a higher position than the indoor tubes and are connected to the indoor tubes via connecting pipes with no compressor therebetween. The outdoor tubes condense and liquefy the refrigerant boiled and vaporized in the indoor tubes and return the refrigerant to the indoor tubes.

         11 . A system comprising:
 an indoor heat exchanger that is a fan-less heat exchanger and includes an indoor tube installed so as to be inclined to the horizontal, the indoor tube contacting a high-temperature air zone in an upper part of a room and refrigerant in the indoor tube being heated by the high-temperature air zone so as to boil and vaporize with air in the high-temperature air zone flowing down through the indoor heat exchanger:   an outdoor heat exchanger that includes an outdoor tube installed outside at a higher position than the indoor tube, the outdoor tube being connected to the indoor tube via connecting pipes without a compressor being interposed therebetween and the outdoor tube condensing and liquefying the refrigerant boiled and vaporized in the indoor tube and returning the refrigerant to the indoor tube: and   a floor-standing air conditioner installed on a floor of the room,   wherein the indoor heat exchanger is disposed so as to directly contact the high-temperature air and a down flow produced by the indoor heat exchanger is drawn into an air intake of the floor-standing air conditioner.   
     
     
         12 . The system according to the claim  1 ,
 wherein the indoor tube is installed so as to be inclined with respect to a ceiling of the room.   
     
     
         13 . The system according to the claim  1 , wherein the indoor heat exchanger is connected via a duct to the air intake of the floor-standing air conditioner.
