Air-conditioning system for rooms

Abstract

An air-conditioning system for rooms includes a cooling module associated to a heating system, a plurality of fan-convectors acting both as heating and cooling terminals, a single hydraulic circuit leading a fluid to said fan-convectors, said cooling module having a first inlet tube and a first outlet tube, said heating system having a second inlet tube and a second outlet tube, said single hydraulic circuit comprising an intake tube and a return tube. The cooling module comprises a three-way switching valve whose central outlet is connected to said intake tube, an inlet is connected to said second outlet tube, and an inlet is connected to said first outlet tube, with said return tube being connected to said second inlet tube and to said first inlet tube, so that said three-way switching valve connects said plurality of fan-convectors both during cooling and heating operating mode.

What is claimed is:  
     
         1 . Air-conditioning system for rooms comprising a cooling module ( 2 ) associated to a heating system ( 8 ), a plurality of fan-convectors (F 1 , . . . , Fn) acting as both heating and cooling terminals, a single hydraulic circuit ( 5 ,  7 ) leading a fluid to said plurality of fan-convectors (F 1 , . . . , Fn), said cooling module ( 2 ) being equipped with a first inlet tube (B) and a first outlet tube (A), said heating system ( 8 ) being equipped with a second inlet tube (D) and a second outlet tube (F), said single hydraulic circuit ( 5 ,  7 ) comprising an intake tube ( 5 ) and a return tube ( 7 ), said air-conditioning system further comprising a storage reservoir ( 4 ) and a circulation pump (P 1 ), said storage reservoir ( 4 ) being connected on one hand to said return tube ( 7 ) of said single hydraulic circuit ( 5 ,  7 ) and on the other to said circulation pump (P 1 ), said circulation pump (P 1 ) being connected to said first inlet pipe (B), wherein said cooling module ( 2 ) comprises a three-way switching valve (V 1 ) whose central outlet is connected to said intake tube ( 5 ) of said single hydraulic circuit ( 5 ,  7 ), an inlet is connected to said second outlet tube (F) of said heating system ( 8 ), and an inlet is connected to said first outlet tube (A) of said cooling module ( 2 ), said return tube ( 7 ) of said hydraulic circuit ( 5 ,  7 ) being connected to said second inlet tube (D) and to said first inlet tube (B), so that said three-way switching valve (V 1 ) connects said plurality of fan-convectors (F 1 , . . . , Fn) both during cooling and during heating operating mode.  
     
     
         2 . Air-conditioning system for rooms according to  claim 1 , wherein it further comprises a control unit ( 3 ) controlling said three-way switching valve (V 1 ), said cooling module ( 2 ) and said fan-convectors (F 1 , . . . , Fn).  
     
     
         3 . Air-conditioning system for rooms according to  claim 1 , wherein said cooling module ( 2 ) comprises a compressor ( 10 ), a capacitor ( 11 ), a lamination element ( 12 ) and an evaporator ( 13 ), each of said components being connected to the other by means of connection tubes (E).  
     
     
         4 . Air-conditioning system for rooms according to  claim 3 , wherein said control unit ( 3 ) controls the working of said compressor ( 10 ), of said plurality of fan-convectors (F 1 , . . . , Fn), of said three-way switching valve (V 1 ), of said circulation pump (P 1 ) and of said heating system ( 8 ).  
     
     
         5 . Air-conditioning system for rooms according to  claim 1 , wherein said heating system ( 8 ) is an independent boiler or a centralized installation or a district heating system.
