Kitchen Air-Conditioning System

Abstract

A kitchen air-conditioning system comprises an air-conditioning assembly (1) and a range hood assembly (2); the air-conditioning assembly (1) comprises a compressor (11), a first heat exchanger (12) and a second heat exchanger (13), the compressor (11) is connected with the first heat exchanger (12) and the second heat exchanger (13) through a plurality of refrigerating medium pipes (14); the range hood assembly (2) comprises a fan (21) with a fan outlet (211), the compressor (11) is attached to the range hood assembly (2), and the first heat exchanger (12) is disposed inside the air exhaust passage. So the entire structure of the system is more compact, and easier for installation without separate installation of an air-conditioner outdoor unit, and flue gas discharged into the air exhaust passage can take away the heat of the first heat exchanger or heat the first heat exchanger, thereby improving the energy efficiency of the air-conditioner.

1 . A kitchen air-conditioning system, comprising:
 an air-conditioning assembly ( 1 ) and a range hood assembly ( 2 );   wherein,   the air-conditioning assembly ( 1 ) further comprises a compressor ( 11 ), a first heat exchanger ( 12 ) and a second heat exchanger ( 13 ), the compressor ( 11 ) is connected with the first heat exchanger ( 12 ) and the second heat exchanger ( 13 ) through a plurality of refrigerating medium pipes ( 14 ), and the first heat exchanger ( 12 ) is connected with the second heat exchanger ( 13 ) through a refrigerating medium pipe ( 14 );   the range hood assembly ( 2 ) comprising a fan ( 21 ) with a fan outlet ( 211 ) and an air exhaust passage connected to the fan outlet ( 211 );   wherein, the compressor ( 11 ) is attached to the range hood assembly ( 2 ), and the first heat exchanger ( 12 ) is disposed inside the air exhaust passage.   
     
     
         2 . The system of  claim 1 , wherein the air exhaust passage is divided into a first air exhaust passage ( 22 ) and a second air exhaust passage ( 23 ) by a turnout ( 31 ), and a switching valve ( 3 ) is disposed at the turnout ( 31 );
 the switching valve ( 3 ) connects the fan outlet to the first air exhaust passage ( 22 ) or to the second air exhaust passage ( 23 ); and   the first heat exchanger ( 12 ) is disposed inside the first air exhaust passage ( 22 ).   
     
     
         3 . The system of  claim 2 , wherein a fume purification device ( 4 ) is disposed inside the first air exhaust passage ( 22 ) and in front of the first heat exchanger ( 12 ). 
     
     
         4 . The system of  claim 1 , wherein the air-conditioning assembly ( 1 ) comprises a fresh air inlet ( 15 ) and a fresh air outlet ( 16 );
 the fresh air inlet ( 15 ) is in communication with external environment, and the fresh air outlet ( 16 ) locates in front of the second heat exchanger ( 13 ) and communicates with interior space of the kitchen.   
     
     
         5 . The system of  claim 4 , wherein a plurality of fresh air purification devices ( 17 ) is disposed in air ducts of the fresh air inlet ( 15 ) and in the fresh air outlet ( 16 ). 
     
     
         6 . The system of  claim 1 , wherein a throttle valve ( 18 ) is disposed in one of the refrigerating medium pipers ( 14 ) between the first heat exchanger ( 12 ) and the second heat exchanger ( 13 ). 
     
     
         7 . The system of  claim 1 , wherein a four-way valve is disposed on one of the refrigerating medium pipes ( 14 ). 
     
     
         8 . The system of  claim 1 , wherein the air-conditioning assembly ( 1 ) further comprises a motor ( 193 ), a first fan ( 191 ) and a second fan ( 192 ), the first fan ( 191 ) and the second fan ( 192 ) are coaxially mounted to the motor ( 193 );
 the first fan ( 191 ) and the second fan ( 192 ) rotate together driven by the motor ( 193 ), and both are disposed at back of the second heat exchanger ( 13 ).
