Indoor unit for air conditioning devices

Abstract

A gas-side pipe ( 70 ) is provided with a header body ( 71 a ) extending vertically along a side end portion ( 32 a ) of an indoor heat exchanger ( 32 ), a vertical tube portion ( 74 ) facing the header body ( 71 a), and a bent tube portion ( 73 ) connecting a lower end portion of the header body ( 71 a) and a lower end portion of the vertical tube portion ( 74 ) together. Part of a liquid-side pipe ( 80 ) is provided in a space (S 1 ) between the header body ( 71 a ), the vertical tube portion ( 74 ), and the bent tube portion ( 73 ).

1 . An indoor unit for an air conditioning device, the indoor unit comprising:
 an indoor fan ( 27 ); an indoor heat exchanger ( 32 ) arranged to surround the indoor fan ( 27 ); a gas-side pipe ( 70 ) coupling the indoor heat exchanger ( 32 ) and a gas communication pipe ( 3 ) together; and a liquid-side pipe ( 80 ) coupling the indoor heat exchanger ( 32 ) and a liquid communication pipe ( 2 ) together, the indoor unit being provided on a ceiling, wherein   the gas-side pipe ( 70 ) includes
 a header body ( 71   a ) extending vertically along a side end portion ( 32   a ) of the indoor heat exchanger ( 32 ), 
 a vertical tube portion ( 74 ) facing the header body ( 71   a ), and 
 a bent tube portion ( 73 ) connecting a lower end portion of the header body ( 71   a ) and a lower end portion of the vertical tube portion ( 74 ) together, and 
 part of the liquid-side pipe ( 80 ) is provided in a space (S 1 ) between the header body ( 71   a ), the vertical tube portion ( 74 ), and the bent tube portion ( 73 ). 
   
     
     
         2 . The indoor unit for an air conditioning device of  claim 1 , wherein
 the liquid-side pipe ( 80 ) is connected with an expansion valve ( 39 ) disposed inside the indoor heat exchanger ( 32 ).   
     
     
         3 . The indoor unit for an air conditioning device of  claim 2 , wherein
 the liquid-side pipe ( 80 ) is connected with
 a flow divider body ( 81   a ) disposed outside the indoor heat exchanger ( 32 ) and 
 a liquid relay pipe ( 82 ) coupling the flow divider body ( 81   a ) to the expansion valve ( 39 ), and 
   the liquid relay pipe ( 82 ) is disposed above the bent tube portion ( 73 ) so as to intersect with the bent tube portion ( 73 ) of the gas-side pipe ( 70 ).
