Air conditioner

Abstract

An air conditioner includes a first metal pipe 26 a, 26 b , a second metal pipe 19 a with a higher electric potential than the first metal pipe, and a first component 12 made of stainless steel and including a first connecting part 12 a, 12 b and a second connecting part 12 c . The first metal pipe 26 a, 26 b is connected to the first connecting part 12 a, 12 b of the first component 12 and the second metal pipe 19 a is connected to the second connecting part 12 c of the first component 12 , so that a refrigerant passage is formed from the first metal pipe 26 a, 26 b to the second metal pipe 19 a through the first component 12 . The first component 12 is one of a filter a muffler, a decompression device, a refrigerant storage, and a diverter. With this arrangement, the number of components of the air conditioner is reduced.

1 . An air conditioner comprising:
 a first metal pipe;   a second metal pipe with a higher electric potential than the first metal pipe; and   a first component made of stainless steel and including a first connecting part and a second connecting part,   the first metal pipe being connected to the first connecting part of the first component and the second metal pipe being connected to the second connecting part of the first component, so that a refrigerant passage is formed from the first metal pipe to the second metal pipe through the first component, and   the first component being one of a filter, a muffler, a decompression device, a refrigerant storage, and a diverter.   
     
     
         2 . The air conditioner according to  claim 1 , wherein, the first connecting part is located above the second connecting part. 
     
     
         3 . The air conditioner according to  claim 1 , wherein an end portion of the first connecting part is inserted into the first metal pipe. 
     
     
         4 . The air conditioner according to  claim 1 , further comprising: a second component connected to the opposite side of the first component of the first metal pipe; and a third component connected to the opposite side of the first component of the second metal pipe,
 each of the second component and the third component being one of a heat exchanger, a filter, a muffler, a decompression device, a refrigerant storage, a stop valve, and a diverter,   the first metal pipe being a refrigerant pipe made of aluminum and the second metal pipe being a refrigerant pipe made of copper, and   between the second component and the third component, the number of bended parts of the first metal pipe being smaller than the number of bended parts of the second metal pipe.   
     
     
         5 . The air conditioner according to  claim 1 , wherein,
 the first component is a filter,   the first metal pipe is a refrigerant pipe connected to a connection part of the filter on the heat exchanger side, and   the first metal pipe includes: a first section (PA) connected to the first connecting part of the filter and extending upward from the first connecting part; a second section (PB) connected to an upper end portion of the first section, extending upward from the upper end portion, being bended, and extending downward; and a third section (PC) connected to a lower end portion of the second section and extending downward.   
     
     
         6 . The air conditioner according to  claim 1 , wherein, the first component is a decompression device, the first metal pipe is made of aluminum, and the second metal pipe is made of copper. 
     
     
         7 . The air conditioner according to  claim 1 , wherein,
 the first component is a diverter, the first metal pipe is a refrigerant pipe connected to an outdoor heat exchanger and made of aluminum, and a decompression device and a stop valve are provided on the opposite side of the outdoor heat exchanger over the diverter, and   a pipe between the diverter and the decompression device and a pipe between the decompression device and the stop valve are made of copper.
