Abstract

An outdoor unit includes a housing, a heat exchanger provided inside the housing to exchange heat between refrigerant and a heat medium, and a valve provided inside the housing and connected to the heat exchanger by a pipe, in which a lower end of the heat exchanger is positioned above a connection unit configured to connect the valve and the pipe.

1 . An outdoor unit comprising:
 a housing;   a heat exchanger provided inside the housing to exchange heat between refrigerant and a heat medium;   a valve provided inside the housing and connected to the heat exchanger by a pipe; and   a compressor placed on a bottom surface inside the housing and configured to compress refrigerant,   a lower end of the heat exchanger being positioned above a connection unit configured to connect the valve and the pipe and being positioned above an upper end of the compressor when the compressor is inclined at 45 degrees.   
     
     
         2 . (canceled) 
     
     
         3 . The outdoor unit of  claim 1 , wherein
 the compressor includes   a suction pipe configured to suck refrigerant, and   a discharge pipe configured to discharge refrigerant,   wherein the suction pipe or the discharge pipe is a flexible pipe.   
     
     
         4 . The outdoor unit of  claim 1 , wherein the valve and the pipe are connected by brazing. 
     
     
         5 . The outdoor unit of  claim 1 , further comprising a fan provided to an upper portion of the housing and configured to send a heat medium to the heat exchanger. 
     
     
         6 . The outdoor unit of  claim 1 , wherein
 the housing has a rectangular tubular shape, and   the heat exchanger is provided to four side surfaces of the housing.   
     
     
         7 . The outdoor unit of  claim 1 , wherein the heat exchanger is composed of a first plate having an L shape and a second plate having an L shape in a top view. 
     
     
         8 . The outdoor unit of  claim 1 , wherein the heat exchanger is composed of a first plate having a U shape and a second plate having a linear shape in a top view. 
     
     
         9 . The outdoor unit of  claim 7 , wherein
 the heat exchanger is a fin-and-tube heat exchanger, and   a tube of one of the first plate and the second plate is composed of a circular tube and a tube of an other one of the first plate and the second plate is composed of a flat tube.   
     
     
         10 . The outdoor unit of  claim 8 , wherein a number of rows of the second plates is larger than a number of rows of the first plates.
