Outdoor unit of refrigeration cycle apparatus

Abstract

An outdoor unit of a refrigeration cycle apparatus to be installed in an external-wall internal space of a structure includes a casing, a heat exchanger accommodated in the casing, a first air-sending device configured to cause air to pass through the heat exchanger and discharge the air to the external-wall internal space, a second air-sending device configured to suck the air discharged to the external-wall internal space by the first air-sending device and discharge the air to an outside of the structure, and a divider that divides an inside of the casing into a first air passage and a second air passage. The heat exchanger and the first air-sending device are disposed in the first air passage. The second air-sending device is disposed in the second air passage.

1 . An outdoor unit of a refrigeration cycle apparatus, the outdoor unit being to be installed in an external-wall internal space of a structure, the outdoor unit comprising:
 a casing;   a heat exchanger accommodated in the casing;   a first air-sending device configured to cause air to pass through the heat exchanger and discharge the air to the external-wall internal space;   a second air-sending device configured to suck the air discharged to the external-wall internal space by the first air-sending device and discharge the air to an outside of the structure; and   a divider that divides an inside of the casing into a first air passage and a second air passage,   the heat exchanger and the first air-sending device being disposed in the first air passage,   the second air-sending device being disposed in the second air passage.   
     
     
         2 . The outdoor unit of a refrigeration cycle apparatus of  claim 1 , wherein the second air passage is located above the first air passage. 
     
     
         3 . The outdoor unit of a refrigeration cycle apparatus of  claim 2 ,
 wherein the casing includes a machine chamber that serves as a space accommodating a compressor, and   wherein the second air passage is located above the machine chamber.   
     
     
         4 . The outdoor unit of a refrigeration cycle apparatus of  claim 1 , wherein the casing includes a service panel disposed on a side of an indoor space of the structure.
