Description

This invention relates to an outdoor unit for an air conditioning system. As an outdoor unit for an air conditioning system, it is known to have a housing that is partitioned by a divider between a heat exchange chamber containing a heat exchanger and a machine room containing components and piping that make up the refrigerant circuit through which the refrigerant circulates. An electrical component support section for supporting electrical components such as control boards is provided within the machine room. In this type of outdoor unit, a first electrical component support section is provided adjacent to the front of the housing, and a second electrical component support section is provided adjacent to the side of the housing. On the rear side of the housing, piping and a compressor are arranged in an internal space enclosed by the first and second electrical component support sections (Patent Document 1). In this outdoor unit, by removing only the side panel on the side of the housing and detaching and moving the second electrical component support section, it becomes possible to easily attach and detach parts inside the machine room from the side of the housing, thereby improving the efficiency of maintenance and other operations.
