1. An air conditioner comprising:
a casing including:
a partition plate that:
separates a heat-source-side space of the casing through which outdoor air passes and a utilization-side space of the casing through which indoor air passes,
blocks airflow between the heat-source-side space and the utilization-side space; and
a bottom plate that:
includes a first opening for supply air and a second opening for return air, and
closes a bottom surface of the utilization-side space;
a heat-source-side heat exchanger in the heat-source-side space that causes heat exchange between a refrigerant and the outdoor air;
a utilization-side heat exchanger in the utilization-side space that causes heat exchange between the indoor air and the heat-exchanged refrigerant;
a first duct that extends from the first opening to a first indoor air conditioning target space;
a second duct that extends from the second opening to a second indoor air conditioning target space; and
a standing part surrounding a periphery of at least one of the first opening or the second opening.
