1. An air conditioning apparatus that is connected via a duct to a plurality of blow-out ports formed in an air-conditioning target space and that sends air to the blow-out ports, comprising:
a casing that includes an inlet port that takes in air and an outlet port to which the duct is connected, the casing forming an airflow path extending from the inlet port to the outlet port;
a fan that is disposed in the casing and sends air from the inlet port to the outlet port in the airflow path;
a member that allows air to pass therethrough and that is disposed in the airflow path;
a differential pressure gauge that measures a differential pressure between an upstream side and a downstream side, in an air flow direction, of the member that allows air to pass therethrough, the differential pressure gauge having an upstream pressure take-out provided directly opposing an upstream surface of the member that allows air to pass therethrough, and a downstream pressure take-out provided directly opposing a downstream surface of the member that allows air to pass therethrough; and
a controller that adjusts a rotational speed of the fan based on a measured value of the differential pressure gauge.
