Abstract: An air conditioner may provide a a fan housing assembly that moves in the front-rear direction by the operation of an actuator, and the fan housing assembly moves so as to pass through a front outlet arranged on a door assembly to be in a projected state, and the front end of the fan housing assembly protrudes further to the front than the front surface of the door assembly; and through the projected state, may provide conditioned air by a direct air flow to a long-distance target region. The configuration may enable the minimization of interference between the discharged air and the door assembly, and the minimization of flow loss of the discharged air since, when the fan housing assembly is in the projected state, a steering grill is in a state of protruding to the outside of the door assembly by passing through the front outlet.

Abstract: A fan coil unit includes a cabinet, a heat exchanger located in the cabinet, an airflow inlet to admit an airflow into the cabinet, and an airflow outlet to allow the airflow to exit the cabinet. A fan is located in the cabinet to urge the airflow through the cabinet. The fan has an axis of rotation perpendicular to a general flow direction of the airflow. A method of operating a fan coil unit includes flowing an airflow into a cabinet via an airflow inlet and through a fan. The fan is oriented such that a fan axis of rotation is perpendicular to a general flow direction of the airflow from the airflow inlet to an airflow outlet. The airflow is urged across a heat exchanger located in the cabinet, the heat exchanger conditioning the airflow and is output from the cabinet through the airflow outlet.
