Abstract

A fan includes a motor, an impeller and a stator. The fan defines an air flow passage between an air inlet and an air outlet. The fan has a mode of operation and an arrangement such that, in use, the trajectory of the air flow through the air inlet is up to 360° in a direction which is generally perpendicular to the axis of rotation of the impeller. The trajectory of the air flow through the air outlet is up to 360° in a direction which is generally perpendicular to the axis of rotation of the impeller, and the air flow through the air flow passage turns generally 180°. The fan has a mode of constant operation, and, in this mode, the operating point of the fan falls with the stall region of the fan characteristic.

Abstract

An air conditioning unit (2) comprises a main body (3) including an air inlet (24) and an air outlet (22), the main body (3) defining an airflow passage between the air inlet (24) and the air outlet (22). A fan (28) is disposed within the airflow passage and a thermal element (26) is disposed within the airflow passage upstream of the fan (28). The main body (3) has a front face exposed to a temperature controlled space (8), on which the air outlet is disposed, and the air inlet and thermal element are disposed around the periphery of the front face.
