Embodiment Construction

[0028] A fan assembly incorporating nozzles will now be described which is capable of generating an air flow that replicates the flow characteristics of natural wind and can therefore be considered to provide greater thermal comfort to the user. The term "fan assembly" refers herein to a fan assembly configured to generate and deliver air flow for thermal comfort and / or environmental or climate control purposes. Such a fan assembly may be capable of generating one or more of a flow of dehumidified air, a flow of humidified air, a flow of purified air, a flow of filtered air, a flow of cooling air, and a flow of heated air.

[0029] The fan assembly includes a base arranged to support the fan assembly on a surface, an airflow generator arranged to generate an airflow, and an air outlet arranged to emit the airflow from the fan assembly At least a portion of wherein the air outlet is arranged to swing relative to the base. The fan assembly also includes a controller arranged to...

Abstract

A fan assembly is provided, which includes a base, an air flow generator and an air outlet, The base is arranged to support the fan assembly on a surface, The air flow generator is arranged to generate air flow, The air outlet is arranged to emit at least a part of the air flow from the fan assembly, The air outlet is arranged to swing relative to the base. The fan assembly also includes a controller, The controller is arranged to control the swing of the air outlet relative to the base, The controller is arranged to change the swing speed of the air outlet for each swing.

Description

technical field [0001] The invention relates to a fan assembly. Background technique [0002] Traditional household fans used for thermal comfort and / or environmental or climate control typically produce a relatively constant air flow. However, thermal comfort studies have shown that natural or light breezes can produce a greater cooling sensation than these steady streams of artificial air. In particular, both field studies and controlled experiments have shown that natural breezes can generate a stronger thermal response or sensation in the human body than a constant air flow. [0003] Accordingly, it would be desirable to provide a fan assembly that can generate an air flow that replicates the flow characteristics of natural wind and thus can be considered to provide a more comfortable cooling sensation than a steady artificial air flow. However, simulating natural outdoor airflow in indoor environments is a difficult task given the apparently chaotic or unstable nature...
