Abstract: A double-layer blade ceiling fan capable of adjusting the arrangement of blades includes a motor and at least two blades. The motor has a stationary part and two rotating parts. The rotating parts are spaced apart from the stationary part. The rotating parts each have a plurality of mounting portions that are arranged around a central axis of the motor. The stationary part has an upper connecting portion and a lower connecting portion. The mounting portion is configured for connection of one of the blades. At least one of the blades is fixed to each of the rotating parts. The blades mounted to the rotating parts are selectively arranged in a same or different pattern for regulating air flow. When the blades and the rotating parts are rotated, the upper connecting portion and the lower connecting portion are not affected.

Abstract: A multi-stage compressor assembly is disclosed. Each of the stages of the compressor assembly has rows of blades arranged to rotate in counter-opposite directions, and this is effective to produce relatively high specific work, and high flow-capacity in a compact footprint at moderate blade tip speeds. In one non-limiting application, the compressor assembly can be utilized to compress a gas having a low-molecular weight and density, such as hydrogen.

Abstract: A method for controlling an air-cooled device (1) for compressing a gas, which device includes at least one element (2) for compressing the gas, at least one air-cooled cooler (9, 12) for cooling a fluid in the device (1) and two or more fans (10, 13), at least one of the fans (10, 13) being an adjustable-speed fan (13) for generating a flow of cooling air for cooling the air-cooled cooler (9, 12). When the air-cooled cooler (9, 12) does not need to cool, the method includes controlling the speed of the adjustable-speed fan (13) to a minimum required speed in order to avoid at least a backflow of cooling air traveling in a direction opposite to the flow.
