An air circulation system includes at least one flow generator to generate an airflow, an air inlet, a first air outlet and a second air outlet each for exhausting airflow, an air conditioning device to air condition the exhausted airflow, and a controller. The controller is configured to position at least one of the first and second air outlets to be vertically separated from each other and to operate the flow generator to provide the exhaust airflow to the first and second air outlets. The exhaust airflow from the first and second air outlets are of different temperatures.

Air circulation apparatus and related methods

A drying apparatus includes a body, an airflow inlet, a bar supported by the body, the bar including an airflow outlet, and at least one flow generator to receive inlet air from the airflow inlet and to expel forced airflow through the airflow outlet. At least one motor is provided to rotate the bar about an axis oriented substantially parallel to a drying face of the body, the rotation of the bar reorientating the airflow outlet.

Drying apparatus and related methods

A forced airflow drying apparatus includes a body including an air inlet, a flow guide having a first end coupled to the air inlet and a second end opened to an upstream side of a filter unit, and an airflow generator to generate a forced airflow. The airflow generator has a first end and a second end, where the first end of the airflow generator is opened to a downstream side of the filter unit. An air outlet is in communication with the second end of the airflow generator to receive the forced airflow from the airflow generator and to expel the forced airflow out of the body.

A forced airflow drying apparatus includes a body including a pair of air inlets to receive inlet air which is channeled to an upstream side of a filter unit, a pair of body airflow generators to generate a first forced airflow, each body airflow generator having a first end and a second end, where the first end of each body airflow generator is opened to a downstream side of the filter unit, a pair of thermoelectric devices configured to control a temperature of the first forced airflow, and a first air outlet, in communication with the second end of each body airflow generator, to receive the forced airflow from the body airflow generators and to expel the forced airflow out of the body. The forced airflow drying apparatus further includes a bar and a drive apparatus configured to movably drive the bar relative to the body, the bar including a second pair of airflow generators to generate a second forced airflow, a pair of resistance heaters to control a temperature of the second forced airflow prior to being expelled from the second air outlet, and a second air outlet to expel the second forced airflow from the bar.

A drying apparatus includes a body and a rotatable foot pad located on the lower part of the body to dry a user's feet. An air inlet is provided, and a flow generator to receive inlet air from the air inlet and generate an airflow to the top surface of the foot pad.

A drying apparatus includes a body, a bar movable relative to the body; an air inlet, a flow generator to receive inlet air from the air inlet and generate an airflow, and a bar air outlet at the bar for exhausting the airflow from the flow generator. A bar orientation mechanism is operable to control an orientation of the bar.

A body dryer includes an airflow generator to generate a flow of air, an inlet to pass air from the surroundings to the airflow generator, an outlet to vent the air from the airflow generator, a body, and a movable bar, the bar supported by the body. A drive assembly is provided between the body and the bar, the bar movably driven relative to the body. A noise cancellation device is provided to cancel or reduce noise in at least one of the airflow generator and the drive assembly.

Drying apparatus and related noise suppression methods

A drying apparatus includes a body, a controller, a thermal sensor to sense an ambient temperature, a humidity sensor to sense an ambient humidity, an air outlet to vent an airflow, a flow generator to generate the airflow within the body, and a thermoelectric device including an inward surface and an outward surface, where the inward surface heats or cools the airflow generated by the flow generator. The controller is configured to control a temperature of the inward surface of the thermoelectric device based on the ambient temperature and the ambient humidity.

Provided is a method for producing a high-carbon number saturated hydrocarbon compound by subjecting a mixed biomass solution containing benzyl phenyl ether (CHCHOCH) to a two-step reaction process using a difunctional catalyst having an acid catalyst combined with a metal catalyst. The method allows development of a fuel substituting for and supplementing petroleum through decomposition and conversion of a biomass containing lignin or the like, thereby providing a non-petroleum based biofuel.
