An air purifier is disclosed having an electrostatic chamber and a germicidal chamber, wherein the two chambers are distinct and there is no air flow communication between the electrostatic and germicidal chambers.

An indoor unit of an air conditioner is provided. The indoor unit includes a main chassis, a front frame, a heat exchanger and a fan, a front panel, a filter, and a filter frame. The main chassis constitutes a rear appearance. The front frame is formed on the front of the main chassis to constitute a front appearance. The heat exchanger and the fan are disposed in the inside of the main chassis. The front panel shields the front side of the front frame. The filter is formed at the back of the fr...

An air purifier provides various air purification functions relating to various environmental conditions by increasing a purification function relative to specific contaminants through replacement of a filter based on the environment to be purified. The air purifier includes a main body of a structure allowing air to pass therethrough. A replaceable filter is received into the main body and is replaceable on a basis of the environmental properties of a space to be purified, removing contaminants...

An air damper includes a cylinder having a bottom, a piston received inside the cylinder to move freely back and forth coaxially, and an orifice provided in the piston. The piston is formed of a synthetic resin, and has a piston rod extending toward a side of the cylinder opposite to the bottom, and a recess portion provided on a portion facing the bottom in order to prevent sink or the like during molding of the piston. A protruding portion is provided on the bottom of the cylinder to protrude ...

An air-bag is formed using two substantially identical, but inverted, fabric elements. Each element defines a generally rectangular region having, at one narrow end thereof, a generally triangular extension, one side of which is co-extensive with one side of the rectangular region. The other side of the rectangular region has a triangular or thumb-like projection. The two elements are substantially superimposed with the rectangular regions thereof aligned. If the ends of the rectangular regions ...

An air conditioner is disclosed. The air conditioner includes a frame having air suction holes formed at upper and opposite lateral surfaces thereof and an air discharge hole formed at a front surface thereof, a heat exchanger having upper, left and right heat exchanger portions located along the air suction holes, and a fan disposed below the heat exchanger and adapted to suction air from radial and rearward directions thereof and to blow the air in a forward direction.

A mechanism configured to interact with air, which has been sucked through a device that imparts turbulence to the air, causes a redistribution of components (e.g., oxygen and nitrogen) in the air so that when the air arrives at a location where the oxygen is to be consumed there is an enriched supply of oxygen available. The effects of a first stage of turbulence of the induced air is reduced, resulting in a higher density supply to the atomization point and to the combustion chamber, in the ca...

An improved air diffuser is provided, including a housing having a bottom and an upwardly extending side wall with air slots to receive air. The housing supports a grille, and a flow regulator fits within the housing. The diffuser is configured to be secured to a floor by a mounting assembly, including a trim ring and a plurality of retaining mechanisms. The trim ring defines a flange and brackets for receiving the retaining mechanisms. Each retaining mechanism defines an L-shaped mount having h...

An air conditioner has a heat source refrigerant circuit, utilization refrigerant circuits, a pressurizing circuit, and a cooler. The heat source refrigerant circuit is configured by an interconnection of a compression mechanism, a heat source heat exchanger, and a heat source expansion valve that reduces a pressure of refrigerant condensed in the heat source heat exchanger. The pressurizing circuit is disposed in the heat source refrigerant circuit and causes high-pressure gas refrigerant compr...

An air belt device includes a first cover member and a second cover member connected to each other defining an interior surface having an interior cavity. An inflatable member is at least partially disposed within the interior cavity. The inflatable member is folded with sewn edge portions folded inward.
