The purpose of the present invention is to provide an air guide-integrated evaporation cooler which allows a plurality of barrier plates, heat exchangers, and air guides for forming a dry channel and a wet channel to be integrally manufactured by a simple process, and a method of manufacturing the same. The air guide-integrated evaporation cooler for implementing the purpose includes a plurality of barrier plates; and gap units including a plurality of bars positioned between the plurality of barrier plates, disposed to be spaced apart from each other at a center portion thereof, and configured to form heat exchangers, and guides disposed at edges of the plurality of barrier plates and configured to determine a direction of a fluid flow.

An apparatus for conditioning a space includes a frame; an internal space within the frame, into which internal space a supply air flow is conducted; a cover panel into which a perforated area is arranged, the perforated area including perforations, each perforation having a diameter; and a heat exchanger arranged within the frame and including at least one heat exchanger coil, lamellas, and openings arranged between each adjacent lamella, each opening having a length.

An air flow controller for an air cleaner and an air cleaner are provided. The air flow controller may include a fan, and a housing, the fan being provided in the housing and the housing being movable from an initial horizontal position in which the air flow controller directs air flow in a vertical direction to an inclined position in which the air flow controller directs air flow in a diagonal direction.

An air cleaner is provided that includes a first air cleaning module including a first fan that generates an air flow toward a first discharge outlet from a first suction inlet; a second air cleaning module including a second fan that generates an air flow toward a second discharge outlet from a second suction inlet; a divider provided between the first air cleaning module and the second air cleaning module, the divider including a dividing plate space; and a printed circuit board (PCB) device provided in the dividing plate space.

An air cleaner is provided. The air cleaner may include a first air cleaning module including a first fan, a first filter, and a first inlet through which air is suctioned in a radial into the first filter; a second air cleaning module provided over the first air cleaner including a second fan, a second filter, and a second inlet through which air is suctioned in the radial direction to the second filter; and an air flow controller coupled with the second air cleaning module and including a third fan to control a flow of the air discharged from the second air cleaning module.

An air cleaner is provided that may include a first air cleaning module having a first fan that generates air flow from a first suction inlet toward a first discharge outlet; a second air cleaning module having a second fan that generates air flow from a second suction inlet toward a second discharge outlet; a dividing plate provided between the first air cleaning module and the second air cleaning module; and a display provided at inside of the dividing plate and in which a light source is provided.

An air cleaner and a method for controlling an air cleaner are provided. The air cleaner may include a first air cleaning module having a first fan and a first filter; a second air cleaning module having a second fan and a second filter, the second air cleaning module provided vertically over the first air cleaning module; an air flow controller provided at an upper side of the second air cleaning module and including a circulation fan; a sensor configured to sense a pollution level in a room space; an input configured to receive input of a command for an operation mode of a plurality of operation modes to operate the first and second air cleaning modules and the air flow controller; and a controller configured to drive at least one of the first fan, the second fan, or the circulation fan selectively and determine an amount of discharge air flow. Based on at least one of an operation mode input or the pollution level, the controller may operate one of (1) the first fan, (2) the first and second fans, (3) the first and second fans and the circulation fan, or (4) the second fan and the circulation fan.

An air cleaner is provided. The air cleaner may include at least one air cleaning module including a fan, a filter and an inlet through which air is suctioned into the filter; an air flow controller configured to be movably disposed on the at least one air cleaning module and including an air flow control fan to control a flow of the air discharged from the at least one air cleaning module. The air flow controller may be movable from a first position at which the air is discharged in an upward direction to a second position at which the air is discharged in a diagonally upward direction.

A method for air purification is disclosed, comprising directing air through a particle removal filter that acts to filter the air for particle phase pollutants to thereby produce particulate filtered air; and directing an amount of the particulate filtered air through a gas removal filter that acts to filter the particulate filtered air for gas phase pollutants to thereby produce gas filtered air; the particle removal filter with the first blower and the gas removal filter with the second blower are housed in different enclosures and they are allowed to operate in a way that; the two different units are selectable to operate separately without connection in a first mode, and to operate together connectively in a second mode; when the two different units are selected to operate together connectively in the second mode, the amount of particulate filtered air directed through the gas removal filter is based on a concentration of particle phase pollutants in the air.

A centrifugal ceiling fan adapted to evenly ventilate and heat its surrounding area. The fan comprises a casing defining a top, a side, and a bottom. The air inlet is provided in the top and the air outlet comprises a first passage provided in the side and a second passage provided in the bottom, and a central dome for regulating the flow of air between the first passage and the second passage to a desired proportion. The fan comprises a centrifugal propeller having blades which are curved and have a variable width such that rotation of the centrifugal propeller causes air to be received from said air inlet and to be pushed from said air outlet in substantially all directions between the first direction and the second direction. The dome comprises a heat source for heating air pushed downward from the bottom. Whereby, unheated air is pushed sideways and heated air is pushed downward and for evenly ventilating and heating a room in which the centrifugal ceiling fan is installed.
