An air conditioner includes a main unit having an enclosure defining an air outlet. The enclosure contains a heat exchanger generating a cool air or a warm air forming airflow running out of the air outlet. A pair of fan units are disposed on the opposite sides of the air outlet. The fan units are configured to suck a room air and to blow the room air. The airflow of the room air can be utilized to control the direction and/or movement of the airflow of the cool air or the warm air. The cool air or the warm air can be conveyed to desired locations.

An indoor unit of an air conditioner has an improved discharge structure of air. The indoor unit of an air conditioner includes a panel which defines an external appearance thereof and has an opening, a mixed flow fan which is located within the panel, a heat exchanger unit which is located rearward of the mixed flow fan, an inlet port which is located rearward of the heat exchanger unit so that air is suctioned from rearward of the heat exchanger unit to be introduced into the mixed flow fan, an outlet port which is exposed forward of the panel through the opening so that the air passing though the mixed flow fan is discharged through a front portion of the panel, and a plurality of circular louvers to open and close the outlet port by moving outwards from a center of the outlet port.

A device for sanitizing a unit of an air conditioning system having a source of sanitizing fluid, means for the controlled delivery of a jet of sanitizing fluid, suctioning means to generate suction flow is provided. The device has suction opening shaped to direct the suction flow towards a determined direction with respect to the direction of the jet of sanitizing fluid. The suction opening is smaller than the unit of the air conditioning to be sanitized in order to be alternately moved from a first portion of the unit towards a second portion of the same unit.

An air conditioning system includes a climatic beam located in a room. The climatic beam includes a first portion and a second portion, and a divider located along a length of the climatic beam to separate the first portion from the second portion. The climatic beam further includes a coil supplied with a flow of fluid. A fresh air duct is connected to the first portion to provide a flow of fresh air into the first portion, and a fan is located at the second portion and is configured to draw a flow of primary air across the coil and into the second portion. A beam exit allows a flow of the fresh air and the primary air into the room.

A wooden-cabinet for air conditioning system including a cabinet for housing an air conditioning system wherein the cabinet is depicted in the form of a fireplace or a wood mantel, and the cabinet is preferably made of wood material. The cabinet preferably houses the indoor unit of the air condition system and includes heat pumps, split type heat pumps, split-HVAC, hydronic based heating systems and like. The cabinet comprise a substantially rectangular shaped enclosure having the air inlet, air outlet, components of air condition system, control unit etc. The faux fireplace cabinet comprises an illustrative model of a fireplace defined on the front side of the cabinet.

A cross-flow fan includes a plurality of fan blades provided to be circumferentially spaced apart from each other. The fan blade has an inner edge portion arranged on the radially inner side to/from which air flows in/out, and an outer edge portion arranged on the radially outer side to/from which air flows in/out. Fan blade has a blade surface extending between the inner edge portion and the outer edge portion. The blade surface includes a pressure surface arranged on the rotation direction side of the cross-flow fan and a suction surface arranged on the back side of the pressure surface. When cut along a plane orthogonal to the rotation axis of the cross-flow fan, the fan blade has a blade cross-sectional shape in which a concave portion concave from the pressure surface is formed.
