摘要:
An indoor unit for an air conditioning apparatus is provided. The indoor unit includes a cross flow fan having a structure that can reduce noise and flow resistance of air passing through a heat exchanger in the indoor unit.
摘要:
An air conditioner includes a fan and a rear guide which guides air to the fan. A recess is formed in a side surface of the rear guide which faces the fan.
摘要:
A cross-flow fan that variably maintains a distance between a blade and a fluid flow guide by varying a height of an outer edge and an air conditioner having the cross-flow fan are provided. Therefore, a noise and a peak value of a spectrum between the blade and the outer edge can be reduced.

摘要:
An air conditioner, in which a controller is installed separately from a plurality of indoor units and a plurality of outdoor units so that only the controller is added and conventional outdoor units are used when plural indoor units are required, thereby reducing costs due to the omission of other outdoor units. The controller determines whether or not the outdoor units are respectively operated according to a signal of a temperature sensing unit, and selectively operates the outdoor units according to a required capacity, thereby increasing the operating efficiency of the air conditioner.
摘要:
An outdoor unit for an air conditioner is disclosed, the outdoor unit characterized by: a case (100) formed with an air suction port (110) sucking air from outside and an air discharge port (120) discharging the sucked air; a first blowing fan (200) formed inside the case (100) for discharging the air sucked from the air suction port (110) to the air discharge port (120); and a second blowing fan (300) formed inside the case (100) and positioned on the same axis of the first blowing fan (200) for rotating in an opposite direction of the first blowing fan (200), such that generation of cavitation of a blowing fan is limited to greatly reduce noise and vibration.

摘要:
A unitary air conditioner comprises a 1-stage thermostat mounted in a room for generating an air conditioner ON/OFF signal, an indoor unit configured to operate based on a signal from the 1-stage thermostat, and a variable-capacity outdoor unit connected to the 1-stage thermostat and the indoor unit. The variable-capacity outdoor unit has variable operation stages, which are changed based on the previous operation state and the current operation state. When a unitary-capacity operation signal is inputted from the 1-stage thermostat, a start operation stage of an outdoor unit is determined based on the combination of the operation stage of the outdoor unit operated before the operation signal is inputted and the operation time in the stage, and the determined operation is performed. The 1-stage thermostat can be connected to the variable-capacity outdoor unit according to circumstances.
摘要:
A unitary air conditioner comprises a 1-stage thermostat for generating an operation signal for the unitary air conditioner or a stop signal for the unitary air conditioner, a 1-stage indoor unit having an indoor fan, which is rotated according the operation signal from the 1-stage thermostat, a variable-capacity outdoor unit configured to be operated according to the 1-stage thermostat, the variable-capacity outdoor unit having a compressor and an outdoor fan, the operation stage of which is changed according to the operation state of the variable-capacity outdoor unit, and an indoor fan control device for controlling the indoor fan according to the operation stage of the variable-capacity outdoor unit to change the operation state of the indoor fan. The 1-stage indoor unit is operated along with another unit having different stages, and variable control is accomplished, although the 1-stage indoor unit is used, so long as the indoor fan control device is added to the unitary air conditioner. Consequently, a more efficient air conditioning system is accomplished.
