An air conditioner, a control device thereof, and a method of controlling the same are provided. The air conditioner includes a control device including a plurality of indoor unit operation changers, and an indoor unit connected to any one of the plurality of indoor unit operation changers, where at least one of the indoor unit and the control device determines an operation mode of each of the plurality of indoor unit operation changers respectively connected to a plurality of indoor units, detects an indoor unit operation changer at an operation mode corresponding to an operation of any one of the plurality of indoor units among the plurality of indoor unit operation changers, and determines an indoor unit operation changer connected to the indoor unit among the plurality of indoor unit operation changers on based on a result of detecting at least one of the indoor unit operation changers.

Air conditioner, control device thereof, and method of controlling the same

An air conditioner according to the present invention has a structure driving a compressor and a pump, simultaneously, in a low-temperature cooling environment in which the outdoor temperature is lower than the indoor temperature.

Air conditioner and control method therefor

An apparatus for detecting an oil level and a method for controlling the same, an apparatus for detecting oil flow and a method for controlling the same, and a method for controlling oil return using the detected oil level and the detected oil flow are disclosed. The level of oil stored in a compressor is measured at two or more positions. The frequency comparison scheme using two electrodes can correctly detect the level of oil stored in the compressor, a refrigerant state, and the level of mixed oils, and can determine an internal state of the compressor and a normal or abnormal state of the oil return system, such that the oil return control can be actively controlled. The flow of oil in the oil return pipe is detected so as to determine whether the oil is normally supplied in real time, such that a malfunction of the compressor is prevented and a valve state can be checked. The level of oil stored in the compressor is adjusted not only using the oil level detection result but also the oil flow detection result, and the oil return operation can be controlled.

Oil level detecting apparatus and control method thereof, oil flow detecting apparatus and control method thereof, method for control oil return using oil level and oil flow

An air conditioner, having an outdoor unit and an indoor unit, to perform a heating operation and a defrosting operation, the air conditioner including a detection unit to detect a state of at least one selected between the outdoor unit and the indoor unit and to output the detected value, a controller to determine whether the air conditioner is in a stable state when the defrosting operation is completed and, upon determining that the air conditioner is in the stable state, to control the detected value output from the detection unit to determine entry time of the next defrosting operation, and a storage unit to store a value detected in the stable state. The entry time of the defrosting operation is accurately determined, thereby minimizing the number of times of the defrosting operation during the heating operation.

Air conditioner and control method thereof

The present disclosure provides an air conditioner. The air conditioner includes a compressor; a sensor for measuring the compressors state configured to detect compressor state information that includes at least one of a pressure value and a saturation temperature of the compressor; and a controller configured to control air flow on the side of an indoor unit by comparing the compressor state information measured from the sensor and a threshold.

Air conditioner and method for controlling the same

A cooling and heating control method of a multi type air conditioner in which a target pressure of a compressor is adjusted based on conditions of respective indoor units so as to reduce power consumption is provided. The cooling control method includes determining the indoor unit desired to execute power saving control, judging whether or not a difference between a temperature of a space in which the indoor unit desired to execute power saving control is located and a set temperature of the indoor unit is less than a reference value, raising a target evaporation temperature of the indoor unit upon judging that the difference is less than the reference value, comparing an evaporation temperature of the indoor unit with the raised target evaporation temperature, and raising an evaporation pressure of a compressor, when the evaporation temperature of the indoor unit is lower than the raised target evaporation temperature.

Multi type air conditioner and cooling and heating control method thereof

A compressor capable of reducing oil foaming and reducing the waiting time taken until the heating of the compressor is completed, and a method of controlling the same, the method of controlling a compressor including sensing temperature of the oil in the compressor, if the temperature of the oil is below a reference temperature, performing a loss operation, in which an amount of heat radiation of the motor part is increased, while operating the motor part at a low speed, and if the temperature of the oil increases to be equal to or higher then reference temperature, performing an efficiency operation by converting an operation of the motor to a normal operation.

Compressor and control method thereof

An air conditioner having a plurality of compressors and a starting control method thereof, where the plurality of compressors is simultaneously started if a starting load of the air conditioner is smaller than a reference load, and the plurality of compressors is sequentially started if the starting load of the air conditioner is larger than the reference load, thereby simultaneously starting the plurality of compressors at a starting load section in which a starting stability of the compressors is secured, and thus capable of enhancing the cooling and heating performance.

Air conditioner and starting control method thereof
