In an air-conditioning system, a gaseous refrigerant remaining in a reservoir can be discharged from the reservoir even when a cooling operation has started and the reservoir is being filled with a liquid refrigerant. Therefore, the reservoir can be filled with the liquid refrigerant at a faster speed.

Air-conditioning system

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

A heat pump performs a simultaneous air-conditioning and heating operation through the addition of a flow path switching apparatus. The heat pump may include a plurality of outdoor units, a plurality of indoor units, and a plurality of flow path switching apparatuses that switch a flow path between an outdoor unit and an indoor unit. A refrigerant flow path may be formed from the outdoor unit to the indoor unit via a high-pressure gas pipe. The flow path switching apparatuses may switch a flow path so that a refrigerant flow path is formed from the indoor unit to the outdoor unit via a low-pressure gas pipe. The heat pump may further include an indoor unit mode controller that is connected to the plurality of outdoor units through a liquid pipe, and which is connected to each of the plurality of flow path switching apparatuses.

Heat pump and flow path switching apparatus

An air conditioner of the present invention includes: an outdoor unit having an outdoor heat exchanger and a compressor installed therein; a plurality of indoor units connected to the outdoor unit and having an indoor heat exchanger installed therein; a four-way valve provided on a discharge part side of the compressor; a refrigerant tube having first to third refrigerant tubes and connecting the four-way valve and the indoor heat exchanger, in which the first refrigerant tube is branched from between the four-way valve and the outdoor heat exchanger such that some of a refrigerant discharged from the compressor is fed into the indoor heat exchanger while bypassing the outdoor heat exchanger, the second refrigerant tube is connected to the four-way valve to feed all of the refrigerant discharged from the compressor into the indoor heat exchanger, and the third refrigerant tube is connected to the second refrigerant tube in parallel; and a heat pump valve provided at the third refrigerant tube to selectively close the third refrigerant tube. The air conditioner includes an outdoor unit that can be applied to simultaneous cooling and heating concurrent type air conditioners and cooling and heating switching type air conditioners through the opening and closing of the heat pump valve.

Air conditioner with user control between simultaneous heating and cooling operation and alternating heating and cooling operation

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
