A diagnosis control method of an air conditioner is provided to clearly inform a user of an air conditioner installation error. The diagnosis control method includes receiving a test run command or a self-diagnosis command for diagnosis of the air conditioner, performing a first test run to diagnose an assembly state of the air conditioner, performing a second test run to diagnose pipe connection of the air conditioner and an amount of refrigerant in the air conditioner, performing a determination including diagnosing a state of the air conditioner based on operation results of the first test run and the second test run, and displaying the diagnosis result through a display device provided at an indoor unit of the air conditioner.

Diagnosis control method of air conditioner

An air conditioner of the disclosure includes a compressor; an indoor heat exchanger temperature sensor configured to sense an indoor heat exchanger temperature; an indoor humidity sensor configured to sense indoor humidity; and a controller configured to calculate a dew point temperature using the humidity value detected by the indoor humidity sensor and an indoor set temperature, and control a frequency of the compressor based on the calculated dew point temperature and the indoor heat exchanger temperature.

Air conditioner and method of controlling air conditioner

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 and a control method thereof perform cooling through an outlet if room temperature or room humidity is high to reduce the room temperature or the room humidity, and closing the outlet to perform cooling at low velocity through an outlet hole if room temperature or room humidity reaches a predetermined value so that a user can little feel the wind velocity of cooling of the air conditioner, while maintaining indoor space at pleasant temperature or humidity. By performing cooling at low velocity through the outlet hole formed in the lower portion of the air conditioner, it is possible to cool the lower area of indoor space at pleasant temperature when a user is asleep.

Air conditioner and control method thereof

An air conditioner and a method for controlling the same are disclosed. The air conditioner implements a multistage expansion scheme by implementing serial connection between electronic expansion valves including in the R410A refrigerant-based air conditioner, and thus guarantees an optimum compression ratio in all cooling/heating load regions. Therefore, although cycle characteristics are changed by changing R410A refrigerant to R32 refrigerant, the air conditioner optimizes the cycle simply by controlling a degree of opening of electronic expansion valves, respectively. As described above, since the cycle optimization is implemented using the multistage expansion scheme in which legacy electronic expansion valves are coupled in series, the design modification is minimized without design modification of requisite constituent elements such as a heat exchanger, system implementation is facilitated, resulting in high efficiency in cost and productivity. Cooling/heating performance improvement and reliability guarantee are achieved under all load conditions, resulting in increased system efficiency.

Air conditioner and method for controlling the same

An air conditioner and a method for controlling the same are disclosed. The air conditioner includes a compressor; an indoor fan configured to blow an indoor air; and a controller configured to change and control a revolutions per minute (RPM) of the indoor fan to a predetermined time when the compressor is off.

An air conditioner and a method for controlling the same are disclosed. The air conditioner is able to operate in an efficient cooling cycle while simultaneously guaranteeing superior cooling performance in a low-temperature operation region. In the air conditioner, an airflow directing apparatus, which is installed in an outdoor unit, suppresses not only natural convection of the air, but also heat exchange between the condenser and outdoor air by the blowing fan, such that the air conditioner forms a normal cooling cycle by guaranteeing condenser pressure. The air conditioner guarantees cooling performance of a low-temperature operation region by adjusting the amount of outdoor air flowing through blade control of the airflow directing apparatus, and operates in an efficient cooling cycle, resulting in acquisition of compressor reliability.

An air conditioner maintains a pleasant indoor temperature or humidity without making a user feel wind speed. The air conditioner includes a housing comprising a discharge plate having a plurality of discharge holes and an outlet, a heat exchanger configured to exchange heat with air introduced into the housing, a blower fan configured to allow the heat-exchanged air to flow through the discharge plate or the outlet, a discharge blade having a plurality of blade holes and configured to open and close the outlet; and a controller configured to control the heat-exchanged air to be discharged through the discharge holes and the blade holes when the outlet is closed and configured to reduce a frequency of a compressor to a predetermined value when an indoor relative humidity is within a predetermined range.
