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 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.
