Abstract: Disclosed is an air conditioner. The air conditioner of the present disclosure includes: an outdoor unit; at least one indoor unit configured to cool and heat an indoor space while repeating operation (Thermo-ON) and operation stop (Thermo-OFF); a sensor unit configured to measure a temperature and humidity of each indoor space where the at least one indoor unit is located; and a controller, wherein the controller calculates a sensible heat load and a latent heat load of each indoor space, based on a time when the operation stop occurs, a time when the operation starts again after the operation stop occurs, and temperature and humidity information of each indoor space, derives target sensible heat and target latent heat based on the calculated sensible heat load and latent heat load, and derives a target refrigerant temperature and an air volume of the at least one indoor unit based on the target sensible heat and the target latent heat. Accordingly, indoor sensible heat and latent heat loads can be accurately derived, and the operation efficiency of the air conditioner can be improved.

Abstract: An air conditioner is provided. The air conditioner may include a compressor, an outdoor heat-exchanger, an indoor heat-exchanger, a converter valve, an accumulator, an accumulator jacket, and a supercooling heat-exchange hub. The accumulator jacket may be disposed on a surface of the accumulator and contain a refrigerating fluid flowing therein. The refrigerating fluid may exchange heat with the accumulator to be cooled. The supercooling heat-exchange hub may be connected to the accumulator jacket to store the cooled refrigerating fluid and overcool the refrigerant flowing between the outdoor heat-exchanger and the indoor heat-exchanger.
