Abstract: An air conditioner including: a compressor; a heat exchanger fluidly connected to the compressor; a pressure sensor provided in a first flow path connecting an outlet of the compressor to an inlet of the first heat exchanger; a temperature sensor provided in a second flow path connected to an outlet of the heat exchanger; and a processor connected to the compressor, the pressure sensor, and the temperature sensor. The processor configured to: acquire a reference index value based on a first reference pressure measured by the pressure sensor and a first reference temperature measured by the temperature sensor, acquire a measurement index value based on a first measurement pressure measured by the pressure sensor and a first measurement temperature measured by the temperature sensor, and display a shortage of a refrigerant of the air conditioner based on the reference index value and the measurement index value.

Abstract: An air conditioner, and a method of controlling the air conditioner, including a compressor configured to compress a refrigerant, and including a discharge port; an outdoor heat exchanger configured to exchange heat with outside air, and including an upper portion including an upper inlet, and a lower portion including a lower inlet; a first four-way valve arranged between the discharge port of the compressor and the upper inlet; a second four-way valve arranged between the discharge port of the compressor and the lower inlet; and a controller electrically connected to the compressor, the first four-way valve and the second four-way valve. The controller may be configured to control the first four-way valve and the second four-way valve to perform a first defrosting operation which defrosts the upper portion and the lower portion during a heating operation, and control the first four-way valve and the second four-way valve to perform a second defrosting operation which operates the upper portion as an evaporator, and operates the lower portion as a condenser, based on a need for additional defrosting of the lower portion being detected.

Abstract: Provided are an air conditioning device and method. The air conditioning control device includes a ventilation fan, a memory storing at least one instruction, and at least one processor connected to the memory, in which the at least one processor is configured to, by executing the at least one instruction, determine, among a plurality of rooms, a first room from which thermal energy is to be recovered and a second room to which the thermal energy to be recovered is to be supplied, based on at least one of a sensor value of a sensor in a room among the plurality of rooms, a use schedule of at least one room among the plurality of rooms, and a user input, and drive the ventilation fan to exchange thermal energy of the first room and thermal energy of the second room.
