Abstract: An air conditioner is provided that may include a case having a supply flow path formed therein and through which outside air flows into an interior space, a first heat exchanger disposed on the supply flow path, in which refrigerant flows, and that exchanges heat between the air and the refrigerant, a second heat exchanger disposed downstream of the second heat exchanger on the supply flow path, in which refrigerant selectively flows, and that exchanges heat between the air and the refrigerant, and a refrigerant distributer configured to send the refrigerant to the first heat exchanger or the second heat exchanger.

Abstract: An air conditioning system having an auxiliary heat source is provided and that may include an outdoor unit, an indoor heat exchanger connected to the outdoor unit, the indoor heat exchanger including a temperature sensor, an auxiliary heat source arranged as an auxiliary to the outdoor unit and operated by an energy source different from an energy source of the outdoor unit, a thermostat configured to control a temperature of an installation space supplied with cold air or warm air by the outdoor unit and the auxiliary heat source, and a communicator. The communicator may include an input unit connected to the thermostat, a first output unit connected to the auxiliary heat source, a second output unit connected to the outdoor unit, and a controller configured to process signals between the input unit, the first output unit, and the second output unit.

Abstract: An air conditioner may include a heat exchanger having a first cooling coil and a second cooling coil inclined toward each other, an inlet formed between a lower end of the first cooling coil and a lower end of the second cooling coil to allow air to pass through, an inside air duct through which air introduced to the inlet flows, an air supply duct through which the air passing through the heat exchanger flows, a fan causing air passing through the heat exchanger to flow, and a temperature sensor sensing a temperature of the air introduced into the heat exchanger. The heat exchanger includes a plate positioned between the first cooling coil and the second cooling coil. The plate may have a sensor insertion hole into which the temperature sensing device is inserted. By measuring the temperature of the air introduced into the heat exchanger, more accurate control information may be provided.
