Abstract: Provided is an air conditioning system including: a case including a first sub-case including an outdoor air inlet and a discharge outlet, and a second sub-case including an air returning inlet and an air supply inlet; a desiccant rotor module; a heat exchanger including a first sub-heat exchanger and a second sub-heat exchanger, a ventilator including a first sub-ventilator and a second sub-ventilator; and a damper including a first sub-damper and a second sub-damper, wherein the first sub-damper is installed downstream of the first region of the desiccant rotor module, and the second sub-damper is installed downstream of the second region of the desiccant rotor module, wherein the desiccant rotor module and the heat exchanger are integrally assembled so as to be detachably installed in the case, wherein the outdoor air and the indoor air do not mix with each other.

Abstract: An electronic device and a method of operating the electronic device are provided. The method includes sensing a weight of an intravenous (IV) fluid injected into a user; measuring a time remaining until injection of the IV fluid is completed, based on the sensed weight of the IV fluid; determining whether the measured remaining time is equal to or less than a predetermined value; and transmitting an alarm signal indicating an injection state of the IV fluid to an external device based on a result of the determining.
