Abstract: A sensor module includes a sensor configured to sense gas in air, a load resistor connected to the sensor, and a processor configured to determine a gas concentration of the gas in the air based on an internal resistor of the sensor and the load resistor. The processor is configured to obtain an electrical conductivity change amount of the sensor and adjust a load resistance value of the load resistor based on the electrical conductivity change amount.

Abstract: According to the present invention, a heat exchanger comprises a coolant tube, and a fin having a collar coupled with the coolant tube and projected from a plate part, wherein the collar includes a call connection non-contacting part having an inner diameter larger than an outer diameter of the coolant tube, the call connection non-contacting part not contacting an outer surface of the coolant tube, and a call connection contacting part, an inner surface of the call connection contacting part contacting the outer surface of the coolant tube when the coolant tube is inserted, wherein a connecting member is positioned between an inner surface of the call connection non-contacting part and the outer surface of the coolant tube. Accordingly, without a tube expanding process for tube expanding the coolant tube, the coolant tube may be brought in tight contact with the fin. Further, the furnace brazing process is performed to minimize the defect rate.

Abstract: An air conditioner includes a suction panel including a suction grille that defines a suction port configured to receive air, an heat exchanger and a fan that are positioned within the case, and an ion generator disposed in the suction panel and configured to generate ions in the air received through the suction port. The suction panel defines an installation groove recessed from an upper surface of the suction panel and configured to receive the ion generator therein. The ion generator is accommodated inside the installation groove and configured to provide ions toward the upper surface of the suction panel in an upward direction that defines a preset angle with respect to the suction panel.
