摘要： According to the present invention, a heat exchanger comprises a plurality of coolant tubes and a coolant guide having a coolant flow path through which the plurality of coolant tubes communicate with each other, wherein the coolant guide includes a plurality of plates facing each other, wherein the pair of plates, respectively, include coolant flow path units formed facing each other, the coolant flow path unit forming the coolant flow path, and wherein the pair of plates, respectively, further include joining parts that come in surface contact with each other. Accordingly, the number of parts of the coolant guide may be minimized, and the structure of the heat exchanger may be simplified.

摘要： 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.

摘要： 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.
