Abstract: An air conditioner apparatus is disclosed. The air conditioner apparatus includes a suction channel module including a suction module housing, a first suction channel defined in the suction module housing, a second suction channel defined in the suction module housing, and a suction connection channel connected between the first suction channel and the second suction channel for guiding air, a discharge channel module including a discharge module housing for receiving air from the suction module housing, a first discharge channel defined in the discharge module housing, a second discharge channel defined in the discharge module housing, and a discharge connection channel connected between the first discharge channel and the second discharge channel for guiding air, a first heat exchanger disposed between the first suction channel and the first discharge channel for exchanging heat with air having passed through the first suction channel, the first heat exchanger being operated as one selected from between a condenser and an evaporator, and a second heat exchanger disposed between the second suction channel and the second discharge channel for exchanging heat with air having passed through the second suction channel, the second heat exchanger being operated as the other selected from between the condenser and the evaporator. Regardless of whether air is introduced through the upper part or the lower part of the suction channel, the air exchange heat with the heat exchanger while contacting the entire surface of the heat exchanger. Consequently, it is possible to perform heat exchange using the entire surface of the heat exchanger, irrespective of the suction area.

Abstract: A case for an electric motor includes a case body provided with an inner case and an outer case together forming a cooling fluid flow path penetratingly formed in an axial direction of the case body, and a circuit component mounting portion protruding from an outer surface of the outer case to mount a circuit component such that the circuit component is cooled by cooling fluid. Case covers are coupled to both end portions of the case body so that the electric motor and the circuit component can be simultaneously cooled by the single cooling fluid flow path. In this way, a separate circuit component case for mounting the circuit component can be excluded, thereby reducing a size and weight of the case.

Abstract: A ventilation apparatus includes a casing having the inside partitioned into a first floor and a second floor. A first sharing duct is formed in the first floor and configured to suck one of indoor air and outdoor air and to have the sucked air horizontally moved. A second sharing duct is formed in the second floor and configured to suck the other of indoor air and outdoor air and to have the sucked air horizontally moved. First and second heat exchangers are disposed in the first and second sharing ducts, respectively. The ventilation apparatus is advantageous in that air resistance is minimized, horizontally moving air is subject to heat exchange with the entire area of the heat exchanger, and efficiency of heat exchange between air and the heat exchanger is improved because air is divided into the first floor and the second floor and horizontally moved.
