    Abstract: An air conditioner may provide a fan housing assembly that moves in the front-rear direction by the operation of an actuator, and the fan housing assembly moves so as to pass through a front outlet arranged on a door assembly to be in a projected state, and the front end of the fan housing assembly protrudes further to the front than the front surface of the door assembly; and through the projected state, may provide conditioned air by a direct air flow to a long-distance target region. The configuration may enable the minimization of interference between the discharged air and the door assembly, and the minimization of flow loss of the discharged air since, when the fan housing assembly is in the projected state, a steering grill is in a state of protruding to the outside of the door assembly by passing through the front outlet.

    Abstract: A ventilator includes: a refrigerant circuit through which a refrigerant flows and that includes a compressor, a first heat exchanger, and a second heat exchanger that are connected by a refrigerant pipe; an air supply fan that supplies air from an outdoor space to an indoor space through the first heat exchanger; a first casing that accommodates the first heat exchanger and the air supply fan; an exhaust fan that exhausts air from the indoor space to the outdoor space through the second heat exchanger; a second casing that accommodates the second heat exchanger and the exhaust fan; and a third casing that accommodates the compressor. The first casing is separable from the second casing. The third casing is separable from the first casing and the second casing.

    Abstract: An industrial heat exchange system includes a cooling tower having an exterior wall and a top aperture. An exhaust fan is positioned near the top aperture. A mixing space of the cooling tower is positioned below the exhaust fan. An ambient air inlet extends through the exterior wall for providing outside air into the mixing space. A manufacturing air inlet extends through the exterior wall for providing heated air into the mixing space. The outside air and the heated air combine within the mixing space to define control air that is maintained above a minimum temperature. The heated air is delivered through an air duct extending from a manufacturing facility to the manufacturing air inlet.

    Abstract: A blower includes a motor with variable rotational speed, and a first controller. The motor has a shaft supported by a bearing with a lubricant sealed in. The first controller rotationally drives the motor. The first controller executes first control to decrease the rotational speed of the motor when a first temperature, which is the temperature of the bearing, decreases during operation in which the motor is rotated in a predetermined low rotational speed range. This air conditioner includes: an indoor unit having the blower, a temperature sensor that measures the first temperature, and a heat exchanger; and a second controller that controls the blower to perform air conditioning operation in a space to be air-conditioned in which the indoor unit is installed.

    Abstract: A blower includes: an outside/inside air box into which outside air and inside air are introduced; an impeller to suck and blow out air introduced into the air box; a casing having a bell mouth that forms an air suction port to the impeller, the casing forming a ventilation passage on an outer side of the impeller in a radial direction; and a plate-shaped member provided with a predetermined gap relative to the casing and the bell mouth. A gap passage is defined between the casing and the plate-shaped member. A guide rib is provided at a part of the gap passage opposite to an opening through which air flows into the gap passage. The guide rib guides air flowing through the gap passage in a circumferential direction of the bell mouth.
