摘要： An evaporator blower for air conditioning system that can be installed into a ceiling between existing joists. The system has a chassis dimensioned to fit between the pair of joists forms an air flow pathway through which air may be cooled by an evaporator housed in the chassis. A mounting flange is pivotally coupled to the chassis and has an opening through which the chassis can pivot between a first position below the mounting flange, and thus the ceiling, to a second position above the flange, so that the chassis is above the ceiling and between the pair of joists. A diffuser is attached to the mounting flange and provides supply and return air grilles that are in fluid communication with the air flow pathway of the chassis.

摘要： An air conditioning system capable of reducing noise incidental to gas-liquid two-phase transfer is provided. The air conditioning system (100) performs a refrigeration cycle in a refrigerant circuit (RC) including an outdoor unit (10), a plurality of indoor units (40), and a liquid-side connection pipe (LC) connecting the outdoor unit (10) and the indoor units (40). The air conditioning system (100) includes a second outdoor control valve (17, electric valve) decompressing the refrigerant flowing in the refrigerant circuit (RC) in accordance with an opening degree, an operating-capacity variation detection portion (74, detection portion) detecting change of the number of operating units in accordance with device information, and a device control portion (75, control portion) controlling a state of the second outdoor control valve (17). The device control portion (75) executes first control (feed-forward control) when the change of the number of operating units is detected by the operating-capacity variation detection portion (74), and adjusts the opening degree of the second outdoor control valve (17) to suppress a rise of pressure of the refrigerant flowing into the operating unit.

摘要： A centrifugal blower having high efficiency and reduced noise is provided. A centrifugal blower to be accommodated in a housing having an air inlet includes a spiral casing having a bell mouth and a centrifugal fan housed in the casing. The bell mouth includes a first region and a second region. The first region is disposed closest to the air inlet. A distance from a rotational axis of the centrifugal fan to a downstream end in the first region is greater than a distance from the rotational axis to the downstream end in the second region. A curvature of a surface of the first region in a cross section including the rotational axis is smaller than a curvature of a surface of the second region in a cross section including the rotational axis.
