Abstract: A back pressure chamber forming portion forms a back pressure chamber configured to accumulate a high pressure refrigerant discharged from a working chamber and thereby generate a refrigerant pressure, which urges a movable scroll against a stationary scroll. A balancer is placed at an inside of the back pressure chamber and is configured to be rotated by a rotatable shaft. The back pressure chamber forming portion has a discharge hole that communicates between a radially outer side of the back pressure chamber, which is located radially outward in a radial direction of an axis of the rotatable shaft, and a suction chamber to discharge a liquid phase refrigerant from the back pressure chamber into the suction chamber when the liquid phase refrigerant flows from the working chamber into the back pressure chamber.

Abstract: A centrifugal blower assembly including a ring-shaped planar portion and a sloped guide surface. The ring-shaped planar portion defines a central aperture at which a centrifugal fan is seated. The ring-shaped planar portion is elevated relative to a lower surface of a scroll casing. The sloped guide surface is between the ring-shaped planar portion and the lower surface of the scroll casing. The sloped guide surface slopes towards the lower surface, and extends in a downstream direction towards a partition of the scroll casing at a scroll starting position of the scroll casing.
Abstract translation: 一种离心风机组件，包括环形平面部分和倾斜导向表面。 环形平面部分限定了离心风扇就座的中心孔。 环形平面部分相对于涡旋壳体的下表面升高。 倾斜的引导表面位于环形平面部分和涡旋壳体的下表面之间。 倾斜的引导表面朝着下表面倾斜，并且在涡旋壳体的涡卷起始位置处沿着下游方向朝着涡旋壳体的分隔件延伸。

Abstract: An air conditioner for a vehicle includes a vapor compression refrigeration cycle switchable between a heat pump cycle and a cooler cycle, a heat core configured to heat air to be blown into a vehicle compartment by using coolant of an engine of the vehicle as a heat source, and a controller configured to control operation of the vapor compression refrigeration cycle. The controller controls the vapor compression refrigeration cycle to be operated as the cooler cycle so as to perform a defrosting control of the outdoor heat exchanger, and outputs an operation request signal to the engine, when the controller determines that the outdoor heat exchanger is frosted.
