    摘要: A scroll compressor includes a feature for location of a housing shell section off of one of the scroll compressor bodies. According to this aspect, a scroll compressor comprises a housing including a shell section; scroll compressor bodies having respective bases and respective scroll ribs that project from the respective bases and which mutually engage about an axis for compressing fluid; and a drive unit operative to facilitate relative movement between the scroll compressor bodies. The shell section is located axially relative to a remainder of the housing off of one of the scroll compressor bodies.

    摘要: A refrigerant vapor compression system includes a flash tank receiver disposed in the refrigerant circuit intermediate the refrigerant cooling heat exchanger and the refrigerant heating heat exchanger. The flash tank receiver, which receives a liquid/vapor refrigerant mix, also functions as a receiver. A refrigerant charge control apparatus includes at least one sensor for sensing an operating characteristic of the refrigerant circulating through the refrigerant compression device, and a controller operative to selectively adjust a secondary expansion device to increase or decrease the flow of refrigerant passing into the flash tank receiver to provide a circulating refrigerant charge consistent with maintaining a desired system operating characteristic. The sensed operating characteristic is at least one of (a) the vapor refrigerant passing through a refrigerant line from the flash tank receiver to an intermediate pressure stage of the compression device, and (b) the refrigerant discharged from the compression device.
