    Abstract: A heat-pump circuit may include an indoor heat exchanger, an outdoor heat exchanger, a compressor adapted to circulate a working fluid between the indoor and outdoor heat exchangers, and an expansion device disposed between the indoor and outdoor heat exchangers. A monitor for the heat-pump system may include a return-air temperature sensor, a supply-air temperature sensor, and a processor. The return-air temperature sensor may be adapted to measure a first air temperature of air upstream of the indoor heat exchanger. The supply-air temperature sensor may be adapted to measure a second air temperature of air downstream of the indoor heat exchanger. The processor may be in communication with the return-air temperature sensor and the supply-air temperature sensor. The processor may be programmed to determine a working-fluid-charge condition of the heat-pump system based on the first and second air temperatures.

    Abstract: A compressor is provided and may include a shell having an inner surface and an outer surface and a bearing housing disposed within the shell and having an engagement surface opposing the inner surface. The engagement surface may include a first channel formed substantially perpendicular to a longitudinal axis of the shell and a second channel formed substantially parallel to the longitudinal axis of the shell and in communication with the first channel. The first channel and the second channel may receive a deformed portion of the shell therein to fix a position of the bearing housing relative to the shell.

    Abstract translation: 提供压缩机，并且可以包括具有内表面和外表面的壳体和设置在壳体内并具有与内表面相对的接合表面的轴承壳体。 接合表面可以包括基本上垂直于壳体的纵向轴线形成的第一通道和形成为基本上平行于壳体的纵向轴线并与第一通道连通的第二通道。 第一通道和第二通道可以在其中容纳壳体的变形部分以固定轴承壳体相对于壳体的位置。
