    摘要: Scroll compressor designs are provided to minimize vibration, sound, and noise transmission. The scroll compressor has a bearing housing, and orbiting and non-orbiting scroll members. The non-orbiting scroll member has a radially extending flanged portion with at least one aperture substantially aligned with the axially extending bore. At least one fastener is disposed within the aperture and the bore. A sound isolation member contacts at least one of the non-orbiting scroll member, the fastener, or the bearing housing, to reduce or eliminate noise transmission. The sound isolation member may be formed of a polymeric composite having an acoustic impedance value greater than the surrounding materials. The sound isolation member may be an annular washer, an O-ring, or a biasing member, by way of non-limiting example. In other variations, fluid passages are provided within the fastener and/or bearing housing to facilitate entry of lubricant oil to further dampen sound and noise.

    摘要: A refrigerated food container system includes a container defining an inner volume and a thermoelectric module arranged in thermal contact with at least one surface of the container. The thermoelectric module includes a first thermoelectric cooling device and a second thermoelectric cooling device in thermal contact with the first thermoelectric cooling device. A control module is configured to provide a first voltage to the first thermoelectric cooling device and provide a second voltage to the second thermoelectric cooling device.

    摘要: A refrigeration system includes first and second compressors, a condenser, first and second evaporators, and a valve. The first compressor is fluidly connected to first suction and discharge lines. The second compressor is fluidly connected to second suction and discharge lines. The second suction line is fluidly connected to the first discharge line. The condenser receives refrigerant from the second compressor. The first evaporator receives refrigerant from the condenser and discharges refrigerant to the first suction line. The second evaporator receives refrigerant from the condenser and discharges refrigerant to the second suction line. The valve is disposed between the first evaporator and the first suction line. The first suction line receives refrigerant when the valve is in a first position. The second suction line receives refrigerant when the valve is in a second position. The first compressor is bypassed when the valve is in the second position.
