Abstract: 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.

Abstract: A system and method for flooded start control of a compressor for a refrigeration system are provided. A sensor generates sensed data corresponding to a condition of the refrigeration system. A control module is configured to operate the compressor in a flooded-start control mode including operating the compressor according to a cycle with a first time period during which the compressor is on and a second time period during which the compressor is off. The control module operates the compressor in an initial time period, without using the flooded-start control mode, with liquid refrigerant present in the compressor and monitors the sensed data from the sensor. The control module operates the compressor in the flooded start control mode after determining the first time period, the second time period, or a number of cycles, based on the sensed data monitored during the initial time period.

Abstract: A climate-control system includes a first working-fluid circuit, a second working-fluid circuit and a first heat exchanger. The first working-fluid circuit includes a first compressor, a second heat exchanger and a first pump. The second heat exchanger is in fluid communication with the first compressor. The first pump receives a first working fluid from the second heat exchanger and circulates the first working fluid through the first working-fluid circuit. The second working-fluid circuit is fluidly isolated from the first working-fluid circuit and includes a second pump and a fourth heat exchanger. The second pump is in fluid communication with the fourth heat exchanger. The first heat exchanger is thermally coupled with the first working-fluid circuit and the second working-fluid circuit.

Abstract: A compressor may include first and second scrolls, and an axial biasing chamber. Spiral wraps of the scrolls mesh with each other and form compression pockets including a suction-pressure compression pocket, a discharge-pressure compression pocket, and intermediate-pressure compression pockets. The axial biasing chamber may be disposed axially between the second end plate and a component. Working fluid disposed within the axial biasing chamber may axially bias the second scroll toward the first scroll. The second end plate includes outer and inner ports. The outer port is disposed radially outward relative to the inner port. The outer port may be open to a first one of the intermediate-pressure compression pockets and in selective fluid communication with the axial biasing chamber. The inner port may be open to a second one of the intermediate-pressure compression pockets and in selective fluid communication with the axial biasing chamber.

Abstract: A refrigeration system includes compressor and a duct assembly that includes a duct frame and a sensor unit. The duct frame provides a path for evaporating refrigerant from a lubricant sump of the compressor. The sensor unit obtains temperature measurements of the refrigerant and a lubricant within the lubricant sump and heats and evaporates the refrigerant located within the duct frame of the duct assembly. A control module receives temperature measurements from the sensor unit, determines a presence of liquid refrigerant within the lubricant sump of the compressor in response to a determination that an actual temperature change does not correspond with an expected temperature change for the lubricant, and in response to a determination that the actual temperature change corresponds with the expected temperature change for the lubricant, operates the compressor.

Abstract: A sensor module for a compressor having an electric motor connected to a power supply is provided. The sensor module includes: a first input connected to a first voltage sensor that generates a voltage signal corresponding to a voltage of the power supply; a second input connected to a first current sensor that generates a current signal corresponding to a current of the power supply; and a processor connected to the first and second inputs. The processor monitors the first and second inputs and, based on voltage measurements from the first input and current measurements from the second input, detects at least one of: (i) an unexpected variation of electric power from the power supply; and (ii) a mechanical malfunction. The processor is disposed within an electrical enclosure of the compressor, the electrical enclosure being configured to house electrical terminals for connecting the power supply to the electric motor.

Abstract: An expectation module determines an expected average power consumption of a heat pump for a predetermined period as a function of indoor and outdoor temperatures of the building during the predetermined period. A difference module determines a power difference between an average power consumption of the heat pump during the predetermined period and the expected average power consumption of the heat pump for the predetermined period. A grade determination module determines a grade of the heat pump for the predetermined period based on the power difference of the predetermined period. A reporting module generates a displayable report including the grade of the heat pump for the predetermined period.

Abstract: A compressor includes a non-orbiting scroll, an orbiting scroll, a driveshaft, a bearing housing and a bushing. The non-orbiting scroll includes a first spiral wrap. The orbiting scroll includes an end plate having a first side and a second side. The first side has a second spiral wrap that extends therefrom and meshingly engages with the first spiral wrap of the non-orbiting scroll. The second side has a hub extending therefrom. The driveshaft has a crankpin that is received in the hub and that drives the orbiting scroll. The bushing includes a first member and a second member. The first member is disposed within the hub of the orbiting scroll between the hub and the crankpin of the driveshaft. The second member extends radially from the first member and is disposed between the hub and the bearing housing.

Abstract: A compressor may include a housing, a piston, and a cylinder head assembly. The housing defines a cylinder and a first valve seat defining a recess. The piston is movable within the cylinder to define a compression chamber. The cylinder head assembly is mounted on the housing and includes a valve plate, a suction valve, a discharge valve and a head cover. The valve plate may be mounted to the mounting surface and may include a suction plenum, a suction passage providing fluid communication between the suction plenum and the cylinder, and a discharge passage. The suction valve can seat on the first valve seat to allow fluid flow through the suction passage. The head cover may include a discharge chamber and an integrally formed guide post extending into the discharge chamber. The guide post may include a pocket that receives a discharge valve stem for reciprocation therein.

Abstract: An ice-maker system may be operable in an ice-making mode and in an ice-harvesting mode and may include a working-fluid circuit and an ice mold. The working-fluid circuit may include a compressor, an expansion device, and an ice-making heat exchanger. The expansion device is disposed downstream of the compressor. The ice-making heat exchanger is disposed between the expansion device and the compressor along the working-fluid circuit. The ice mold includes a plurality of pockets configured to receive water from a water-supply conduit when the system is operating in the ice-making mode. The ice mold may be in a heat-transfer relationship with the ice-making heat exchanger. The ice mold may define a channel that receives a warming fluid from a warming-fluid-supply conduit when the system is operating in the ice-harvesting mode. The warming fluid is fluidly isolated from working fluid circulating through the working-fluid circuit.
