Abstract:
A compressor includes a shell formed from a piece of material having first, second, third, and fourth ends. The third and fourth ends extend between the first and second ends and are coupled to one another. The first and second ends form longitudinal ends of the shell. The first end includes an edge having first and second protrusions extending longitudinally outwardly therefrom. The edge includes a stepped region at a location where the third end extends longitudinally beyond a portion of the edge proximate the fourth end. A partition abuts the first and second protrusions, is coupled to the shell at the first end, and includes an opening therethrough. A compression mechanism is supported within the shell and includes a discharge passage in communication with the opening in the partition.
Abstract:
A compressor may include a shell, a compression mechanism, a motor, a base member, and a mounting foot. The compression mechanism may be disposed within the shell and the motor may be drivingly engaged with the compression mechanism. The base member may be coupled to the shell and a mounting foot may be fixed to the base member. The mounting foot may include a mounting aperture extending therethrough and a slot intersecting said aperture that attenuates vibrations within an operating frequency range of the compressor.
Abstract:
A flash tank for a heat pump operable in a heating mode and a cooling mode includes a shell having a middle portion disposed between a top portion and a bottom portion, with the top portion, bottom portion, and middle portion cooperating to define an inner volume of the shell. A first port is in fluid communication with the inner volume and functions as an inlet in the heating mode and as an outlet in the cooling mode. A second port is in fluid communication with the inner volume and functions as an inlet in the cooling mode and as an outlet in the heating mode. Flow control devices and check valves are fluidly coupled to control the tank as a flash tank in heating mode and as a receiver in cooling mode.
Abstract:
A floating seal has a lower plate, an upper plate and a pair of seals disposed between the two plates. The lower plate, the upper plate or both plates include a backer which projects outward from the plate to engage one or both of the seals to support the seal during operation.
Abstract:
A vapor-compression circuit may be used to meet the temperature/load demands for conditioning one or more spaces. Excess heat generated in the vapor-compression circuit may be utilized to generate an electric current that may power other components of the vapor-compression circuit. A thermoelectric device may be placed in heat-transferring contact with the excess heat and generate the electrical current. The electric current generated may be used to power another thermoelectric device to provide further cooling or heating of a fluid in heat-transferring relation therewith to supplement the vapor-compression circuit and the conditioning of the space.
Abstract:
A heating and cooling (HVAC) system that includes a compressor; a first heat exchanger; a second heat exchanger; a first expansion valve positioned between the first heat exchanger and the second heat exchanger; a first reversing valve that permits the system to operate in a first mode and a second mode; and a thermal battery including a phase change material therein that is configured to selectively store and release thermal energy received from a working fluid.
Abstract:
A compressor includes a shell, a first compression member, a bearing housing and a second compression member. The first compression member is rotatable relative to the shell about a first axis. The bearing housing is coupled to the first compression member and rotatable relative to the shell about the first axis. The bearing housing includes a first pin that extends therefrom. The second compression member is rotatable relative to the shell about a second axis. The second compression member includes a base plate and an arcuate-shaped first pin pocket. The first pin pocket is formed in the base plate and receives the first pin. The first compression member is moveable between a first position in which the first pin is engaged with a surface of the first pin pocket and a second position in which the first pin is disengaged from the surface of the first pin pocket.
Abstract:
A compressor may include first and second scrolls, an axial biasing chamber, and a modulation control valve. The second scroll includes an outer port and an inner port. The outer and inner ports may be open to respective intermediate-pressure compression pockets. The modulation control valve may be in fluid communication with the inner port, the outer port, and the axial biasing chamber. Movement of the modulation control valve into a first position switches the compressor into a reduced-capacity mode and allows fluid communication between the inner port and the axial biasing chamber while preventing fluid communication between the outer port and the axial biasing chamber. Movement of the modulation control valve into a second position switches the compressor into a full-capacity mode and allows fluid communication between the outer port and the axial biasing chamber while preventing fluid communication between the inner port and the axial biasing chamber.
Abstract:
A compressor includes a shell, a bearing housing, an orbiting scroll, a non-orbiting scroll and a spacer. The bearing housing includes a central body and a plurality of arms extending radially outwardly from the central body. Each of the arms has a first aperture. The non-orbiting scroll is meshingly engaged with the orbiting scroll and includes a plurality of second apertures. Each second aperture receives a bushing defining a first longitudinal axis and a fastener defining a second longitudinal axis. The fastener extends through the bushing and into a corresponding one of the first apertures in the bearing housing. The spacer is disposed between the bushing and the fastener of each second aperture and is configured to engage one of the bushing and the fastener to restrict radial misalignment between the first longitudinal axis of the bushing and the second longitudinal axis of the fastener.
