Abstract:
A compressor includes a shell, a compression mechanism, a motor, a base member, and a mounting foot. The compression mechanism is disposed within the shell and the motor is drivingly engaged with the compression mechanism. The base member is coupled to the shell and a mounting foot is fixed to the base member. The mounting foot includes a mounting aperture extending therethrough and a slot intersecting the aperture that attenuates vibrations within an operating frequency range of the compressor.

Abstract:
A system and method for calculating parameters for a refrigeration system having a variable speed compressor is provided. A compressor is connected to a condenser and an evaporator. An evaporator sensor outputs an evaporator signal corresponding to at least one of an evaporator pressure and an evaporator temperature. An inverter drive modulates electric power delivered to the compressor to modulate a speed of the compressor. The control module is connected to the inverter drive and receives the evaporator signal, monitors electrical power data and compressor speed data from said inverter drive, and calculates at least one of a condenser temperature and a condenser pressure based on the evaporator signal, the electrical power data, and the compressor speed data.

Abstract:
sistemas de aquecedor de cárter e métodos para compressores de velocidade variável. a presente invenção refere-se a um sistema que inclui um compressor tendo uma carcaça alojando um mecanismo de compressão acionado por um motor elétrico em um estado ligado e não acionado pelo motor elético em um estado desligado. o sistema também inclui um acionamento de frequência variável que aciona o motor elétrico no estado ligado pela variação de uma frequência de voltagem entregue ao motor elétrico e que supre corrente elétrica para um estator do motor elétrico no estado desligado para aquecimento do compressor.
Abstract:
A system includes a compressor having a shell housing a compression mechanism driven by an electric motor in an on state and not driven by the electric motor in an off state. The system also includes a variable frequency drive that drives the electric motor in the on state by varying a frequency of a voltage delivered to the electric motor and that supplies electric current to a stator of the electric motor in the off state to heat the compressor.

Abstract:
A counterweight cover for a compressor is provided and may include an annular body having a recess at least partially defined by an outer circumferential portion, an inner circumferential portion, and an upper portion connecting the outer circumferential portion and the inner circumferential portion. A suction baffle may be disposed on the annular body and may direct a flow of suction gas within the compressor.
