Abstract: A scroll compressor can include a housing, a rod member, and a nut. The housing can define a first bore. The non-orbiting scroll can include a flange. The flange can define a second bore. The rod member can have a first axial end that is coupled to the housing. The rod member can extend from the first bore and through the second bore to a second axial end of the rod member. The rod member can include at least one set of external threads. The at least one set of external threads can be disposed about the second axial end of the rod member. The nut can be threadably engaged with the second axial end of the rod member. The second bore can be disposed axially between the nut and the housing. The primary forces acting within the rod member are tensile forces, while torsional shear forces are minimized.

Abstract: A system is provided and includes a first controller, a non-transitory computer- readable medium and a second controller. The first controller is configured to control operation of at least one compressor circuit including one or more compressors. The non-transitory computer-readable medium is configured to store instructions of a stage profiler for execution by the controller. The instructions include: determining a target system capacity profile for the at least one compressor circuit; determining system stage capacities for stages of the at least one compressor circuit; selecting some of the system stage capacities based on the target system capacity profile to provide an available system capacity profile; generating modulation information based on the available system capacity profile and a load request signal; and controlling operation of the one or more compressors based on the modulation information and according to the available system capacity profile.

Abstract: A system is provided that includes mode and battery modules. The mode module, based on parameters, determines whether to operate in a shore power, engine or battery mode. One or more batteries are charged based on received utility power while in the shore power mode. The batteries, while in the engine mode, are charged based on power received from a power source. The battery module, while operating in the battery mode, determines a speed based on a temperature within a temperature controlled container of a vehicle and a state of charge of the batteries. The compressor is run at the speed while in the battery mode. While in the battery mode, the batteries are not being charged based on power from a shore power source and the power source from which power is received during the engine mode.

Abstract: A system includes a converter and a controller to control a compressor and operates without receiving power supply from a thermostat. The converter receives a demand signal from the thermostat that is used to power the controller and charge a capacitor. When the thermostat de-asserts the demand signal, the charged capacitor powers the controller, which saves system parameters in a nonvolatile memory and enters a power save mode. The life of the nonvolatile memory is extended by alternately storing the system parameters in different memory locations. The system normalizes outdoor ambient temperature (OAT) during a demand cycle. The system determines OAT slope, which is used to select durations to operate the compressor at different capacities, by performing time based calculations during a demand cycle, demand cycle based calculations at the start of a demand cycle, or time and demand cycle based calculations during a demand cycle.

Abstract: A system includes a compressor, an indoor fan, a thermostat, an indoor fan controller, and a compressor controller. The thermostat provides first and second signals based on indoor loading. The fan controller operates the fan in low speed mode and the compressor controller operates the compressor in low capacity mode when only the first signal is asserted. The compressor controller automatically switches the compressor to high capacity mode if only the first signal remains asserted past the low capacity mode runtime. The fan controller operates the fan in high speed mode when the second signal is asserted while the first signal is still asserted. The compressor controller continues to operate the compressor in high capacity mode and the fan controller operates the fan in low speed mode after the second signal is de-asserted, until the first signal is de-asserted, at which point the fan and compressor are turned off.
