Abstract: A climate-control system includes a variable-capacity compressor, an outdoor ambient temperature sensor, a user-controlled device, and a control module. The outdoor ambient temperature sensor indicates a temperature of outdoor ambient air. The user-controlled device provides a demand signal indicating a demand for at least one of heating and cooling. The control module commands a compressor stage and a stage run time based on the temperature from the outdoor ambient temperature sensor and the demand signal. The control module also modifies a lockout threshold based on a cycle run time, where the cycle run time is an actual run time for the compressor to meet a setpoint temperature.

Abstract: A system may include a compressor, a first passageway, a valve and a control module. The compressor includes a compression mechanism operable to compress a working fluid. The first passageway is in fluid communication with an oil sump of the compressor and the compression mechanism. The valve is disposed along the first passageway and movable between an open position allowing lubricant from the oil sump to flow to the compression mechanism and a closed position restricting lubricant from the oil sump from flowing to the compression mechanism. The control module is in communication with the valve and configured to move the valve between the closed position and the open position based on an operating parameter indicative of a temperature of the compression mechanism.

Abstract: A compressor may include a shell, a first scroll, and a second scroll. The shell may include a first inlet, a second inlet, and an outlet. The first scroll may include a first end plate and a first spiral wrap. The second scroll may include a second end plate and a second spiral wrap, the first and second spiral wraps cooperating to define a series of moving compression pockets therebetween. The moving compression pockets decrease in volume as the moving compression pockets move from a radially outer position to a radially inner position. The moving compression pockets may receive working fluid from the first inlet at the radially outer position and provide working fluid to the outlet at the radially inner position. The second end plate may include a fluid cavity receiving working fluid from the second inlet and fluidly isolated from working fluid within the moving compression pockets.

Abstract: A compressor is provided and may include a shell, a main bearing housing disposed within the shell, a driveshaft, a non-orbiting scroll member, and an orbiting scroll member. The driveshaft may be supported by the main bearing housing. The non-orbiting scroll member may be coupled to the main bearing housing and may include a first lubricant supply path in fluid communication with a lubricant source. The orbiting scroll member may be rotatably coupled to the driveshaft and may be meshingly engaged with the non-orbiting scroll member. The orbiting scroll member may include a recess that is moved between a first position in fluid communication with the first lubricant supply path and a second position fluidly isolated from the first lubricant supply path.

Abstract: Systems and methods for compressor unloading detection are provided and include a compressor having a compression mechanism. A controller determines a predicted discharge temperature of the compressor, receives an actual discharge temperature of the compressor, and compares the predicted discharge temperature with the actual discharge temperature. The controller also compares a speed of the compressor with a speed threshold and detects unloading of the compression mechanism based on the comparison of the predicted discharge temperature with the actual discharge temperature and based on the comparison of the speed of the compressor with the speed threshold. The controller performs at least one of generating an alert and a remediating action in response to detecting the unloading of the compression mechanism.

Abstract: Systems and methods that detect a loss of charge associated with a climate controlled environment are described in the present disclosure. In various embodiments, a controller receives operating condition parameters associated with a climate-controlled environment. The controller determines whether a compressor is operating in a first mode of operation or a second mode of operation. The controller applies a first model to the operating condition parameters when the compressor is operating in the first mode of operation to represent a loss of charge associated with the climate-controlled environment and applies a second model to the operating condition parameters when the compressor is operating in the second mode of operation to represent the loss of charge associated with the climate-controlled environment.

Abstract: An electrochemical climate control system circulates a working fluid comprising ammonia (NH3) and hydrogen (H2). An evaporator volatilizes liquid ammonia for a refrigeration effect. An electrochemical device can increase a total pressure of the working fluid and/or a first partial pressure of ammonia and decrease a second partial pressure of hydrogen when an f is applied. A condenser cools the working fluid/transforms ammonia to a liquid. A separator separates liquid ammonia from gas phase hydrogen. A heat exchanger may be provided downstream of the evaporator. The system may include an ejector combining vapor phase ammonia and gas phase hydrogen in a pressurized stream. A second electrochemical device is optionally included that decreases a pressure of gas phase hydrogen exiting the separator and which generates electrical potential that is transferred to the first electrochemical device. Such high efficiency systems may be free of any mechanical pumps or moving parts.
