Abstract: A system may include a first compressor, a second compressor, a first heat exchanger and a second heat exchanger. The first compressor has a first inlet and a first outlet. The second compressor is a sumpless compressor and has a second inlet and a second outlet. The second compressor provides working fluid discharged from the second outlet to the first compressor. The first heat exchanger is disposed upstream of the second compressor and provides working fluid to the second compressor. The second heat exchanger is disposed upstream of the first compressor and provides working fluid to the first compressor.

Abstract: An electrochemical climate control system circulates a working fluid comprising ammonia (NH 3 ) and hydrogen (H 2 ). 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.

Abstract: A compressor may include a crankcase, a crankshaft, a piston, a discharge valve and a suction plenum. The crankcase defines a discharge plenum receiving working fluid at a first pressure. The crankshaft is disposed within the discharge plenum. The piston is drivingly connected to the crankshaft and reciprocatingly received in a cylinder. The piston and cylinder cooperate to define a compression chamber therebetween. The discharge valve may control fluid flow through a discharge passage between the compression chamber and the discharge plenum. The suction plenum may receive working fluid at a second pressure that is less than the first pressure. The suction plenum may provide working fluid at the second pressure to the compression chamber.

Abstract: A compressor may include a shell, a compression mechanism supported within the shell, a drive shaft engaged with the compression mechanism and a motor. The drive shaft may define first and second passages extending axially within the drive shaft and a third passage extending radially through an outer circumferential surface of the drive shaft and in communication with the second passage. The drive shaft may define an axially extending wall separating the first and second passages. The motor may include a rotor fixed to the drive shaft and a stator supported within the shell. The third passage may be adapted to provide oil to the stator during compressor operation to cool the stator.

Abstract: A compressor includes a compression mechanism, a driveshaft, and a motor. The compression mechanism is configured to compress a fluid to a discharge pressure. The motor is configured to rotate the driveshaft. The driveshaft is engaged with the compression mechanism and is fixed to rotate with at least a portion of the compression mechanism. The driveshaft includes a longitudinal aperture configured to receive the fluid at a suction pressure, and includes a flange that receives at least a portion of the compression mechanism. The flange and the compression mechanism define a fluid passage therebetween. The fluid at suction pressure is received within the fluid passage from the longitudinal aperture in the driveshaft.

Abstract: A method for determining a mass flow of a dynamic compressor that does not include a mass flow sensor while the compressor is operating to compress a working fluid includes determining, by a processor, a current operating point of the compressor. If the current operating point is the same as one in a map of a plurality of predetermined operating points stored in a memory, the mass flow of that predetermined operating point is retrieved as the mass flow of the current operating point. Otherwise, the processor calculates the mass flow at the current operating point from the mass flows of a subset of the predetermined operating points nearest the current operating point. The dynamic compressor continues to operate to compress the working fluid based at least in part on the calculated mass flow rate for the current operating point.

Abstract: A cooling system for a compressor includes a coolant supply line, a coolant return line, a temperature sensor connected to the coolant return line to detect at least one of a temperature of the coolant return line and a temperature of coolant within the coolant return line, and a controller. The coolant supply line includes a coolant control valve, and is connectable to a housing of the compressor to deliver coolant to at least one of a plurality of coolant flow channels defined therein. The coolant return line is connectable to the compressor housing to receive coolant from the coolant flow channels and return coolant to a low-pressure side of the compressor. The controller is configured to control the coolant control valve based on the temperature detected by the temperature sensor to control the supply of coolant through the coolant supply line.
