Abstract: A control system for controlling an output for a plurality of compressors includes a control unit receiving a first value from a first sensor and generating a first output based on the first value. The control unit receives a second value from a second sensor and derives a final output from the first output and the second value. A plurality of compressors receives the control commands from the control unit based on the final output.

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: An air conditioning system of a vehicle having an internal combustion engine includes a condenser configured to receive refrigerant output by an electric compressor and transfer heat from the refrigerant within the condenser to air passing the condenser. A first evaporator is configured to receive refrigerant from the condenser when a first control valve is open and transfer heat from air passing the first evaporator to the refrigerant within the first evaporator. A first blower is configured to blow air across the first evaporator to a first section of a cabin of the vehicle. A second evaporator is configured to receive refrigerant from the condenser when a second control valve is open and transfer heat from air passing the second evaporator to the refrigerant within the second evaporator. A second blower is configured to blow air across the second evaporator to a second section of the cabin of the vehicle.

Abstract: A compressor includes a shell, first and second scroll members, a fitting assembly and a valve assembly. The first scroll member includes a first end plate having a first spiral wrap extending therefrom. The second scroll member includes a second end plate having a second spiral wrap extending therefrom and an injection passage formed in the second end plate. The second spiral wrap is meshingly engaged with the first spiral wrap to form compression pockets. The injection passage is in fluid communication with the compression pockets. The fitting assembly is in fluid communication with the injection passage. The valve assembly coupled to one of the second scroll member and the fitting assembly and movable between a closed position in which fluid communication between the compression pockets and the suction chamber is prevented and an open position in which fluid communication between the compression pockets and the suction chamber is allowed.

Abstract: A monitoring system is disclosed for a heating, ventilation, or air conditioning (HVAC) system of a residential or commercial building. The monitoring system includes an evaporator unit device including a first current sensor that measures current supplied to a circulator blower. The measured current from the first current sensor is used to diagnose a problem with the circulator blower. The monitoring system includes a first temperature sensor that measures refrigerant temperature between a condenser and an expansion valve. The monitoring system includes a second temperature sensor that measures refrigerant temperature between an evaporator and a compressor. The monitoring system includes a condenser unit device that communicates with the evaporator unit device. The condenser unit device includes a second current sensor that measures current supplied to the compressor. The evaporator unit device transmits sensor data to a remote monitoring service over a data network.

Abstract: A compressor may include a shell, a non-orbiting scroll, an orbiting scroll, and a discharge valve member. The shell may define a discharge chamber. The non-orbiting scroll may be disposed within the discharge chamber and includes a first end plate and a first spiral wrap extending from the first end plate. The orbiting scroll may be disposed within the discharge chamber and includes a second end plate and a second spiral wrap extending from the second end plate. The first and second spiral wraps mesh with each other to define fluid pockets therebetween. The second end plate includes a discharge passage extending therethrough. The discharge valve member may be attached to the second end plate and may be movable between an open position allowing fluid flow from the discharge passage to the discharge chamber and a closed position restricting fluid flow from the discharge passage to the discharge chamber.

Abstract: A system may include a compressor, a heat exchanger, an expansion device, and first and second working fluid flow paths. The compressor may include a compression mechanism and a motor. The heat exchanger may receive compressed working fluid from the compressor. The expansion device may be disposed downstream of the heat exchanger. The first working fluid flow path may fluidly connect the heat exchanger and the expansion device. The second working fluid flow path may be disposed downstream of the heat exchanger and may fluidly connect the heat exchanger with the compressor. The second working fluid flow path may provide compressed working fluid to the compression mechanism and to the motor.

Abstract: A system for monitoring health of refrigerated storage containers includes an instantaneous health module configured to determine instantaneous health values for a refrigerated storage container based on parameters measured by sensors of a refrigeration system of the refrigerated storage container during a trip of the refrigerated storage container. A statistics module is configured to, after completion of the trip of the refrigerated storage container, determine statistical values based on the instantaneous health values determined for the trip. A health module is configured to determine an overall health value for the refrigerated storage container at the completion of the trip based on the statistical values and to store the overall health value for the refrigerated storage container in memory in association with a unique identifier of the refrigerated storage container.
