摘要： A refrigeration system includes a two-stage linear compressor having a first piston disposed in a first cylinder and a second piston disposed in a second cylinder. The linear compressor is operable in an economizer cycle wherein the first piston operates as a first stage of the economizer cycle and the second piston operates as a second stage of the economizer cycle. A controller is coupled to the linear compressor to control a volume flow ratio of the linear compressor. The controller stores a plurality of coefficients of performance for a range of particular operating conditions of the linear compressor and each coefficient of performance corresponds to a desired volume flow ratio and a desired secondary evaporating temperature. Based upon measured operating conditions of the linear compressor, the controller determines a highest coefficient of performance from the plurality of coefficients of performance and varies operation of at least one of the first and second pistons to achieve the desired volume flow ratio.

摘要： A commercial refrigeration system has a control system which distributes intelligence to increase granularity of the control and simplify wiring, assembly and installation. Compressors of the refrigeration system each have a bus compatible compressor safety and control module including a processor and sensors. All control and safety modules communicate over a single power and communications line with the controller, providing digital transmissions to the controller of measurements taken by the sensors. The information provided may include that the compressor is outside of a specific safety parameter, so that the controller knows not only that a safety parameter has been traversed, but exactly which one. The control and safety modules are capable of executing commands from the controller to cycle the compressors. The control and safety modules preferably contain sufficient intelligence to continue system operation upon failure of the controller. A compressor is also disclosed which has an intelligent control and safety module. The compressor also houses control and safety devices within a hermetically or semi-hermetically sealed shell. A condenser controller is also disclosed that is capable of communicating with the controller to affect intelligent control of one or more compressor fans.

摘要： A refrigeration system includes a dual-piston linear compressor including a first piston disposed in a first cylinder and a second piston opposed to the first piston and disposed in a second cylinder. The first piston divides the first cylinder into a first suction chamber and a first discharge chamber and the second piston divides the second cylinder into a second suction chamber and a second discharge chamber. The refrigeration system also includes a first gas flow path through the linear compressor, a second gas flow path through the linear compressor, and a controller operable to switch the linear compressor between an economizer cycle and a single stage cycle wherein in the economizer cycle flow of gas is along the first gas flow path and in the single stage cycle flow of gas is along the second gas flow path. At least one discharge control valve coupled to the controller and responsive to control signals from the controller is operable to direct gas from the first and second discharge chambers to the first gas flow path or the second gas flow path. At least one suction control valve coupled to the controller and responsive to control signals from the controller is operable to direct gas to the first and second suction chambers along the first gas flow path or the second gas flow path.

摘要： A combined heating, ventilation, air conditioning, and refrigeration (“HVACR”) system including an HVAC sub-system and a refrigeration sub-system. The HVAC sub-system is in communication with an open space of an indoor environment and includes a first condenser, a first evaporator, and a first compressor at least partially defining a first refrigerant circuit circulating a first refrigerant for selectively conditioning an airflow within the HVAC subsystem that conditions the open space. The refrigeration sub-system is in communication with an enclosed space within the indoor environment and includes a second condenser, a second evaporator, and a second compressor and at least partially defining a second refrigerant circuit circulating a second refrigerant for selectively conditioning the enclosed space. Heat from the second refrigerant is selectively transferred to the airflow within the second condenser to reheat the airflow prior to the airflow being discharged into the open space.
