  • Patent number: 10563893
    Abstract: Apparatuses, methods, and systems for adjusting scale(s) of a refrigerant recovery system (RRS) are described. The RRS can determine pressure and weight measurements of content within a refrigerant storage tank. The RRS can determine weight measurements of content within oil storage containers. The RRS can compare the pressure and weight measurements to thresholds to determine whether the scale(s) require adjusting, whether the RRS should be locked to prevent further use of the RRS until after servicing of the RRS, or whether additional functions of an operating state of the RRS should be performed. The RRS can comprise a processor to automatically adjust the scales, determine the pressure and weight measurements, and compare pressure and weight measurements to the thresholds. Locking the RRS can prevent the RRS from recovering refrigerant from a cooling system, such as an air conditioning system in a vehicle.

A control device detects a hot water outflow temperature being a temperature of a fluid heated by a heat pump device, and a return temperature being a temperature of the fluid before being heated by the heat pump device, and checks whether or not a temperature difference between the detected hot water outflow temperature and the detected return temperature is smaller than a predetermined first value. If the control device judges that the temperature difference is smaller than the first value, it displays insufficiency of the heat dissipation amount of a heat exchange device, on a display of a remote controller.

    Abstract: A system includes a control module and a monitor module. The control module selectively operates a component of the system in an ON state. The system receives power from an electrical grid. The monitor module selectively detects a fault event of the electrical grid in response to (i) an amount of current drawn by the component or (ii) a voltage of power received by the component. In response to detecting the fault event, the control module switches the component from the ON state to a second state, determines a first delay period according to a random process, identifies an apparent conclusion of the fault event, and in response to the apparent conclusion of the fault, waits for the first delay period before switching the component back to the ON state.

  • Patent number: 8978398
    Abstract: An expansion valve assembly includes a housing that defines a passage through which a fluid flows. The assembly also includes a diaphragm that deflects according to a characteristic of the fluid and valve member that is operably coupled to the diaphragm to move within the passage between a first position and a second position due to deflection of the diaphragm to regulate flow of the fluid through the passage. A stroke is defined by a distance between the first and second positions of the valve member. Moreover, the assembly includes a stroke measuring device having a first member and a second member. The first member is operably coupled to the valve member to move relative to the second member due to movement of the valve member. The stroke measuring device is operable to detect the amount of relative movement of the first and second members to detect the stroke.

    Abstract: In order to improve a refrigerant compressor comprising a drive motor and a compressor unit which compresses a refrigerant entering through a suction inlet and allows it to exit through a pressure outlet in such a way that it works as reliably as possible, it is proposed that the refrigerant compressor comprise a compressor monitoring system which is integrated into a compressor control system and which determines a compressor condition by means of a first condition value that corresponds to a first saturation temperature in the suction inlet and a second condition value that corresponds to a second saturation temperature in the pressure outlet, and which compares the compressor condition with permissible compressor conditions lying in a given deployment field of a deployment diagram and initiates a process of switching-off the refrigerant compressor if the compressor condition departs from the deployment field.

  • Patent number: 8850838
    Abstract: 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.
