The corresponding method of controlling the temperature of the working fluid discharged by the fluid compressor is also disclosed.

    Abstract: A control system for a variable displacement pump driven by a drive source for driving a vehicle is provided. The variable displacement pump pressurizes hydraulic oil, and is switchable between a full capacity operation in which a discharge flow rate is maximized and a partial capacity operation in which the discharge flow rate is lower than that in the full capacity operation. It is determined whether an operation for starting the drive source has been performed. A rotational speed of the drive source and a temperature of the hydraulic oil are detected. When the rotational speed of the drive source is equal to or higher than a predetermined rotational speed and the hydraulic oil temperature is equal to or lower than a predetermined temperature, immediately after the operation for starting the drive source is performed, the partial capacity operation of the variable displacement pump is performed. This control suppresses generation of untoward noises caused by the operation of the variable displacement pump when starting to drive the vehicle.

    Abstract: Disclosed is a method for controlling operation of a compressor, according to which the compressor is shut off by a control device in order to prevent thermal damages when an estimated temperature value Ts calculated by said control device exceeds an upper threshold value Tmax while the compressor remains on or is allowed to be turned on when there is a need for compression and a lower threshold value Tmin is not reached. In order to be able to more accurately estimate the estimated temperature and increase the thermal availability of the compressor, the estimated temperature value Ts is indirectly and cyclically determined by means of a mathematical-physical model that characterizes the cooling and heating properties of the compressor.

    Abstract: An electronic control system (52) and method for controlling and preventing damage to a stand alone or network of oil free, two stage compressor packages (50). To prevent the occurrence of a high temperature condition and subsequent seizure of the compressor, pressure (76, 72) and temperature (60, 62, 58) sensors are disposed at strategic locations in the compressor package. The electronic control system (52) detects and predicts failure based on pressure and temperature differentials and shuts the compressors (54, 56) down before actual failure. The electronic control system (52) records the shutdown parameters in non volatile memory and displays a reason for shutdown. A plurality of electronic control systems (52) can be connected in a peer-to-peer network to coordinate control of a plurality of compressors connected to the same air distribution system.
