  • Patent number: 9964325
    Abstract: An air conditioning system includes an outdoor unit, indoor units, a controller that controls the outdoor unit, and an equipment controller. The equipment controller stores a set lower limit value that is set to maintain a pressure difference between the high pressure and the low pressure in the outdoor unit at a predetermined value or greater. The lower limit value is set to be smaller as a minimum cooling capacity increases. The minimum cooling capacity is the minimum value of a cooling capacity of an indoor unit arrangement formed by the indoor units. When starting a cooling operation, the equipment controller determines whether or not to perform pressure difference control for limiting decreases in the pressure difference of the outdoor unit based on whether or not the temperature of water flowing into the outdoor unit is less than the set lower limit value.

  • Patent number: 9297374
    Abstract: Systems and methods relating to filtration in a pump are described. Even more particularly, systems and methods relate to optimizing operating routines of a pump based on the filter used with the pump. A system controlling a pump can receive filter information and process fluid information and select a priming routine for the filter based on the filter information and process fluid information. The pump can be operated according to the selected priming routine that includes a back pressure step to pressurize the filter from downstream.

  • Patent number: 9050957
    Abstract: The operation of an air compressor is controlled to control engine performance to thereby improve the performance of the vehicle. A compressor (4) driven by an engine (3) of a vehicle and supplying compressed air to loads (51-54) is controlled by an ECU (2). A loaded state and an unloaded state of the compressor (4) are switched between each other according to the requirements from the loads (51-54). When the vehicle requires braking force, the compressor (4) is set to the loaded state irrespective of the requirements from the loads (51-54).
