摘要： A method for balancing a pump load of a plurality of pumping units during a pumping operation comprising determining a first balance pump load based on a set of weighted factors. The method determines a second balanced pump load after receiving an indication of reduced pumping performance from a first pumping unit. The method excludes the first pumping unit from the second balanced pump load while maintaining the flowrate of the first balanced pump load. The method determines a transition pump load to transition from the first pump load to the second pump load as the first pumping unit ramps down.

摘要： A compressed air production facility that reduces an extension cost without stopping an operating air compressor in a case of increasing the number of air compressors to cope with an increase in demands for compressed air is provided. A compressed air system supplies compressed air to compressed air consuming devices connected to a compressed air distributions line, the compressed air system including a plurality of air compressor units connected to the compressed air distributions line via respective air tanks. Each of the air compressor units includes: an air compressor main body; an adjustor of pressure setpoint that adjusts a pressure setpoint of an air tank to which the air compressor unit including the adjustor of pressure setpoint is connected; and a controller of air compressor that operates a rotational frequency of the air compressor main body on the basis of the pressure setpoint adjusted by the adjustor of pressure setpoint and a pressure of the air tank. The adjustor of pressure setpoint adjusts the pressure setpoint on the basis of a control variable indicating the rotational frequency of the air compressor main body or the pressure of the air tank.

摘要： A bi-directional pump system that can be configured for a plurality of operating modes. The bi-directional pump system includes a plurality of bi-directional pumps each having their own valving system that are connected to a common high pressure manifold, a low pressure manifold and a suction manifold. Via the respective valve systems, each pump can be configured into: (1) a single-acting pumping mode; (2) a double-acting pumping mode; (3) an inactive free motion mode; and (4) an inactive rigid mode. One exemplary application of the bi-directional pump system is on an articulated wave energy conversion system that consists of three floating barges: a front barge, a center barge and a rear barge where the front barge and center barge are hingedly connected as are the center barge and the rear barge. A first set of the bi-directional pumps span the first hinge connection and the second set of bi-directional pumps span the second hinge connection. The bi-directional pump system intakes sea water and, using wave energy, outputs a high pressure flow of sea water for water desalination and/or for driving electrical generators.

摘要： A caloric heat pump system includes a pair of caps mounted to a regenerator housing. Each cap of the pair of caps defines an inlet and an outlet. The outlet of each cap of the pair of caps is positioned at a chamber of the regenerator housing. The inlet and outlet of each cap of the pair of caps defines an area in a respective plane that is perpendicular to the longitudinal direction. The area of the inlet of each cap of the pair of caps is less than the area of the outlet of each cap of the pair of caps.

摘要： A method for controlling and/or monitoring a compressor system is provided. The compressor system includes one or more compressors and one or more peripheral devices. The compressors and peripheral devices are arranged or connected in a predetermined configuration. The compressor system is controlled and/or monitored by a control/monitoring unit. The method involves creating one or more derived models on the basis of one or more initial models of the compressor system that are based on a P&I diagram. The derived models take into account the operative interrelationships among the individual compressors and peripheral devices, and optionally also dynamic processes. The one or more derived models form the basis for subsequent control, monitoring, diagnosis or evaluation routines.

摘要： A fluid valve is described to help reduce oil sump pressures of a variable speed compressor and a fixed speed compressor working in parallel in a HVAC system. The fluid valve can be a ball valve. Openings of a variable flow through structure of the ball can be configured to elongate along an equator the ball. When the ball rotates along a rotation axis, a size of a variable fluid path formed between the openings can be varied, resulting in a variable pressure drop across the ball. In operation, when the variable speed compressor is operated at different operation speeds, the ball can be rotated to different positions relative to the rotation axis, which may help reduce the pressure differential between the sumps of the variable speed compressor and the fixed speed compressor.

摘要： A valve device controls the air intake for a compressor of a vehicle. The valve device includes a valve housing having a first compressed air inlet for connecting to an ambient air infeed, a second compressed air inlet for connecting to a charge air infeed, through which pre-compressed air can be fed, and a compressed air outlet for connecting to the compressor. The valve device includes a first switched state in which the compressed air outlet is fluidically connected to the first compressed air inlet, and a second switched state in which the compressed air outlet is fluidically connected to the second compressed air inlet. The valve device includes a switching device capable of switching the valve device between the first switched and the second switched state.
