19 Feb 2008TL;DR: In this paper, inlet air at an input of a compressor was used to generate compressed air at the compressor using the received inlet-air, and the compressed air from the compressor to a combustor, where the combustor produces combustion involving compressed air and fuel, and at least a portion of the exhaust gases were sent to the intake section via a recirculation line.
Abstract: Systems and methods may be provided for exhaust gas recirculation The systems and methods may include receiving, via an intake section, inlet air at an input of a compressor, generating compressed air at the compressor using the received inlet air, and providing the compressed air from the compressor to a combustor, where the combustor produces combustion involving the compressed air and fuel The systems and methods may also include receiving combustion products associated with the combustion at a turbine component, where the turbine component releases exhaust gases, and recirculating at least a portion of the exhaust gases to the intake section via a recirculation line, where the recirculated exhaust gases raise a temperature of the inlet air

17 May 1989TL;DR: In this article, a method for controlling a motor vehicle air conditioning system is described, which consists of a refrigeration circuit including a refrigerant compressor, a condenser, an evaporator and a throttle device arranged upstream of the evaporator.
Abstract: A method for controlling a motor vehicle air conditioning system is described. The motor vehicle air conditioning system comprises a refrigeration circuit including a refrigerant compressor, a condenser, an evaporator and a throttle device arranged upstream of the evaporator. The condenser is associated with a ventilating fan and the evaporator is associated with a blower. The compressor capacity, the condenser capacity and the evaporator capacity are directly or indirectly sensed by sensor means and supplied as electrical variables to an electronic control circuit which logically combines these input signals and generates output signals in dependence on at least two of these capacity values and including further parameters. The control circuit acts on electrically controllable acturators for influencing the compressor capacity, the condenser capacity and/or the evaporator capacity.

11 Apr 1997TL;DR: A surge detection system for use in a fluid system having a load driven by a centrifugal compressor (12), the compressor being driven by an electric motor (20) was proposed in this article.
Abstract: A surge detection system for use in a fluid system having a load driven by a centrifugal compressor (12), the compressor (12) being driven by an electric motor (20). The surge detection system comprises a means (38, 40) for sensing a differential pressure developed across the compressor (12) and a means (42) for sensing a current representing input power to the motor (20). The surge detection system further comprises a first computing means responsive to the differential pressure developed across the compressor (12) for indicating when a valid surge is occurring in the compressor (12), and a second computing means responsive to the variable speed drive current for indicating when a valid surge is occurring in the compressor (12).
