Title: A method for controlling an expansion device
Inventor: WURTZ ALBRECHT
IPC: F25B49/02
Filed: 2017-04-26
Abstract: A method for controlling an opening degree of an expansion device (4) arranged in a vapour compression system (1) is disclosed. An actual pinch being the difference between temperature of a secondary fluid flow (6) across the evaporator (5), at a position after the secondary fluid flow (6) has passed the evaporator (5), and an evaporating temperature of refrigerant passing through the evaporator (5), is obtained. It is determined whether or not internal instability is present in the vapour compression system (1), and a setpoint pinch value is decreased in the case that internal instability is not present in the vapour compression system (1) and increased in the case that internal instability is present in the vapour compression system (1). An opening degree of an expansion device (4) is controlled in order to obtain an actual pinch which is substantially equal to the setpoint pinch value.

Patent SE-503458-C2 (SE)
Inventor: BRUENING PAUL
IPC: B04B11/00
Filed: 1987-08-07
Abstract: The intake space of a centrifuge drum is divided into a vestibule with ribs and an intake chamber without ribs. The vestibule communicates with the intake chamber through an annular gap between the outside diameter of a disk secured to an intake pipe and the inside diameter of the intake space. The intake chamber communicates with a set of disks through channels. The diameter DK of the intake chamber at the level of the channels is longer than the diameter DF that must be maintained at the upper surface of the centrifugate in a skimming chamber during operation. Since the incoming centrifugate does not rotate in the intake chamber and since no rotational pressure is accordingly generated, the intake pressure in the intake pipe is transmitted when the intake chamber is full to the centrifugate in the intake chamber, until the requisite level of centrifugate in the skimming chamber is attained. The pressure that is transmitted to the annular gap is compensated for by the rotational pressure of the centrifugate in the vestibule, allowing absolutely smooth distribution of the centrifugate when the intake chamber is full throughout the whole operational range of the drum.
