Abstract:
Coupling device to transferring a flow of fluids or substances, which device comprises a first coupling element (1) and a second coupling element (11). The first coupling element (1) comprises fluid channels with displacing elements (4) and first sealing elements (7) positioned by spring force from the biasing members (6) to seal the fluid openings in the displacing elements(4) when the coupling device is disconnected by the two coupling elements separated. The second coupling element (11) comprises fluid channels with valve bodies (15) positioned by spring force from second biasing members (16) to close the fluid openings and second sealing elements (17) to seal the second bores(13) in the second coupling element (11) when the coupling device is disconnected. When the two coupling elements are pushed together and guided by guiding elements (30) the fluidic flows are connected between inlets (14) and outlets (9). The sealing elements (7, 17) ensure tightness.
Abstract:
The invention provides a method of controlling a release of thermal energy in a building. The method comprises steps of defining a control criterion for the building, defining a set of climate variables which influence the release of thermal energy in the building, and defining for each climate variable, a climate signification index which defines the importance of that climate variable for the release of thermal energy in the building. Furthermore, the method comprises a step of receiving a set of predicted future climate variables, and subsequently a step of combining the climate signification indices and the predicted future climate variables to provide control instructions for release of an amount of thermal energy in the building to satisfy the control criterion. The invention further provides a comfort control system.
Abstract:
This invention relates to a unique occupancy-based electronic control of energy consuming devices, such as household devices like, but not limited to, thermostats, HVAC systems, radiators in general, or any device consuming energy even though no users of the device are present. The control and/or regulation is based on the distance and velocity of the inhabitants relative to the household. An additional feature is a peak load management system ensuring to store energy in energy reservoirs prior to load peaks on the electricity distribution network, using this energy during the load peaks.
Abstract:
A magnetic actuator (1 ) comprising a stationary part (3), a movable part (4) and a coil (10) arranged circumferentially relatively to the movable part (4) in such a manner that the movable part (4) is moved relatively to the stationary part (3) in response to a magnetic field induced when an electrical current runs in the coil (10). The stationary part (3) and the movable part (4) are shaped in such a manner that one is provided with a protruding part (5) and the other is provided with a recess (6) adapted to receive the protruding part (5). Thereby the minimum distance between the stationary part (3) and the movable part (4) are kept relatively low, and it is thereby possible to obtain a large pulling force without increasing manufacturing costs. The actuator (1 ) further comprises a shading ring (7) providing a magnetic field having a phase which is different from the phase of the field induced by the coil (10). This prevents the movable part (4) from repeatedly hitting the stationary part (3) and makes the actuator (1 ) suitable for use in AC as well as DC applications. The actuator (1 ) is suitable for use in a magnetic valve (9).

Abstract:
A flow system, preferably a micro fluidic system, having a base part (4) with at least one flow path formed therein and a lid part (5) being attached to the base part (4) in such a manner that it covers the flow path(s). The flow path(s) comprise(s) a flow restrictor (1) and a flow channel comprising an inlet section positioned immediately upstream relatively to the flow restrictor (1). At least the inlet section of the flow channel has a cross section defining at least two distinct depths of the flow channel. This may be achieved by defining a centre section (3) and at least one peripheral section (2), the centre section (3) having a depth and a width which are substantially larger than the depth(s) and width(s) of the peripheral section(s) (2). If air bubbles are formed in the system this design of the inlet section will allow a flow of liquid to enter the shallower parts of the flow channel, while the air bubbles are confined to the deeper parts of the flow channel. Thereby air bubbles are prevented from entering the flow restrictor (1), thereby reducing the risk of air bubbles blocking the flow path through the flow restrictor (1). Simultaneously liquid is allowed to flow into the flow restrictor (1) substantially unaffected by the air bubble. Accordingly the flow system operates in a very reliable manner.
Abstract:
The invention provides a membrane pump e.g. for a mini or micro channel system. The pump has a fluid conduit from an inlet through a displacement chamber with a variable volume to an outlet. The conduit is formed in a first component, and a displacement actuation structure adapted to affect volume change of the displacement chamber as well as an upstream and a downstream valve structure adapted force the fluid in one direction are separated from the fluid and detachably attachable to an outer surface of a first component which forms the fluid conduit. The invention therefore facilitate a simple and reliable pump of which some components can be reused while one component which is contaminated by the pumped fluid, can be disposed of.
