distance also makes it difficult to design a magnet-sensor combination that meets an arbitrary specification for mechanical turn-on and turn-off points. The nonlinear character of the magnetic field vs. This means that the closer you get to the magnet, the more sensitive the field measurement will be as a function of position. distance is greater near the magnet than further away. This is because the gradient of field vs. While it is possible to get consistent mechanical operate points by using a sensor with a high B OP switch point, so that it turns ON close to the face of the magnet, release points tend to be less consistent, especially for parts with large hysteresis values (B H). Determining mechanical operate and release point from B OP, B RP and a flux map. The optical simulation illustrates that the 100% acceptance angle of ACPC approached ±45 degrees, which means it could be set stationary in a year.įigure 6-2. studied the concentration performance of the ACPC shown in Fig. 2.91B.
Results showed that the new ACPC had lower mean daily efficiency and contributes to better water heat preservation during the night compared with the system with a symmetric CPC reflector. A comparison between the new ACPC and symmetric CPC was investigated.
The new ACPC has only one receiver, shown in Fig. 2.91B. Tripanagnostopoulos also designed an integrated collector storage solar system (ICS) with a parabolic-involute compound ACPC. This kind of ACPC has a large receiving area because it has two receivers thus it has a low geometrical concentration ratio and can be used only for low-temperature fields. designed and tested a solar collector consist of two separate absorbers horizontally incorporated into a stationary ACPC mirror, shown in Fig. 2.91A.
