The YBaCuO bulk is cooled down to different temperature and the levitation force is measured and analyzed using the HTS Maglev measurement system, the G-M refrigerator and the deep cool measurement system.
Based on a plan of boiler waste water remaining heat recovery with the lithium bromide absorption refrigerator in the thermal power plant, proposals, that should be paid attention to sufficient reutilization of not only its remaining heat but also its water resources during its design,are presented.
Energy efficiency standard of GB12021.2-2003 has its own limitation of developing super energy conservation refrigerator, which the grade of 1++(η≤40%) and 1+(40%<η≤50%)were added based on former standard from 1 to 5, and the other grades keep 10% disparity of energy index each other.
There are liquid crystal displays on the panel of the refrigerator, which shows the temperature between freezer and safe. It is possible to adjust and control the temperature between freezer and walk-in through the button ,reaching the temperature that user needs.
The auto control system controls the cold storage room and the freeze respectively. It realizes the control with the temperature sensor AD590,the pressure resistance gauge ZDY 1 and the control units,so it has the functions of the digital display and auto control. This new kind of refrigerator has no pollution.
All the 6 superconductive trasition points, i.e., those of Niobium, Lead, Indium, Aluminum, Zinc and Cadmium, in SRM767a device have been realized on a dilution refrigerator using an accurate mutual inductance bridge. The change of mutual inductance, AM and the transition width w are given. Tc values have been intercompared with the temperature values shown by 3 GRTs from Lake Shore cryotromics Inc.
It is necessory to be as the first consideration of selecting motor which used in a certain condition. In this article introduced the selection of different single-phase motors by domestic appliance feature as the refrigerator, washer. electrical razor, quartz watch, timer etc.
In this paper, the author formulates a principle of choosing the components concerned after analyzing the step-down rectifier circuits in condensers. It will be of some help to the design of power for such miniature equipment as refrigerator protector, warning device and remote control switch, and etc.
