    摘要: The methods and instrumentations for measuring in real-time the two-phase mass flow rate and the enthalpy from the geothermal wells and large diameter pipelines can be used in memory and on-line to measure the mass flow rate and enthalpy when the two-phase pipeline is in operation or during testing. This measuring instrument consists of primary, secondary and multi-tapping components. The primary component can be a concentric orifice plate, a top eccentric orifice plate, a bottom eccentric orifice plate, a segmental orifice plate, Nozzle or Venturi tube. The secondary component is a transmitters-transducers. The multi tapping used are radius (ID and ID/2), flanges, corners and other arrangement or different combinations. On this device system, the data signal of upstream pressure, downstream and the pressure difference of the multi tapping is recorded and transmitted or recorded by the transmitters-transducers to the computer machine.

    摘要: The present disclosure relates to a performance forecasting method applied to an air conditioning equipment and a central server. The air conditioning equipment has a plurality of detecting elements so as to detect a plurality kinds of physical parameters and a performance parameter. The central server stores those parameters as a set of first parameters and a first performance value. When the central server receives other physical parameters and another performance parameter, it calculates the similarity between the other physical parameters and each set of the first parameters according to the law of cosines. The central server selects the set of the first parameters which have the similarity being greater than a selecting threshold, so as to calculating an expected performance value. Accordingly, the central server can forecast a performance decline degree by comparing the another performance parameter and the expected performance value.

    摘要: The aim of the invention is to provide a commercially usable and inexpensive device and method with which a sorption enthalpy can be measured in a simple manner. This is achieved by a device for calorimetrically measuring sorption processes, comprising a sorption cell for receiving a sample, the sorption cell having a volume for filling with a sorption gas, and comprising a reference cell likewise for filing with the sorption gas. A measurement gas volume is arranged around the sorption cell for receiving a reference gas, and the reference cell is surrounded by a reference gas volume, which is likewise provided for receiving the reference gas. A gas connection is provided between the sorption cell and the reference cell in order to conduct sorption gas into the sorption cell and the reference cell such that a sorption reaction occurs with the sample in the sorption cell. Furthermore, a device is provided for measuring pressure differences between the measurement gas volume and the reference gas volume in order to carry out a calorimetric measurement of the sorption process on the sample in the sorption cell on the basis of a volume change of the reference gas in the measurement gas volume.
