Operation manual for the Oubair heat‑transfer training device, covering system overview, controls, data calculations and simulation screens.
The manual introduces the heat‑transfer training device, its purpose, basic heat‑transfer principles and the various heat exchangers (shell‑and‑tube, serpentine, tube‑bundle and spiral plate). It also lists the instrumentation such as flow meters, pressure gauges and temperature sensors used in the system.
Detailed operating procedures are provided, including normal start‑up, steam‑pressure control, air‑flow regulation, and temperature control for each heat exchanger. The document contains data‑calculation examples, results tables and screenshots of the simulation interface. This manual is written in Chinese.
| Shell‑and‑tube heat exchanger I dimensions | L=1.5 m, d=0.05 m, area = 0.24 m², pressure drop = 0.25 kPa |
|---|---|
| Shell‑and‑tube heat exchanger II dimensions | L=1.5 m, d=0.05 m, area = 0.24 m², pressure drop = 0.25 kPa |
| Fan I model and power | YS‑7112, 550 W |
The steam‑pressure control range can be set between 0.05 MPa and 0.1 MPa on the AI501 digital display instrument.
Air flow is regulated by setting a pressure‑difference value on the AI519 instrument, which sends a signal to the fan frequency converter; the fan speed changes, adjusting the flow measured by the differential pressure sensor.
