Device function:
Observe the flow state of fluid water in the rising film evaporator (bubble flow, bullet flow, stirring flow and annular flow).
Measure the convective heat transfer coefficient and steam dryness under different flow patterns.
Design parameters:
Heat transfer coefficient: 1000-5000 (w/m.2.oC). Liquid flow: 4~40L/h, normal pressure operation.
Utilities:
Water: The unit comes with a st*nless steel water tank and is connected to tap water. During the experiment, it enters the test pipeline through the centrifugal pump and is recycled.
Electricity: voltage AC220V, power 2.5KW, standard single-phase three-wire system. Each laboratory needs to be equipped with 1~2 grounding points (safety ground and signal ground).
Experimental materials: clean tap water, external equipment: none.

10. Raw material box, volume 80L, made of 304 st*nless steel.
11. 6 thermocouples for body temperature, wall temperature and steam temperature.
12. Yudian AI702M multi-channel digital temperature display instrument. Yudian AI518 temperature controller (with manual function).
13. Chint Electric: contactors, switches, leakage protection *r switches.
14. Instrument cabinet: Measurement and control and electrical equipment are on the experimental rack.
15. Overall dimensions: 1500×550×1800mm (length×width×height), movable design, with brake wheels, high-quality aluminum alloy profile frame, no welding points, easy installation and disassembly, horizontally adjustable support casters.
16. Engineering signs: including equipment tags, pipeline flow direction arrows and logos, valve tags and other engineering equipment concepts, including safety warning signs, so that students can be in a safe experimental operating environment and learn to recognize engineering pipeline signs. knowledge and cultivate students’ engineering concepts.
17. Virtual simulation software for electrical installation of building buildings and smart buildings. Based on unity3d design, users can choose different interactive interface sizes according to computer configuration, and can choose from six image quality levels. The model in the software can be rotated 360°, enlarged, reduced, and translated. There are assistant prompts during the use of the software, and the content is as follows: A. Wet alarm system 1.
