Technical parameters:
1. Input power supply: single-phase AC220V±10% 50Hz, power 5.0KW.
2. The experimental *r duct is made of transparent organic glass and is divided into an *r outlet section, an experimental section (the experimental section can be disassembled and replaced), a test section, etc., which are connected by flange nuts.
3. Centrifugal fan parameters: *r volume 1000 m3/h, wind pressure 1000 Pa, power 370W.
4. Rotating cylindrical specimen, experimental tube specification: Φ32 × 250mm, made of copper tube. An electric heater with a power of 300W is installed in the tube as a heat source, and four thermocouples are embedded in the tube wall to measure the wall temperature.
5. Copper flat plate specimen, specifications: δ=4 mm, length 250mm, width 150mm, flat electric heater power: ≤500W.
6. The gas-water heat exchanger test piece uses water to heat the gas. The hot water flows through the small heat exchanger to cool down, and the *r heats up through the small heat exchanger. Hot water is heated by an electric heater. The heat exchanger area is 1.0m2, the water flow rate is 16~160L/h, and the liquid heating power is 2.0KW.
7. Tube tube external heat release test piece: fin type (aluminum rolled tube) heat pipe heat exchanger, size Φ20 × 250mm, material red copper tube. Arrange in a cross row or in a row.
8. Pitot tube flowmeter is equipped with a differential pressure sensor : range 0-1000Pa, accuracy 0.5.
9. Temperature measurement: The measurement system is equipped with an intelligent temperature control instrument (PID temperature control, accuracy ±0.2°C) and a high-precision PID voltage regulation module circuit.
10. The universal signal input inspection instrument is combined with a high-precision digital display meter to display all experimental measurement parameters such as temperature, resistance, flow rate, etc., and the manual damper adjusts the *r volume.
11. Dimensions: 2000×500×1700mm. The shape is a st*nless steel movable bracket with double brake wheels.
12. 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.
