DYHGRG-14 Building Materials Thermal Resistance Heat Flow Meter Measurement Training Device
Release time：2024-06-12 19:00viewed：times
Technical parameters:
1. Input power: single-phase AC220V±10% 50Hz, power 3.0KW.
2. The temperature is measured by a temperature sensor (usually copper-constantan thermocouple or thermal resistor), and the heat flow is measured by a heat flow meter. The value measured by the heat flow meter is the thermoelectric potential, which is converted into heat flux density through the probe coefficient.
3. Cold box cold surface refrigeration system: QD91 compressor, filled with R12 refrigerant, 3.4m2 *r-cooled condenser with 40W motor .
4. Temperature measurement: 12-way temperature, range: -20℃―85℃; the measurement system is equipped with an intelligent temperature control instrument (PID temperature control, accuracy ±0.2℃), and a high-precision PID voltage regulation module circuit.
5. Dimensions: 2000×100×1600mm, the appearance is a st*nless steel movable bracket with double brake wheels.
Experimental purpose:
1. Master the measurement of thermal resistance and heat transfer coefficient of building
envelope structures. 2. It can be applied to scientific research of actual building envelope components <150mm.
