The equipment fully meets the detection method and detection accuracy requirements of relevant national standards, and has the function of automatic fault-free operation, self-diagnosis, monitoring, automatic test function of calibration experiment, and the function of storing experimental records and printing original data in the whole process.
2. test items:
It is used for the detection of heat transfer coefficient of building wall and thermal insulation board.
3. basis standard:
GB/T13475 "Determination of steady-state heat transfer properties of building components-Calibration and protective hot box method"
4. technical parameters:
(1) Temperature control range of protective box: 15~50 ℃, continuously adjustable, control accuracy: ± 0.1 ℃;
(2) Cold box temperature control range:-10 ~-20 ℃, control accuracy: ± 0.2 ℃;
(3) Measurement accuracy of the instrument: ≤ ± 5%, repeatability: ≤ ± 1%;
(4) Rated power: power: AC380V, three-phase five-wire system: 3kVA
(5) Specimen specification: 1212 type: maximum measurable specimen size: 1630mm × 1630mm × 300mm;
1515 type: maximum test piece size: 1920mm × 1920mm × 450mm.
(6) Overall dimension: 1212 type: 2560mm × 2450mm × 2150mm (length × width × height);
Minimum floor area: 3500mm x 5000mm x 3200mm (length x width x height).
1515 type: 2600mm × 2600mm × 2400mm (length × width × height);
Minimum footprint: 4000mm x 5500mm x 3500mm (length x width x height).
5. test device structure:
(1) The host adopts polyurethane insulation board insulation design, which has better insulation effect;
(2) using the United States DALLAS digital temperature sensor, to achieve continuous temperature control, no interval;
(3) The equipment is placed on the I-shaped rail to make the opening and closing of the box more convenient and labor-saving;
(4) The sample frame shall be designed in the shape of "∏" gate. It not only reduces the number of specimen frames, saves a lot of procurement costs and test space, but also facilitates the air drying of specimens and the clamping of specimens.
