Features: In the general adiabatic temperature rise design method, in order to keep the ambient temperature consistent with the specimen temperature, in addition to complying with the national standard tracking accuracy ≤±0.05°C, the deviation value corresponding to the specimen temperature should be calibrated to ensure the concrete specimen. The authenticity of the adiabatic temperature rise temperature, even if the above measures are adopted, because the randomness of the system error cannot always correspond to the deviation value one-to-one, and the tracking accuracy is also random, so the concrete specimen is more or less released to the environment. heat or absorbed heat, so that the temperature curve of the concrete specimen loses a certain authenticity. For this reason, our company has designed a set of software and hardware control system on the basis of the above two measures, so that under the same tracking accuracy and deviation value, the heat released or absorbed by the test piece to the environment is reduced by half. Technical parameter: 1. Dimensions: 1050×1875×1750mm 2. Studio size: 800×800×1100mm 3. Working temperature: 5-85℃ 4. Tracking accuracy: ≤±0.05℃, the temperature change of 50L water in 72 hours is ≤±0.05℃ Note: Control instrument: It is a new generation of high-resolution, high-precision, high-performance instrument with completely free input, ten groups of expert PID parameters, more advanced regional PID algorithm, high-resolution thousand degrees with decimal point, platinum resistance 0.000-30.000 , 1/14000 to adjust the resolution (this product uses platinum resistance Pt100, temperature range 0-100 ℃, two decimal places). 5. Refrigeration system: The refrigerator is selected from French "Taikang", with a double-tank cascade structure, with double water pumps and variable frequency speed regulation, which can quickly provide cooling capacity in the stabilization stage; In the high temperature stage, the flow rate of the water pump is reduced to reduce the heating power (heating control adopts the thermal "balance method") to save energy consumption. 6. Deviation value: The computer is automatically given according to the collected ambient temperature and specimen temperature. 7. Heating power: 2KW 8. Cooling power: 1.1KW
