The use of multi-channel, environmentally friendly and energy-saving (low noise) mechanical compression refrigeration system: all materials, parts, components, raw materials, etc. of this testing machine, whether domestic or imported, are made of environmentally friendly productsAccording to the mechanical compression refrigeration characteristics, the two-stage multi-channel main bypass system is adopted, the multi-channel main circuit and bypass can be selectively selected and enabled according to different working conditions, and the whole control is automatically realized by the intelligent control system according to the working conditions, which changes the traditional way of using a thermostat to control the heating capacity to offset the cooling capacity. So as to achieve the effect of energy saving, not only energy consumption accounts for only 80% of similar products. It also reduces the operating load of the refrigeration compressor, reduces the vibration and noise of the equipment, and improves the control accuracy. In order to better achieve the effect of energy saving, at the same time, the frequency conversion technology is used to make the refrigeration output of the refrigeration compressor adapt to the requirements of various different temperature change rates in the laboratory, and at the same time control the use of power loss to achieve the effect of energy saving. The whole structure and different places in the mechanical working process use sound absorption and sound reduction methods to reduce the noise of the whole equipment.
2.Self-developed multi-channel, multi-stage throttling system (refrigeration system): The refrigeration system of this testing machine is designed with different capillary main roads and bypasses according to different working conditions of the system, and the capillary throttling system is automatically controlled and automatically adjusted by the Zhitong control system according to the working conditions, so as to ensure that the flow rate is adjustable and the purpose of temperature change is achieved, and the temperature field changes uniformly and the temperature fluctuation is very small.
3.The wideband compression balance temperature control system is applied to realize the rapid temperature control through the fast convergence PID adaptive algorithm: the temperature adjustment chamber, the static pressure chamber and the forced air duct system of centrifugal fan blades are used to ensure the full exchange of cold and heat and evenly supply air through the top orifice plate to each space of the studio (experimental area) to achieve temperature uniformityIn order to achieve rapid convergence of temperature, our company has cooperated with South Korea Sanyuan Company to develop a special PID adaptive algorithm suitable for our company, which continuously corrects the control according to the temperature during the control process, so as to achieve the control purpose of fast sword retraction, small temperature overshoot and high stability. SUS304 (12mm thick) 8K mirror stainless steel plate, which has the advantages of acid resistance, corrosion resistance, and easy cleaning.
