1、 Product Introduction:

The icing freezing rain laboratory is also called the icing freezing rain laboratory, which is mainly used to determine the suitability of electronic products, components, materials, etc. for use and storage under the conditions of High humidity, low humidity, icing, water dripping, spray, constant damp heat, temperature cycling change, and damp heat that generates condensation on the humidity surface< Our laboratory adopts a relatively reasonable structure and stable and reliable control method, making it aesthetically pleasing, easy to operate, safe, and with high humidity control accuracy. It is an ideal equipment for conducting low humidity tests, constant temperature and humidity tests, and alternating humidity tests< 2. Product Advantages and Technical Features:

1.2.1、 Utilize a multi-channel, environmentally friendly and energy-saving (low-noise) mechanical compression refrigeration system< All materials, parts, components, raw materials, etc. of the equipment, whether domestic or imported, are made of environmentally friendly products; Based on the characteristics of mechanical compression refrigeration, a two-stage multi-channel main and bypass system is adopted. The multi-channel main and bypass can be adaptively selected and activated according to different working conditions. The entire control is automatically implemented by an intelligent control system according to the working conditions, changing the traditional way of using a temperature controller to control the heater to offset the cooling capacity to control the cooling capacity. So as to achieve energy-saving effect, not only does the energy consumption account for only 80% of similar products. It also reduces the operating load of the refrigeration compressor, reduces equipment vibration and noise, and improves control accuracy. To achieve better energy-saving effects, frequency conversion technology is adopted to adapt the refrigeration output of the refrigeration compressor to various temperature change rate requirements in the laboratory, while controlling the power loss during use to achieve energy-saving effects. Use sound-absorbing and silencing methods in different parts of the entire structure and mechanical working process to reduce the overall noise of the equipment< br/> 1.2.2、 Independently developed multi-channel and multi-stage throttling system (refrigeration system)< The refrigeration system of this equipment is designed with different capillary main and bypass paths based on different operating conditions. The capillary throttling system is automatically controlled and adjusted by the intelligent communication control system according to the operating conditions, ensuring that the flow rate is adjustable and achieving the purpose of temperature change. Moreover, the temperature field changes uniformly and the temperature fluctuation is minimal.

1.2.3、 The broadband compression balance temperature control system is applied to achieve rapid temperature control through a fast convergence PID adaptive algorithm< Using a temperature mixing chamber, a static pressure chamber, and a forced air duct system with centrifugal blades to ensure sufficient exchange of cold and heat and uniform air supply through the top orifice plate to each space in the working room (experimental area), achieving temperature uniformity; To achieve rapid temperature convergence, our company has collaborated with Sanyuan Corporation in South Korea to develop a dedicated PID adaptive algorithm suitable for our company. This control method continuously adjusts the control according to the temperature situation during the control process, achieving the control objectives of fast sword retraction, small temperature overshoot, and high stability.

1.2.4、 Realize remote visual control< The device is equipped with a human-machine management interface and a touch mode automation control system to achieve automatic control; Simultaneously, connect to remote computers through RS485 communication interface to achieve network management and remote monitoring. The entire system is controlled and managed through a graphical interface, which is simple and fast, with automatic fault prompts. The graphical prompts are energy-saving and provide solutions to guide users in quickly troubleshooting< III. Laboratory Performance Indicators and System Composition of Ice and Freezing Rain.
