Screw chiller control system new achievements

The hot summer has arrived and the refrigeration industry is springing up. The fierce development of the screw compressor market has promoted a new opportunity for development in the upstream and downstream industrial chain products. In the field of microcomputer controllers, the Suzhou Suzhou New Asia Technology Co., Ltd. has introduced a special screw machine control module that is more targeted and professional. For different screw compressors, the traditional control mode is completely out of hardware and software, and different types of independent module programs are easily implemented so that most of the screw machines in the refrigeration industry on the market can be matched, including the mainstream Han. Bell, Fusheng, Bitzer, LaiFuKang, FuShiHao, and other domestic brands of screw compressor control operation logic, at the same time with the compressor group self-diagnosis function, making the control and debugging a series of sales and after-sales service more Safe, simple and effective. 2015 China Cold Expo market industry entered Suzhou New Asia Technology Co., Ltd. to share the innovation results of the new Asia PLC2.0 series products.

PLC refers to the programmable logic controller. New Asia's latest PLC2.0 series has been upgraded on the basis of original products: R&D for the refrigeration industry, dedicated to refrigeration, and better understanding of the performance of refrigeration units and equipment; no programming and verification required , The mature control logic is implanted inside and the professional degree is improved; the touch screen can flexibly switch different parallel connection group screens and multiple cold storage screens, and the setting and viewing are more convenient; the humanized operation design supports the remote modification of the software. Wen Jianzhong, general manager of Suzhou New Asia Technology Co., Ltd., told reporters of the Refrigeration Express that the screw, cold water, parallel, and barrel pump currently developed by Suzhou Xinya, the flood control unit and the traditional control mainly broke through the following major technical bottlenecks:

1. High-low temperature startup mode of non-isothermal storage, measurement and measurement of COP energy efficiency;

2, anti-lock liquid compressor compressor system MOP lock technology;

3. The defrosting system and the refrigeration system can be operated at the same time to achieve a non-destructive defrosting and zero-electric-power loss;

4. Compatible with the energy operating modes of the compressors of the six major brands in the world, supporting a variety of screw machine models, solving general and standard problems, and maximizing the purchase cost;

5. Automatic calibration of barrel pump and flooded inner liquid level, failure of automatic pump change operation, solving the multi-point oil return control technology of fluorine barrel, and allowing the action of liquid splashing in fluorine barrel to cause malfunction control technology.

6. Solve the fault self-diagnosis function of the unit.

Xinya has a strong market sensitivity, can quickly respond to new market development trends, use innovative innovations to arm its products, and put R&D into practice. At the same time, a strong sales network and mature sales channels are one of the key factors for the rapid development of Xinya products. However, with the "Internet Plus" and the growing trend of localization of refrigeration products, New Asia is paying close attention to the changes in the new refrigeration market. Li Yiqiang said that the Internet is for the refrigeration sales market to cut off the intermediate links and reach the terminal. This year, the wholesalers nationwide have shown a downward trend, and the future “provincial agents” will also be gradually disintegrated. Regarding the general trend of localization development of refrigeration units proposed by Wen, Li Yiqiang believes that although the localization trend of library products has become a fact, due to the high technical requirements of the unit, it is influenced by factors such as the brand, product level and after-sales service of the unit, 5 It is difficult to achieve local development during the year. More current situation is that agents sell accessories while also integrating parts into one product for sale. If this trend is regarded as a localization development, it is currently not mature as a whole. Truth is: How the market will go in the future, and a hundred schools of thought will have a head start. There is a certain degree of advancement and retreat, and users say good is good.
