In March 2024, the customer in Anhui Province signed a 30Nm3/h 93% oxygen generator contract with Zhongsu Hengda. The production time given by the customer is short, only 15 days. And the customer has put forward high requirements for the quality and appearance of the equipment.

Through the cooperation of the production department, we delivered the oxygen system to the customer on time with quality and quantity in late March.

After our after-sales engineers to the site installation, the set of combustion aid oxygen generator has been normally put into use.

With the rise of China's independent brands, joint venture cars are no longer the primary choice for people to buy cars, and domestic cars are more and more favored by consumers. Take Ruicheng CC launched by Chang'an Automobile for example. With intelligent operation, safe performance and ultra-high appearance, it has won many praise.


Choose a car and look at your appearance first. The new family design of this car is really eye-catching, simple and beautiful. The "butterfly wing" front grille brings a very tension visual impact. The smooth skirt line and double waist line, combined with the sliding back shape, are very dynamic. The fashionable embracing cabin design is adopted for the interior, and a large number of soft bag materials and manual stitches have raised the sense of grade. The eight way electric adjustment of the driver's seat and the four-way electric adjustment of the co driver's seat, as well as the welcome and comity function, will automatically back 70mm when the door is turned off and opened, making it more convenient to get off; After the vehicle is powered on, the seat will automatically move forward 70mm to the previously set position. Of course, this function can also be turned on and off by itself.
In terms of safety performance, Ruicheng CC includes the instrument panel and central control screen composed of double 10.25-inch high-definition large screens, which interact with each other. You can cut the screen between the instrument panel and central control screen by swiping the screen left and right with three fingers. Equipped with real scene digital reconstruction technology, ACC full speed adaptive cruise, LDW lane departure warning, PAB warning auxiliary braking system, TSR speed limit identification, radar detection and other information can be directly fed back to the instrument panel. At the same time, it adopts up to 56% of the vehicle height strength steel application, with high-strength energy absorbing body structure, equipped with 6 airbags, pre tightening force limiting seat belts, direct TPMS intelligent tire pressure monitoring, integrated ESC electronic stability control system, etc.
In addition, Ruicheng CC is also equipped with forest air forest air purification system, which can deeply purify PM2.5 and harmful substances, and reduce the content of PM2.5 in the car to high-quality air standard in 3 minutes; The low-temperature plasma generator can filter more than 80% of harmful substances such as sulfur dioxide, nitrogen dioxide and benzene, and release negative oxygen ions to achieve forest air quality. And unlock the functions of automatic ventilation and automatic drying of evaporator to ensure a good air environment in the vehicle.
In April, Chang'an released the design concept of "dynamic life", saying that it would change the car from a cold machine to an emotional and intelligent "partner". Of course, this concept is also used in Ruicheng CC. For example, in the design of lights with "breathing function", when the vehicle is unlocked, the welcome lights will be lit first, and the front and rear headlights will "breathe and flash". When the door is opened, the full LCD instrument panel will play the welcome animation, and the atmosphere lights, background lights and one click Start button lights in the vehicle will light up or breathe and flash in an orderly manner.


In general, among the domestic independent brands, Changan Ruicheng CC can be regarded as a leader both externally and internally, with more style than some joint venture vehicles. Would you not be excited about such a car?

The core of the air purification system in the vehicle is the air purifier. The air purifier, also known as "air cleaner", air purifier and purifier, refers to products that can absorb, decompose or transform various air pollutants (generally including decoration pollution such as PM2.5, dust, pollen, peculiar smell and formaldehyde, bacteria and allergens), and effectively improve air cleanliness, The main application fields are household, commercial, automobile, industry, building, etc.There are many different technologies and media in the air purifier, so that it can provide users with clean and safe air. Common air purification technologies include: adsorption technology, negative (positive) ion technology, catalysis technology, photocatalyst technology, super structured light mineralization technology, HEPA high-efficiency filtration technology, electrostatic dust collection technology, etc; Material technology mainly includes photocatalyst, activated carbon, synthetic fiber, HEPA efficient material, anion generator, etc. The existing air purifiers are mostly composite, that is, a variety of purification technologies and material media are adopted at the same time.Step 1: its working principle is to monitor the air quality and smell in the vehicle in real time through a sensor. When the system thinks that the air pollution in the vehicle exceeds the standard, the system will first command the air conditioning system to use external circulation to inhale fresh air. After inhalation, the fresh air will pass through a filter element made of grape seed polyphenols to filter pollen, odor and some allergens.


Step 2: the humidity sensor inside the interior rearview mirror adjusts the dehumidification mode of the air conditioner by detecting the fog of the window to avoid excessive drying of the air. This function can only monitor the humidity and adjust the dehumidification mode of the air conditioner, and does not have the humidification function.Step 3: the filtered fresh air comes to the lower part of the central console through the air duct. There is a fragrance device equipped with green leaf ethanol and fragrant wood spices, which will melt the natural fragrance of some trees and green leaves into the air.Step 4: when the air reaches the air outlet of the air conditioner, the negative ion generator produces a large number of negative ions and mixes them into the air. Finally, the system simulates the natural wind flow mode and frequency according to the sunlight exposure and the outside temperature, and blows the air into the cabin to create a comfortable feeling of walking through the forest.
In addition, if the system detects that the external air is bad, it will automatically switch to internal circulation mode like other intelligent automatic air conditioners. However, after switching, the air conditioning filter element and negative oxygen ion generator can still filter and purify the air in the vehicle, which is also a major feature. The purpose of this system is to free the driver and passenger from excessive tension through the flowing wind and aromatic air, keep a clear mind and enter a relaxed state with high attention and concentration.
Finally, a temperature and humidity sensor that can be used in the vehicle air purification system is recommended. The high-quality temperature and humidity sensor imported by industrial mining network from abroad is the digital temperature and humidity sensor - htu21d. Htu21d is a plug and play humidity and temperature composite sensor, which is an ideal choice for OEM applications that need reliable and accurate measurement. It is a series of modular products designed for transportation applications. It adopts DFN package suitable for reflow soldering, and the size is only 3 x 3 x 1mm; Provide corrected, linear I C digital output signal. The temperature sensing element of the sensor can effectively measure gas, liquid or solid. In addition, the sensor can detect low power, and the checksum is used to improve communication reliability. All this benefits from its high-performance sensitivity, measurement accuracy and stability. At the same time, the easy installation thread structure provides reliability in harsh environments. The numerous mechanical and electronic interfaces of htu21d temperature and humidity sensor simplify the installation, which can not only meet the specific application needs of different customers, but also be easily compatible with most existing applications.

Hong Kongs Highways Department has defended its decision to keep the public in the dark for more than a month about the partial suspension of the air purification system the largest of its type in the world at the new Central-Wan Chai Bypass, saying it needed time to grasp the situation.Director of Highways Jimmy Chan Pai-ming said on Wednesday the department was investigating why seven out of 15 fans had been damaged and mounting bolts had come loose at the green ventilation facility near Causeway Bay, one of three such plants along the 4.5km link.The consultant of the air treatment system, Aecom, told the department on March 5 that the contractor, a Leighton Asia-led joint venture, found the damage about a month after the bypass opened to traffic on January 20.As a result of the defects and for safety reasons, the operation of the air purification system and ventilation building has been suspended since the end of February.We did not cover up the issue, Chan said a day after the department divulged the information. We needed to study the scope of the issue and the extent of the damage to the fans we also needed to gauge the air quality, which takes time.The much-trumpeted HK$250 million (US$32 million) air purification system is a highlight of the HK$36 billion bypass, a short cut between North Point and Central that took almost 10 years to build and includes a 3.7km tunnel and a flyover.When we have the results of the investigation, we will take the necessary action and follow up with the parties concernedJimmy Chan, highways directorThe tunnels air purification system the first in Hong Kong and the largest of its kind in the world in terms of the air volume handled can remove at least 80 per cent of harmful suspended particulates and nitrogen dioxide, two key roadside pollutants.Although the Causeway Bay one was not operating, the other two facilities in Central and Wan Chai worked properly and the overall air quality did not show any signs of deterioration, Chan said.It is not a very common situation and that is why we are carrying out a detailed investigation to find out the cause of the problem, what led to the damage to the ventilation fans, he said. When we have the results of the investigation, we will take the necessary action and follow up with the parties concerned.Chan added the system remained at a trial stage, which meant the contractor would foot the bill on any maintenance costs.Stephen Ng Kam-chun, chairman of Wan Chai District Council, said it was not ideal that the government did not reveal the issue until Tuesday.It could have done better in notifying the public, he said.He urged the government to consider whether Leighton should be granted contracts in future in light of the MTR Corporations troubled Sha Tin-Central rail link, on which the company was a contractor.Why does the air treatment system and the other two ventilation buildings work properly but not the one in Causeway Bay? Did the installation process go wrong? he asked. I have lost confidence in Leighton.World Green Organisation CEO William Yu Yuen-ping urged the government not only to investigate the reasons for the damage, but also to prevent it from happening again at any of the ventilation facilities.I am surprised that it happened in the early days of operation, he said.Repairs were under way and some components had been imported, Chan said.We hope the maintenance work will be completed by the end of April, he said.Leighton declined to comment while the Post reached out to Aecom.More from South China Morning Post:This article first appeared on South China Morning PostFor the latest news from the South China Morning Post download our mobile app. Copyright 2019.
