Stepping into Henan Kingclima Industry Co., Ltd., located in the Zhengzhou High-tech Industrial Development Zone, the modern production lines operate smoothly in the workshop. Quality control staff are using precision instruments to test products, and an engineer is explaining the company's latest patented technologies to visitors.
Henan Kingclima Industry Co., Ltd. is located at No. 283, West Third Ring Road, Zhengzhou High-tech Industrial Development Zone, Henan Province. Founded in 2018, this company has become a leading player in the automotive refrigeration industry.
Kingclima Industry has accumulated rich industry experience in automotive refrigeration. Its products are used in conjunction with well-known automakers such as BYD, Yutong Bus, and Geely Automobile. Some products are also sold to the United States, Russia, Italy, Brazil, and other countries and regions. The company has established branches in three countries, including Russia, and has a professional e-commerce operation team and multiple online platforms.

01 Factory Visit Preparation

Before entering the factory, rigorous preparation is essential. Before entering the company's production site, all visitors must register and obtain a "visitor's pass" as required.
Safety regulations are paramount. Personal protective equipment (PPE) must be worn when entering the production area, and safety helmets must be properly fastened with chin straps. Long hair must be tied up. All visits must be guided by company personnel along designated routes.
These details reflect Kingclima Industrial's standardized management and emphasis on safe production. This rigorous attitude permeates every aspect of the company's operations.

02 On-site Observation

I. Stepping into the production workshop, advanced production equipment operates smoothly, and workers skillfully operate the machines. This is the first impression visitors have of Kingclima Industrial's production line.
The workshop layout is meticulously designed, with rational space utilization, greatly saving material handling time and improving operational efficiency. Workers work standing up, yet are full of energy, demonstrating professionalism.

On specific production lines, visitors can observe the manufacturing process of key products up close. During the tour, accompanying personnel will provide detailed explanations of the production processes, equipment characteristics, and the future working environment.

II. This workshop is an automated refrigerant (Freon) filling station for parking air conditioning systems, employing a high-pressure liquid filling process: After pre-vacuuming (vacuum degree ≤50Pa), the system uses a servo-controlled filling gun to precisely connect with the high-pressure interface (H port) of the air conditioning pipeline. R134a refrigerant is quantitatively injected according to the vehicle model's calibration parameters (500-800g/unit). During the process, the pipeline pressure is monitored in real time (high pressure during filling ≤1.6MPa), and the interface sealing is tested using a leak detector (accuracy 10⁻⁶Pa・m³/s).

The production line is equipped with a dual-rail conveyor system, combined with visual positioning to achieve automatic filling gun docking. The single-unit filling cycle time is ≤40 seconds. A refrigerant recovery device is also installed to ensure that the workshop environment concentration meets the GB/T 7778-2017 safety standard. All process data (filling volume, pressure curve) is uploaded to the MES system in real time to ensure batch consistency.

III. This room is specifically for testing the "heat resistance and cooling" of parking air conditioners. First, turn on all the heaters around the room to stabilize the temperature at around 37 degrees Celsius (approximately the temperature inside a car under the hot summer sun), simulating the high-temperature environment encountered during actual air conditioner use.

Once the temperature stabilizes, connect the air conditioner to the power supply and pipes, and run it at its highest cooling setting. We mainly observe the following: First, whether the air vents can cool down quickly; ideally, the air coming out should be at least 27 degrees Celsius lower than the room temperature (for example, if the room temperature is 37 degrees Celsius, the air vents should cool down to around 10 degrees Celsius to be considered acceptable); second, the air conditioner's "heart," the compressor, and monitor its power consumption; it shouldn't fluctuate wildly beyond the normal range; third, the refrigerant pressure in the pipes; the high pressure should not exceed 18 atmospheres, and the low pressure should not be lower than 2 atmospheres, otherwise there may be a leak or blockage.

This air conditioner needs to run continuously for two hours in a room at 37 degrees Celsius. During this time, you have to monitor the room temperature to ensure it doesn't fluctuate, and you also have to touch the air conditioner's power cord and connectors to check if they're hot. After testing, you have to apply soapy water to the pipe connections to check for any bubbling or refrigerant leaks.

All this trouble is to ensure that the air conditioner can withstand the heat under the hot summer sun, keep the car cool, and doesn't break down easily.

03 Technological Innovation

Kingclima Industrial has invested significantly in technological innovation, possessing 21 patented technologies and 2 software copyrights. The company's recently announced invention patent, "Condenser and its Application in Refrigeration Machines," is one such technological innovation achievement.

In the product display area, visitors can see the company's diversified product line, including innovative products such as automotive air conditioning systems and DC air conditioners.

Company technicians will demonstrate the performance and functional features of the products on-site, explaining their application scenarios and technological advantages, allowing visitors to fully understand the products' market competitiveness.

By the end of the visit, Kingclima Industrial has demonstrated its complete system from R&D and production to quality inspection to its clients.Adhering to the philosophy of "pursuing excellence and unwavering commitment," the company is dedicated to building an open, happy, and fulfilling growth and entrepreneurship platform.
