This article thoroughly explains the suitable models for low GWP environmentally friendly refrigerants and the upgrading direction of foreign trade refrigeration equipment.

With the continuous tightening of global environmental protection policies, high GWP refrigerants are gradually restricted in use by various countries, and the export threshold of refrigeration equipment is constantly rising. Many foreign trade manufacturers still use traditional refrigerants to match their units, and when exporting to countries in Europe, Asia, and Southeast Asia, they encounter problems such as customs clearance obstacles and market sales bans. To adapt to the low-carbon trend and develop refrigeration equipment compatible with low GWP refrigerants, it has become a core breakthrough for manufacturing enterprises to expand their overseas markets.
I. Industry Background for the Popularization of Low GWP Refrigerants
The European Union and North America have first introduced schedules for the elimination of refrigerants, gradually reducing the use of high warming potential refrigerants such as R404A; countries in Southeast Asia and the Middle East have also followed environmental regulations, and new cold storage and industrial cooling projects are prioritized to use low GWP refrigerant models. Industry research data shows that the export growth rate of refrigeration equipment compatible with environmentally friendly refrigerants has far exceeded that of traditional models in the past three years, and the market share of products that do not meet refrigerant standards has continued to shrink.
Low GWP refrigerants have higher requirements for the sealing of the unit's piping, the tolerance of the compressor, and the pressure-bearing capacity of the heat exchange system. Ordinary standard units cannot directly fill the new refrigerants and must be specifically optimized for the piping, sealing components, and heat exchanger structure.
II. Core Structural Upgrade of Refrigeration Equipment Compatible with Environmental Friendly Refrigerants
First, thickened copper tubes and high-precision welding techniques are used to improve the pressure-bearing and gas-tightness of the piping, eliminating the leakage of the new refrigerants in trace amounts; second, the heat exchange area of the heat exchanger is optimized to offset the difference in heat exchange efficiency of the new refrigerants, ensuring stable energy consumption under the same cooling capacity; third, specialized compressors and expansion valves compatible with the new refrigerants are provided to avoid equipment failures caused by incompatible parts; fourth, the pressure protection parameters of the electronic control system are adjusted to match the operating pressure range of the environmentally friendly refrigerants.
Simple replacement of refrigerant models without upgrading the entire machine structure is prone to problems such as insufficient cooling, high-pressure alarms, and accelerated compressor wear, and cannot operate stably for a long time.
III. Reference for Refrigerant Selection in Different Overseas Markets
The European and American markets mainly promote CO₂ cascade units, R454C, and R134a low GWP refrigerant models; the Southeast Asian market considers cost, and uses low GWP mixed refrigerants mainly; in high-temperature regions in the Middle East, it is necessary to simultaneously consider refrigerant compatibility and the renovation of heat dissipation structures with high-temperature resistance. Before export, it is necessary to conduct research on the mainstream compliant refrigerants in the target market and adjust the unit configuration as needed.
IV. Advantage of Source Factory R&D and Complementary Support
Suzhou Xueying Refrigeration continuously follows the updates of global refrigerant policies, relying on more than ten years of heat exchange equipment research experience, it can customize low GWP environmentally friendly refrigerant-specific units for customers in export countries, complete the upgrade of the piping, compressor, and heat exchange system. The complete cold pressure and long-term load special tests are completed at the factory, and the complete compliance detection report of refrigerants is provided to meet the entry review requirements of local customs and engineering contractors in various countries, and to adapt to foreign trade export projects in the food, medicine, chemical, and agricultural scenarios. The enterprise can also provide technical explanations of the refrigerant compatibility solution to facilitate overseas customers to complete local registration.
V. Long-term Business Advice for Foreign Trade Manufacturers
Pre-prepare multiple standardized models of environmentally friendly refrigerants to reduce the customization and modification cycle; actively explain the local refrigerant control policies to overseas customers and recommend compliant models; continuously optimize the energy-saving heat exchange structure, taking into account both environmental protection and low energy consumption, to enhance the competitiveness of the product in the overseas market. Summary
Low GWP environmentally friendly refrigerants represent an irreversible trend in the global refrigeration industry. Exported equipment must undergo specialized upgrades to its overall structure. Source factories with independent R&D capabilities and the ability to conduct multi-condition tests can quickly adapt to the refrigerant regulations of various countries, helping overseas cooperative customers avoid customs clearance and market sales risks, and steadily expand global cold chain channels.
