Exploring a Low-Carbon Cold Chain Future | Snowman Group at the China Refrigeration & Cold Chain Expo (Kunming)

release time：2025-11-27 10:52:34

At the China Refrigeration & Cold Chain Expo (Kunming) held on November 20–22, Snowman Group participated together with its regional partner,  KUMING KULE representing the RefComp brand in Southwest China. Snowman Group’s Marketing Director, Chen Wei, delivered a keynote speech on global low-carbon cold chain technology trends.

√Ammonia Refrigerants: Enhancing the Efficiency and Safety of Natural Working Fluids

With the resurgence of natural refrigerants, ammonia has regained attention for its high energy efficiency and low carbon footprint.

Snowman Group’s third-generation semi-hermetic ammonia screw compressor features a shaft-seal-free design that eliminates leakage risks. Combined with SRM high-efficiency rotor profiles and permanent-magnet variable-frequency technology, the overall efficiency significantly surpasses traditional open-type piston models—offering safer and more energy-efficient options for cold chain applications.

√ HFO Refrigerants: A Mature Alternative Under Global Emission-Reduction Policies

The Kigali Amendment is accelerating the adoption of low-GWP refrigerants. For applications where ammonia is not suitable, RefComp has accumulated extensive experience with HFO-based systems:

R454C: Over 40 parallel compressor racks delivered in 2024–2025, primarily for the European market.

R449A: Over 60 racks delivered in 2024–2025, serving Hong Kong & Macau, Japan, the U.S., and parts of Europe.

These achievements demonstrate RefComp’s ability to deliver safe, efficient, and reliable solutions that offer viable low-carbon alternatives for diverse global markets.

★Global Refrigeration Technologies Are Moving in Two Clear Directions:

1. Maximizing the performance advantages of ammonia in suitable applications;

2. Applying low-GWP HFO refrigerants as transitional solutions in other applications to drive efficiency improvements and emission reduction.

Aligning with global decarbonization trends, Snowman Group will continue to deliver safe, efficient, and sustainable refrigeration solutions through technological innovation and professional service.
