R290 Refrigerant and Monoblock Unit: Collaborative Innovation Path for Environmental Protection Cold Chain

Driven by the goal of carbon neutrality, the refrigeration industry is accelerating its transition towards low-carbon. As a natural working fluid, R290 has become an ideal choice to replace traditional fluorocarbons due to its zero ozone layer depletion potential and low global warming potential. The compact design of the Monoblock Unit provides a technical carrier for the safe application of R290.

Monoblock Unit integrates the refrigeration system into a single box, reducing pipeline connections and refrigerant charging, significantly reducing the risk of R290 leakage. Taking commercial refrigerators as an example, the R290 integrated refrigeration system reduces refrigerant filling by 60% compared to traditional split machines. At the same time, by optimizing the air duct design, energy efficiency is improved by 12% -15%, meeting the EU ERP energy efficiency standards.

In terms of safety performance, the built-in leak detection module of the Monoblock Unit can monitor the concentration of refrigerant in real time. Combined with explosion-proof motors and sealing structures, it ensures stable operation of the equipment in crowded scenarios such as supermarkets and convenience stores. At present, multiple European companies have applied R290 Monoblock Units to dairy products and pharmaceutical cold chains, verifying their commercial feasibility.

With the tightening of international environmental regulations, the combination of R290 and Monoblock Units may become the mainstream solution for small and medium-sized refrigeration equipment, promoting the industry's evolution towards green and sustainable direction.
