The development trend of industrial refrigerants

Selection factors of industrial refrigerants

Environmental friendliness: ODP and GWP are key indicators that must comply with the requirements of the Montreal Protocol and the Kigali Amendment.

Safety: Toxicity, flammability, explosion limits, etc. must meet safety standards.

Energy efficiency: The thermodynamic performance directly affects the refrigeration efficiency and energy consumption.

Cost: including refrigerant price, equipment investment, and operation and maintenance costs.

Compatibility: It needs to be compatible with lubricating oil, sealing materials, etc.

The development trend of industrial refrigerants

Environmental Protection: Gradually phasing out high GWP refrigerants, promoting natural refrigerants (such as ammonia and carbon dioxide) and new HFOs.

Efficiency: By optimizing the design of the refrigeration system, the energy efficiency ratio (COP) can be improved.

Safeization: Develop low toxicity, non flammable or slightly flammable refrigerants to reduce safety risks.

Intelligence: Combining IoT technology to achieve intelligent monitoring and optimization of refrigeration systems.

Typical application cases

Large cold storage: ammonia refrigerant is preferred due to its high efficiency and low cost, but safety management needs to be strengthened.

Supermarket cold chain: Carbon dioxide transcritical refrigeration systems are gradually becoming popular, balancing environmental protection and energy efficiency.

Chemical cooling: Choose Freon or natural refrigerants according to process requirements to ensure stability and safety.
