A directly actionable refrigerant procurement checklist: verify supplier filing status before purchasing, confirm our own use/servicing filing obligations, request variety/quantity/specification information and shipping documents during transactions, keep ledger records for at least 3 years, plus the HFCs phase-down timetable and annual filing windows.
Read More →Under the Kigali Amendment, R22, R134a, R404A, R410A and their blends are all controlled substances. Based on MEE Huan Daqi [2026] No. 8 and current policies, this guide covers filing categories, procedures, required materials and key deadlines for sellers, users, servicers and recyclers of refrigerants.
Read More →As the Kigali Amendment to the Montreal Protocol is implemented domestically, HFCs production quotas are further tightened. Prices of high-GWP fluids such as R134a, R404A and R410A trend upward, while low-GWP alternatives accelerate their substitution.
Read More →As the controlled HCFC R22 is phased out, in-service systems face retrofit decisions. This article systematically compares R407C, R410A and R32 across thermodynamic performance, retrofit cost and system adaptability.
Read More →Blends such as R404A, R407C and R410A differ fundamentally from single-component refrigerants in charging method. Wrong vapor charging causes composition segregation, capacity loss and even compressor damage.
Read More →With a GWP of only 3 and excellent thermodynamic properties, R290 is expanding in home A/C, heat pumps and small commercial refrigeration, and the supply chain is maturing.
