Warning: Combustible Materials

For appliances with flammable refrigerants, it is necessary to test the arcs and sparks generated by electrical components, such as relays requiring explosion-proof certification.

According to the control requirements of the Kigali Amendment and in combination with the maturity of industry substitution technologies, HFC reduction and substitution will be implemented in different industries and stages.

Starting from January 1, 2029, it is prohibited to produce household air conditioners (room air conditioners) filled with refrigerants with a global warming potential (GWP) greater than 750 for domestic sales, except for household multi split air conditioning (heat pump) units.

Interpretation: Ban GWP>750 → R134a, R410A are out, R32 dominates

High-frequency non-compliance points: The indoor unit panel of the air conditioning cabinet is detachable, and the fan lacks a protective cover. This fails to meet the requirements of Clause 20.2 in GB/T 4706.1-2024.

High-frequency non-compliance point: The temperature sensing probe lacks sufficient protection and fails to meet the requirements for Class II construction as stipulated in Clause 8.2 of GB/T 4706.1-2024.
