Now all air conditioners are fluorine-free.

At present, fluorine-free inverter air conditioner is the most environmentally friendly air conditioner. The previously used freon air conditioner has been phased out, and the fluorine-free environmental protection refrigerant R4 10A is its main environmental protection substitute. Therefore, the air conditioner using fluorine-free environmental protection refrigerant R4 10A instead of the original traditional refrigerant is called "fluorine-free" air conditioner. Refrigeration principle of fluorine-free frequency conversion air conditioner: the generated refrigerant vapor condenses into refrigerant liquid in the condenser, and the liquid refrigerant enters the evaporator after throttling through the U-tube. The liquid refrigerant is sprayed by the evaporator at low pressure and then evaporated, which absorbs the heat of the refrigerant and produces refrigeration effect. Advantages of fluorine-free inverter air conditioner: fluorine-free inverter air conditioner has faster efficiency, higher energy efficiency and more energy saving. Combined with DC motor, intelligent environment detection defrosting, leading fluorine-free new refrigerant and four energy-saving guarantees of ultra-low temperature -20℃ start, fluorine-free inverter air conditioning refrigeration (heating) is faster. Using the inverter air conditioner with the highest energy efficiency for 24 hours saves electricity by 5.2 degrees compared with ordinary inverter air conditioners, and the electricity saved is equivalent to the electricity consumption of 94 1 1W energy-saving lamps for 5 hours every day, which is equivalent to emitting 4 kilograms of carbon dioxide into the atmosphere, which is energy-saving and environmentally friendly.
