The energy efficiency ratio (EER) of an energy class air conditioner represents the unit power cooling capacity of the air conditioner.

The higher the EER value, it means that more heat is absorbed by evaporation in the air conditioner or less power is consumed by the compressor,

that is, the less electricity cost, the cooler the effect is.

Many consumers think that split-type air conditioners are more economical and more power efficient.

In fact, there is a misunderstanding.

From the perspective of energy efficiency ratio, the central air-conditioning energy efficiency ratio energy guide label requirements is often higher and more energy-efficient than split-type air conditioners.

The energy guide label air conditioner of general household split air conditioners  a+++ air conditioner consumption is about 2.3 ~ 3.6,

while most energy efficient inverter air conditioner central air conditioners can reach more than 6.0,

and the energy efficiency ratio far exceeds the level of ordinary air conditioners such as cabinet type and split type.

Simply put, when the cooling capacity is the same, the central air conditioning energy consumption is more energy efficient than the split air conditioner.
