The amount of refrigeration (heat), energy efficiency and noise are the three most important indicators for measuring the advantages and disadvantages of air conditioners.
Cooling (heat) amount
The amount of heat removed from the confined space by the air conditioner during the cooling (heat) operation, the legal unit of measurement is W (Watts).
The national standard stipulates that the actual cooling capacity of air conditioners should not be less than 95% of the rated cooling capacity.
Energy efficiency ratio
Also known as the coefficient of performance, it refers to the ratio of the cooling capacity to the cooling power during the cooling operation of the air conditioner, in units of W/W.
According to national standards, the energy efficiency ratio of 2500W air conditioners is 2.65; the energy efficiency ratio of 2500W to 4500W air conditioners is 2.70.
noise
The noise generated during the operation of the air conditioner is mainly generated by the internal evaporator and the external condenser.
The national air conditioner indoor unit with a cooling capacity below 2000W shall not exceed 45 decibels, the outdoor unit shall be no more than 55 decibels, the 2500W to 4500W split air conditioner indoor unit noise shall not exceed 48 decibels, and the outdoor unit shall be no more than 58 decibels.
