How to read air conditioner nameplate parameters? What does KFR means?
Air conditioner nameplate is an important basis for understanding the performance, specificaties, and usage conditions of an air conditioner. The parameters on it involve key information such as cooling/heating capacity, energy efficiency rating, and power supply requirements. The model numbers of many air conditioners are a string of letters and numbers, which are not very easy to understand.
Whether you are choosing to buy an air conditioner or repairing one, it is necessary to understand the basic information of the air conditioner from the nameplate.
Nameplate Reading
1. Main Parameter
The air conditioner nameplate is usually located on the side or back of the unit. While it contains numerous parameters, their logic is clear and can be primarily divided into three categories: product model, performance parameters, and safety & certification information. The specific interpretation is as follows:
Product Model (Using “KFR-50GW/BP3DN8Y-PH200 (1)” as an example)
The model number is the identifier for the air conditioner. The letters and numbers can be used to quickly determine the air conditioner’s type, functie, and specifications.
Starting letters (KFR): Represent the air conditioner type and function (to be explained in detail later).
Numbers (50): Represent the cooling capacity. The unit is “100W”, meaning 50 indicates a cooling capacity of 5000W (1 HP ≈ 2500-2800W, so 5000W is approximately 2.0HP).
Cooling capacity is the core parameter for selecting an air conditioner and must be matched to the room area (bijv., 10-15 sq.m is suitable for 1 PK, 15-20 sq.m is suitable for 1.5 PK, 25~35 sq.m is suitable for 2.0 PK,enz).
Subsequent letters:
-
G: Represents Wall-mounted indoor unit (Cabinet unit is “L”).
-
W: Represents Outdoor unit.
Additional function codes (bijv., BP3DN8Y):
-
BP: Omvormer (non-inverter air conditioner models don’t have this identifier).
-
3D: Represent 3D Airflow or Intelligent Temperature Control.
-
N: Represent Eco-friendly Refrigerant (bijv., R410a or R32).
-
Y: Remote control function.
Energy Efficiency Label (bijv., PH200 (1)):
-
The number “1” represents Level 1 Energie-efficiëntie (A lower level indicates higher energy savings).
Cooling/Heating Capacity: Unit is W. A higher value indicates stronger cooling/heating ability (bijv., Cooling Capacity 5000W, Heating Capacity 5500W).
Cooling/Heating Power Input: Unit is W. Represents the power consumption during cooling/heating operation (Lower power input means higher energy savings. This should be evaluated together with the energy efficiency rating for a more accurate assessment).
Auxiliary Electric Heating Power: Some air conditioners require auxiliary electric heating during heating mode. Unit is W. This power consumption is additional.
Capaciteit: Cooling 18,000btu/h means rated cooling capacity (btu is an energy unit to measure air conditioner), 5,500~20,000btu/h means INVERTER air conditioner cooling capacity scope at different ambient temperature (non-inverter air conditioner no this scope).
Current: Cooling 7.3A means rated current on cooling mode, 2.4~10.2A means INVERTER air conditioner cooling current scope at different ambient temperature (non-inverter air conditioner no this scope).
IEC/EN60335: International standard for air conditioner with excellent performance.
Energy Efficiency Ratio (APF/SCOP):
-
For inverter air conditioners, refer to APF (Annual Performance Factor).
-
For non-inverter air conditioners, refer to EER (Energy Efficiency Ratio).
A higher value indicates better energy efficiency (Typisch, Niveau 1 Energy Efficiency requires an APF ≥ 4.5).
Max. Pressure discharge (high side): 4.5 MPa
Max. Pressure suction (low side): 1.9 MPa
Refrigerant Charge: Max filling weight
KFR Meaning
The model number usually starts with letters like “KFR” which is a common designation in systems like China’s GB standards. Here is a breakdown:
-
K: Stands for “Air Conditioner.”
-
F: Stands for “Split Type.” This indicates the unit has separate indoor and outdoor units.
-
R: Stands for “Heat Pump.” This means the unit can provide both cooling and heating.
Daarom, “KFR” designates a Split-Type Heat Pump Air Conditioner.
A model that only has “KF” would be a cooling-only split system. The numbers following these letters often indicate the cooling capacity (see above).
KFRd: De “D” represents auxiliary electric heating, meaning that in addition to the heat pump, it also supports auxiliary electric heating to enhance heating performance.
KC: Represents a window-mounted air conditioner, which is a single unit integrating both the indoor and outdoor sections, and installed in a window.
Conclusie
Understanding the nameplate parameters of air conditioner is a fundamental skill for both users and installation or maintenance personnel.
Each piece of data on the nameplate reflects the unit’s performance, veiligheid, and energy consumption level.
Only by truly understanding these parameters can you select the right model, install it properly, and use it efficiently—allowing the air conditioner to deliver optimal performance and enjoy a longer service life.
