Smart Shopping Tips for Air Conditioners:

Horsepower of Air Conditioner

The greater the number of horses, the higher the cooling capacity, but the greater the power consumption. Users can refer to the area of ​​the room and choose the appropriate number of air conditioners.

Cooling Capacity of Air Conditioner

The refrigeration unit of an air conditioner is usually kilowatts (kW) or British thermal units per hour (BTU/h). A higher value reflects the higher cooling capacity of the air conditioner. Users can refer to the room area and choose the appropriate cooling capacity of the air conditioner.

Fixed-frequency and Inverter Air Conditioner

The compressor of the fixed frequency air conditioner can only rotate at one speed when it is operating. When the air conditioner reduces the indoor temperature to the set level, the compressor will stop operating. Then when the room temperature rises, the compressor will restart to lower the room temperature to an appropriate level. Therefore, the fixed frequency air conditioner is constantly switched on and off according to the room temperature. The room temperature will be more unstable and consume a lot of power. Therefore, the price of the fixed frequency air conditioner is generally cheaper.

When the inverter air conditioner detects that the room temperature reaches a certain temperature, the air conditioner will automatically reduce the compressor speed and continue to operate, avoiding frequent switching of the compressor parts, while stably controlling the indoor temperature, so the inverter air conditioner is more efficient It can save energy and save up to 40% of electricity. Therefore, inverter air conditioners are more expensive.

Energy Label

The energy label for air-conditioners indicates the energy efficiency levels from the highest level 1 to the lowest level 5.

The window air conditioners with the "Level 1 Energy Label" save 11% of electricity than the "Level 3 Energy Label" and are more than the "Level 5 Energy Label" Save 25% more power.

The "Level 1 Energy Label" split air conditioner saves 36% of electricity compared to the "Level 3 Energy Label" and 61% more electricity than the "Level 5 Energy Label". In addition, the "cooling capacity" and "annual power consumption" indicated on the energy label are compared.

Air Conditioner Use and Maintenance Tips:

  1. When turning on the air conditioner, you need to close the doors and windows. At the same time, you can turn on the fan and draw the curtains to help lower the room temperature fast and save electricity.
  2. Using the swing function of the air-conditioner. Cool air is blown out from the air conditioner evenly. It helps reducing indoor temperature.
  3. Avoid any objects blocking the air inlet and outlet of the air conditioner.
  4. The air outlet of the air conditioner should not be directly blown to the ceiling or wall at close range. It helps reducing moisture and mold due to temperature change frequently.
  5. The air conditioner should be shut down and rested every 12 hours of operation to avoid bad effect of the lifespan.
  6. Restart the air conditioner at least 5 minutes after shutting it down to avoid reopening it for a short time.
  7. Wash the dust screen and wipe the air outlet every 2 weeks. Use shower water to clean the dirt on the dust screen and the air conditioner cover. Do not use a brush to clean it, because it will enlarge the mesh of the dust screen and affect the dust isolation function.
  8. The dust filter with anti-bacterial function does not need to be cleaned, but it is recommended to replace the dust filter with a new one in one to two years to ensure the best filtering effect.
  9. Use a suitable air conditioner cleaner regularly to clean the cooling metal pieces of the air conditioner to reduce the growth of bacteria.
