1. Energy Label
The energy label demonstrates the energy-saving capability of the device, usually affixed to devices with energy efficiency ratings meeting or exceeding high standards from 1 star to 5 stars regulated by the Ministry of Industry and Trade.
The energy label on electrical appliances will display information including: product code/name, manufacturer, certification number, power consumption, energy efficiency rating. The higher the star rating, the greater the energy savings. A 5-star label represents the highest level of energy-saving electricity consumption.
Therefore, before selecting an air conditioner, users should pay attention to the energy label information affixed to the device.
2. Inverter Technology
Inverter Air Conditioner operates using variable frequency compressor technology, ensuring stable room temperature with less energy consumption.
Inverter technology enables air conditioners to operate smoothly and quietly with optimal energy consumption, hence the cost is usually higher compared to regular models of the same brand and capacity. Therefore, users should consider financial conditions and usage needs to decide whether to buy an Inverter air conditioner or not.
3. BTU or HP Rating
When users purchase an air conditioner, they will be advised on the capacity measured in units such as 1HP, 2HP... However, for some air conditioner models, the capacity may be measured in BTU units as indicated on energy labels.
BTU stands for British Thermal Unit - a unit of heat measurement commonly used in the United States to measure the cooling or heating capacity of appliances. BTU/h or BTU indicates the amount of energy required to increase 1 pound (454g) of water by 1 degree F (Fahrenheit). You can convert BTU to other units using the formula: 1 BTU equals 1055 J = 0.293 kW; 1 HP equals 9000 BTU.
Understanding the cooling capacity of the air conditioner will help users easily choose the right air conditioner for their needs. Currently, the smallest cooling capacity of air conditioners in Vietnam is around 9000 BTU/h, equivalent to 1 HP. The electricity consumption in 1 hour of the air conditioner will be 9,000 x 0.293W = 2637W.
BTU reflects the cooling capacity of an air conditioner, not the electricity consumption.
4. Refrigerant gases R22, R33, R410A
The cooling technology of air conditioners relies on the heat absorption reaction of gases through the compressor cycle. Therefore, gas is also one of the important components of air conditioners that users need to pay attention to.
Currently, there are 3 types of refrigerant gases used including R410A, R22, and R32. R22 gas is the first type used in air conditioners with the advantage of safety, no combustion, but it harms the ozone layer so it is not used.
R410A gas was born to replace R22 gas, providing 1.6 times higher cooling efficiency, helping to save electricity, not harmful to the ozone layer but has the disadvantage of being difficult to maintain and expensive.
R32 gas is currently widely used in new generation air conditioners. The advantage of this gas is high safety, good environmental protection, cooling efficiency increases by 1.6 times compared to R410A for better energy savings.
Above are the key specifications you need to grasp when purchasing an air conditioner. Remember to save them for reference and application. Don't forget to follow Mytour for quick updates on the most useful information.
