To select the energy saving air conditioner is suitable for home, consumers can select the following suggestions:

Appropriate capacity

Typically, for bedroom and living room in the household, you can choose a machine with a capacity of about 600Btu / h per square meter room. For example, less than 15, 20, 30, 40m2 will use the machine with a capacity of respectively 9,000 and 12,000 BTU / h (equivalent to your horse 1.5) and 17,000 and 22,500 BTU / h (equivalent to 2 horse).

Select one-way or two-way air conditioner in accordance with climate, weather

Hot southern climate conditions throughout the year so the choice cold DC air conditioner will fit. Northern climate conditions, you should choose a 2-way air-conditioning cooling and heating. If in the home with children and the elderly, the two-way air conditioner as needed.

Air conditioner using inverter technology

Currently on the market, the line of air conditioners using inverter technology is favored by saving a large amount of energy, about 30-60% compared to conventional air conditioning, just a cold or warm faster .

The air conditioner uses inverter technology is designed as a regular air conditioner, but use the power conversion circuitry to automatically adjust the electrical parameters such as voltage, amperage … This conversion circuit controls the rotation of the compressor, resulting in power conditioner control. When enough cold or warm rooms, air conditioning inverter automatically reduces the operating power, to maintain the cold temperature that the user has previously installed.


The air conditioner manufacturers try to develop brand with advanced technology. In particular, considerable attention is technology Plasmaster of LG electronics firms. The air conditioner lines using this technology outside the maximum energy efficiency, and ion generators help & auto cleaning, improving efficiency air filter, kill bacteria, create a pleasant space, comfort and enhanced skin moisturizing.
Air conditioners labeled energy saving

The State is encouraging firms to produce products that save energy. Accordingly, on 1/1, Decision 51/QD-Ttg of the Prime Minister on the energy labeling of electrical equipment has been applied. Thus, the labeling of energy on air conditioning products will help consumers better identify, correct choice of energy-saving products.

However, the state still lacks the testing agency, so other brands can not apply. To implement this policy, the Company LG Electronics Vietnam effort and initiative in completing on time for the energy labeling of air-conditioning products in foreign countries and pioneering application in Vietnam market . According to a survey in the large electronics center in the country, are energy stamps appear in almost any LG air conditioning product.

According to the regulations of the Ministry of Industry and Trade, in saving energy scale was rated from 1 star to 5 star, air conditioning inverter product line of LG has achieved energy savings of 5 stars (the line of air conditioning products LG also has other 2-3 stars). This prove the optimal power consumption and the strength to compete with the same products of other brands.
