Using smart air conditioners and washing machines helps reduce electricity bills

The online discussion on electricity prices organized by Thanh Nien Newspaper received many questions from readers about how to use devices to save electricity.

Reader Nguyen Dinh Thang (Thu Duc, Ho Chi Minh City) asked: EVN often recommends customers to reduce the use of air conditioners, but that is difficult to do in hot weather. So how does EVN encourage the use of air conditioners? If air conditioners are used economically, what is the average reduction rate for a household?

Many other readers also wonder: Is it more economical to use the air conditioner by turning it on for 1 hour, then turning it off, and then turning it back on, or setting the temperature relatively high and leaving it on all night? Does the electricity industry participate in consulting on energy-saving air conditioners? How can we distinguish which type is good?

The discussion on electricity prices on the morning of May 16 organized by Thanh Nien Newspaper received hundreds of questions from readers.

Mr. Bui Trung Kien - Deputy General Director of Ho Chi Minh City Electricity Corporation : Ho Chi Minh City Electricity Corporation also has experience in promoting electricity saving. We do not recommend turning off electrical equipment but want customers to use electricity wisely. For example, set the air conditioner temperature to be about 5 degrees different from the ambient temperature to avoid heat shock when going out. When the outside temperature is too hot and the air conditioner is set at a low temperature, many people are susceptible to catching a cold. Meanwhile, many people share that turning on the air conditioner at a moderate temperature and at the same time using a fan to spread the cold air both ensures health and saves electricity.

There is no exact figure for the percentage of electricity reduction because it depends on the habits and the number of devices used in each household. We truly estimate that if we apply the electricity saving measures advised by EVN, the amount of electricity consumed will be reduced by at least 30%. Applying more smart devices will save more electricity consumption.

Mr. Bui Trung Kien - EVN HCMC shares about how to use electricity economically

An Dong market traders complain about having to pay high electricity prices for many years, what does Ho Chi Minh City Electricity say?

Mr. Kien recommends: Do not use the air conditioner by turning it on for 1 hour and then turning it off because it will reduce the life of the air conditioner. You should choose the optimal mode of 26 degrees Celsius, which saves electricity, ensures health, and ensures the life of the air conditioner. The electricity industry only advises customers to use electricity economically. As for devices sold on the market, consumers should choose products from reputable manufacturers and sellers with energy-saving labels. These devices have been managed and inspected by market management, so they are trustworthy.

Mr. Ha Dang Son - Director of the Center for Energy Research and Green Development: In principle, we will use the air conditioner with a difference of 7 - 10 degrees Celsius with the outside temperature. For example, normally it is opened at 26 degrees Celsius but when it heats up to 37 - 38 degrees Celsius, the temperature should be set higher to 29 - 30 degrees Celsius to avoid thermal shock. When set at 30 degrees Celsius, the air conditioner will automatically turn off, but when set at 26 degrees Celsius, the air conditioner will run continuously 24/24 hours, consuming a lot of electricity.

The review and labeling of energy efficiency is managed by the Ministry of Industry and Trade . The standards for labeling processes… also have the participation of the Ministry of Science and Technology, ensuring transparency and international standards.

Mr. Nguyen Quoc Dung - Head of EVN Group's Business Department: Air conditioners account for a very large proportion of electricity consumption, from 40 - 75% of electricity used in households. This is an issue that needs attention. If we reduce the air conditioner temperature by 1 degree Celsius, energy consumption will increase by 1 - 3%. The air conditioner mode should be set at 26 degrees Celsius or higher and ensure that it does not exceed 10 degrees Celsius compared to the outside temperature. If the difference is over 10 degrees Celsius, the air conditioner's efficiency will be low and its lifespan will be reduced.
