On the morning of April 1, the first day of implementing the Prime Minister’s directive on social distancing from 0:00 on April 1 nationwide, loudspeakers in communes and wards in Hanoi continuously broadcast and propagate to People understand and strictly follow the directives to ensure the prevention of the Covid-19 epidemic.
Air conditioners help cool (or heat) and regulate the humidity in the room. In tropical countries like Vietnam, during hot summers, indoor air conditioning usage time is often quite long, which means electricity bills skyrocket. Therefore, choosing a product that saves electricity while still ensuring cooling efficiency is a priority for many people.
Among them, wall-mounted air conditioners are a popular product with Vietnamese families because they are suitable for our country’s weather conditions, the air-conditioned room is quiet, and the investment and operating costs are reasonable and relatively affordable. Save electricity compared to other models.
Below are some characteristics that demonstrate the energy saving ability of an air conditioner:
Number of stars on the energy sticker
According to regulations of the Ministry of Industry and Trade, all air conditioners circulating in the Vietnamese market must have energy labels. This is essentially a sticker confirming whether the product’s performance and electricity consumption meet or exceed the energy efficiency standards set by the Ministry of Industry and Trade at the time of testing. The energy label notes from 1-5 stars along with parameters related to the product’s origin, evaluation standards, and power consumption performance. The fewer stars a product has labeled, the higher its power consumption level. The 5-star label is the most energy-efficient level.
The 5-star label is the most energy-efficient level.
CSPF energy performance index
CSPF (abbreviation for Cooling Seasonal Performance Factor) means whole-season cooling performance index. The CSPF index also indicates that for 1 kWh of electricity consumed by the air conditioner, how much cold air will be received from the conditioned space, but taking into account seasonal temperature changes within a year.
The higher the CSPF index, the more efficiently the machine operates and saves electricity.
Daikin’s FTKM Inverter series has a CSPF index of 7.4, which is high on the market today, so it is very energy efficient.
Power saving technologies
If you’re shy about numbers, you can look at the power-saving technologies used to decide which product to buy.
Inverter technology: Inverter air conditioners use inverter technology compressors so that when the air conditioner is turned on, the motor will start and operate at maximum capacity, to quickly reach the set temperature, then reduce it. load to maintain the set temperature, providing constant comfort in the room. Meanwhile, conventional non-inverter air conditioners will turn off the motor when they reach the set temperature, and will restart from the beginning when they want to continue cooling. Because you don’t have to turn the engine on and off constantly, inverter air conditioners help save energy. Inverter air conditioners are suitable for spaces where the machine is used for a long time, while non-inverter air conditioners are suitable for spaces where the machine is used for a short time. In addition to savings, inverter lines operate quieter, maintain a more stable temperature, helping users feel more comfortable. In particular, Daikin, the leading brand in the air conditioner industry, also uses an exclusive Swing compressor with a rotating mechanism to circulate the refrigerant. This gentle circular motion significantly reduces vibration friction, helping to reduce loss of refrigerant (R32) during operation, pushing usage cost savings to the maximum.
Smart eye: is a technology that operates based on the mechanism of using infrared rays as a sensor, detecting the movement and position of the user in the room to adjust the appropriate wind direction and temperature, contributing to saving energy. save energy consumption. If there is no movement in the room for 20 minutes, the machine automatically increases by 2 degrees Celsius compared to the set temperature. On the contrary, if motion is detected, the sensor will bring the machine to operate at the initially set temperature level. Because of its ability to accurately detect position, the machine does not blow air directly at the user, helping the user feel more comfortable.
ECO technology has long been applied to many electrical products such as rice cookers, refrigerators, air conditioners… helping the products operate with lower power consumption than usual. In Daikin air conditioners, the ECONO feature helps the air conditioner reduce power consumption to a maximum level, save electricity but still ensure cooling or heating capabilities as well as comfort during use.
The air conditioner has smart eye technology that will automatically increase 2 degrees Celsius above the set temperature if no movement is detected in the room for 20 minutes, helping to save energy.
Smart air conditioners can connect to your home’s Wifi network, allowing you to control the system from anywhere with your smartphone or tablet. The smart system makes it easy to customize your cooling schedule to save money. A wifi-connected smart thermostat can contribute to energy savings when used for heating or cooling.
