It turns out that if you go out for 30 minutes and the outside temperature is 3 degrees or higher, it is advantageous to drive "turn off frequently"! -Winter air conditioner power saving technique taught by Panasonic-Various price increases such as electricity bills, 70% of people answered that they "feel a burden"

Panasonic Co., Ltd. is investigating the actual power saving of air conditioners in winter, and is unique about the difference in power consumption between "keeping on" and "frequently turning off" when going out for 30 minutes while heating the air conditioner in winter. It was verified based on the experimental results. In addition, Panasonic's Air Meister Fuko Fukuda will introduce "5 tips to save electricity bills for air conditioners in winter". Panasonic surveyed 550 men and women in their 20s and 60s about this year's price increases and winter air conditioner power saving. Since September 2021, 70% of the questions asked "Do you feel the burden of" price increases "for coffee, flour, margarine, Japanese and Western confectionery, electricity bills, etc. that continue in real life?" 70.9%) answered "yes", indicating that various price increases are hitting home wallets directly . In a survey of the actual situation of power saving in winter air conditioners, 52.7% answered "yes" to the question "Are you conscious of power saving in winter air conditioners?", And it was found that the majority are conscious of power saving. Did. The things that are actually practiced with power saving in mind are "lower the set temperature" (70.7%), "wear heavy clothes" (46.9%), and "be careful about how often the switch is turned on and off". (32.8%) is the TOP3 result. A more detailed survey of the "frequency of turning the switch on and off", which is practiced by many people as a power saving method for air conditioners in winter, shows that "keeping on" is 56%, but "frequently turns it off". It turned out that the percentage of "sects" was 44%, and the percentage of "sects left on" was slightly higher. When you go out for 30 minutes while the air conditioner is heating, which is better, "keep it on" or "turn it off frequently"? Following Panasonic's original survey on air-conditioning savings in the summer in July 2021, "It is better to turn off the outings on midsummer days frequently! 67% less electricity bills a month than leaving the car on", followed by winter. Fuko Fukuda, Panasonic Air Meister, will explain how to save electricity in the air conditioner. (Https://prtimes.jp/main/html/rd/p/000000494.000024101.html) It is said that it may be more advantageous to keep the air conditioner on than to turn it off frequently. increase. The air conditioner requires a lot of power when the operation is turned on when the temperature difference between the inside and outside of the room is large, but once the temperature inside the room becomes appropriate, it can be kept with a small amount of power consumption. Therefore, if the operation is turned off and the room temperature approaches the outside temperature, it is possible to perform "strong operation" that consumes a lot of power when it is turned on again. As a result, it may consume less power if left on. This time, we will compare and verify the electricity bills for "keep on" and "turn off frequently" for the use of heating in winter. Using Panasonic's original algorithm, we conducted a simulation focusing on the fact that the power consumption of driving when returning home differs depending on the outside temperature conditions even when the same outing time is used. As a result, when using heating, although it depends on the environment such as the heat insulation of the house and the indoor heat load , in the case of severe cold such as when the outside temperature is less than 3 ° C, the room temperature tends to drop significantly and many to return to the set temperature. Since power is required, "keeping on" driving is advantageous. On the other hand, if the temperature is 3 ° C or higher, the room temperature does not drop that much, so it was found that "frequently turning off" operation leads to savings in electricity bills. For example, in the case of Tokyo, the average temperature in January, which was the lowest last winter, was 5.4 ° C, so basically it seems that "turn off diligently" is a good deal. Panasonic's "Aeolia" is equipped with a "keep-on judgment function" that lets you know which is better, leave-on or run-off. Based on the time you go out, the heat insulation performance of the house, the weather forecast, etc. predict. It is convenient for a little outing. You can easily judge by simply entering the outing time (15 minutes to a maximum of 3 hours can be set) in the app. * According to Panasonic research. Simulation results with an indoor temperature of 24 ° C, a heating temperature setting of 24 ° C, and an electricity bill of 27 yen / kWh * The actual electricity bill will vary depending on usage conditions such as the heat insulation performance of the house and the installation environment of the air conditioner. If dust collects on the filter of the indoor unit, it will become clogged and the amount of air taken in will decrease. As a result, air conditioners use extra power in an attempt to secure the necessary air. According to Panasonic's experiments, if you do not actually clean for one year, you will waste about 25% of your electricity bill annually compared to cleaning. In this case, cleaning the filter can save about 10,000 yen * or more per year in electricity bills. From this result, let's clean the filter diligently. * Panasonic product "CS-F401D2" is used. Experiment with electricity bill of 27 yen / kWh Even at the same set temperature, the sensible temperature rises as the humidity rises. In winter, raising the humidity not only prevents dryness, but also makes you feel warm, so try to humidify it. In addition, even changing the set temperature of the air conditioner by 1 ° C will save money. According to the Ministry of the Environment, if you raise the temperature by 1 ° C during summer cooling, the power consumption will be reduced by about 13%, and if you lower it by 1 ° C during winter heating, the power consumption will be reduced by about 10%. Panasonic's "Aeolia" launched the new "Aeolia" LX series with a humidifying function in November. The LX series is the first in the industry. * The outdoor unit is equipped with a "polymer sorbent" as a material that absorbs moisture. "Polymer sorbent" has high hygroscopicity, and by taking in the moisture of the outside air and sending it to the room during heating, it quickly humidifies the room without the hassle of water supply and prevents drying, which is a problem in heating. * As of September 21, 2021. In domestic home air conditioners. The heat in the room is the one that goes in and out most through the windows. Use a heat insulating sheet or a heat insulating curtain. If the curtain is a type that reaches the floor, it is possible to suppress the cold air that enters through the gap in winter. It's also a good idea to use two curtains or install an inner window to create a layer of air between the window and the room. Warm air moves upwards, so it is necessary to circulate the indoor air with a circulator. In winter, install it on the diagonal line of the air conditioner, and if you send the wind upward, the warm air accumulated near the ceiling will easily circulate in the room. When the wind hits a person, the sensible temperature drops and it feels cold, so adjust the angle of the air. It doesn't need to be cleaned as often as the filter, but the outdoor unit is also unexpectedly dirty. If dust and other debris accumulates, the efficiency of heat exchange will decrease, which may lead to increased power consumption, so check it especially on windy days or after a typhoon has passed.
