“エアコンのギモン”ズバリ解決　冷房？除湿？専門家伝授快適＆お得な温度【スーパーJチャンネル】(2026年7月16日)

On the 16th, we'll get straight to the answers to your "air conditioner questions," which have become increasingly indispensable. Ultimately, what's the ideal temperature setting? ■ Straight to the Answers to Your "Air Conditioner Questions" Person in their 80s "I hadn't used the air conditioner for a long time. I couldn't tell if it was hot or cold. I lost my sense of temperature as I got older. I felt strange for about two days after eating, I felt dizzy, and I didn't understand why. I went to the doctor and found out I had a 38°C fever." "(Q. Was that heatstroke?) I think so." The woman in her 80s said she had previously suffered from heatstroke because she didn't use air conditioning. Person in their 80s "I had my throat checked and thought it was just a cold. But I felt strange again the next day, so I didn't use the air conditioner. That's why air conditioning is absolutely essential." "(Q. Now?) I leave it on 24 hours a day." "(Q. What changes have you noticed?) I'm feeling better." Air conditioning has now become a lifeline in the summer. A person in their 60s: "It's just unbelievable. I can't live without air conditioning." A person in their 70s: "I turn on the air conditioner first thing when I get home." ■Cooling? Dehumidifying? What's best for the summer heat? On the 16th, 145 locations nationwide recorded extremely hot days. Tokyo also experienced extremely hot days. Here's what people on the street are saying about how to use air conditioners to cope with this heat… Man: "Almost exclusively cooling. I don't really know the difference." The remote control has both cooling and dehumidifying. Which do you use at this time of year? Person in their 60s: "Air conditioning. I have a dog, so I leave it on all day." Person in their 80s: "Mostly dehumidification. When the humidity drops, it naturally feels cooler, so I think it's better to lower the humidity." Person in their 40s: "Dehumidification. I think dehumidification suits my body better." Person in their 70s: "I have a thermometer and a hygrometer. When the humidity is high, I use dehumidification, and when it's not so bad, I use air conditioning." With temperatures already approaching 40°C this year, how should we use them best? We spoke to Fuko Fukuda, a Panasonic Air Meister and air conditioning specialist. Fuko Fukuda, Panasonic Air Meister: "On hot days like today, don't hesitate to use air conditioning. Air conditioning is designed to lower the room temperature, so I think it's fine to turn it on without hesitation when the room temperature exceeds approximately 28°C." While dehumidification also lowers the room temperature, air conditioning is said to be optimal for the recent summer heat. ■Expert Advice: Comfortable & Economical Temperatures An 80-year-old woman's question was… 80-year-old woman "(Q. What do you do to improve the effectiveness of your air conditioner?) I use a circulating fan. Where should I place the circulating fan to make the air conditioner work efficiently?" Panasonic Air Meister, Fuko Fukuda "Cold air sinks. If you point the back of the circulating fan towards the air conditioner, and position it so that the cool air coming from the air conditioner is directed towards you, you can effectively circulate the cool air that is far away around you." A couple living in Kumagaya City, Saitama Prefecture, a city known for its heat, which the program interviewed, were also coping with the heat using this method. 70-year-old couple "The cool air is coming this way, and it's cool." It's said that using an air conditioner and a circulating fan together makes it more comfortable, but what temperature should you set it to in the first place? Person in their 70s: "I only use the air conditioner." "(Q. What temperature do you set it to?) 26°C. Because the afternoon sun shines into the living room." Person in their 60s: "I think 26°C is the best." Many people say they set their air conditioners to 26°C because of the extreme heat, but there are also comments like this... A person in their 60s: "I have it set to 26°C. I'd like to know the most economical way to use my air conditioner." Fuko Fukuda, Panasonic Air Meister: "The most commonly used temperature range is 26°C, but raising the cooling setting by 1°C can save 10 to 13% energy. For example, if you set the temperature to 27°C instead of 26°C, the room temperature will indeed rise by 1°C, but if you increase the fan speed and feel the airflow, roughly the same as a medium-speed fan, the perceived temperature will drop by 1°C. Therefore, before lowering the temperature setting, increase the fan speed." It is said that even if you raise the air conditioner's temperature setting, you can lower the perceived temperature by increasing the airflow. Fuko Fukuda, Panasonic Air Meister: "Air conditioners use about 80-90% of their electricity when the compressor, the heart of the unit, is running in the outdoor unit. That's where the electricity costs a...
