As environmental problems such as global warming become more serious, achieving carbon neutrality (net zero greenhouse gas emissions) has become an important global issue. With the market also demanding products with lower power consumption, what kind of performance is required for the fans built into various devices and products?
With the aim of achieving carbon neutrality by 2050, society as a whole is actively working to reduce the environmental impact. Reducing the power consumption of products is one of the important factors in reducing the environmental impact. Reducing the power consumption of fans also leads to reducing the power consumption of the entire device. For this reason, there is a demand for fans that consume less power than conventional ones.
There are two types of fans: "AC Cooling Fan" that run on alternating current (AC) power, and "DC Cooling Fan" that run on direct current (DC) power. DC Cooling Fan are driven by efficient DC motors, which means they consume less power and have a longer lifespan than AC Cooling Fan. Using DC Cooling Fan is an effective way to reduce power consumption, but it requires a separate DC power supply. Therefore, if you are using an AC-powered fan, it may be difficult to replace it with DC Cooling Fan. In such cases, ACDC Fan is recommended.
Company C manufactures and sells refrigerated showcases and other products for various stores.
Mr. A, the development manager, was checking customer requirements for the development of a new refrigerated showcase.
Because refrigerated display cases are in constant operation all year round, major supermarket customers requested that "electricity bills are becoming a burden. In addition, we would like products that are environmentally conscious and consume as little power as possible."
Although we wanted to consider DC Cooling Fan that consumes less power and has a longer lifespan than AC Cooling Fan we had been using, refrigerated showcases are basically powered by AC power, and we had a hard time finding a fan that met Mr. A's requirements for cooling performance and low power consumption.
Mr. A was troubled and consulted with SANYO DENKI CO., LTD. SANYO DENKI CO., LTD. whose sales representative suggested ACDC Fan, which offers the excellent performance of DC Cooling Fan with an AC power source.
We immediately ordered samples and evaluated them, and found that while the cooling performance was adequate, the power consumption was reduced to about one-fourth compared to AC Cooling Fan that had been used up until now. This will make a significant contribution to overall energy savings when multiple refrigerated showcases are used.
Mr. A soon decided to adopt ACDC Fan and successfully developed a new refrigerated showcase that achieved energy savings that met his customer's needs.
*The price is based on 24-hour use per day.
Calculated based on commercial electricity (according to our research as of April 2023, 1 kWh = 22.68 yen including tax).
The actual price will vary depending on the power company and monthly power consumption.
This time, we introduced ACDC Fan, which help reduce the power consumption of equipment.
ACDC Fan can be used with AC power and consume low power. In addition, they have a long expected life and reduce maintenance efforts.
