Interview with Multi V 5 Developers Yongcheol Sa, Seokho Choi and Siyoung Oh
Q1. Please give us an introduction to the Air Solution R&D Lab
We conduct advanced research at the Air Solution Research Center to develop new technology and elevate our competitive edge in system air conditioning to a global level. System air conditioning is a comprehensive term that refers to a wide range of heating, cooling and ventilation systems tailored to fit a new building or renovation development by connecting outdoor and indoor HVAC units together. Rapidly growing system air conditioners are economical, efficient and reduce initial investment and operating costs by allowing system conversion from cooling to heating mode.
Q2. I heard that you are combining biomimicry technology to harness both sound emission and energy consumption. Tell us what kind of technology this entails.
The current system air conditioning market is trending towards increasing the maximum capacity of single unit air conditioners in order to reduce initial costs and simplify the installation process. This trend makes it necessary to increase the air volume of outdoor units to improve maximize system capacity without increasing the size of the products. However, when the air volume of outdoor units increases, so does the sound emission and energy consumption of the axial-flow fan. Therefore, development of a low-noise, high-efficiency axial-flow fan was needed.
Q3. A 2dB sound reduction and 10% efficiency increase is impressive. Was it difficult to develop this technology with LG Electronics and Seoul National University joint research team?
Seokho Choi The most difficult part of the project was applying the biomimicry form to the actual fan. In the initial stages of development, the team at Seoul National University attached small beads and foam to fans in order to replicate the form of humps on humpback whales fins. But the beads and foam began to fall off the fan as the fan rotated at high speeds.
Q4. What sort of product is the ‘Multi V 5’ that we have been hearing so much about?
Q5. What efforts are you making to gain insight for the sake of the consumer?
Q6. What’s the most important thing you have gotten out of this development project experience?
Seokho Choi Bringing a new product from R&D to mass production is a difficult process. The most important thing in facing these difficulties and resolving these problems is a positive mind. By keeping a positive mind and maximizing the advantages of a technology or product, you can overcome obstacles and get positive results.
