Do you know the history of "Inventor's Day" in Thailand?
The National Research Council of Thailand informed His Majesty King Bhumibol Adulyadej the Great on 2 February 1993 that his invention "Chaipattana Low Speed Surface Aerator" had been granted patents, earning him the titles "Father of Thai Invention" and "Father of World Invention". To honor him, the 2nd of February is designated "Inventor's Day".
So what’s the day’s significance for RISC?
RISC is committed to embracing new ideas and developing innovations that improve quality of life, particularly in daily life. We spend over 90% of our time indoors, so the most essential breakthroughs include those for ventilation. We all need to breathe and indoor ventilation can enhance indoor air quality:
The "Ventilation Door" will improve ventilation and help release accumulated moisture, which can cause fungi and bacteria in hidden areas such as behind wallpaper. It also decreases volatile organic compounds (VOCs) from paint, furnishings, and furniture. The higher the temperature, the more VOCs are released, direct impacting health if they collect in our bodies over time, causing skin and eye irritation as well as increasing the risk of cancer.
RISC has also created "DOAS A/C" to replace current air conditioning. Rather than circulating air within the room, DOAS A/C can bring fresh outdoor air in through a filter that takes out particles as small as PM0.3. Less carbon dioxide builds up in the room, reducing health risks.
Inhaling high levels of carbon dioxide speeds up breathing due to elevated blood pressure and a faster heart and pulse. In the long term it can cause drowsiness, headaches, dizziness, lightheadedness, disorientation, hearing loss, and vision problems. We might also experience perspiration, tremors, nausea, and diarrhea from expanding blood vessels. Some people may develop panic episodes. If they inhale deeply enough, they may lose consciousness or die.
Cold-water pipes for DOAS A/C also feature an innovative "Chiller Façade" to reduce the temperature of air coming into the building, cutting energy consumption. As we can see, innovative design for good ventilation must consider both indoor and outdoor systems to improve residential quality of life and reduce energy consumption systematically and sustainably.
