Story of Ondol - Chilbulsa Ajabang

 There is a temple called Chilbulsa Temple at the foot of Jirisan Mountain in Jeolla-do. The legend that King Kim Su-ro's seven princes are sacred is a young place, and it is said to be a temple in Jirisan Mountain, well-known for its title as the best sailor in the East who produced numerous Zen temples such as Seosan. The Azabang in Chilbulsa Temple has a unique style that is recorded in the World Architecture Dictionary. However, what is famous about Ajabang is the legend about ondol, where the warmth does not go away for 49 days or winter once the fire is set. This Azabang has never been renovated since its construction, and it is said that during the reign of King Hyogong (897-911), Buddhist Monk Damgong built a gudeul in the shape of Aja in Byeokandang, a good room. In the early days, it was warm for about 100 days once it was on fire. This ajabang has a double ondol structure, and the high point on the four corners of the room and the front and rear edges is a seat, and the low cross-shaped area is a place to relax the legs while sitting. This Azabang is famous and known to the Tang Dynasty in China, and is also included in the World Architecture Dictionary published by the World Architecture Association in 1979 due to its excellent scientific nature of the room structure. If you block the furnace once every 100 years and clean it with water, the fire will be easily set without any side effects, and the warmth has been maintained from the high above the ark for a long time, and there are countless high monks who have gained through the capital in this room. The Azabang of Chilbulsa Temple has been around for as long as the story of the founding of Chilbulsa Temple, and unfortunately, the Azabang now is not the Azabang a thousand years ago. It was burned down by fire around 1800, and during the operation to subdue communist guerrillas in 1948, military units burned it down, leaving only ondol in the Azabang. After that, the current building was restored in 1982 with the efforts of Buddhist monk Tonggwang, and an official from Ondol Human Cultural Heritage, who was in charge of ondol repair at the time, said, "The principle of Ajabang was unknown, so it was placed in a general form." It's another article about Ajabang. There is a legend that once the fire was set in Chilbulam Hermitage, Banyabong Peak of Jirisan Mountain, the warm energy lasted 49 days. This Azabang was destroyed during the Korean War and restored in 82. This room is coated with high-quality red clay on top of the farts, and there is a 15-20cm auditorium resolution on the ondol feet, forming a thermal layer. According to legend, the restored Azabang does not last until 49 days, but it is said to last about a week in spring and autumn.Professor Min Man-ki (Mechanical Engineering) of Korea University explained that [the reason why the warmth lasts for a long time after setting a fire is because of the unique structure of the ondol and the nature of the stone placed on the ondol]. However, he added that [it is a scientifically difficult phenomenon that the warmth lasts for more than a week]. Unlike Western style, which uses air convection, ondol maintains warmth by radiant heating that directly transfers heat. The core of the ondol is in [Whale]. A whale is a path through which smoke passes through the empty space between the stones that make up the farts. The furnace is deep and the earthenware is shallow, so it looks like a whale when viewed from the side. When a fire is set in a fireplace, hot air circulates in the whale and delivers heat to the winding ground. The stones used in Gudeuljang determine warmth and health. All of our unique ondols use mica. Unmo is heated to 400 to 500 degrees when the firearm touches, and it can contain heat for a long time due to its low thermal conductivity. Since mica is also an alkaline stone with a lot of minerals such as magnesium oxide and calcium, far-infrared rays are generated when heat is applied. Choi Ryong, director of Ssangyong Cement Industrial's Central Research Institute, said, "This is the kind of goal used in Finnish saunas," adding, "It is amazing how I chose Dol when I couldn't know what far infrared rays were." In addition, a hill-shaped jump installed to allow flames to be easily sucked out of the furnace and a dog's seat dug parallel to the chimney to drain smoke easily are structures made with accurate knowledge of the flow of air. " Even in winter, it takes about three days to catch a fire, so it is the ultimate heat efficiency.
