As the indigenous people of the Arctic Circle, the Inuit are known for their special construction techniques. They live in igloos made of ice, so why aren't they afraid of the cold in the face of the harsh extreme cold? Doesn't igloo fire cause the ice to melt? Let's uncover the science behind this mysterious igloo.
###1. The structure of the igloo###
First, let's take a look at the structure of an igloo. The Inuit built the entire igloo structure out of slender blocks of ice, called "snow bricks". These snow bricks are closely packed to form a solid façade and roof, while also having a certain density. This layered structure prevents cold air from the outside from penetrating into the house and forming an insulating layer.
###2. Ice heat retention###
Ice may seem like the opposite of keeping warm, but in reality, the inside of an igloo is much warmer than the outside. This is because ice has a high density and heat capacity, and it can absorb and release a lot of heat. When the outside temperature is low, the heat inside the igloo will slowly dissipate to the outside through conduction, forming a relatively stable warm space.
###3.Isolation of the igloo from the outside world###
The ice cubes in the igloo act as a barrier to heat insulation, effectively blocking the inflow of cold air from the outside. Compared to the walls of ordinary houses, ice cubes have lower thermal conductivity, reducing the speed at which heat is transferred. At the same time, there is a curtain at the entrance of the igloo to further isolate the temperature difference between indoor and outdoor and maintain a warm indoor environment.
###4.Rational use of ignition sources###
The igloo does not ignite the fire directly on the ice, but on a stony or dirt ground. This isolates the fire from the ice and avoids the problem of ice melting. The roof of the igloo also has a special design that expels smoke and exhaust gases to ensure indoor air circulation.
###5.Indoor climate regulation###
The Inuit used candles as their primary lighting and heating tool in igloos. Candle burning produces a small amount of heat that can provide some warmth. In addition, the Inuit are experienced in how to control the temperature coordination between indoor and outdoor by opening or closing entrances and exits. In extremely cold environments, they are very good at using natural resources and the temperature difference between inside and outside to regulate the climate.
##结语: ##
The Inuit live in igloos and are not afraid of the cold in the face of the bitter cold. The structure of the igloo and the heat retention of the ice make it possible to keep the interior relatively warm in comfort. The rational use of fire sources and the regulation of the indoor climate are also the keys to their success in coping with extreme cold environments. The Inuit's wisdom and in-depth knowledge of nature allow them to enjoy a warm and comfortable life in the snow and ice.
