So come into wild environment, the mountain-climbing of arduous even High aititude on foot will soon exhaust their strength, beaten
The heat that body produces can also be reduced, and will make one to be easier to feel cold.
In order to establish the temperature grade of sleeping bag, the sleeping bag prototype before commodity production will do outdoor test, and tester is past
Toward being the people often to live outdoors, such as soldier, guide etc. of climbing the mountain, they need to test several weeks in external environment out of office,
Manufacturer is provided on sleeping bag comfort temperature and the opinion of limiting temperature.
For sleeping bag production firm, test sleeping bag needs temperature wind speed, humidity, wind speed, the condition such as wear the clothes, and
And be difficult to go to face various natural environment and climate situations as alpinist, general test can only be based under ecotopia
Certain temperature and humidity, but the result tested and actual use situation are far from each other.In order to make test result be more nearly very
Real use environment, each brand establish climatizer one after another, and the physics such as temperature, humidity, wind speed are controlled in artificial environment
Condition, and test sleeping bag under corresponding weather, it follows that the temperature scale coefficient of proper true service condition.With section
The progress of skill, computer and various detection means are constantly progressive and perfect, and infra-red thermal imaging system also begins to apply ability sleeping bag
In test, heat dispersal situations of the human body in sleeping bag can clearly be judged according to infrared thermal imaging, red area represents to give out
The corresponding blue region of heat ratio come is more, and sleeping bag design can also thoroughly do away with test result and be correspondingly improved.
