Chapter 279: Sudden blizzard

Early in the morning, when Chen Xin finished washing and took the elevator to the observation room on the upper floor of the refuge, the two brothers Han Ping and Han Ze were cooking a pot of thick hot soup around the stove, and the aroma of food was floating in the air , The heat from the stove also slightly dissipated the cold in the house.
"Good morning, Han Ping, Han Ze, did you sleep coldly last night?" Chen Xin felt the temperature in the room and asked the Han brothers who were wearing temporary exoskeleton protective suits.
"Mr. Chen." When Han Ping saw Chen Xin coming in, he hurriedly pulled his younger brother next to him, stood up and greeted Chen Xin: "It's okay, but I can stand it in the room at night. The heating of the clothes is turned on, otherwise you can't stand it."
Hearing what Han Ping said, Chen Xin gestured to the two of them to sit down and then glanced at the observation window that had been blocked by the glass. He shook his head and said helplessly, "If you can stand it, you can go down at night. Go to sleep. It's too cold, and no one will come here in this bad weather."
However, Han Ping still shook his head and said: "The more the weather is like this, the more you must be vigilant. People who can still come out of this kind of weather are either vicious or unable to survive. They are all dangerous and must be vigilant."
Faced with Han Ping's attitude, Chen Xin couldn't say anything about him, but complained in his heart that the snowstorm came without warning.
Not long after Li Tou and Ding Ning came before, a blizzard suddenly blew that night, and the temperature dropped sharply again. From the originally tolerable minus 30 degrees, it suddenly fell below minus 70 degrees. And accompanied by strong winds that can blow over ordinary cars.
The arrival of the blizzard had no signs, as if it had blown up in an instant, and it had swept everything before people could react.
Chen Xin can understand the emergence of this kind of weather. After losing the protection of vegetation and the regulation of atmospheric circulation, the weather system on the entire surface of the earth has completely collapsed, and the squally winds have lost their barriers and become more violent. The emergence of extreme weather is only the weather. One of the effects of system crashes.
The cold wave in the past winter will cause a large-scale cooling in Yan Country. Now that the weather system has collapsed, the cold brought by this blizzard will also affect many places, and what is different from the past is the temperature once Once it has fallen, it will be difficult to recover.
Because the sun's light, the main source of heat on the blue star's surface, has been blocked by dust, even if the blizzard dissipates, it is still very difficult for the temperature to rise.
At this time, strong winds of over twelve levels were whizzing past the refuge, and numerous goose feathers were being rolled up. If there is still the sun, you will be able to see the vastness of the sky and the earth.
However, the snowflakes floating in the sky at this time are not ice crystals, but carbon dioxide snow formed by the liquefaction of carbon dioxide in the air at low temperatures, which is commonly referred to as dry ice.
The extreme low temperature has obviously broken the limit of most buildings to withstand the cold, and even the upgraded refuge here in Chen Xin can't stand it, so Chen Xin had to turn on the heating system in the refuge to the maximum power. It can ensure the indoor temperature and the survival of plants in the greenhouse.
This also made Chen Xin aware of a problem with the ground source heat pump as a heating device. It is affected by the ground temperature and has a limit in temperature rise.

Although his refuge is deep underground, there is no problem at present, but if the blizzard continues, the temperature will not rise for a long time, and the deep stratum may have no effect, but the shallow stratum will definitely lower the temperature.
This will undoubtedly cause the ground source heat pump equipment that mainly depends on the temperature of the shallow strata to obtain heat to be affected, reducing the heating effect.
So if the temperature continues to drop, Chen Xin must consider using other heating methods in the shelter.
And now, the temperature in the upper observation room on the surface has dropped to more than 20 degrees below zero. This is the result of Han Ping and Han Ze having been on the stove in the room.
It was precisely because of such low temperature that Chen Xin wanted to let the two brothers go to the lower level of the refuge. It was too cold above, and he was a little worried that the two brothers could not bear it.
But Han Ping insisted on staying on it, and kept doing night watch work with his brother.
Chen Xin, who couldn’t persuade him, could only allow Han Ping to take his brother to the upper level of the refuge. However, for safety reasons, Chen Xin still prepared a stove and two sets of emergency protective clothing for them to prevent them from being there. Frostbite and frostbite in low temperature environment.
With the protective clothing, the two brothers Han Ping and Han Ze actually feel that the temperature is still acceptable. After all, it is equivalent to being wrapped in an electric blanket. In addition, there is a stove to cook hot food at any time to supplement body heat, except for the night watch. It was a bit difficult, but it was actually okay.
However, Han Ping still asked Chen Xin with some worry: "Mr. Chen, our conditions are so good here and it's so cold, isn't it colder in other places?"
"Other places? If cold protection and warmth are not well done, I am afraid it is not just a colder problem, it will freeze people to death." When Han Ping asked this question, Chen Xin inevitably shook his head.
The temperature of minus 40 degrees Celsius can still be encountered in the north, but the temperature of minus 70 degrees is very extreme.
In this temperature ~EbookFREE.me~ the scene of freezing a helicopter flying in the sky directly in the movie "The Day After Tomorrow" will really appear.
The temperature of the polar regions makes it difficult for even fire to rise. Even if there are buildings that can withstand the cold wind, if there is no heat source, the temperature drop is enough to freeze all life.
The urban area relies on coal-fired boilers for heating. It should still work normally in this kind of weather. However, most of the refuges in the urban area are not of the type that goes deep underground, and most of the cold-proof insulation is before the disaster It was temporarily renovated for three months, which inevitably made Chen Xin very worried about the situation in the city.
But in this environment, even Chen Xin didn't dare to go out. The blizzard outside was enough to put any vehicle in a desperate situation. Even his modified tracked RV could not be guaranteed in this environment.
Perhaps only the heavy-duty truck in "Wandering Earth" may be able to cope with such harsh weather?
Chen Xin thought so in his heart, and the attitude that had become comfortable because of the better living conditions became tense again and felt the crisis of survival.
Although Chen Xin himself can live without any worries, it is not that he really has no survival crisis.
