For humans, although the environment of tens of degrees below zero is indeed a forbidden zone of life that is completely unsuitable for human survival, even in the polar regions where the environment is the worst, humans have also built permanent polar scientific research stations. Moreover, the scientific research stations are not buried deep underground, but are directly placed on the surface.

The low temperature of tens of degrees below zero is indeed a desperate situation of death, but with the current technology of mankind, it is still no problem to build a warm and comfortable scientific research station in this environment.

Taking the scientific research station built by Yanguo in the polar region as an example, the container room is sprayed with a 120mm thick polyurethane insulation layer and then decorated with outfitted panels. It is both warm and beautiful, and can completely withstand the severe cold and low temperatures of tens of degrees below zero in the polar environment.

Of course, the scientific research station itself does not generate temperature. Even if the insulation is done well, heat exchange is still happening, so the scientific research station itself still has heating equipment.

But this is enough to prove that the existing technology of human beings really does not need to dig thousands of meters underground when facing severe cold and low temperatures.

With humans' existing scientific and technological strength, as long as the shelter is insulated and reliable heating equipment is equipped, it is enough to ensure that a shelter can be warm and comfortable in an environment of tens of degrees below zero.

However, reliable heating equipment is not so easy to guarantee in this era of the apocalypse.

Taking the polar scientific research station as an example, there are roughly two types of heating methods generally adopted, namely electric heating and fuel heating.

Since scientific research stations usually generate electricity 24 hours a day, larger scientific research stations generally use indoor electric heating for heating. This method is simple to install and maintain, and can control the temperature at will, clean and clean. However, sometimes most of the electricity is used in heating. When the temperature in the external environment is low, it is easy to cause excessive load on the generator, and improper use can also cause electrical fires.

Some scientific research stations use oil-fired boilers as the main heating equipment, similar to ordinary heating in the northern part of Yan Kingdom. This requires additional installation and maintenance of heating equipment, but it is not prone to electrical fires and other accidents, which can effectively reduce the load of the generator.

In addition, some small summer scientific research stations only have simple gas heating equipment. They use special gas heating indoors to burn liquefied gas or natural gas, but they need to pay attention to ventilation and keep an eye on the concentration of carbon monoxide in the air at any time to avoid carbon monoxide poisoning.

These three heating methods are mature and reliable heating methods. Although each has its own advantages and disadvantages, they are all qualified to maintain heating needs in the shelter.

According to Chen Xin's understanding, the three large shelters in the city use additional boilers for heating, but they do not burn fuel, but coal.

Yan's oil resource reserves are not particularly abundant, but coal resources are relatively sufficient. After all, Yan's oil reserves are ninth in the world, but coal reserves are third in the world.

Moreover, the oil is produced from crude oil, which cannot be burned directly. It also needs to be processed into gasoline, diesel, kerosene, etc. before it can be burned.

However, coal can be burned directly when dug out, so when it can ensure railway transportation, burning coal is undoubtedly more stable and reliable than burning oil.

Therefore, it is a very good choice to use boiler heating in large shelters. As for the additional maintenance work, the least valuable thing in the end of the world is manpower. There are tens of thousands of people living in a large shelter, so there is no need to worry about not being able to find anyone to work.

For a shelter that is not that large, there is no need to adopt this method. While the power supply can be guaranteed, they can use electric heating to keep heating, and there is no need to install a heating boiler.

Private shelters like Chen Xin and Mo Qingyan, installing an air conditioner that can be used to keep heating or preparing two electric heating stoves can basically meet the heating needs. Installing a boiler is purely for burning money and brain-brushing, and it is not practical.

However, this incident reminded Chen Xin that the heating system should be put on the agenda in the shelter upgrade plan.

Although I have prepared an electric stove and electric blanket for myself, isn’t it good to upgrade to make myself live more comfortable? Why do I have to wear cold clothes indoors and wear three quilts to sleep?

Chen Xin thought about this, and habitually took out his notebook, wrote and painted on paper, and considered the next upgrade plan for the shelter.

The notebook now states four items: power supply, lighting, food and medical care in the order Chen Xin recorded before. Chen Yu thought about it and added the heating project before lighting.

The power supply system must be the most preferred option for upgrading, because among the other four projects on the laptop, except for medical care, which is not a priority, the other three projects will increase the power consumption of the shelter. Therefore, upgrading the power supply system and increasing the power generation of the shelter is an inevitable thing to do.

Moreover, Chen Xin must also consider the fuel consumption caused by power generation. It is important to know that according to his current electricity consumption, the average gasoline used to generate electricity every day requires ten liters. As the electricity consumption increases, the consumption of oil will inevitably increase. Chen Xin must consider the supplement of gasoline and obtain a more lasting and efficient power generation method.

If it is normal, Chen Xin could consider the long-term and self-sustaining high-efficiency power generation method, which is the only way that he can hardly touch. However, for Chen Xin, who has a system, geothermal power generation and geomagnetic power generation, which are currently in the science fiction and laboratory research stages for humans, are all in his promising upgrade plans in the future.

Therefore, Chen Xin is not worried about how to obtain efficient and lasting power generation methods. He just keeps upgrading the shelter. As long as he keeps upgrading and has enough survival points, Chen Xin believes that even a black-tech power generation method such as antimatter reactor or artificial sun can be upgraded.

Although these science fiction-level technologies are too far away for Chen Xin and the survival points they need are astronomical, under the powerful power of the system, these are indeed things that can be expected.

Although the future is promising, it is too early to think about these things now. The most important thing now is to replant the vacant land in the greenhouse after harvesting vegetables and sow new vegetables, so that there will be enough harvest next month to find Mo Qingyan to change the materials needed for upgrading.

However, when she thought about exchanging supplies, Chen Xin felt that she should make a list first to see what supplies she needed now. This would be more targeted when looking for Mo Qingyan to exchange supplies, and she could prepare in advance so that she could save time.

You should know that even if Mo Qingyan has Uncle Ding’s relationship, it will take time to get the supplies.
