Doomsday Bunker Upgrade

For humans, although the environment of dozens of degrees below zero is indeed a forbidden area for human life, it is completely unsuitable for human survival, but even in the polar regions with the worst environment, humans have also built permanent polar scientific research stations, and scientific research The station is not buried deep underground, but placed directly on the surface.

The low temperature of dozens of degrees below zero is indeed a desperate situation of death, but with the current technology of human beings, it is not a problem to build a warm and comfortable scientific research station in this environment.

Taking the scientific research station built by Yan Guo in the polar regions as an example, the interior of the container house is sprayed with a 120mm-thick polyurethane insulation layer, and then decorated with outfitting boards, which is both warm and beautiful, and can fully withstand the severe cold and low temperature of minus tens of degrees below zero in the polar environment.

Of course, the scientific research station itself does not generate temperature. No matter how good the insulation is, heat exchange still occurs, so the scientific research station itself still has heating equipment.

But this is enough to prove that human's current technology really does not need to dig several kilometers deep in the face of severe cold and low temperature.

With the existing scientific and technological strength of human beings, as long as the shelter is built with thermal protection and reliable heating equipment, it is enough to ensure that a shelter can be warm and comfortable in an environment of dozens of degrees below zero.

But reliable heating equipment is not so easy to guarantee in this apocalyptic era.

Taking the polar scientific research station as an example, there are generally two heating methods generally used, electric heating and fuel heating.

Since scientific research stations usually generate electricity 24 hours a day, larger scientific research stations generally use indoor electric heaters for heating. This method is easy to install and maintain, and the temperature can be controlled at will. It is clean and clean, but sometimes most of the electricity in scientific research stations is used In terms of heating, when the external ambient temperature is low, it is easy to cause the generator to be overloaded, and improper use can easily lead to electrical fires.

Some scientific research stations use oil-fired boilers as the main heating equipment, which is similar to the ordinary heating in the northern part of the 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 generator load.

In addition, some small summer scientific research stations only have simple gas heating equipment. They use special gas heating indoors to burn canned liquefied gas or natural gas, but they need to pay attention to ventilation, and always pay attention to the concentration of carbon monoxide in the air to avoid poisoned by carbon monoxide.

These three heating methods are all mature and reliable heating methods. Although they have their own advantages and disadvantages, they can all meet the heating needs of the shelter.

According to Chen Xin's understanding, the three large shelters in the city all used the method of building additional boilers for heating, but they did not burn oil, but coal.

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

And oil is extracted from crude oil, which cannot be burned directly. It needs to be processed into gasoline, diesel, and kerosene before it can be burned.

However, coal can be burned directly after being dug out, so in the case of ensuring railway transportation, burning coal is undoubtedly cheaper than burning oil, and it is stable and reliable.

Therefore, it is a very good choice to use a boiler for heating in a large shelter. As for the additional maintenance work, the least valuable thing in the apocalypse is manpower. There are tens of thousands of people living in a large shelter. to people to work.

For shelters that are not so large, it is not necessary to adopt such a method. In the case of ensuring the power supply, they can use electric heating for heating, and there is no need to install a boiler for heating.

A private shelter like Chen Xin and Mo Qingyan's can basically meet the heating needs by installing an air conditioner or two electric heaters, but installing a boiler is purely for the money and the brain. , and it is not practical.

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

Although I have prepared an electric heater and an electric blanket for myself, wouldn't it be better to upgrade to make my life more comfortable? Why do you have to wear cold clothes indoors and wrap three layers of quilts when you sleep?

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

The notebook now lists the four items of power supply, lighting, food and medical care in the order that Chen Xin had recorded before. Chen Yu thought about it and added the heating item before lighting.

The power supply system must be the most prioritized option to upgrade, because among the other four items on the notebook, except for medical care, which is not a priority, the other three items will increase the power consumption of the shelter. Power generation is a must.

Moreover, Chen Xin must also consider the problem of fuel consumption caused by power generation. He must know that according to his current electricity consumption, on average, he needs ten liters of gasoline to generate electricity every day. To improve, Chen Xin must consider the replenishment of gasoline and obtain a more durable and efficient way of generating electricity.

If it is a normal situation, the only long-term self-sustaining high-efficiency power generation method that Chen Xin can consider is nuclear power, which he has little access to. The power generation methods in the laboratory research stage are all in his future upgrade plans.

Therefore, Chen Xin is not worried about how to obtain an efficient and durable power generation method. It is enough to upgrade the shelter all the time. As long as there are enough survival points, Chen Xin believes that even if it is an antimatter reactor or a black technology such as an artificial sun The power generation method can also be upgraded.

Although these sci-fi-level technologies are too far away for Chen Xin, and the required survival points are astronomical, under the powerful power of the system, these are indeed things to look forward to.

Although the future is promising, it is still too early to think about these things. The most important thing right now is to re-cultivate the land that was vacated after the vegetables were harvested before, and sow new vegetables, so that there will be enough next month. The harvest went to Mo Qingyan to exchange the materials needed for the upgrade.

However, when he thought of exchanging supplies, Chen Xin felt that he should make a list first to see what supplies he needed now, so that he could have a definite purpose when looking for Mo Qingyan to exchange supplies, and let her prepare in advance to save time. .

You must know that even if Mo Qingyan has a relationship with Uncle Ding, it will take time to get the supplies.
