For humans, although the environment of dozens of degrees below zero is indeed a forbidden area of life and completely unsuitable for human survival, even in the polar regions with the harshest environment, humans have still built permanent polar scientific research stations, and scientific research The station is not buried deep underground, but placed directly on the surface.
A low temperature of dozens of degrees below zero is indeed a desperate situation, but with humankind's current technology, there is no problem in building a warm and comfortable scientific research station in this environment.
Take 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. It is both warm and beautiful, and can completely withstand the severe cold temperatures of 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 is still happening, so the scientific research station itself still has heating equipment.
But this is enough to prove that human beings' existing technology does not really need to dig thousands of meters underground when facing severe cold temperatures.
With the current scientific and technological strength of mankind, as long as the shelter is well insulated and equipped with 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.
However, reliable heating equipment is not so easy to guarantee in this apocalyptic era.
Taking polar scientific research stations as an example, there are generally two heating methods 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 simple and easy to install and maintain. The temperature can be controlled at will and it is clean. However, 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 also easily cause electrical fires.
Some scientific research stations use oil-fired boilers as their main heating equipment, similar to ordinary heaters in northern China. This requires additional installation and maintenance of heating equipment, but it is less prone to accidents such as electrical fires and can effectively reduce generator load.
In addition, some small summer scientific research stations only have simple gas heating equipment. They use special gas heaters to burn canned liquefied gas or natural gas indoors, but they need to pay attention to ventilation and pay attention to the concentration of carbon monoxide in the air at all times to avoid poisoned by carbon monoxide.
These three heating methods are all mature and reliable heating methods. Although each has its own advantages and disadvantages, they can all meet the heating needs of the shelter.
According to Chen Xin's understanding, the city's three large shelters all use additional boilers for heating, but they burn coal instead of fuel.
Yanguo's oil resource reserves are not particularly abundant, but its coal resources are relatively abundant. After all, Yanguo's oil reserves are the ninth in the world, but its coal reserves are the third in the world.
Moreover, crude oil is extracted from oil, which cannot be burned directly. It needs to be processed into gasoline, diesel, and kerosene before it can be burned.
But coal can be burned directly after being dug out. Therefore, if railway transportation can be guaranteed, burning coal is undoubtedly more cost-effective than burning oil, and it is stable and reliable.
Therefore, it is a very good choice to use boilers for heating in large shelters. As for additional maintenance work, the most valuable thing in the apocalypse is manpower. Tens of thousands of people can live in a large shelter, so there is no need to worry about finding it. Work for people.
For shelters that are not that large, there is no need to adopt such an approach. As long as the power supply can be guaranteed, they can use electric heating for heating. There is no need to install a heating boiler.
For a private shelter like Chen Xin and Mo Qingyan's, installing an air conditioner or preparing two electric heaters can basically meet the heating needs. Installing a boiler is purely a matter of money and brains. , and it’s not practical either.
However, this incident reminded Chen Xin that the heating system should be put on the agenda in the shelter upgrade plan.
Although you have prepared an electric heater and an electric blanket for yourself, wouldn’t it be nice to upgrade to make yourself more comfortable? Why do you have to wear cold-proof clothing indoors and wrap yourself in three layers of quilts when sleeping
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 contains the four items of power supply, lighting, food and medical care in the order that Chen Xin previously recorded them. Chen Yu thought about it and added the heating item before lighting.
The power supply system must be the top priority to upgrade, because among the other four items on the laptop, except for medical care, which is not a priority, the other three items will increase the power consumption of the shelter. Therefore, upgrading the power supply system will improve the shelter's power consumption. Generating electricity is something that must be done.
Moreover, Chen Xin must also consider the fuel consumption caused by power generation. He must know that according to his current electricity consumption, on average, ten liters of gasoline are needed to generate electricity every day. As electricity consumption increases, fuel consumption will inevitably increase. To improve, Chen Xin must consider replenishing gasoline and obtaining more durable and efficient power generation methods.
Under normal circumstances, the only long-term self-sustainable and efficient power generation method that Chen Xin can consider is nuclear power, which he has almost no access to. But for Chen Xin who has a system, geothermal power generation and geomagnetic power generation are still science fiction and experiments for humans. The power generation methods in the laboratory research stage are among his future upgrade plans.
Therefore, Chen Xin is not worried about how to obtain an efficient and long-lasting power generation method. He just needs to keep upgrading the shelter. As long as he keeps upgrading and has enough survival points, Chen Xin believes that even if it is a black technology like an antimatter reactor or 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 number of survival points required is astronomical, under the powerful power of the system, these are indeed things that can be expected.
Although the future is promising, it is still too early to worry about these things. The most important thing right now is to re-cultivate the land vacated after harvesting vegetables in the greenhouse and sow new vegetables so that there will be enough next month. He went to Mo Qingyan to exchange the harvest for the materials needed for upgrading.
However, when thinking about exchanging supplies, Chen Xin felt that he should make a list first to see what supplies he needed now. This would help him to have the right target when looking for Mo Qingyan to exchange supplies, and allow her to 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 supplies. (End of chapter)
