Doomsday Bunker Upgrade Chapter 46: Considerations on heating

　　 For humans, although the environment of tens of degrees below zero is indeed a restricted area of ​​life, it is completely unsuitable for human survival, but even in the worst polar regions, humans have also built permanent polar scientific research stations. Moreover, the scientific research station is not buried deep underground, but directly placed 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.

　　Take the scientific research station built by Yanguo 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 panels. It is warm and beautiful, and it can withstand tens of degrees below zero in the polar environment. Severe cold and low temperature.

　　 Of course, the scientific research station itself does not produce temperature, even if the heat preservation is done well, heat exchange is still taking place, so the scientific research station itself still has heating equipment.

　　 But this is enough to prove that the existing technology of mankind 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 well insulated and equipped with reliable heating equipment, it is enough to ensure that a shelter can be warm and comfortable even in an environment of minus tens of degrees.

　　 However, reliable heating equipment is not so easy to guarantee in this end-time era.

　　Take the polar scientific research station as an example. Generally speaking, there are two heating methods, electric heating and fuel heating.

Because scientific research stations usually generate electricity 24 hours a day, larger scientific research stations generally use indoor electric heating for heating. This method is easy to install and maintain, and the temperature can be controlled at will, and it is clean and clean. Electricity is used for heating. When the external environment temperature is low, it is easy to cause the generator to be overloaded, and improper use can easily cause electrical fires.

　　 Some scientific research stations use oil-fired boilers as the main heating equipment, similar to the ordinary heating in the northern part of the country. This requires additional installation and maintenance of heating equipment, but it is not prone to electrical fires and other accidents, which can effectively reduce power generation machine 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 keep an eye on carbon monoxide in the air. concentration to avoid carbon monoxide poisoning.

　　 These three heating methods are mature and reliable heating methods. Although each has its own advantages and disadvantages, they can meet the heating needs of the shelter.

　　According to Chen Xin's understanding, the three large-scale shelters in this city all use additional boilers for heating, but they burn coal instead of oil.

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

　　 And the oil extracted from oil is crude 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 when it is dug out, so if rail transportation can be guaranteed, burning coal is undoubtedly more worthwhile than burning oil, and it is more stable and reliable.

　　 So it’s a good choice for large refuges to use boilers for heating. As for the extra maintenance work, the least valuable in the end times is manpower. A large refuge can live in tens of thousands of people, not at all. Anxiety can't find anyone to work.

For shelters that are not so large in scale, it is not necessary to adopt such a method. Under the circumstance that the power supply can still be guaranteed, they can use electric heating for heating, and there is no need to install heating equipment. boiler.

For a private shelter like Chen Xin and Mo Qingyan's, installing an air conditioner or two electric heaters can basically meet the heating needs, and installing a boiler is purely for the extra money. Brain pumping, and not practical.

　　 But this incident reminds Chen Xin that the heating system should be on the agenda in the refuge upgrade plan.

　　 Although I have prepared electric heaters and electric blankets for myself, wouldn’t it be a good idea to upgrade to make myself more comfortable? Why do you have to wear cold-proof clothes indoors and sleep with three layers of quilts?

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

In the notebook, the four items of power supply, lighting, food, and medical care are written in the order that Chen Xin had previously recorded. After thinking about it, Chen Yu 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. Therefore, upgrading the power supply system to improve The amount of electricity generated by the shelter is a must.

Moreover, Chen Xin must also consider the fuel consumption problem caused by power generation~IndoMTL.com~ To know that according to his current electricity consumption, on average, he needs ten liters of gasoline to generate electricity every day, and with the increase of electricity consumption , The consumption of fuel will inevitably increase, Chen Xin must consider the supplement of gasoline and obtain a more durable and efficient way of power generation.

　　 If it is normal, the long-term self-sustaining high-efficiency power generation method that Chen Xinneng considers is only nuclear power, which is almost inaccessible to him, but for Chen Xin who has a system, geothermal power generation and geomagnetic power generation are still in place for human beings. Both the science fiction and laboratory research phases of power generation are in his future upgrade plan.

Therefore, Chen Xin is not worried about how to obtain an efficient and long-lasting power generation method. It is enough to keep upgrading the shelter. As long as there are enough survival points, Chen Xin believes that even if it is an antimatter reactor or an artificial sun In this way, the power generation method of black technology can also be upgraded.

　　 Although these sci-fi-level technologies are too far away for Chen Xin and the survival points needed are also astronomical, under the powerful power of the system, these are indeed things that can be expected.

　　 Although the future is promising, it’s too early to worry about these things. The most important thing at the moment is to replant the land that was vacated after the vegetables were harvested in the greenhouse and plant new vegetables for next month. Can have enough harvest to find Mo Qingyan to exchange the materials needed for the upgrade.

But thinking of exchanging supplies, Chen Xin felt that he should make a list first to see what supplies he needs now, so that he can have a definite purpose when looking for Mo Qingyan to exchange supplies, and let her prepare in advance, okay Can save time.

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