Chapter 46: Considerations for 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 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 several tens of degrees below zero is indeed a desperate situation, but with the current human technology, it is no 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 can withstand the extreme cold and low temperatures of tens of degrees below zero in the polar environment.
　　 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 mankind, as long as the shelter is built with heat preservation and protection, and equipped with reliable heating equipment, it is enough to ensure that a shelter can be warm and comfortable in an environment of tens of degrees below zero.
　　 But 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.
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 easy to install and maintain, and the temperature can be controlled at will, clean and clean, but sometimes most of the power in the scientific research station is used In terms of 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 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 the generator load.
In addition, some small summer scientific research stations only have simple gas heating equipment, and use special gas heating to burn cans of liquefied gas or natural gas indoors. However, you 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 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 the city used the method of building additional boilers for heating, but they burned coal instead of oil.
　　The oil reserves of Yanguo are not particularly abundant, but coal resources are relatively abundant. After all, Yanguo's oil reserves 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.
Therefore, it is a good choice for large-scale refuges to use boilers for heating. As for the extra maintenance work, the least valuable in the end times is manpower. A large-scale refuge can live in tens of thousands of people, and there is no need to worry about finding it. Go to work.
　　 For shelters that are not so large in scale, it is not necessary to adopt such a method. When the power supply can be guaranteed, they can use electric heating for heating, and there is no need to install a heating boiler.
For private refuges like Chen Xin and Mo Qingyan, installing an air conditioner that can heat or preparing two electric heaters can basically meet the heating needs. Installing a boiler is pure money to burn plus brain pumping. , And it's not practical.
　　 However, this incident reminded 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 good 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.
　　 The four items of power supply, lighting, food, and medical care are written in the notebook in the order that Chen Xin previously recorded. Chen Yu thought about it and joined the heating project before the light.
The power supply system must be the most priority upgrade option, 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 electricity consumption of the shelter, so upgrade the power supply system to improve the shelter’s power Power generation is a must.
Moreover, Chen Xin must also consider the fuel consumption caused by power generation. UU reading www.uukanshu.com needs to know that according to his current electricity consumption, the average gasoline used to generate electricity needs ten liters a day, and with the increase in electricity consumption , The consumption of oil will inevitably increase, Chen Xin must consider the supplement of gasoline and obtain more durable and efficient power generation methods.
If it is normal, the only long-term self-sustaining high-efficiency power generation method that Chen Xinneng considers is nuclear power, which is almost inaccessible, but for Chen Xin who has a system, geothermal power generation and geomagnetic power generation are still in science fiction and experimentation for humans. The power generation methods used in the research phase of the laboratory are all 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 upgrade the shelter. As long as you continue to upgrade and have enough survival points, Chen Xin believes that even if it is an antimatter reactor or a black technology like 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 survival points needed 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 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 so that there will be enough in the next month. Go to Mo Qingyan for the supplies needed for the upgrade.
However, thinking of exchanging supplies, Chen Xin felt that she should make a list first and see what supplies she needed now, so that she could be targeted when looking for Mo Qingyan to exchange supplies and let her prepare in advance to save time. .
　　 You need to know that even if Mo Qingyan has a relationship with Uncle Ding, it will take time to get supplies.
