Chapter 8 Design of Ventilation and Lighting
"Let's think about how to transform the ventilation system of the base first. This is a big problem for underground shelters."
Sitting on a wooden chair that was a little uncomfortable, Su Mo began to recall the knowledge of the civilized era. Google search reading
And the shelter design in major doomsday movies
Underground shelters require a large air filtration and regulation system, but any ventilation ducts opened outside will become a safety hazard.
So in Su Mo's conception, it is best to use an internal circulation system, but the premise is that there must be water and electricity, so that oxygen can be produced by electrolysis, which provides the possibility for the internal air circulation of the entire facility.
Of course, it cannot be completely sealed from the outside world. This completely sealed environment has extremely poor stability, and ventilation holes leading to the outside world are still necessary.
In order to conceal, this vent cannot be too large, and there must be a sealed switch that can be closed at any time.
If it is not a terrain restriction, setting the vent under the rocks that are exposed only when the riverbed is low water level, or on an uninhabited island, is the best solution.
These slender pipes can draw purified and filtered fresh air into the shelter, and can be closed at any time to adopt internal circulation.
But considering the current conditions and equipment in the shelter, this idea can only be a conception.
After checking the items currently on sale on the trading channel, Su Mo decided to use the most mechanical design.
Use the submarine's periscope structure.
Open a window in the center of the shelter that serves both ventilation and lighting.
The specific design is to dig a hole in the top of the shelter and install glass with relatively good light transmittance.
And make holes for ventilation on the glass to ensure that air can flow through the pipes.
Going down along the dug hole, a "Z"-shaped turning hole can be made in the middle of the hole.
Install two parallel plane mirrors at a 45-degree angle to the incident light in the "Z"-shaped hole. Through two reflections, the incident light is transmitted to the shelter to solve the problem of daytime lighting.
After the first layer of ventilation glass, a mechanical explosion-proof glass can be designed to ensure that the explosion-proof glass can be closed in a disaster to prevent liquid or toxic air from flowing in.
Such a simple design can be thought of even by a high school student, but it is troublesome to implement it.
Without matching tools, it is a big project to penetrate the shelter five meters underground while ensuring accuracy.
However
"I have a system!"
With his current understanding of the system, Su Mo has completely understood how the system works.
When there are no materials, the system wants to use survival points to create materials out of thin air, which is very costly.
But when the materials are available, the system functions more like a construction team, and only needs to spend a small amount of survival points to achieve the upgrade purpose.
After thinking about it and confirming the feasibility, Su Mo opened the trading channel.
At present, the resources he can use are as follows:
Ordinary mineral water (1000ml), psionic water (600ml), and 10 kilograms of black bread.
As for the remaining pet eggs and energy bicycle drawings, he does not intend to trade them.
Trading channel
[Seller: Su Mo]
[Trading Item: 50ml Psionic Water]
[Required Item: Explosion-proof Glass]
[Notes: Water that can strengthen the body, don't miss it if you pass by. Only two units of glass are accepted. Good quality ones can be exchanged privately]
[Seller: Su Mo]
[Trading Item: 15ml Mineral Water (up to 975ml)]
[Required Item: 1 Iron Block (1/1 number of exchanges per person)]
[Notes: Each person can only complete one transaction]
After the two items were successfully put on the shelves, Su Mo spent another 25ml of water to buy two units of mirrors with good reflective performance, and used up all the ordinary mineral water.
Although Su Mo used 15ml of water to exchange for 1 iron block, it was an extremely black-hearted businessman's behavior, but for some players struggling on the line of life and death, it was no less than the behavior of a savior.
In addition, Su Mo also had his own plan for limiting each person to only trade once.
As for water, now as liquid gold, what he wants is to be consumed, not to be purchased and hoarded by some people with ulterior motives.
World chat channel
"If you are short of water but have iron blocks, go to the trading channel and check. Su Shen is selling water again! One person can only trade once, hurry up!"
"Fuck, Su Shen is generous!"
"Haha, it's too late. Fortunately, I followed Su Shen's personal channel in advance, so I got a sip of water. Don't you see that Su Shen now has more than 400,000 fans. How can you passers-by get it?"
"Where did Su Mo get the water? Yesterday he spent 700ml to buy the illustrated book, and today he bought 1000ml of iron blocks. Is it too much?"
"Go and see, the psionic water that Su Shen hung can actually strengthen the body and cure diseases. As long as there is explosion-proof glass, who has it? Go and change it!"
"Alas, people are so annoying. I dug all morning and didn't dig a drop of water. I'm dying of thirst."
""
There is only one speech per day, and a large group of people gather in the world channel to discuss, not to mention the grand occasion of the regional channel.
Even Su Mo's personal private messages were overwhelmed at this time.
First, in less than two seconds, the iron blocks that were put up for sale were traded, and 65 units of iron blocks were now quietly lying in the inventory.
Even so, countless people were holding other resources and shouting to exchange them for a sip of water.
"Water is too popular!"
Su Mo thought to himself.
These two days, others have been using resources to buy water, but he is the only one who is using water to exchange for resources, so he naturally looks unique.
Using the filtering function in the private message, Su Mo used the keyword "iron block" to filter out 80% of the useless private messages.
After using the search, he picked out dozens of private messages with explosion-proof glass and began to check.
After flipping through many private messages that wanted to use ordinary quality explosion-proof glass to buy more water, Su Mo finally found a bright one.
Feng Mengyue: "Su Shen, I have an ordinary quality explosion-proof glass, but I think you will definitely not like it. If you are willing to increase the price, I can trade you a piece of excellent quality and a piece of rare quality explosion-proof glass."
The avatar is a woman with a delicate face and a heroic look.
Seeing the excellent and rare, Su Mo's eyebrows jumped and smiled.
The current quality classification is temporarily divided into five levels: ordinary, excellent, excellent, perfect, and rare.
Feng Mengyue, a woman of her generation, was able to get the rare quality explosion-proof glass on the second day of the game. Her luck is obvious.
"She asked for a higher price as soon as she opened her mouth, but she didn't offer the price actively. It seems that she is a difficult person."
Su Mo shook his head and didn't fall for it. Instead, he responded.
Su Mo: "You should understand the current value of the phantom water. There are so many things on the market, but I am the only thing that can improve physical fitness. As for the explosion-proof glass, I bought it to replace the windows of the shelter. It doesn't matter if it's better or worse."
Feng Mengyue: "Is 300ml okay?"
Su Mo: "Don't even think about it. It's just two pieces of glass. It's not worth so much. If you don't want it, I will drink it in the afternoon."
Feng Mengyue: "I'll think about it."
Seeing the other party's reaction, Su Mo laughed dumbly.
He was the only one selling phantom water in the market. It was an absolute seller's market. Once he decided not to sell it, the buyer could only stare blankly.
Two minutes later, Feng Mengyue's message came again.
Feng Mengyue; "Two pieces of glass and I'm adding one piece of information, 300ml of psionic water"
Su Mo: "What information?"
Feng Mengyue: "Information about how I got these pieces of glass"
Looking at the chat box, Su Mo thought about it and then chose to agree.
In the end times, materials have a price, but information is priceless.
For example, if he doesn't have enough information to kill a chameleon, he might just be a food delivery man in his full gear.
After hanging up the private trading channel and uploading the designated seller of 300ml of psionic water, the transaction is completed.
[Record]: You lost 300ml of psionic water.
[Record]: Congratulations on getting 1 explosion-proof glass (excellent), and 1 explosion-proof glass (rare).
[Record]: Do you want to extract the glass information?
"Extract"
After the words fell, a voice was played in the empty shelter.
"Ruins will be refreshed from time to time in the wilderness. When I woke up today, a mysterious ruins refreshed next to me. It looked very dangerous inside, so I only looted a few pieces of glass on the periphery. When I wanted to continue exploring, the ruins suddenly disappeared."
Has anyone watched it? It feels like a stand-alone game. Crying... (woo woo woo)
