Chapter 8： Design ventilated lighting (1/2)

”Let’s first think about how to renovate the ventilation system of the base. This is a big problem for underground shelters.”

Sitting on a wooden chair with a slightly shabby bottom, Somo began to recall the knowledge of the civilized age.

and the design of shelters in major doomsday movies...

Underground shelters require a large air filtration and regulation system, but any ventilation ducts that are opened outside will become a safety hazard.

So in Somo’s concept, it is best to use an internal circulation system, but the premise is that water and electricity can be obtained, so that oxygen can be produced by electrolysis, which makes it possible for the internal air circulation of the entire facility.

Of course, it cannot be completely sealed from the outside world. Such a completely sealed environment has extremely poor stability, and ventilation holes to the outside world are still necessary.

For concealment, this kind of vent should not be too big, and there should be a sealable switch that can be closed at any time.

If it is not a restriction of terrain, the best solution is to set the vent under the rock that will only be exposed at the low water level of the river bed, or on an unmanned island.

These slender pipes can draw purified and filtered fresh air into the bunker, and can be closed in a short time, using internal circulation.

But given the current conditions and equipment in the shelter, this idea can only be an idea.

After checking a circle of items currently on sale on the trading channel, Somo decided to use the most mechanical design.

Using the periscope structure of a submarine.

A window with dual functions of ventilation and light was opened in the center of the refuge.

The specific design is to dig out a hole in the front of the shelter and install glass with better light transmittance.

and put holes in the glass for ventilation to ensure that the air can circulate through the pipes.

Follow the dug hole down, and a ”Z”-shaped turning hole can be made in the middle of the hole.

Two plane mirrors that are parallel to each other and form a 45-degree angle with the incident light are installed in the ”Z”-shaped hole. Through two reflections, the incident light is transmitted to the refuge to solve the daytime lighting problem.

After the first layer of ventilated glass, a mechanical explosion-proof glass can be designed to ensure that the explosion-proof glass can be closed in the event of a disaster to prevent liquid or toxic air from flowing in.

Such a simple design, even a high school student can come up with it, but it takes a lot of trouble to implement it.

There is no matching tool. I want to go to a shelter five meters deep under the ground while ensuring accuracy, but it is a big project.

but...

”I have a system!”

With the current understanding of the system, Somo has thoroughly understood the gameplay of the system.

When there is no material, the system wants to use survival points to create materials out of thin air, which is extremely costly.

But when you have the materials, the function of the system is more similar to the role of the construction team, and it only takes a small amount of survival points to achieve the purpose of upgrading.

After contemplating the feasibility, Suma opened the trading channel.

Currently, he can use the following resources:

Ordinary mineral water (1000ml), Youneng water (600ml), 10 kilograms of big white 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 Youneng Water]

[Items needed: explosion-proof glass]

[Remark message: Water that can strengthen the body, don’t miss it when you pass by, only two units of glass, good quality private chat]

...

【Seller: Su Mo】

[Trading item: 15ml mineral water (up to 975ml)]

[Items needed: 1 iron block (single person can exchange 1/1 times)]

【Remark message: Each person can only complete one transaction】

After the two items were successfully put on the shelves, Somo spent 25ml of water to purchase two units of mirrors with good reflective properties and used up all the ordinary mineral water.

Somo exchanges 15ml of water for 1 iron. Although it is an extremely black-hearted merchant behavior, for some players struggling with life and death, it is no less than a savior behavior.

In addition, the reason why everyone can only trade once, Somo also has his own plan.

Water is now as liquid gold. What he wants is to be consumed, not to be bought and hoarded by some interested people.
