Doomsday Bunker Upgrade Chapter 150: Observation room upgrade
"I can upgrade the shelter ()" to find the latest chapter!
Holding the hammer brought from the workbench, Chen Xin hammered the ice in the bunker, panting uncontrollably.
Leaning on his waist, Chen Xin leaned against the wall in the bunker and took a deep breath. Although the oxygen content in the shelter has always been high due to the existence of oxygen generators and planting greenhouses, this location can actually be regarded as the outside world. , After Chen Xin's de-icing just now, he couldn't help but feel short of breath and breathless.
He stretched out his hand and took out an oxygen cylinder from his pocket, opened the protective mask on his face, and took a few breaths into his nose and mouth. Chen Xin, who felt much better, put on the protective mask again and straightened up.
"Huhu, when will this be a head!" Chen Xin couldn't help feeling that after the accumulation of ice, this little hammer in his hand couldn't move it at all. Ice **** down.
This inevitably made him feel a little frustrated. Deicing is not an easy job. It's not like shoveling snow. How can it be cleaned up with a shovel.
But ice, especially frozen ice, is very difficult to clean. In the past, if frozen in many places, the ice would not melt until the beginning of spring to melt the snow.
But now it is impossible for Chen Xin to wait until the temperature rises and the spring blossoms, and the ice accumulates on its own. He must find a way to remove the ice accretion that is at least 30 centimeters thick in front of him.
To be honest, he originally expected ice accumulation, and knew that it would be more serious if it didn't accumulate for a few days, but he didn't expect that the ice would have frozen a foot thick.
Such thick ice accumulates, even with a professional ice axe or iron fiber, it is difficult to clean it up with a sledgehammer, not to mention that Chen Xin only has a small hammer in his hand.
I took a hammer and hit a few more hammers on the ice, but it seemed to have a chat. Except for a little slag, there were no cracks on the ice.
This made Chen Xin frustrated and sighed in his heart that there would be a way to solve these ice accumulations at once, and it would be even better if the ice accumulation problem in the vents could be solved further.
How easy is it to just want to solve a problem? Chen Xin smiled bitterly, and smashed the ice with a hammer.
While hitting it, Chen Xin was also thinking about how to solve the problem of icing.
The main reason for the formation of ice accretion is that the air blown out of the shelter by the vent contains water vapor, which quickly condenses and sinks after being cooled. It freezes into ice before it can fly out, and then accumulates in the here.
This can be seen from the fact that Chen Xin knocked on ice for a long time, and the surface of the protective clothing on his body was frozen.
Taking off the ice on the surface of the protective clothing, Chen Xin sighed. Although he knows the principle, it is not a matter of upgrading the ventilation system to remove the moisture from the air blown out of the vent.
Chen Xin does know how to remove moisture from the air, that is, air drying, but this is mainly a technology used in industrial production. It is too wasteful to use it in the ventilation and exhaust of shelters, and Consumption is also large.
So in Chen Xin's vision, it is enough not to freeze in the small bunker.
In this case, improving the ventilation form of the exhaust vents, or adjusting the structure of the small shelter and changing the vents to the outside can also solve the problem.
But Chen Xin is reluctant to change the vent to the outside, because in that case, the temperature of the air blown out from the vent will be significantly higher than the ambient temperature. It will be as conspicuous as a searchlight in the dark night.
Also, although the vents are not as easy to climb in as in European and American movies, they can still cause many problems if they are discovered.
Now put it in a small bunker. Although there is a possibility of being discovered, it is still much less dangerous.
So to solve the problem, it is best to find a way to make the water vapor freeze without being in the small bunker.
Chen Xin meditated and thought hard, and suddenly a hammer fell, and a flash of light in his mind finally opened his mind.
"I'm so stupid, I can't finish upgrading with the system!" Chen Xin slapped his forehead abruptly, annoyed that the brains he was staying with Qin Lan these days were so confused, he didn't even think of himself. You can also use a system upgrade to solve the problem.
Chen Xin called out the system interface, glanced at the four-digit survival points that had been accumulated on it, and had enough confidence in his heart.
These survival points are prepared by Chen Xin to upgrade the shelter as a whole. He used up some points when he built the ground source heat pump, but he is away from home these few days, but he gets a lot of survival points every day, nearly 40 points per day. The survival point income of the point makes it easy for him to come up with the survival point of transforming and upgrading the small bunker.
"The humble observation room"
“Upgrade plan 1: Increase the area of the observation room, improve the building structure, increase the concealment and air permeability, and enhance the signal receiving ability of the short-wave antenna~IndoMTL.com~700 survival points required for the upgrade”
"Upgrading plan 2: Improve the defense capability of the observation room, improve the strength of the building, increase the performance of thermal insulation, increase the protection of the observation port, and upgrade the required survival point of 1100"
The two upgrade plans are not very cheap, and the emphasis is still different. However, because of the lack of construction materials and the existing materials are all prepared for the overall upgrade of the shelter, Chen Xin did not adopt the two. Upgrade in every way.
After comparing the two schemes, he still chose to spend 700 points to upgrade the first scheme, which is to enhance the concealment and ventilation performance of this small bunker, and at the same time, he can also improve his installation here. The signal reception capability of the shortwave antenna.
Although Chen Xin really wanted the second plan, his survival points should not be consumed too much. After hesitating for a while, he gave up this upgrade option, which was obviously an evolution from a small bunker to a bunker.
After the upgrade, the area of the small bunker has increased a bit, and the overall shape is a perfect circle, but it has not been expanded too much. The observation port is still the same as it is, and there is no change.
It's just that the original vent in the room has become a ventilation duct buried in the wall, which will be ventilated through the facade of the small bunker.
This obviously solves the problem of ice accumulation in the room perfectly at the vent, and because the ventilation duct goes through the outer wall of the observation room, the air coming out of the vent will first reduce the temperature in the ventilation duct before Exhausted, in the infrared perspective, it is not so obvious.
For this point, after the upgrade, Chen Xin came out of the gate of the shelter and used the infrared vision function of the tactical goggles to observe the position of the observation room. Traces of air.
