Doomsday: Humanity shrinks 100 times

Chapter 138 Exhaust and Heat Dissipation

The basic infrastructure of kitchen facilities is nothing more than sinks, cabinets, kitchen utensils and so on.

There is also the connection to the water system and sewage system. These are familiar tasks and there will be no problem as long as you are patient.

The difficult work mainly requires a stove, as well as issues such as replacing the stove's heat source and dealing with the steam generated during heating.

Because of their special heating method, they only need to use aluminum products to convert heat, and the way they store heat is through blocks of processed aluminum.

So in form, the way this stove replaces its heat source is somewhat similar to the installation and removal of batteries.

When a piece of aluminum has lost all its heat, it can be removed and replaced with a new one, ultimately making a removable setup.

In addition, when aluminum products release heat, they will generate higher heat at close range. Previously, because they worked outdoors, the heat released would be quickly absorbed by the surrounding air.

However, after moving indoors, this problem will become prominent. If people stay in the kitchen, it may be like a sauna, or even feel hotter than this.

After the reduction, the burn problem is still quite dangerous.

It is easy to understand that when cooking with fire in the non-shrinking state, people are at a certain distance from the heating source.

But after shrinking, if you want to cook, the distance between people and the heat source is actually only a few millimeters. This is undoubtedly like putting ants next to a fire. If the heat is high enough, the ants will be scalded to death almost instantly.

Several people discussed this issue.

"First, we need to build a layer of insulation to prevent the heat radiation from the aluminum sheet from directly causing burns to the human body."

"There's another issue we need to consider. Currently, the heat generated by the aluminum sheets isn't enough to cause the wood products to flash over. However, if Yunxin's capabilities are sufficient in the future, we'll also need to pay attention to fire prevention. After all, we live in trees, and this can be quite fatal."

Lu Yuning listened to Zhang Xinyue and Zhang Qian's discussion, nodded, and then said, "In that case, let's use stone slabs as the insulation layer, and then add a layer of mud around the stone slabs. This is actually similar to the stoves in the countryside. It can both insulate and prevent fire, and leave an outlet on the top for heating."

"In this case, the heating source cannot come into direct contact with the water. Will there be insufficient heat?" Zhang Qian thought for a moment and asked.

"So we have to use aluminum pots for cooking. Aluminum has better thermal conductivity. Although there will be some heat loss, it is still within an acceptable range."

"The pot also needs to be insulated," Zhang Xinyue reminded.

Both of them nodded.

The final plan was finalized, which was to first build an insulating layer with mud, sand and stone slabs, and place an aluminum heat source in the middle.

The pots used for cooking are made of aluminum, mainly because aluminum has better thermal conductivity. In this way, when the aluminum pot is placed directly on the heat source, the heat loss is relatively small.

Construction began soon after the plan was finalized. Since metal manipulation was required, Lu Yuning had to make the aluminum pot himself.

Finally, after several tentative failures, the thing was quickly made.

Zhang Qian looked at the exquisite stove, and the chef's soul awakened immediately. Her eyes lit up, and she couldn't wait to try it out, including the loading and unloading of the heat source and the heating and cooking process.

But Lu Yuning still stopped her.

"There is also the problem of water vapor that needs to be solved," Lu Yuning said.

"Oh, I forgot about it." Zhang Qian nodded embarrassedly.

Lu Yuning smiled. It seemed that everyone had different hobbies. He didn't quite understand the joy of cooking, but seeing Zhang Qian's enthusiastic look, he decided to finish the remaining work as soon as possible and let her experience it.

"There are two aspects to deal with the water vapor issue," Lu Yuning said.

"Uh-huh"

"The first thing is to ensure ventilation, so we need to build a ventilation pipe, but not for smoking, but for water suction. And then we must build a separate window in the kitchen."

Lu Yuning looked at everyone after he finished speaking. "Well, can the ventilation pipe suck out the moisture? I remember that we need to use a range hood to suck out the fumes from cooking rice at home," someone asked.

"The chimney effect mainly relies on the difference in air density caused by temperature differences, which in turn creates a pressure difference, and hot air will automatically flow outdoors."

Zhang Xinyue explained.

"I see"

After some discussion, everyone learned some useless little knowledge...

Based on this assumption, the water vapor problem is easier to solve, but some modifications need to be made on this basis. Because water vapor is exhausted, there will be problems of water vapor condensation and backflow.

So we need to make an S-shaped exhaust duct and leave a drain outlet at the bottom.

And aluminum is used to make the exhaust duct, mainly considering the thermal conductivity of aluminum. The heat retained in the kitchen can be conducted out through the aluminum pipe, which is more perfect.

This kitchen set consumes a lot of aluminum, but fortunately Lu Yuning had brought back two cans before.

There are no special requirements for the food storage room that comes with the kitchen, as long as it is kept dry, so Zou Yunxin is responsible for drying it and then laying a layer of stone slabs.

At Zhang Qian's request, some partitions and shelves were built inside, mainly to make it easier to distinguish things, otherwise things would be piled together and difficult to find.

The shelves are used to store small pieces of processed food.

...

"nailed it"

After Lu Yuning put the aluminum pot into the stove, the overall construction of the kitchen was almost completed.

The construction of this kitchen was quite time-consuming. After everyone had been busy for a while, it was already noon.

The main reason is that many things need to be made of aluminum, and Lu Yuning has to do it himself. Others can only watch, and efficiency immediately drops.

It was lunchtime now, and Zhang Qian planned to cook a meal in this new kitchen to test the effect.

Others were busy repairing and decorating the restaurant, such as the partition from the living area and the windows.

In fact, there is a more difficult problem when there are more buildings.

Due to lighting issues, windows have to be opened in almost every space, which causes the shelter's concealment to plummet.

However, this is a difficult problem to solve. In the absence of indoor lighting, the window must be opened.

Therefore, after comprehensive consideration, we can only do some concealed decoration on the windows and provide good protection.

This ensures that even if the location of the shelter is discovered when defending against the enemy, these windows will not become a breakthrough point.

Fortunately, the location they chose for their shelter is relatively high, so it is generally difficult to find.

Moreover, the plastic used to make windows is also relatively strong.

On this basis, make another layer of internal windows, which can be opened and closed from the inside.

Every window needs to be treated in this way, and it has to be done very carefully, without any carelessness.

In addition, everyone brainstormed and made some devices that might be needed.

Tables, chairs and benches are the basics, and there are also serving tables, drinking fountains, etc.
