Doomsday: Humanity shrinks 100 times

Chapter 136 Floor Heating
Liu Rui and Xia Fei made some preparations, took some water and food, and headed towards the forest area with high spirits.

Although the forest area is actually very small when riding a chipmunk, it can be described as vast and boundless if you just rely on your legs.

So Lu Yuning reminded them again to be careful about getting lost, and the two nodded to show that they understood.

The jungle work has begun, and the expansion work of the shelter will also officially start.

The first problem with expansion is determining what facilities are essential.

In addition to dormitories, toilets, bathrooms and other basic facilities, everyone discussed a few more.

The issue with the most votes is restaurants, which concerns the most basic people's livelihood issues, so the most people think of it.

The main purpose of a restaurant is to facilitate the storage and management of food, as well as the disposal of leftovers and tableware.

Moreover, shared dining places help to enhance group feelings.

After all, eating is a time to rest and relax, and people prefer to chat about family matters while eating.

The restaurant is naturally equipped with a kitchen and food storage room, so there is a lot to do in the restaurant.

After the kitchen, the second most voted area was the conference room.

There is nothing much to say about this. Due to development needs, there may continue to be goal planning and discussions.

Their current discussion room was just a space dug out temporarily by Lu Yuning. The facilities were rather simple and the lighting was insufficient.

So it might be necessary to make some modifications on this basis. Lu Yuning plans to get a sketchpad or something like that, and ask Zhang Xinyue to draw all the explored areas nearby to facilitate subsequent exploration planning.

Next is Zhang Xinyue’s unique tower studio. Because the renovation cost is relatively high, we have decided to keep it as it is for the time being and just add some work accessories.

In addition, Lu Yuning proposed two more facilities, an item manufacturing room and a material storage room.

Like the kitchen, the manufacturing room and storage room are also supporting facilities, mainly for Lu Yuning to make items.

Some commonly used materials are placed in the storage room for easy access.

Finally, someone suggested setting up an entertainment room. After all, mental satiety is as important as physical satiety, and a combination of work and rest is more efficient. However, there is nothing for entertainment now. However, Lu Yuning decided to make it first, mainly because it doesn't take much time.

Eventually the necessary facilities for the expansion were determined.

The next step is construction planning, which is Zhang Qian's area. How to place so many facilities is a big problem.

"Taking into account the issue of light, the structure cannot be like a normal villa-style building, but must be spread out horizontally," said Zhang Qian.

Lu Yuning nodded, already understanding what she meant.

Because they live in a tree hole and there is no electricity, indoor lighting is a problem.

If we dig inward, because the trunk is thick, we can't open windows to let in light, and the lighting inside will definitely be insufficient. Therefore, the best way is to dig all the facilities around the outside of the trunk, which is more like carving on the flat surface of a cylinder.

"However, if it's expanded too wide, it would be difficult to connect to the central heating and water systems. So, for now, it can be divided into two floors. For example, the living area can be placed on the upper floor. Normally, the kitchen and dining room should be separated into separate areas. However, our actual living areas are very small now, and the smell of food has a minimum diffusion range. Unless it is very far away, it doesn't make sense."

"Then try to separate the kitchen from the living area and build a partition in the middle," suggested Zhang Xinyue.

"Well, finally there's the heating issue. How are you going to fix it?"

Lu Yuning thought for a moment, then said, "Since we can now process metal materials, I'm considering using collective heating. The heat utilization rate is relatively high, and it is easier to control the temperature."

Zou Yunxin rushed in upon hearing this: "I know this. In the north, we all have collective heating in winter, usually with floor heating."

Lu Yuning nodded. "Yes, that's how it was originally designed. I understand that the hot water pipes should be buried under the floor, using hot water to provide heat. Water has a greater specific heat capacity, dissipates heat more slowly, has a high heat utilization rate, and provides even and comfortable heating."

"Yes, there is usually a boiler room dedicated to supplying hot water to residential areas," Zou Yunxin interjected.

Zhang Qian said, "I understand. In this way, the hot water can be diverted. Some of it will flow into the floor heating pipes, and some will flow into facilities like the bathroom and kitchen. This will provide a stable supply of hot water."

"Well, but this is under ideal circumstances. The heating system will be different after it is reduced in size. It may need to be processed again, and the heating and hot water supplies must be separated," Lu Yuning said helplessly.

"What?"

"It's similar to some simple machines. Some mechanical devices can operate from a normal perspective, but when scaled down, many physical phenomena are different. For example, this heating system actually uses very little water. Even if the specific heat capacity of water is large enough, the heat it carries is very small and dissipates quickly. Moreover, due to evaporation, if you want to provide heating all day, the water consumption is quite alarming. Therefore, unlike circular central heating, we need to make the heating system self-enclosed, ensure the internal water temperature is constant, and insulate the heating equipment to slow down the heat dissipation rate."

A few people nodded and seemed to understand.

"So how do we do it specifically?"

"Actually, it's quite simple if we don't consider the temperature control system. We actually have very little water, so we don't need circulating heating. All we need to do is make a tubular container, fill it with water, and heat one end of the container. The water in the container will naturally heat up at the same time. But how to control the temperature is up to Xinyue to figure out. Anyway, this won't affect the expansion of the shelter. We can just bury the heating pipes in advance."

Everyone nodded.

In this way, the design of the shelter has been basically finalized. As for the specific architectural details of each facility, we will consider them when it is actually built. In short, practicality is the main thing, and convenience is secondary. If it is really impossible to realize it, we will not consider it for the time being and will deal with it when we have enough capabilities in the future.

So the expansion of the shelter officially began.

Han Yingying expanded the collaborative capabilities and everyone joined in the construction work.

The first step is naturally to excavate the space, a task that Lu Yuning is already very familiar with.

The others were enjoying it, and they felt it was very novel every time they used Lu Yuning's ability.

The excavation and construction work proceeded smoothly in an atmosphere of great enthusiasm among everyone.

The only difficulty in this work lies in the connection between the first floor and the second floor. Considering both aesthetics and practicality, we finally built a spiral staircase.
