I was a village chief in a primitive society

Chapter 546: Heating. (2 more, please customize)

Twenty minutes later, everyone’s faces were covered with a thin layer of crushed petals, and they all sat on stools, looking up at the ceiling.

"Wu, how long does it take for us to wash our faces? Yan Hua asked in a murmur, her tone was very confused, probably because her face was covered with petals.

"It'll be ready in ten minutes. I'll call you when it's ready to wash."Su Bai said

"good."The girls answered in vague voices again.

Su Bai walked to the side and sat down, took out paper and pen and continued to arrange what to do next.

A different idea suddenly came to his mind, so he wanted to Present this idea quickly

"swish swish......."

The quill collided with the paper and made a constant rustling sound, which was particularly loud in the quiet snowy day.

Yanhua glanced sideways and asked doubtfully:"Witch, what are you doing? Do you need our help?"

Because Niujiao Niang had nothing to do, her ears were very good at hearing, and she also heard those rustling sounds.

"Please concentrate on applying the mask first. I will call you later if I need your help."Su Bai said softly.

He really couldn't do anything with Niujiao Niang. She was so active that she couldn't stop at any time.

"good." Yanhua twisted her stiff neck and returned to the original position, not daring to move too much for fear that the mask on her face would fall off.

Su Bai raised his head and glanced at the girls, then lowered his head and continued writing his thoughts.

He looked at The piece of paper murmured to itself:"First of all, we need to change the temperature inside, otherwise it will be too cold."

Although Yong'an Building is a cement house, which can isolate the cold wind outside, the temperature outside is about the same as the temperature inside. At most, the lit fire pit will give people a slightly warm feeling, but it is just scratching the surface..The pattern drawn on the paper is the appearance of Yongan Building, as well as the internal structure diagram inside, followed by some relatively dim lines, all of which are distributed on the walls inside Yongan Building. In fact, these dim lines are from the pipes , but it’s not very obvious when drawing.

The thickness of these pipes is not very large, probably about the size of a wrist, but they are evenly distributed, and are found in all rooms, large and small, from the first floor to the fourth floor.

Also This pipe is not only found in the room, but also in the living room and kitchen outside, and even in Coco's laboratory.

These faint lines all enter from the corner of the room, and then continue along the bottom of the wall , and finally connected to a black blind.

Then it goes through to the next room, and is connected to the longitudinal pipe at the end. There will be a row of wooden guardrails on the edge of the pipe to isolate it. Someone will encounter these pipes.

All of these pipes finally converge into the open space behind Yong'an Building. There is also a separate house drawn on the open space. This house is next to the water storage tank of the water heater, and the end of the pipes is all They are all in that house.

Then there is an oversized box in this house. The lower part of it has nothing and is completely hollow. There is a huge smoke outlet on the top, which is similar to the house on the other side of the earth. The chimney is very similar.

Secondly, there are many pipes connected to the box, and these pipes are connected to the water storage tank, which seems to allow the water to continuously enter this large box. After washing the Yanhua Face came over, saw a picture and wondered:"Wu, why did you draw Yong'an Tower?"

The Niujiao Niang couldn't wait any longer. She ran to wash her face before waiting for fifteen or twenty minutes, and then came over quietly.

"Come and guess, Yuying guessed it once before, this time it’s your turn."Su Bai said softly.

He had been preparing for this drawing for several days, and had already asked people to make the necessary materials in advance. As long as he completed the drawing completely and understood some of the principles, the plan would be ready. It's time to start implementing it.

Yanhua has completely brought her eyes over and is looking at it very seriously. She is holding the paper and looking at the ceiling.

She frowned, shook her head and said:"Wu, I don't know anything." I can’t guess, what is this going to do?"

Yu Ying just finished washing her face and came over. After taking the drawing, she began to browse it.

She also looked at it carefully for a long time and guessed:"Witch, why does this look so similar to the one taking a bath?"

"This is similar to the principle of taking a bath, but it’s not really about taking a bath."Su Bai said softly. He has probably been thinking about this design for a long time. He has thought of this since the ice and snow first arrived and it was very cold.

But since there are very few available things, he has to prepare to collect materials and study the principles. It wastes a lot of time

"Wu, I can’t guess it either."Yu Ying shook her head in despair.

Even if she thought about it, she couldn't figure out what these things were, because it couldn't be something for bathing, and the whole thing was different.

"This can be of great use in times of heavy ice and snow, as it can warm the entire room."Su Bai explained simply.

Yanhua opened her red eyes in disbelief and said in shock:"Wu, can this make the whole room warmer?"

"Do you want all the hot water to run in?"Yu Ying asked innocently

"Ha ha ha ha......Don't let all the hot water run in."Su Bai said cheerfully and explained,"This is to let the hot water boil in the boiler in this small house, and the very hot water vapor will enter the room along the pipes."

Su Bai took a cup of hot water and took a sip, and continued to explain:"Finally, we will use this small radiator to increase the temperature in the room. As long as we close the doors and windows of the room, the entire Yong'an Building will become warmer. stand up."

He explained while pointing to the patterns on the drawing and explaining to the girls the purpose of each pattern.

"It turns out that this is the case, but we can also use fire sugar to increase the temperature of the room."Yanhua said puzzled.

Because she thought that the fire pit burning in the middle could also increase the temperature. Why do we have to do such a troublesome thing?

"If you use a fire pit, you need to use wood, and when the wood is burned, it will produce charcoal, and then burning the charcoal will produce carbon monoxide, and this carbon monoxide is poisonous, which will threaten our life safety."Su Bai explained seriously.

"Carbon monoxide? Poisoned? Although Yanhua had never heard of carbon monoxide, she knew that poisoning was a trivial matter and said in surprise:"Then it seems that this is very unsafe."".........................................
