I Was Reincarnated as a Commoner. I Can’t Stand Living Like This, so I’ll Become an Aristocrat! C171

171, Development of refrigeration equipment, Part 2

“Marcel-san, you’re amazing!”

"It's not that much of a compliment. You're really amazing. Besides, this is just a box that you can see inside. It's going to be difficult to keep it cool, right?"

"That's certainly true..."

If you put ice in this, it should get pretty cold, but you still have to go through the trouble of replacing the ice, and you wonder why you're replacing the ice in the store where there are customers in the first place. When the ice is replaced, the cold air inside escapes. 

In that case, would it be better to just pump in cold air without putting ice inside? I feel like it could be done by connecting something like a tube inside the case and allowing cold air to enter through that tube. 

“Marcel-san, instead of putting ice directly inside, how about just sending in cold air using wind magic?”

"Indeed...it might be better that way. It's just a matter of how we can create cold air..."

``For example, I connect a tube inside the case and make a box to put ice at the end of the tube.How about using wind magic to send cold air through that box?I think it will cool evenly evenly compared to putting ice directly in.'' Don’t you think so?”

When I said that, Marcel-san thought about it for a while and then nodded. 

"It might be good. In that case, it would be a good idea to make two tubes and circulate the air. I won't know until I try to make it."

"It may be a good idea to make two and circulate them. I'll try making them anyway!"

“Ah, first of all, transform the case you made earlier and make two tubes that connect the case and the box.Then, put wind magic into the magic stone, pass the tube from the case to the box, and from the box to the tube again. Please try to circulate the air back into the case. 

"Okay! I'll try it."

Then, I changed the magic iron again so that a magic iron tube would come out from the upper right side of the case, and I made a larger box at the end of that tube. Then pass the tube from the box to the lower left side of the case. The top of the box should have a zero-gap door to allow ice to be put in and taken out. 

And once the magic iron part is completed, I put wind magic into the magic stone. The wind magic adjusts the air volume and creates a magic that moves the air so that the cold air circulates throughout the case. Take in air from the bottom left side of the case and exhaust air from the top right side... 

Okay, perfect! 

"Marcel-san, you're here! Do you have an ice maker?"

"There is. Please put some magic in it."

"got it"

Then, I received the ice maker from Marcel and filled it with magical power to make ice. Then put the ice in the box you made earlier. 

All you have to do is fit the wind magic stone into the case... 

“I think this is perfect!”

"Okay, let's wait a while and see how cold it is."

Marcel-san said that and began to thoroughly observe the magic iron case I made. I will follow suit and observe the case. Is there anything that can be improved... 

“Leon, we also need equipment to drain the water when the ice melts.”

"Oh, I forgot. I'll make it for you."

　

I modified the magic iron a little so that the melted ice would gather in one place, and added a mechanism for the water to drain outside. Place a bucket under it for now. 

“Is there anything else you are concerned about?”

"No, I think it's done quite well. However, this doesn't solve the humidity problem. Also, there is a gap where the water drains."

That's certainly true. Even if you don't put ice directly in it, the ice melts and cold air flows in, so it's the same thing. Besides, you definitely need a place to drain the water... 

If I were to resolve this, what should I do? 

"That's true, but how can I resolve this?"

"I see..."

After saying that, we both thought about it for several minutes. Marcel was the first to speak. 

"Leon, I've got an idea! How about cooling the area around this tube? Wouldn't that also make the air inside colder?"

"Certainly...if the iron is cooled, the air will also be cold! If that's the case, the humidity won't increase."

"Is it cold inside the case now? Check the temperature and we'll make the next improvement."

"yes!"

Then, I opened the sliding door of the case and put my hand inside. Then, a cool breeze wafts in the air. 

"Wow... it's really cold. Cool..."

"Really?"

Marcel also came next to me and put his hand inside the case. 

　

"This... is good."

"Can't this be used not only to cool the case, but also to cool the room?"

"That's certainly true... If what we're going to try out turns out to be successful, we might be able to sell it just for its ability to cool the air."

“Is this current situation no good?”

“Oh, this is not much different from cooling a room with ice and a blower.”

“Indeed, that’s true.”

``Currently, it seems that the mainstream among aristocrats is to use ice and ice machines to cool their rooms.However, that method always comes with the problem of humidity.It cannot be used in places where there are books. If we can improve that, it will sell well.”

Was that so? The Royal School still only had blowers, so I didn't know about the air conditioning situation of the aristocrats. Summer, which is the hottest season, is a holiday. 

"Then, let's try a method of cooling the area around the tube!"

"I guess so."

Then, I improved the case again and tried a method of cooling the area around the tube with ice. The result was a huge success! We succeeded in cooling the inside of the case without increasing humidity. 

The next problem is condensation, but that can be solved using water magic, and I don't think it will be that much of a problem if you adjust the room temperature. Since this method was successful, it seems like we can make magic tools like air conditioners! 

"Marcel-san, I think we can use this at the store. Thank you so much!"

"I'm glad I was able to help."

“It’s really all thanks to Marcel!”

“It all depends on your ideas.”

"No, this time it's completely Marcel-san's fault. That's right, can we actually put some sweets in there and see what happens? I'll bring some sweets tomorrow."

"Good. Then why don't you leave this on the floor?"

"Certainly...this is a nuisance."

"It's not that much of a nuisance. Just put it on the floor and you'll be fine."

Even though something this big is definitely in the way... Marcel is such a nice person. 

"Thank you so much. Now let me put you down on the floor."

"Oh, can you hold it by yourself?"

"Of course, if you use physical strengthening, you'll have an easy victory."

I said that, strengthening my entire body, lifting the case and placing it on the floor. 

Physical strengthening is really useful when you have a large amount of magical power. It's scary how such a large case doesn't feel very heavy. Once you get used to this, you'll never train again, so I keep my use to a minimum. 

“Are you okay here?”

"Oh, good."

"Then I'll leave it there. Then I'll come back tomorrow!"

"Oh, I'll be waiting."

"thank you!"

With that, I left Marcel's workshop and returned home.
