Not to mention the current era.

Even in the Hereafter.

When the air conditioner is turned on, the cooling effect is not so awesome.

If you encounter a large space, you can't completely cool it when you turn on the air conditioner.

At this moment, I glanced at the area of this palace, the area inside the palace is indeed a little large, which is normal, and the palace was built in the Qin and Han dynasties.

The area of a palace is as large as a shopping mall in later generations.

With such a large space, it is really difficult to rely on ice cubes for cooling.

So after a slight hesitation, Ying Changsheng thought for a while, and then opened his mouth to say.

"That's it, this son has researched a refrigerated baby!"

Well, Win Changsheng is planning to research things to refrigerate.

What is the best way to refrigerate? Of course, the fan is the most suitable, and the technical content is also the simplest.

First of all, you can make a few fan blades, as for how to get the power of the fan?

Of course, Ying Changsheng had already thought about it, it was impossible for him to use the steam engine as the power of the fan.

The steam engine needs to be heated to be able to produce heat, and the heat generated by the steam engine is much stronger than the effect of refrigeration.

At this moment, I saw Ying Changsheng hurriedly say goodbye to Ying Zheng, and then went to the craftsman to prepare to make his own refrigeration equipment, and the fan power it uses is actually very simple.

That is to do it by manpower to make the fan rotate.

Well, only by manpower, in this day and age.

It's too hard to get other motivation.

After all.

In this era, it was too difficult to develop a motor, and even if it was a motor, it had no voltage and could only be generated by a hand-cranked generator.

In this case, in the end, it is still powered by manpower, which is simply taking off your pants and farting, and this is an extra move.

Therefore, it is better to directly use manpower as the power of the fan at the beginning.

Of course, it is impossible for Ying Changsheng to just make a fan, because the wind blown by the fan is actually hot in a sultry environment.

After blowing on the person's body.

There is not much, the feeling of coolness, and I will feel a headache after blowing too much.

Win immortality in such a situation.

Naturally, it was going to be transformed, and the fan he made had to be used in combination with one thing, and that was ice.

It is to make a wooden frame in front of the fan, then fill it with ice cubes, and then turn the fan so that the fan blows out a cool breeze.

This thing was popularized and used in later generations.

It was used as an earthen air conditioner in the early days when productivity was not well developed.

The effect is not bad.

As the core component of the earth air conditioner.

The most central thing in it is nothing else, which is the fan blades.

Ying Changsheng plans to use brass to cast directly, because this can be mass-produced, and only need to make a good mold, and the shape of the fan blade is finalized by him himself.

During the Qin Dynasty, it was used for casting precision instruments.

is still very proficient, and at this moment, with the order of Ying Changsheng.

The craftsmen next to him hurriedly made it, and after the mold, they quickly completed the casting with the bronze, and cast the fan blades of the three fans, which Ying Changsheng was very satisfied with.

He went into action again, prepared the bearings, mounted them on the irons, and randomly fixed the fan blades to the frame above the bearings.

In this way, a simple fan is made.

Of course, the power of this fan has not been solved yet.

The way to win Changsheng to provide him with motivation is very simple.

That is to make a pull cord on the side of the fan, and then wrap it around the fan, as long as you pull the rope, you can turn the fan, the faster you pull, the faster the fan will rotate.

In addition to this, it will install a rope roller on the left and right sides.

And so on.

It can be pulled back and forth by two people, so that this fan can blow out a steady stream of cool breeze.

For this matter, Ying Changsheng doesn't feel that there is anything bad for the reason is very simple.

It's not a tiring job, it's a very easy job.

Secondly, the palace maids in Xianyang Palace, so casually find a few to work in turns, wouldn't it be easy.

It is easy to make this fan run for a long time.

In addition, the palace maids can also experience the coolness while maintaining the operation of the fan.

At this moment, Ying Changsheng felt that his idea was simply good, and he made a framework again, and then a homemade airdrop was successful, and it was produced.

The principle is very simple, and the production is very simple.

A palace only needs to install a dozen such air conditioners, which can keep the palace cool at all times, and there are gusts of cool breeze.

At this moment, Ying Changsheng quickly made an attempt.

He directly loaded the frame with a bucket of ice in the tin bucket, and then ordered the two workers to pull the rope back and forth to drive the fan inside.

I only saw the cold air in the ice cubes in the frame blowing under the rotation of the fan, and for a while, the cool breeze hit and won the Long March, and I felt very comfortable, and I could still feel the cool wind from a distance of several meters.

Seeing this, a smile appeared on Ying Changsheng's face.

He said with a smile on his face.

"Not bad, take this thing to Xianyang Palace immediately, and then my son wants to let my father also taste the joy of this air conditioner!"

"No!"

Ying Changsheng's voice fell.

For a while, the workers next to them didn't dare to slack off in the slightest, they hurried and took action, and then under the command of Ying Changsheng, they carried this air conditioner and left here.

Inside the Xianyang Palace, Ying Zheng frowned, and was reviewing the folds, with fine sweat on his forehead.

Although there is ice next to it to cool down, the effect is really not very good, so Ying Zheng still feels a burst of sultry heat hitting him, and he feels a little uncomfortable.

Just then, a sound of footsteps came in from outside.

I saw Win Changsheng, and strode in with a smile, and when I saw my son coming in, I couldn't help but look at Win Changsheng.

Then he opened his mouth with a smile and asked.

"What are you trying to do here?"

"Father, do you think it's hot here?"

Ying Changsheng smiled and asked Ying Zheng.

After Ying Zheng heard this, he inevitably rolled his eyes, and then said to Ying Changsheng in front of him.

"Of course it's hot, it's really hot in this palace, but then again, isn't that the case in summer?"

Ying Zheng's voice fell, and Ying Changsheng said to Ying Zheng with a smile.

"Erchen has a little good thing that can make your old man no longer suffer from the heat!"

"What's that?"

Hearing that he won politics here, his eyes suddenly lit up.
