'How does the refrigerator depressurize high-temperature and high-pressure liquids....'

'When I was a child, when I was playing with water, if I opened the valve and blocked part of the pipe with my fingers... The pressure difference between the inside and outside will make the water splash out.... This process should also be considered 'depressurization', right? ’

So, by 'throttling', can you achieve depressurization? Well, let's call it a 'pressure down valve'....'

Therefore, the process should be: low temperature and low pressure steam - compression zone - high temperature and high pressure steam - heat dissipation zone - medium temperature and high pressure liquid - pressure relief valve - low temperature and low pressure semi-liquid semi-steam - refrigeration zone - low temperature and low pressure steam - compression zone, that is, compression/condensation/depressurization/evaporation, four refrigeration cycle processes. ’

'In addition, there is refrigerant .... What is it called freon? It still seems to be outdated, and I only remember the name...'

Let's think about what kind of properties the refrigerant should have. ’

First of all, the chemical properties should be stable, preferably non-toxic and non-corrosive; ’

Secondly, considering the volume of the compression zone, the refrigerant refrigeration capacity per unit volume should be relatively high; ’

Thirdly, the density should be small to reduce the working loss in the compression zone; ’

Finally, the ability to conduct and dissipate heat should be high. ’

‘em.... It doesn't feel like it's working, and now it's easy to get your hands on water.... Did you use water as a refrigerant in your previous life? By the way, carbon dioxide can also be obtained relatively easily..... If you can solve other problems, let's use these two experiments first. ’

'Compression zone, let me think about what the working state should be....'

Bladetooth quickly entered meditation and began to visualize in his mind how the compression zone would work.

'The compressor is the most complex, a rectangular cylinder, a wall-attached compression piston, and two inlet and outlet ports above it......

'Throttle valve, hourglass pipe plus capillary, should be fine...'

'The heat dissipation condensation sheet is a bit difficult, and the thermal conductivity has to be considered; The shape is simple, isn't it just a fence? ’

'The evaporative cooler and the heat dissipation condensate should be similar, and the thermal conductivity must also be considered. ’

In meditation, except for the 'compressor' part, which is too complicated and only has a rough idea, the other parts are basically logically self-consistent.

Returning from meditation, recalling the 'refrigeration cycle' that had been simulated in his mind earlier, Blade Fang whispered,

"Materials and energy.... That's the biggest obstacle. ”

"There are no metal mines, no rubber, not even the most basic steam engine, let alone anything else."

Just then, a knock on the door interrupted his train of thought, and Bladetooth opened the door in confusion and looked out.

Standing outside the door were two big witch doctors and middle witch doctors with tired faces.

"The two witch doctors are back? Didn't get hurt, did you? ”

"It's not hurt, it's just that the beast is too cunning, and it took us too much energy to catch it."

The witch doctor dusted off his body and complained.

"It's not a big deal, do you want to come and see it? Haven't seen a blade-toothed beast yet? ”

The Great Witch Doctor seemed to have been told something by the Chinese Witch Doctor, carefully observed the mental state of Blade Fang, and carefully invited.

"Okay, let's go take a look."

Blade Fang, who had never crawled out of the bottleneck, did not refuse the witch doctor's kindness, and followed directly.

，，，，，，，，

Bladetooth, kept in a square container covered in hides.

By the time they arrived, they had been moved to the entrance to the basement not far from the Witch Doctor's compound.

Looking at the appearance of the soldiers at the moment, it seems that they are planning to lock them in the basement with the containers.

The only old witch doctor who was present before seemed to have just cast a spell to widen the entrance to the basement, and at this moment he was blessing the warriors in charge of carrying low-level strength, stamina and other buffs.

Seeing Bladetooth coming, the old witch doctor pointed to the half-room-sized container and said,

"Smooth the base so they can push it in."

Blade Fang nodded, used a spell to make the bottom of the cage extremely smooth, and then stepped forward and reached out to touch it, feeling that it was on par with the ice surface, and then he was satisfied.

Here, movement in the cage can already be faintly heard.

He cautiously reached out, lifted the fur that covered him, and glanced in the light.

What caught his eye was a beast that was more similar to the saber-toothed tiger in his previous life, but now he was trapped by the vines and seemed to be stunned, and he was snoring and falling asleep without domineering.

"Vines...."

The moment he saw the saber-toothed tiger, Blade Fang didn't feel too much shock, even if it was a super monster with his chest height and a tail body up to four meters, at this moment, it didn't seem to be as attractive as the thought that crossed his mind when he saw the vines.

Blade Fang immediately put down the fur in his hand and said only one word

"I thought of something, so I'll go back first." Then he turned and hurried away.

The three witch doctors sighed worriedly, but they didn't persuade much, just left to continue the unfinished work silently.

Hurriedly returning to the meditation room, Blade Tooth couldn't wait, and began to sort out the thoughts that had just flashed.

"Vines... Material... Spell... photosynthesis..."

He bowed down, his palms to the ground, and said,

"Mana transformation, plant synthesis preparation; starting position, three centimeters in front of the palm; Standard specification molding, target toughness 130%, hardness 120% preparation; Forward, standard speed extension ready ......"

At the end of the chanting, under the interaction between the inside and outside, a vine broke through the ground at a slow speed and stretched out in the predetermined direction.

Bladetooth scooped it into his hand and slowly felt the various properties of the vine.

"After the vine spell is cast, the vine will break out of the ground, and we can control its growth rate, growth direction, and even the hardness and toughness of the vine according to the needs of the spell."

"Plants are the most direct users of solar energy in the simple perception....."

"The reason why our 'plant-based' spells can grow rapidly is that in a certain rune group, we can definitely split out 'photosynthesis'-related runes..."

"In the same way, the manipulation of toughness, hardness, etc., can also indicate that in the 'shaping' stage, there are related rune groups that are hidden.."

"If we can dig out the details of the rune group related to photosynthesis, toughness, hardness, etc., instead of just using the 'plant shaping' rune group in general as it is now, then the refinement of the control will be greatly increased."

"The increase in finesse, once it exceeds a certain critical point, there are more things that can be done...."

"Photosynthesis power pool, hydraulic vapor compression system, leaf condensation and heat dissipation structure, plant vein depressurization hair detail flow channel, tree trunk cavity cooling chamber ....."

"As long as I can control all parts of the plant, from characteristics to appearance, grow to the way I need it, isn't that what a fully automatic plant refrigerator is?"

"And that's just the beginning, wood that conducts electricity, wood that can withstand high temperatures, wood that is harder than steel..... It seems that the plant industry can also be imagined? ”

"Yes, I was too obsessed with my previous life, and I was obviously obsessed with the rich treasure in front of me, so I wanted to cling to the methods of my previous life."

“.... It can't be said that if you don't think about your past life, how can you make efficient use of the 'treasure' you have here? ”

"Therefore, the two should complement each other, and the pursuit of knowledge from past lives must also be renewed."
