"Books, hehe, you ask me to learn this?"

Liu Lang's inquiry made Chen Chunsheng couldn't help but laugh.

"Two, you don't know, Professor Chen turned out to be an expert in this area, and no one in the domestic compressor field is more powerful than him!"

The other explained with a smile.

"Oh, is Professor Chen still engaged in this kind of research?"

Liu Lang asked again.

This time the other party fell silent.

"Alas, it's hard to put it into words! What's the matter? Liu Lang, you also know compressors?"

This time, Chen Chunsheng asked Liu Lang in turn.

"Haha, Liu Lang is a top student majoring in mechanical engineering at Huaxia University, what can.........'t he do? What a compressor, it's a fart in his eyes!"

Mu Xiaohu, who was sitting, also replied with a laugh.

"Huh, huh?"

Chen Chunsheng smiled, Liu Lang is a student of the engineering department of Huaxia University, he knows, but to say that the other party is proficient in compressors, it is a joke.

"Professor Chen, what kind of compressor do you have, can you make a refrigerator or an air conditioner?"

Liu Lang said.

"Oh, you know about refrigerators and air conditioners?"

This time Chen Chunsheng was a little surprised, these two kinds of electrical appliances are now very rare commodities on the market, ordinary people are married to be equipped with sewing machines, bicycles and watches, these three things are collectively called the necessary "three major pieces", refrigerators are not essential, and they can't afford to buy, the most general refrigerators also cost more than a thousand yuan, not to mention air conditioning, many people have never heard of it, the country does not have a factory to produce, all from imports, only high-level leaders will be equipped.

The core component of these two electrical appliances is the compressor, Liu Lang can know this level, obviously knows the compressor very well.

"We have a lot of good things in the mechanical college, not to mention the compressor of the air conditioner and refrigerator, and even the engine of the car. ”

Liu Lang said with a smile.

"Well, it looks like I'm really underestimating you......... Okay, I'll show you the good stuff!"

After Chen Chunsheng finished speaking, he stood up and came to a bookcase, took out a large roll of paper from it, put it on the table, unfolded it, and laid out a whole table.

"Do you know what this is?"

"I'll look at .........!"

Liu Lang took a closer look and immediately recognized it.

"This should be the Y-1959A model of strong wind compressor produced by our national compressor factory, completely imitating the compressor of the Soviet Union, and now our country still uses this model in many mines, the ability to pump air is very strong, but the noise is too loud, and people cannot stand within five meters. ”

This kind of compressor mechanical college has one, and it is difficult for Liu Lang to be difficult at all.

"Oh, yes, yes, I don't think you really know how to know compressors!"

This time was beyond Chen Chunsheng's expectations.

"Wait, look at this drawing again!"

Chen Chunsheng became interested, took out a key to open a locked cabinet, and took out another roll of drawings from inside.

"Check it out!"

Liu Lang looked at it carefully for a while.

"This compressor is much more advanced, at least much smaller in appearance, and can refrigerate, and can completely manufacture refrigerators, but the size is not small, if you make refrigerators, I am afraid you have to occupy two square meters of space, not applicable, not applicable!"

A refrigerator that occupies two square meters should be called cold storage.

"Awesome, awesome!"

Liu Lang's answer shocked everyone.

"Liu Lang, your mechanical academy also learns this kind of thing?"

The other asked curiously.

"Oh, Professor Xiong Huaizhi, the dean of our School of Mechanical Engineering, studied abroad, and went abroad after the reform and opening up, and knew a lot of machinery in western developed countries, he drew a lot of mechanical drawings after he came back, including a drawing of a refrigerator, their kind of compressor is much smaller, although the one you painted is very advanced in China, but put it in the world, it is very backward, not worth mentioning at all. ”

Liu Lang shook his head, obviously not interested in this thing.

"Xiong Huaizhi? I know him, he is indeed a capable person, but it's a pity......... You're right, I developed this compressor seven years ago, and it won a national award that year......... But I have one more good thing, if you can recognize it, I'll take it!"

After Chen Chunsheng finished speaking, he went upstairs, and after a few minutes, he took a roll of drawings and came down.

"Hehe, Lao Chen, you took out the things at the bottom of the box?"

The others said with a smile.

"Liu Lang, this little friend is an expert, it's nothing for our things to be seen by experts, it's just that there are too few experts like him, this drawing has been put for two years, and if you put it down, I'm afraid it will be spoiled by rats!"

Chen Chunsheng unfolded the drawings as he spoke.

"This is .........!"

Liu Lang looked at it carefully, this should also be a compressor, but it is much more complicated in terms of structure, and Liu Lang does not understand it very well in many places.

"You don't know now, do you?"

Chen Chunsheng said with some pride.

"This compressor is weird, this part should be......... It's supposed to be an exchanger, what about exchange? Refrigeration? No, it's not just refrigeration, it should theoretically be able to heat up......... Is it an air conditioning compressor?"

Liu Lang guessed.

"Ahh

Chen Chunsheng looked at Liu Lang as if he was looking at a monster.

"Professor Chen, you actually invented an air-conditioning compressor?"

Liu Lang was also surprised, with the air conditioning compressor, theoretically can be able to manufacture air conditioning, you must know that now there is no enterprise in the country can manufacture air conditioning, air conditioning companies will have to appear in a few years, among which the most famous enterprise "Meide" brand, this enterprise in the air conditioning manufacturing industry that is a well-deserved overlord in China.

"You're right, this is the air conditioning compressor that we people invented, and it took two years to develop, and the hard work was ......... Alas, without further ado, I'll explain it to you

This air conditioner can cool and heat, and the structure is divided into indoor unit and outdoor unit, and the most important part of the outdoor unit is the compressor. When we start the "refrigeration mode", the gaseous refrigerant in the compressor enters the outdoor exchanger and becomes a liquid, and then flows into the indoor exchanger through the pipeline, and then becomes a gas.

The "heating mode" is the opposite process, the gaseous refrigerant in the compressor enters the exchanger in the room, turns into a liquid, and releases heat, so that the room becomes hot.

Where does the liquid refrigerant go? It then flows through the pipe to the exchanger outside, becomes a gas, and then enters the room...... In short, it is a continuous cycle, so the air conditioner can continuously deliver cold or hot air to the room. ”

Speaking of this compressor, Chen Chunsheng couldn't stop, and explained the principles of refrigeration and heating clearly.

"I see!"

Liu Lang suddenly realized at this time, he originally thought that when the air conditioner was heating, the copper pipe was heated by electric energy, but it turned out that this was not the case, this was simply a control between temperature differences.
