Chapter 130

The rekindling of old love between old lovers is only an episode after all. How to survive is the theme of this doomsday.

For Chen Xin, he no longer has to worry about how to survive.

The emergence of hot spring water greatly improves the heat energy that can be obtained by ground source heat pump. Even if Chen Xin turns off the equipment, the temperature in the shelter can be maintained at about 13 ~ 16 ℃ due to the influence of groundwater heating.

If it is not necessary to maintain the temperature of the greenhouse, the ground source heat pump just made by Chen Xincai is even redundant.

But it also gave him a new idea, that is to use the heat generated by ground source heat pump to generate electricity.

This is not difficult to achieve in technology, just need to connect a heat recovery device on the radiator, and then use the heat to carry out heat conversion, and convert it into electric energy.

As for the means of transforming heat energy into electricity, steam turbines commonly used in thermal power plants are enough to complete the task.

When it comes to steam turbines, Chen Xin used to be a geek fan for a while when he was in college. In his dorm room, he used air cushion bed blowers and discarded CDs to transform a Tesla turbine that could really turn light bulbs into electricity.

Although it has no practical significance at all, it depends entirely on the blower to drive the impeller to rotate and work, but on the whole, the thing is made, and it is not complicated to make it. Chen Xin's computer still has drawings he used at that time.

Tesla turbine is a turbine invented by legendary federal physicist Nicolas Tesla.

This turbine is much more efficient than the traditional blade turbine, and Nikola Tesla once dreamed of using it to generate electricity from geothermal energy.

Of course, although this technology looks very beautiful, it is still restricted by many conditions in practical application, so that this technology has been invented by Nikolay Tesla for more than 100 years, and its practical application is still very few.

The main reason that restricts the popularization and application of this technology is that the inner rotor must be arranged in a compact way with disks that are thin enough and smooth enough to form a large enough rotor. Only in this way can the rotor be driven to rotate at high speed by the fluid passing through the rotor under the action of boundary layer effect.

There is no doubt that the material for making the disc is highly required, which is not only light but also strong.

Moreover, the bladeless turbine has a big problem, that is, the higher the load, the lower the efficiency. In order to achieve a high enough speed, the fluid flow through the rotor must be as small as possible.

However, this is not a problem for Chen Xin.

With the help of the system, the production of the rotor is not a problem at all, and what Chen Xin needs is only a small generator that can meet the power demand of his refuge. Neither the load nor the fluid flow is too large.

"Xin, what are you doing?" Qin LAN watched Chen Xin continuously process a piece of metal material into a thin circular metal sheet on the workbench. She couldn't help but feel very curious.

"To be a turbine, I'm going to use the surplus heat of GSHP to generate electricity. I need a turbine." Hearing Qin Lan's inquiry, Chen Xin explained to her at the same time, did not stop the work in hand.

In fact, Chen Xin is not processing these round metal pieces himself, but in Qin Lan's eyes, Chen Xin is processing them himself.

With the help of the system, the metal materials are processed into thin paper like metal discs and assembled, and then the main shaft is installed in the middle, and the rotor of the bladeless turbine is finished.

Qin LAN looks at Chen Xin's serious work and doesn't disturb him. She just leans on Chen Xin's desk and watches him work quietly.

There is a saying that the man who works hard is the most handsome. At this time, Qin Lan's eyes to Chen Xin undoubtedly confirm this sentence.

However, Chen Xin did not notice that Qin Lan's eyes were full of infatuation. He just installed the assembled rotor into the volute.

After assembling the whole turbine casing and checking that there was no problem, Chen Xin turned the rotor by hand again and confirmed that the rotor was running normally by manual turning. Then he connected the whole volute to the gearbox.

Although the speed of Vaneless turbine is high, the torque is not big. In order to obtain enough output power, it is necessary to reduce the speed of gearbox to improve the torque of transmission shaft.

This is not a complicated process, a set of planetary gears can solve the problem.

As for the generator part is more simple, cutting magnetic induction line power generation principle even junior high school students understand.

After all the parts are assembled and a generator connected to a bladeless turbine is ready, the next step is naturally installation.

"Alan, help me carry it over." The generator is a little heavy, so Chen Xin has to ask Qin LAN to help him.

Two people will lift the generator to the side of the ground source heat pump, put down the generator, Qin LAN curiously asked: "where should this be installed?"

"Just connect the pipe to the condenser. When the air flow in the pipe passes through the condenser, it can absorb the heat emitted by the condenser, so as to expand the air volume and form high-speed air flow to drive the rotor of the turbine." Chen Xin explained that he opened the system interface and chose to consume the survival point to install the device.The installation of the system is much more convenient than Chen Xin's own manual installation. He even helped him to run the line well and connect the generator to the distribution room.

As Chen Xin adjusted the output power of the ground source heat pump and turned on the switch of the turbine, the generator started to run.

"It's really moving!" Looking at the turbine and generator that Chen Xin received from the condenser, Qin LAN couldn't help but exclaim: "ah Xin, you are so powerful!"

"People who know a little bit about machining and physics can do this. It's nothing." Chen Xin shook his head. He didn't feel proud of Qin Lan's praise: "if it wasn't for the rise of ground temperature caused by underground hot springs, the power generation capacity of this system would be enough to maintain the operation of ground source heat pump equipment.

But now the ground temperature rises, the excess heat energy can be converted into more electric energy. As long as the power of the generator is a little higher, it should be able to maintain the power consumption here.

Now I'm only worried that the rise of underground water temperature is temporary. When the broken underground water layer is blocked again and the low temperature drops... "

At this point, Chen Xin could not help showing a little worried expression.

"Ah Xin, you are too pessimistic. If you think about it better, maybe it will be permanent? You'll have hot springs in the future. " Qin LAN smiles and encourages Chen Xin to be optimistic.
