Doomsday Bunker Upgrade

Although Chen Xin has transformed his greenhouse from ordinary soil planting to one where hydroponics and soil planting can be carried out at the same time, and has also added a comprehensive three-dimensional aquaculture planting system such as fish culture in water, this experience is more suitable for small plants. Large-scale greenhouses, for large-scale greenhouses, at least for this planting greenhouse in the village, the experience cannot be copied.

This is also very understandable. Chen Xin's greenhouse has a small area and is relatively simple to transform. Even if hydroponic cultivation and water body aquaculture are added, in terms of cost and investment, there is no need to add too much, just add some things. implement his ideas.

This is also known as the so-called small boat, but for a larger greenhouse, this is not easy to achieve.

Not to mention, the area of ​​this greenhouse in the village is nine times that of Chen Xin's original greenhouse. If hydroponic cultivation is carried out, the corresponding increase in investment and cost will be at least ten times, or even more.

The increase in area is not only the accumulation of unit cost, but also needs to increase other costs.

Whether it's Chen Xin or the second uncle, these are things that must be carefully considered, and you can't make a decision directly.

And how to transform it is also something that needs to be considered. The area of ​​the greenhouse is nine times larger. It is not like Chen Xin's greenhouse, just put up a shelf and set up the hydroponic planting tank and it will be done.

The circulation of the water body in the hydroponic tank, the erection of the fill light and the circuit wiring, the erection of the hydroponic planting tank... There are too many things to consider.

However, compared with the many considerations for the planting greenhouse, it cannot be upgraded immediately. After Chen Xin solved the power problem in the shelter, the change brought about by the heating equipment that was finally opened was immediate.

Although the original shelter had a certain thermal insulation effect, the temperature was always very low, and everyone had to wear thick padded jackets to protect against the cold even indoors. The reason, after all, in order to ensure that the chickens can lay eggs normally, they have a heater to bake the fire, and people really can only keep warm and shake.

Fortunately, as the heater was turned on, the temperature in the shelter has risen significantly. At least everyone's pale complexion due to the low temperature has returned to a ruddy blood color, so they don't look like they have white powder on their faces. Same.

Although low temperature does not directly cause frostbite to the human body like severe cold, long-term exposure to a low temperature environment will still cause considerable damage to the human body. This damage is not only reflected in the grayness of the complexion.

Even in terms of damage to health, the damage suffered by the human body in a long-term low temperature environment is greater than that of frostbite.

Although both of them can cause death in seriousness, it is just that one dies quickly and the other dies slowly.

In fact, for the vast majority of survivors in shelters today, hypothermia caused by low temperature is a problem they have to face. Insufficient food, shortage of heating, various factors, and hypothermia are not a problem. The damage is as obvious as frostbite. It can be said that the number of people suffering from hypothermia is much higher than the number of frostbite.

Therefore, Chen Xin was able to make the heating equipment in the refuge run, which has a far greater impact on the entire refuge than other things.

In order to ensure that there are no other problems, Chen Xin also specially went to the computer room where the heater was installed with his father, and checked the heating equipment. Naturally, Chen Xin also wanted to see what kind of enemy law the heating equipment could be upgraded.

"The cooling capacity is 140KW? The power of this central air conditioner is not too big." Chen Xin looked at the nameplate on the equipment in front of him and was not satisfied with the output power.

"It's enough. Generally, hotels or office buildings use this kind of central air conditioner. At most, a few more units are connected in parallel." Chen Xin's father didn't care much about it, and even said it as a joke to Chen Xin. One sentence: "Do you think that central air conditioners are like circulating water cooling towers in factories, with a flow of thousands of tons? Small equipment does not have that much heat dissipation."

Chen Xin thought about it for a while, and it seems that this is indeed the case. After all, the related equipment he had been exposed to in his previous work was all large-scale equipment in the factory, such as the air-cooled cooling tower that uses circulating water as the cooling medium, even if the cooling capacity is only a few The heat dissipation capacity of a small cooling tower with a flow rate of 100 tons can reach several thousand kilowatts, which is really not comparable to this small central air conditioner.

"Then do you want to modify this equipment? Improve the output power?" Chen Xin asked his father. In his opinion, although the cooling capacity is not small, it is not satisfactory.

The temperature in the shelter is indeed much higher than before, but the temperature has only risen from 0 °C to a few °C, which is not satisfactory. Chen Xin feels that the output power can be increased a little more.

Regarding this question, Chen Xin's father hesitated for a while. After thinking about it, he asked Chen Xin: "How do you want to change it? How much do you invest? How much can the output power increase after the change? How much will the power consumption increase?"

As a manager who used to be in charge of the equipment of a large-scale state-owned chemical plant, Chen Xin's father had already developed a habit. When he heard Chen Xin mention the transformation, he directly asked a few key questions, and even almost wanted to let Chen Xin out. A feasibility report is out.

Chen Xin didn't find anything strange about his father's professional habits for many years, but after thinking about it, he replied: "Improve the operating efficiency of the equipment, increase the output power, and make the cooling capacity reach 200KW, and the increase in power consumption needs to be calculated. , should not exceed 30%.”

Of course, this is not the data that Chen Xin made up casually, but the conclusion he came to by observing the central air-conditioning unit in front of him with the help of the system's upgrade interface.

When Chen Xin's father heard him say this, he did not agree immediately, but continued to ask him: "It is a way to increase the output power, but what is the efficiency of converting the output power into cooling capacity? Has the efficiency improved or decreased?

You are only connected to a 150KW battery now. Whether it can meet the needs of the equipment after the transformation, and whether the entire circuit can withstand such a large load, you have to consider it, not just to improve the efficiency of the equipment. "

Chen Xin's father has too much experience in this kind of equipment transformation. He clearly knows that the transformation of a piece of equipment is not simply to improve the output power of the equipment.

In his many years of work experience, he has encountered too many transformation cases where the data on the surface looks very good, but the actual transformation cannot achieve the expected effect. Therefore, Chen Xin wants to transform the heating equipment of the shelter. He couldn't help but want to ask a few more questions.

Chen Xin can of course understand his father's worries and concerns. Although these problems can be solved by relying on the system even if Chen Xin occurs, it is obviously better to think clearly about the problem before doing it than to solve the problem after the accident. appropriate.

So after listening to his father's question, Chen Xin also rearranged his thinking and let the system upgrade interface display a new upgrade plan, and then explained to his father in detail how he planned to transform.

After listening to Chen Xin's explanation, Chen Xin's father thought about it and said, "You can change it this way, but I still recommend that you adjust the circuit first to ensure that the circuit can withstand such a large load, and then move the equipment to avoid the occurrence of question."

"I know, this is not urgent, and the transformation also requires materials, and I have to ask the second uncle's opinion before he agrees to start the transformation." Chen Xin did not have the idea of ​​accepting it all immediately.

Seeing that Chen Xin had already made up his mind, his father didn't say anything more, just nodded to him: "You can just make up your mind."

——————————————————

Of course, the shelters in the village can be transformed not only in three aspects: electrical circuits, heating and greenhouses, but after careful consideration, Chen Xin asked his father and the second uncle himself for their opinions. transformation in these three aspects.

Other places in the shelter can also be renovated and upgraded, but compared with these three aspects, the transformation and upgrading of other aspects are not urgent, and the improvement and improvement of the quality of life are not so obvious.

Although for Chen Xin, as long as there is an improvement and improvement in the quality of life, he can gain survival points, but in the second uncle and the others, there is no need to transform and upgrade where it is not necessary.

The second uncle is in favor of the transformation of circuits, heating and greenhouses, but for other aspects of the transformation, because the improvement of the quality of life is not so obvious, in the second uncle's view, this is a bit wasteful and extravagant. behavior.

After all, Chen Xin did not use the method of directly smashing the survival points to upgrade. All the transformations required the second uncle to use the vegetables produced in the greenhouse to exchange the materials for the upgrade in the town. He obviously needed to consider the cost of the transformation.

Chen Xin can also understand this, so he has no opinion that the second uncle only intends to reform in three aspects.

Moreover, Chen Xin's original intention was mainly to improve the quality of life for his relatives at home, because helping relatives to improve the quality of life and obtaining survival points were just an expected extra gain for Chen Xin.

Therefore, in this matter, Chen Xin still fully respects the opinions of the second uncle and the others. Since they decided to improve only the circuit, heating and greenhouse, Chen Xin will naturally not be too busy.

After it was determined that only the three aspects of the circuit, heating and greenhouse were to be modified, Chen Xin also made a list of the materials needed for the transformation and handed it to the second uncle. The second uncle also promised to go to the town as soon as possible to collect the materials. together.

It's the end of the month, ask for a monthly pass! Without a monthly pass, the idea is not smooth.
