"I Can Upgrade Vault Novels()" Find the latest chapter!
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 water fish culture, but this experience is even more It is suitable for small-scale greenhouses. For large-scale greenhouses, at least for this planting greenhouse in the village, the experience cannot be copied.
This is also easy to understand. Chenxin’s greenhouse is small and relatively simple to transform. Even if hydroponic planting and aquaculture are added, there is no need to increase much in terms of cost and investment, just add some Something can make his idea come true.
This is also known as a small boat, but for larger greenhouses, this is not easy to achieve.
Let's not mention anything else, the area of this greenhouse in the village is nine times the area 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 is for Chen Xin or for the second uncle, these are things that must be carefully considered and cannot be decided directly.
Moreover, how to transform is also something that needs to be considered. If the greenhouse area is nine times larger, it is not like Chen Xin's greenhouse, and the hydroponic planting trough is set up on a shelf.
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 to 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 finally opened up 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. This is why Eryi told Chen Xin that It's not as good as chickens. After all, in order to ensure that chickens can lay eggs normally, they have heaters to roast them, 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 ruddy blood, so that each one does not look like a face Like white powder.
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 serious damage to the human body, and 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 be fatal in seriousness, one dies quickly and the other dies slowly.
In fact, for most of the survivors in shelters today, hypothermia caused by low temperature is a problem they have to face. The lack of food, the shortage of heating, the influence of various factors, and the low temperature It can be said that the number of people suffering from hypothermia is much higher than that of frostbite.
So Chen Xin was able to make the heating equipment in the Refuge work, which had a far greater impact on the entire Refuge than anything else.
In order to ensure that there are no other problems, Chen Xin also went to the computer room where the heater was installed with his father, and checked the heating equipment. Naturally, Chen Xin also wanted to check the heating equipment to see what anti-methods can 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.
"Enough is 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 joked with Chen Xin. He said: "Do you think that the central air conditioner is like a circulating water cooling tower in a factory, with a flow rate of several thousand tons? Small equipment does not have that much heat dissipation."
Chen Xin thought for a while, and it seems that this is indeed the case. After all, the related equipment he has come into contact with in his previous work are all large-scale equipment in the factory. The heat dissipation capacity of small cooling towers with only a few hundred tons of flow can reach several thousand kilowatts, which is really not comparable to this small central air conditioner.
"Would you like to modify this equipment? Increase the output power?" Chen Xin asked his father. In his opinion, the cooling capacity is not small, but it is not satisfactory. .
The temperature in the refuge is indeed much higher than before, but the temperature has only risen from 0°C to a few°C, which is not a satisfactory level. Chen Xin feels that the output power can be increased a little bit.
For this question, Chen Xin's father hesitated for a while, and asked Chen Xin after thinking about it: "How do you want to change it? /
As a manager who used to be in charge of the equipment of a large 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 Chen Xin issued a feasibility report.
Chen Xin didn't find anything strange about his father's work habits for many years. He just thought about it and replied: "Improve the operating efficiency of the equipment, increase the output power, make the cooling capacity reach 200KW, and consume electricity. The increase needs to be calculated and should not exceed 30%.”
This is of course 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 immediately agree, but continued to ask him: “Improving output power is one way, but what is the efficiency of converting output power into cooling capacity? Has some work efficiency improved or decreased?
You are only connected to a 150KW battery. After the transformation, whether it can meet the working needs of the equipment, and whether the entire circuit can withstand such a large load, you have to consider, 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 just a matter of increasing the output power of the equipment.
In his years of work experience, he has encountered too many cases where the data on the surface looks very good, but after the actual renovation, the expected effect cannot be achieved, so for Chen Xin he wants to renovate the refuge heating He couldn't help but want to ask a few more questions about the idea of equipment.
Chen Xin can of course understand his father's worries and concerns. Although Chen Xin can solve these problems even if they occur by relying on the system, he obviously solves the problem before he starts doing it, rather than solving the problem after the accident. It is more appropriate to think clearly.
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 line can withstand such a large load before moving the equipment. , to avoid problems."
"I know, this is not urgent, and the transformation also requires materials. I have to ask the second uncle's opinion, and he agrees to start the transformation." Chen Xin did not have the idea of accepting everything right away.
Seeing that Chen Xin has 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 Chen Xin carefully considered it and asked his father and his second uncle for their opinions, Chen Xin still It was decided that only these three aspects should be revamped.
Other parts of the shelter can also be renovated and upgraded, but compared with these three aspects, the renovation 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 approves of the three aspects of electrical circuit, heating and greenhouse renovation, but for other aspects of the renovation, because the improvement of the quality of life is not so obvious, in the second uncle’s view, this is a bit of a waste and extravagant behavior.
After all, Chen Xin did not use the method of directly smashing the survival points to upgrade~IndoMTL.com~ 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 The cost of retrofitting needs to be considered.
Chen Xin can also understand this, so he has no opinion that the second uncle only intends to reform in three aspects.
Furthermore, Chen Xin's original intention was mainly to improve the quality of life for relatives at home, because helping relatives to improve their quality of life and gain a survival point is nothing but an expected extra gain for Chen Xin.
So in this matter, Chen Xin still fully respects the opinions of the second uncle and the others. Since they decided to improve only the three aspects of the circuit, heating and greenhouse, Chen Xin will naturally not be too busy.
After confirming that only the three aspects of electric circuit, heating and greenhouses should be renovated, Chen Xin also made a list of the materials needed for the renovation and gave it to the second uncle, who also promised to go to town as soon as possible. Gather the materials together.
