Chapter 252: Father's consideration

"I can upgrade the refuge novel ( to find the latest chapter!
Although Chen Xin has transformed his own greenhouse from ordinary soil planting to hydroponic and soil planting at the same time, and added a comprehensive three-dimensional aquaculture planting system such as aquaculture fish, this experience is more suitable for small Large-scale greenhouses, for large-scale greenhouses, at least for the planting greenhouses in the village, experience cannot be copied mechanically.
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 a few things. Realize his ideas.
This is the so-called small boat turning around, but for larger greenhouses, 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 planting 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 other costs.
Whether it is Chen Xin or the second uncle, these are things that must be carefully considered, and you can't just make a decision with your head.
And 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 built up with a shelf.
The circulation of the water body in the hydroponic tank, the installation of the supplementary light and the wiring of the circuit, the erection of the hydroponic planting tank...There are too many things to consider.
However, compared with the many considerations for planting greenhouses, it cannot be upgraded immediately. After Chen Xin solved the power problem in the refuge, the changes brought about by the heating equipment finally turned on were immediate.
Although the original refuge has a certain thermal insulation effect, the temperature has always been very low. Everyone must wear a thick padded jacket to resist the cold even when indoors. This is why the second aunt will tell Chen Xin that people are not as good as chickens. The reason, after all, in order to ensure that chickens can lay eggs normally, they have a heater to heat the fire, so people really can only keep warm by shaking.
Fortunately, as the heater is turned on, the temperature in the refuge has risen a lot, at least everyone’s pale face due to the low temperature has returned to ruddy blood, so that they don’t look like 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 low temperature will still cause serious damage to the human body. This damage is not only reflected in the gray complexion.
Even in terms of damage to health, the damage to the human body in a long-term low temperature environment is greater than that of frostbite.
Although both of them can cause death when they are serious, it's just that one dies quickly and the other dies slowly.
In fact, for most of the survivors in refuges today, hypothermia caused by low temperature is a problem they must face. Insufficient food, shortage of heating, various factors, and hypothermia are not 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 people suffering from frostbite.
Therefore, Chen Xin is able to make the heating equipment in the shelter run, and the impact on the entire shelter is far greater than other things.
In order to make sure that there are no other problems, Chen Xin deliberately 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 could be upgraded.
"The cooling capacity is 140KW? The power of this central air conditioner doesn't feel great." 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 type of central air conditioner, and at most several units are connected in parallel." Chen Xin's father didn't care much about it, and even said to Chen Xin like a joke. One sentence: "Do you think that central air conditioners are like circulating water cooling towers in factories, with a flow 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 air-cooled cooling tower that uses circulating water as the cooling medium has only a few cooling capacity. The heat dissipation capacity of a small cooling tower with a flow rate of 100 tons can reach several 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 really not satisfactory. Chen Xin feels that the output power can be increased a bit.
Regarding this question, Chen Xin's father hesitated for a while, and thought about it and asked Chen Xin: "How do you want to change? How much do you put in, how much output power can be increased after the change? How much power consumption will increase?"
As a manager in charge of large-scale state-owned chemical plant equipment, Chen Xin’s father has long developed a habit. Hearing Chen Xin mentions transformation, he directly asked a few key questions, and even almost wanted Chen Xin to come out. A feasibility report is out.
Regarding his father’s many years of occupational habits, Chen Xin didn’t find it strange, but after thinking about it, he replied:
Improve the operating efficiency of the equipment, increase the output power, and let the cooling capacity reach 200KW. The increase in power consumption requires calculation. , It should not exceed 30%."
Of course, this is not the data that Chen Xin compiled casually, but the conclusion he reached after observing the external unit of the central air conditioner with the help of the system 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? Is the efficiency improved or lowered?
You just connected 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 really had too much experience in this kind of equipment modification. He clearly knew that the modification of a piece of equipment was not simply a matter of increasing the output power of the equipment.
In his years of work experience, he has encountered too many transformation cases where the data on the surface looks very good, but after the actual transformation, the expected effect cannot be achieved, so for Chen Xin's idea to transform the heating equipment of the refuge He couldn't help but wanted to ask a few more questions.
Of course, Chen Xin understands these worries and worries of his father. Although Chen Xin can solve these problems by relying on the system, it is obviously better to think about the problems before you start to solve them than to solve them after an accident. Appropriate.
So after listening to his father's question, Chen Xin also reorganized his thoughts and made the system upgrade interface show the new upgrade plan. Only then did he explain 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 suggest you adjust the circuit first to ensure that the circuit can withstand such a large load before moving the equipment to prevent it from appearing. problem."
"I know that this is not a hurry, and the transformation also requires materials. I have to ask the second uncle's opinion, and he agreed to start the transformation." Chen Xin did not have the idea of ​​accepting everything right away.
Seeing that Chen Xin had already thought about it, his father didn't say much, but just nodded to him: "Just think about it."

Of course, the village’s refuge can be renovated beyond the three aspects of electrical circuits, heating and greenhouses. However, after Chen Xin carefully considered and asked his father and the second uncle himself for their opinions, Chen Xin decided to just These three aspects are transformed.
Other places in the shelter can also be upgraded, but compared to these three aspects, other aspects of the upgrade 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, it is unnecessary to transform and upgrade.
Regarding the three aspects of electrical, heating and greenhouse renovation, the second uncle is in favor, 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 wasteful and extravagant. Behaved.
After all, Chen Xin did not use the method of directly smashing survival points to upgrade ~ EbookFREE.me~ All the renovations require the second uncle to use the vegetables produced in the greenhouse to go to the town to exchange the materials used for the upgrade. He obviously needs Consider the cost of transformation.
Chen Xin can also understand this, so he doesn't have any opinions about the second uncle's plan to reform only three aspects.
Moreover, Chen Xin's original intention was mainly to improve the quality of life for the relatives at home, because helping relatives to improve the quality of life and gaining a survival point was nothing but an expected extra gain for Chen Xin.
So on 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 electric circuit, heating and greenhouse, Chen Xin will naturally not be troublesome.
After confirming that only the three aspects of the electric circuit, heating and greenhouse were to be renovated, Chen Xin also made a list of the materials needed for the renovation and gave it to the second uncle. The second uncle also promised to go to the town to collect the materials as soon as possible. Qi.
