    Although Chen Xin has renovated his own greenhouse, upgrading it from ordinary soil cultivation to one that can carry out hydroponics and soil cultivation at the same time, and has also added a comprehensive three-dimensional cultivation and cultivation system such as water fish farming, this experience is more suitable for small businesses.  For large-scale greenhouses, at least for this planting greenhouse in the village, experience cannot be applied mechanically.

    This is also easy to understand. Chen Xin¡¯s greenhouse is small and relatively simple to modify. Even if hydroponics and aquaculture are added, there is no need to add too much in terms of cost and investment. You only need to add a few things.  implement his ideas.

    This is the so-called small boat that can easily turn around, but for larger greenhouses, this is not easily achievable.

    ??????????????????????????????????????????????????????????????????????????

    The increase in area is not just the accumulation of unit costs, but also requires the increase of other costs.

    Whether it¡¯s for Chen Xin or for his second uncle, these are things that must be carefully considered, and decisions cannot be made directly.

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

    The circulation of water in the hydroponic tank, the installation of fill lights and circuit wiring, the installation method of the hydroponic planting tank there are too many things to consider.

    However, compared with the many considerations for the greenhouse, which cannot be upgraded immediately, the change brought about by the heating equipment that was finally turned on in the shelter after Chen Xin solved the power problem was immediate.

    Although the original shelter had a certain insulation effect, the temperature was always very low. Everyone had to wear thick cotton jackets to resist the cold even when they were indoors. This is why the second aunt told Chen Xin that people are worse than chickens.  The reason is, after all, in order to ensure that the chickens can lay eggs normally, they have heaters to keep them warm, so people really can only keep warm by shivering.

    Fortunately, with the heater turned on, the temperature in the shelter has obviously risen a lot. At least everyone's faces, which were a little gray due to the low temperature, have returned to their rosy color, and everyone does not 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 low temperature can still cause serious damage to the human body, and this damage is not only reflected in the grayish complexion.

    Even in terms of damage to health, the damage to the human body caused by long-term exposure to low temperature environments is greater than frostbite.

    Although both of them can cause death in severe cases, 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 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 can make the heating equipment in the shelter run, which has a far greater impact on the entire shelter than other things.

    In order to ensure that there were no other problems, Chen Xin and his father went to the computer room where the heater was installed and checked the heating equipment. Naturally, Chen Xin also wanted to see if there were any enemy methods that could be upgraded in the heating equipment.

    "The cooling capacity is 140kw? The power of this central air conditioner seems small." 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 can be connected in parallel." Chen Xin's father didn't care much about this, and even said it as a joke to Chen Xin.  One sentence: "Do you think central air conditioners are like circulating water cooling towers in factories, with a flow rate of several thousand tons? Small equipment cannot dissipate that much heat."

    Chen Xin thought about it for a while, and it seemed that this was indeed the case. After all, the related equipment he had come into contact with in his previous work were all large-scale equipment in factories. The kind of air-cooled cooling tower that uses circulating water as the cooling medium has a cooling capacity of only a few hours.  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.

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

    The warmth in the shelterThe temperature was indeed much higher than before, but the temperature only increased from 0¡ãC to a few degrees Celsius, which was really not a satisfactory level. Chen Xin felt that the output power could be increased a little more.

    Regarding this question, Chen Xin's father hesitated for a moment, then thought about it and asked Chen Xin: "How do you want to change it? How much investment will you make? How much will the output power increase after the change? How much will the power consumption increase?"

    As a manager who had been in charge of the equipment of a large state-owned chemical plant, Chen Xin's father had already formed a habit. When Chen Xin mentioned the transformation, he directly asked several key questions, and even almost wanted Chen Xin to come out.  A feasibility report is available.

    Regarding his father's professional habits for many years, Chen Xin did not find anything strange. He just thought about it and replied: "Improve the operating efficiency of the equipment, increase the output power, and increase the cooling capacity to 200kw. The increase in power consumption needs to be calculated."  , should not exceed 30%.¡±

    This is of course not data that Chen Xin made up casually, but a conclusion he came to by using the system's upgrade interface to observe the central air-conditioning outdoor unit in front of him.

    When Chen Xin's father heard what he said, he did not immediately agree, but continued to ask him: "Improving the output power is one way, but what is the efficiency of converting the output power into cooling capacity? And the original work  Has efficiency increased or decreased?

    You have just connected a 150kw battery. After modification, you have to consider whether it can still meet the working needs of the equipment and whether the entire circuit can withstand such a large load. You cannot just think about improving the efficiency of the equipment.  "

    Chen Xin¡¯s father has too much experience in this kind of equipment modification. He clearly knows that the modification of a piece of equipment is not simply about increasing the output power of the equipment.

    In his many years of work experience, he has encountered too many renovation cases where the data looked very good on the surface, but the actual transformation failed to achieve the expected results. Therefore, Chen Xin¡¯s idea of ????renovating the heating equipment of the shelter  He couldn't help but want to ask a few more questions.

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

    So after listening to his father¡¯s questions, Chen Xin reorganized his thoughts and made the system upgrade interface display a new upgrade plan, and then explained to his father in detail how he planned to transform it.

    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 accidents."  question."

    "I know, this is not urgent, and the transformation also requires materials. I have to ask my second uncle's opinion before he agrees to start the transformation." Chen Xin had no idea of ??accepting everything immediately.

    Seeing that Chen Xin had already thought about it, his father didn¡¯t say anything more and just nodded to him: ¡°Just think about it.¡±

    ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª

    Of course, there are more than three aspects that can be modified in the village's shelter: circuits, heating, and greenhouses. However, after Chen Xin carefully considered it and asked his father and his second uncle for their opinions, Chen Xin decided to only modify the shelter.  Transform these three aspects.

    Other parts of the shelter can also be renovated and upgraded, but compared to these three aspects, the remodeling and upgrading of other aspects is not as urgent, and the improvement of the quality of life is not that obvious.

    Although for Chen Xin, as long as the quality of life is improved, he can gain survival points, but in the eyes of the second uncle and others, there is no need to carry out renovation and upgrade in places that are not necessary.

    The second uncle is in favor of the renovation of circuits, heating and greenhouses, but for other renovations, because the improvement in the quality of life is not that obvious, in the eyes of the second uncle, this is a bit wasteful and extravagant.  Behavior.

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

    Chen Xin can also understand this, so he has no objection to the second uncle's plan to only transform three aspects.

    And Chen Xin¡¯s original intention is mainly to improve the quality of life of his relatives at home, because helping his relatives improve their quality of life and gaining survival points is just an expected extra gain for Chen Xin.

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

    After deciding to only modify the three aspects of circuit, heating and greenhouse, Chen Xin also made a list of materials needed for the modification and gave it to his second uncle. The second uncle also promised to go to the town as soon as possible to collect the materials.  together.  (Remember the website address: www.hlnovel.com)It turns out that since they decided to only improve the circuit, heating and greenhouse, Chen Xin would naturally not be too troublesome.
