Doomsday Bunker Upgrade

Seeing that the two brothers Han Ping and Han Ze were on top, there was no big problem. After Chen Xin chatted with them a few more times, he returned to the lower level of the shelter.

Compared with the low temperature of minus 20 degrees in the upper observation room even if the furnace is turned on, the temperature in the lower level of the shelter is still maintained at about 11 degrees after Chen Xin has operated the ground source heat pump at full power.

Although a human body will feel cold, it is not too cold.

However, this temperature is fine for the human body, but it is still a bit low for the crops grown in the greenhouse, especially when Chen Xin is still raising seedlings.

"Axin, the temperature in the greenhouse is still a bit low. I'm worried that there may be problems with raising seedlings. Do you want to use a seedling box?" Seeing Chen Xin's return, Mo Qingyan immediately found him and asked him .

Hearing Mo Qingyan's question, Chen Xin thought about it and said to her: "Try to cover the seeds with a damp cloth, and ensure that the temperature is above 20°C, there should be no big problem. If the temperature is still not enough, you can use seedlings. box."

"Okay, I'll try it first." Mo Qingyan nodded.

The effects of low temperature are many, and affecting the germination of seeds in the greenhouse is only one of them.

"Longniang, have all the vegetables that were ripe in the greenhouse harvested before?" Chen Xin asked Mo Qingyan, thinking of the vegetables that had not been harvested when Li Tou and the others came.

"You don't have to worry about that. I have already collected all the vegetables that can be harvested before the temperature cools down and sent them to the warehouse above." After speaking, Mo Qingyan seemed to be afraid that Chen Xin would worry about the stored vegetables. , continued to add: "As for the warehouse above, it is now the same as the frozen warehouse, and there is no need to worry about the vegetables being damaged when placed on it."

"Also be careful not to freeze." Chen Xin thought of the low temperature of minus 20 degrees above, and was not worried about what Mo Qingyan said.

At such a low temperature, all the vegetables will be frozen quickly after being put in, just like the quick freezing mode of the refrigerator, and there is no need to worry about it being damaged.

"However, there are still a lot of vegetables in that batch. There is no problem in temporarily storing them in the warehouse, but it's better to have the SWAT team send someone to take them away as soon as possible." Mo Qingyan was obviously worried that if the batch of vegetables could not be pulled in a short time Go, and she is sowing new seeds, and when the new vegetables are mature next month, it will be bursting.

Although this kind of question may sound unfounded, it is really a question of whether the snowstorm can stop within a month under such circumstances.

Chen Xin obviously also considered this problem, but he said not optimistically: "I'm afraid I won't be able to pull it in a short time. In this kind of blizzard weather, wanting to drive out is completely courting death."

"Is the situation serious outside?" When Chen Xin and Mo Qingyan were talking about this, Qin Lan also came over.

She was checking the chicks just now. Although the temperature of ten degrees is not too low for chickens, the chicks are still at risk of dying in the face of such low temperature, so Qin Lan will go to check the room where the chicken coop is located. , to avoid the temperature is too low to freeze the chicks to death.

Chen Xin nodded with a heavy expression: "Without the barrier of the forest, the wind speed on the surface has exceeded level 12, and the temperature has dropped below -70°C. If you don't have protective equipment, you won't be frozen if you go out for half an hour. Death, and most likely the front foot went out, and the back foot was blown away by the wind."

-

The low temperature of 70°C and the high winds above level 12 are completely incomprehensible to ordinary people. Such a harsh climate can only appear in the Antarctic continent, and even only in some places in the Antarctic continent will it be lower than -70. ℃ low temperature appears.

For modern humans, such low temperatures were unimaginable in life before the disaster.

"Minus seventy degrees? Oh my god!" Qin Lan couldn't help but exclaimed. She couldn't help but ask Chen Xin, "Can the shelter in the city withstand such a low temperature?"

In response to this question, Chen Xin shook his head, his complexion a bit heavy: "I'm afraid it's not enough, their insulation measures may not be able to resist this severe cold, and the efficiency of the heating equipment of coal-fired boilers is also limited, if the fuel supply can be guaranteed, it will be fine. Hold on. But…”

Chen Xin didn't finish his words, but Qin Lan and Mo Qingyan understood what he meant.

In such extremely bad weather, it may be difficult for even trains to continue to transport, and the city is likely to face the dilemma of lack of coal again.

Qin Lan and Mo Qingyan experienced the shortage of coal in the city last time. They knew exactly what the terrible consequences would be if the city's coal supply was interrupted.

This made Qin Lan nervous, reached out and grabbed Chen Xin's arm, and asked him, "Is there any way to solve this problem?"

Chen Xin shook his head bitterly. Although there is a system, he can use some black technology equipment to make his shelter cope with the cold winter without problems, but it is really embarrassing for him to solve the problems of the whole city. he is.

Seeing Chen Xin, there is no way, Qin Lan also understands that he is a strong man, so he can only let go of Chen Xin's arm with a look of disappointment.

Seeing Qin Lan's lost appearance, Chen Xin couldn't help comforting her: "Perhaps the situation is not as bad as you think, after what happened last time, the city government must have made an emergency plan, and there is emergency coal in reserve. They can handle this crisis."

Of course Qin Lan could hear that Chen Xin's words were just comforting, but at this time, he could only choose to think about the good side.

"I'm going to see how my dad is doing. I asked him to help check the ground source heat pump." Chen Xin said to Qin Lan and Mo Qingyan, and then walked to the room where the ground source heat pump was installed. .

In the room, Chen Xin's father was checking the operation of the ground source heat pump equipment and recording it in a notebook.

"Dad, how is the situation?" Chen Xin asked his father.

"At present, all equipment is running at full capacity, and the state is good for the time being. There is no problem." Chen Xin's father put away his pen and answered Chen Xin's question.

For Chen Xin's father, who has been working with machinery and equipment all his life in the factory, these ground source heat pumps are just a piece of cake for him, but these ground source heat pumps are involved in the heating of the entire shelter. , he is very serious about this matter.

So after answering Chen Xin's question, he also continued to Chen Xin: "Now all equipment is running at full capacity, and there is no backup equipment. In case of a failure and the equipment stops running, do you have any remedies?"

"Don't worry, Dad, I have prepared for this." Chen Xin really wasn't worried about damage to the equipment, he was only worried that the temperature would continue to drop, and these devices could not meet the heating needs.
