Seeing that the two brothers Han Ping and Han Ze didn't have any major problems above, Chen Xin chatted with them for a few more words before returning to the lower level of the shelter.
"Compared with the low temperature in the upper observation room, which is only minus 20 degrees even if the stove is turned on, the temperature in the lower level of the shelter is still maintained at about 11 degrees after Chen Xin has turned the ground source heat pump on at full power.
It means that although a human body feels cold, it is not too cold.
¡°However, this temperature is fine for the human body, but it is still a bit low for growing crops in the greenhouse, especially when Chen Xin is still raising seedlings.
"A Xin, the temperature in the greenhouse is still a bit low at present. I'm worried that there may be problems with the seedlings. Do you want to use a seedling box?" Seeing Chen Xin come back, Mo Qingyan immediately approached him and asked him .
Hearing Mo Qingyan's question, Chen Xin thought for a while and said to her: "Try covering the seeds with a damp cloth and make sure the temperature is above 20 degrees Celsius. There shouldn't be any big problem. If the temperature is still not enough, you can use a seedling box." .¡±
"Okay, I'll give it a try first." Mo Qingyan nodded.
Low temperature has many effects, and affecting the germination of seeds in a greenhouse is just one of them.
"Dragon Niang, have all the previously mature vegetables in the greenhouse been harvested?" Chen Xin asked Mo Qingyan, thinking of the vegetables that had not been harvested when Li Tou and the others came.
"Don't worry about that. I have already harvested all the vegetables that can be harvested before the temperature drops and sent them to the warehouse above." After saying that, Mo Qingyan seemed to be afraid that Chen Xin would not worry about the stored vegetables. , and continued to add: "As for the warehouse above, it is now the same as a cold storage. You don't have to worry about the vegetables getting spoiled when you put them there."
"Be careful not to freeze." Chen Xin thought of the low temperature above -20 degrees below zero, and was not worried about the problem Mo Qingyan said.
At such a low temperature, all vegetables will be frozen quickly after being put in, just like the refrigerator is in quick-freezing mode, so there is no need to worry about them being damaged if left unattended.
"But there are still a lot of vegetables in that batch. It's okay to store them in the warehouse for the time being. But it's best to have the SWAT team send people to take them away as soon as possible." Mo Qingyan was obviously a little worried. If the batch of vegetables can't be taken out in a short time, Go, and she is sowing new seeds. When the new vegetables mature next month, the stock will explode.
Although this question sounds a bit unfounded, under the current circumstances, whether the snowstorm can stop within a month is really a question.
Chen Xin has obviously considered this issue, but he said unoptimistically: "I'm afraid we won't be able to pull it in a short time. In this kind of blizzard weather, if you want to drive out, you are totally courting death."
"Is the situation outside serious?" While Chen Xin and Mo Qingyan were talking, Qin Lan also walked over.
She was checking the chicks just now. Although the temperature of more than ten degrees is not too low for chickens, the chicks are still at risk of dying when faced with this low temperature. That's why Qin Lan went to check the room where the chicken coop is located. , to prevent the chicks from freezing to death due to low temperatures.
Chen Xin nodded with a heavy face: "Without the protection of the forest, the wind speed on the surface has exceeded level 12, and the temperature has dropped below -70c. If you don't have protective equipment, you will freeze to death in half an hour if you go out. , and it is very likely that when the front foot stepped out, the back foot was blown away by the wind."
The low temperature of -70C and the strong winds above level 12 are completely unknown to ordinary people. Such harsh climate originally only appeared in the Antarctic continent, and even only in some parts of the Antarctic continent could the temperature be lower than -70C. low temperatures appear.
For modern humans, such low temperatures are unimaginable in life before the disaster.
"Seventy degrees below zero? Oh my god!" Qin Lan couldn't help but exclaimed. She couldn't help but ask Chen Xin: "Can the urban shelters withstand such a low temperature?"
Regarding this question, Chen Xin shook his head and looked a little heavy: "I'm afraid it's too bad. Their insulation measures may not be able to withstand the severe cold, and the efficiency of the coal-fired boiler's heating equipment is also limited. If the fuel supply can be guaranteed, it will be okay. Hold on. But"
Chen Xin didn't finish what he said, but both Qin Lan and Mo Qingyan understood what he meant.
¡°In such extremely bad weather, it may be difficult for even trains to continue transportation, and the city is likely to once again face the dilemma of lack of coal.
Qin Lan and Mo Qingyan both experienced the coal shortage in the city last time, and they clearly know the dire consequences if the city's coal supply is interrupted.
??This made Qin Lan nervous. She 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 was a system and he could come up with some high-tech equipment to make his shelter cope with the cold winter without causing problems, it was really difficult for him to solve the problems of the entire city. He did.
Seeing that Chen Xin had no choice, Qin Lan also understood that she was forcing someone to make things difficult for her, so she could only let go of Chen Xin's arm with a look of disappointment.
Seeing Qin Lan's disappointed look, Chen Xin couldn't help but comfort her: "Maybe the situation is not as bad as you thought. After what happened last time, the city government must have made an emergency plan and had emergency coal reserves. They can handle this crisis."
Of course Qin Lan could tell that Chen Xin's words were just comfort, but at this time she could only choose to think on the bright side.
"I'm going to see how the situation is at my dad's place. I asked him to help check the situation of the ground source heat pump." Chen Xin said to Qin Lan and Mo Qingyan before walking 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.
"Currently, all equipment is running at full capacity and is in good condition for the time being. There are no problems." Chen Xin's father put away his pen and answered Chen Xin's question.
For Chen Xin's father, who has worked with machinery and equipment in factories all his life, these ground source heat pumps are just a piece of cake for him, but these ground source heat pumps involve heating of the entire shelter. , he is still very serious about this matter.
So after answering Chen Xin's question, he continued to Chen Xin: "Now all the equipment is running at full capacity and there is no backup equipment. In case of failure and the equipment stops running, do you have any remedial measures?"
"Don't worry, dad, I'm prepared for this." Chen Xin is really not worried about equipment damage. He is only worried that the temperature will continue to drop and these pieces of equipment will not be able to meet the heating needs. (Remember the website address: www.hlnovel.com
