Chapter 281

Seeing that Han Ping and Han Ze didn't have any big problems, Chen Xin chatted with them again, and then returned to the lower level of the refuge.

Compared with the observation room on the upper floor, where even if the furnace is turned on, the temperature is only 20 degrees below zero. After Chen Xin has run the ground source heat pump at full power, the temperature on the lower floor of the shelter is still about 10 degrees.

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

However, the temperature is OK for the human body, but it is still a little low for the crops in the greenhouse, especially for Chen Xin who is still breeding.

"Ah Xin, the temperature in the greenhouse is still a little low. I'm worried that there may be problems in seedling raising. Do you want to use a seedling box?" Seeing Chen Xin coming back, Mo Qingyan finds him for the first time and asks him.

Hearing Mo Qingyan's inquiry, Chen Xin thought for a moment and said to her, "try to cover the seeds with a wet cloth. It shouldn't be a big problem to ensure that the temperature is above 20 ℃. If the temperature is still not enough, you can use a seedling box."

"OK, I'll try first." Mo Qingyan nodded.

There are many effects of low temperature, and the effect on Seed Germination in greenhouse is only one of them.

"Long Niang, have you harvested all the mature vegetables in the greenhouse before?" Chen Xin thought of the vegetables that had not been harvested when they came to Li Tou and asked Mo Qingyan.

"You don't have to worry about that. I've picked all the vegetables that can be harvested before cooling down and sent them to the warehouse above." With that, Mo Qingyan seems to be afraid that Chen Xin is not sure about the stored vegetables. She continues to add: "as for the warehouse above, it's the same as the frozen warehouse now. There's no need to worry about the damage of vegetables on it."

"And be careful not to freeze out." Chen Xin thought of the low temperature above, which was more than 20 degrees below zero, and didn't worry about what Mo Qingyan said.

At such a low temperature, all vegetables will be frozen quickly after they are put in, just like the quick freezing mode in the refrigerator, so there is no need to worry about the damage.

"But there are still a lot of vegetables. It's no problem to put them in the warehouse for the time being, but it's better to ask the special police to send someone to pull them away as soon as possible." Mo Qingyan is obviously worried. If that batch of vegetables can't be taken away in a short time, and she is planting new seeds and waiting for the new vegetables to mature next month, it will explode.

Although this kind of problem sounds a little worrisome, under the current situation, whether the Blizzard can stop within a month is really a problem.

Chen Xin obviously also considered this problem, but he was not optimistic: "I'm afraid we can't get here in a short time. In this snowstorm weather, it's all death to drive out."

"Is it serious outside?" When Chen Xin and Mo Qingyan say these things, Qin Lan also comes over.

She was checking the chickens just now. Although the temperature of more than ten degrees is not low for chickens, the chicks still have the risk of premature death in the face of this low temperature. That's why Qin LAN went to check the room where the chicken coop is, so as to avoid freezing the chicks to death.

Chen Xin nodded with a heavy face: "without the forest, the wind speed on the surface has exceeded level 12, and the temperature has dropped below - 70 ℃. If there is no protective equipment, it will freeze to death within half an hour after going out, and it is very likely that the front foot will go out, and the back foot will be blown away by the wind."

-A low temperature of 70 ℃ and a gale of force 12 or above are totally inconceivable to ordinary people. Such a bad climate would only appear in the Antarctic continent, and even a low temperature below - 70 ℃ would only appear in some places of the Antarctic continent.

For modern humans, such a low temperature is unimaginable in life before the disaster.

"Seventy below zero? Oh, my God Qin LAN can't help exclaiming. She can't help asking Chen Xin, "can the shelter in the city bear such a low temperature?"

For this problem, Chen Xin shook his head and looked a little heavy: "I'm afraid it's choking. Their thermal insulation measures may not be able to withstand the severe cold, and the efficiency of the heating equipment of coal-fired boilers is also limited. If they can guarantee the fuel supply, they can still stick to it. But... "

Chen Xin's words did not finish, but Qin LAN and Mo Qingyan understood his meaning.

In such extreme weather, I am afraid that even the train is difficult to continue to transport, and the city is likely to face the shortage of coal again.

The last time there was a shortage of coal in the urban area, Qin LAN and Mo Qingyan experienced it personally. They knew clearly what terrible consequences would be if the coal supply in the city was interrupted.

This makes Qin LAN nervous. She reaches for Chen Xin's arm and asks him, "is there any way to solve this problem?"

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

See Chen Xin also have no way, Qin Lan also understand that he is forced, only a face of loss released Chen Xin's arm.

Seeing Qin Lan's loss, Chen Xin comforted her: "maybe the situation is not as bad as you think. After what happened last time, the city government must have made an emergency plan and reserved emergency coal. They can deal with this kind of crisis."Of course, Qin LAN can hear that Chen Xin's words are just consolation, but at this time, she can only choose to think about the good side.

"I'm going to see what's going on with my dad. Before that, I asked him to check the ground source heat pump." Chen Xin said to Qin LAN and Mo Qingyan, and then went to the room where the ground source heat pump was installed.

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

"Dad, how's it going?" Chen Xin asked his father.

"At present, all the equipment are running at full load, in good condition for the time being, no problem." Chen Xin's father put away his pen and answered Chen Xin's question.

For Chen Xin's father, who has worked with mechanical equipment all his life in the factory, these ground source heat pumps are just a piece of cake for him. However, these ground source heat pumps involve the heating of the whole refuge, and he is very serious about it.

So after answering Chen Xin's question, he continued to say to Chen Xin, "now all the equipment is running at full load, and there is no standby equipment. In case of a failure that causes the equipment to stop running, do you have any remedial measures?"

"Don't worry, Dad. I'm prepared for that." Chen Xin is really not worried about equipment damage. He is only worried that the temperature will continue to drop, and these equipment will not meet the heating needs.
