Chen Xin did not know how powerful the function of the system was, and the results he analyzed were just the product of the black hole contemplation above the neck of the online writer.

But this does not prevent Chen Xin from using this system and knowing how to use it to make the system achieve his intended ideas.

"But before we do that, let's get down to business!" Chen Xin took a deep breath, closed his laptop, and after cleaning up the remnants of breakfast, he came to the radio station.

Last night's sudden drop in temperature had a big impact on someone like him, who had a solid and reliable shelter, and it was hard to imagine what would become of those shelters in the city.

Especially a few friends in the urban area, Chen Xinke still owes people six oxygen concentrators! Before these 600 survival points were collected, Chen Xin didn't want them to hit the street like this.

"Call, this is the writer, it suddenly cooled down last night, everyone is okay, right?" turned on the radio station, and although it was not the fixed communication time agreed upon by everyone, Chen Xin still made a call.

"This is an old vegetable farmer, last night there was a sudden snowstorm in the city, the temperature dropped by 30 degrees, and now it is only -35 °C, I was directly frozen last night, half of the vegetables in the greenhouse were frosted, and the loss was heavy!" The first to respond to Chen Xin was Li Wensheng, his voice was full of distress, obviously last night's cooling made him lose a lot.

Through Li Wensheng's words, Chen Xin understood what happened last night, and at the same time had a clear understanding of the impact of the sudden snowstorm last night.

Chen Xin's blocking situation with mountains is not bad, but Li Wensheng's refuge is directly under his villa, and in terms of thermal insulation and thermal insulation, it is undoubtedly far worse.

From Li Wensheng's words, Chen Xin can know that the temperature in his shelter has at least fallen below zero, otherwise the vegetables in his greenhouse would not have frosted.

Thinking of this, Chen Xin couldn't help but feel a little worried about them.

Although private shelters are built underground like official shelters, and people with more money can do the same thermal insulation as official shelters built by the state, this will undoubtedly greatly increase the cost.

Like Chen Xin's shelter, he made a layer of polyurethane insulation into the walls, which also took up a large part of the cost of building the shelter in the first place.

But this is not something that everyone has enough funds to get, such as the "doctor's" house, Chen Xin knows that he did not make polyurethane insulation because of financial problems, but used styrofoam.

Li Wensheng is in a better situation than the "doctor", he uses ultra-fine glass wool, while Mo Qingyan's household uses the same polyurethane as Chen Xin.

Styrofoam and ultra-fine glass wool are both thermal insulation materials used in the cockpit and cockpit of aircraft, although the performance of foam is not bad, but the effect is worse than that of ultra-fine glass wool, let alone compared with polyurethane.

As for the shelters of other group members, although they are also equipped with thermal insulation materials, most of them are made of the same styrofoam as the "doctor's" house.

This relatively inexpensive material has average performance as an insulating material, but the price is very affordable, and it is indeed a good choice for people who do not have much money to build a private shelter.

It's just that in the face of this kind of snowstorm that drops by 30 degrees overnight, there is a question mark about how much effect Styrofoam can play.

Fortunately, with Li Wensheng's voice, everyone else also replied after hearing the call, after all, the snowstorm brought about a drop of 30 degrees overnight, and everyone was seriously affected, and it is possible to contact others in time at this time to get help.

Listening to everyone report their situation one by one, Chen Xin couldn't help but feel a little heavy.

In addition to him and Mo Qingyan, two of the shelters built by the ten group members in the urban area could not hold on, and chose to send a distress message to the official shelter.

Chen Xin knew that the two group members who gave up, their shelter was converted into a small garage, although it was still well-equipped, well-prepared, and stockpiled a lot of supplies, but it was obvious that their shelter still lacked sufficient resistance in the face of this level of severe cold.

If it weren't really untenable, who would leave a comfortable private shelter and squeeze into an official shelter?

The abandonment of the two group members made everyone's mood a little heavy, and Chen Xin wanted to do something for them.

It's just that even if Chen Xin has a system that can help them, these two group members who chose to give up are no longer able to withstand the cold at this time, so they can only light a bonfire in the shelter with the reserved fuel to keep warm, waiting for the official rescue, and they can't last too long.

Unless Chen Xin can build heating equipment or provide them with better thermal insulation measures in the shortest possible time, they can only freeze to death.

But the snowstorm outside did not stop, in this weather, even if Chen Xin wanted to save people, he did not have the ability to save people, and it was impossible for Chen Xin to drive out against the snowstorm in this weather.

However, Chen Xin still said in the communication channel: "Everyone, I can build a ground source heat pump device that uses ground temperature to heat the house, but the manufacture of this equipment requires compressors, evaporators, condensers and expansion valves.

To put it simply, you can think of it as an air conditioner, and the materials needed to make the equipment are all on the air conditioner. As long as you can bring me these parts, I can build a ground source heat pump unit for you. ”

"You're not kidding the ingredients, are you? Can you really build a ground source heat pump? Mo Qingyan questioned Chen Xin, she and Chen Xin were too familiar, and she had never heard of Chen Xin having such a talent.

And since Chen Xin has such a ability, why didn't he say that he could make a ground source heat pump before the disaster?

At that time, they had far more resources to use and more convenient than they do now, whether it was collecting materials or installing equipment.

"I can do it, but it takes a lot of material to make a machine like this." When Chen Xin heard Mo Qingyan's questioning, he naturally understood that his behavior seemed suspicious, but he still explained: "I have been reading books on mechanical manufacturing these days and have accumulated a little experience, it is no problem to manufacture a device like this, as long as you can provide materials." ”

There may be no problem with manufacturing equipment, but it is clear that the matter is not the end of the process.

Although Mo Qingyan believed that Chen Xin could indeed manufacture a ground source heat pump device as heating equipment, she still asked Chen Xin: "But Ah Xin, the ground source heat pump pipeline you said is to be buried underground, right?" Even if you don't have to hit a few hundred meters deep, you still need dozens of meters, right? Now the temperature is more than 30 degrees below zero, and the ground has long been frozen hard, what do we use to make holes in the ground? ”
