Doomsday Bunker Upgrade

When Chen Xin and Qin Lan were eating together, Uncle Ding and the political commissar also appeared in the cafeteria.

The two noticed Chen Xin and Qin Lan and walked over together.

"Xiao Qin, Comrade Xiao Chen, are you eating?" The political commissar greeted the two of them with a friendly smile: "Can I sit here?"

"There's no one here, the political commissar can sit down as you like." Qin Lan hurriedly greeted the political commissar to sit down, and Chen Xin, who was beside him, nodded and said hello.

The political commissar sat down to accompany Chen Xin and Qin Lan. Of course, it was Chen Xin who said this, while Uncle Ding went to the cafeteria window to get two meals, and then turned back and sat down as well.

"Did Comrade Xiao Chen start the equipment installation in the afternoon?" Although the political commissar behaved very politely, he did not have too many unnecessary greetings, and quickly led the topic to the main topic: "I don't know what needs our cooperation? We need us. Do your best to cooperate.”

"In terms of cooperation, it is mainly where you plan to install the equipment? How do you plan to install it." Chen Xin heard the political commissar's question, but he was not polite: "The installation of ground source heat pumps is different from other equipment, and the heat exchange pipes need to be buried deep. It goes into the ground, so drilling operations must be carried out, and a suitable installation site is also required.

As for the piping arrangement and heating arrangement, this is what you have planned. I am only responsible for the installation, operation and commissioning of the equipment. "

The political commissar nodded in understanding. Although Chen Xin was in charge of the on-site installation, the two parties had neither communicated the actual situation on the site nor the usage requirements. They just sent out a few recycled waste air conditioners, and Chen Xin pulled over six for renovation. For the ground source heat pump that followed, to say that Chen Xin could know how to install it would be a complete joke.

However, the political commissar is not unprepared for this issue.

What makes official shelters better than dead ones is that they have a large number of people, and no matter what they do, they can find enough people and professionals.

In addition, the city has done project planning for the utilization of shallow geothermal energy before, and it has been under construction. If it is not a disaster, it may be able to use shallow geothermal energy for heating in a year and a half, so find a professional There is no problem in planning the installation of heating pipes and equipment.

"In this regard, we have already asked a professional designer to do project planning, and the design drawings have also been produced. The main difference is Comrade Xiao Chen, the equipment specifications and pipe diameters on your side." The political commissar is very happy to Chen Xin introduced the situation, and said that the drawings were in the conference room of the SWAT team, and Chen Xin could look at it after dinner.

Chen Xin nodded clearly, and replied affirmatively: "Since there are drawings, it will be easier to talk about. Let's look at the drawings after dinner."

Hearing Chen Xin say this, the political commissar will naturally not object.

The four were eating, and Chen Xin asked Uncle Ding as if he had remembered something: "Uncle Ding, where is Xiao Ding? Didn't she come to eat?"

"A-Ning has a mission today, and now he's on duty outside and will come back at night." Uncle Ding didn't find it strange that Chen Xin asked Ding Ning, but just explained: "Now the city bureau's manpower is tight, even my daughter is nothing special. , must go out on duty."

Chen Xin is not qualified to comment on whether Ding Ning needs to go out on field duty. Although in his opinion, it is not a problem for Uncle Ding to get some preferential treatment for his daughter, but this is family affairs and the internal affairs of the SWAT team. No beak.

After eating, Chen Xin followed the political commissar and Uncle Ding to the conference room to check the drawings, while Qin Lan returned to his room.

Although they have a good relationship, the political commissar also said that Qin Lan should entertain Chen Xin, but it is obviously impossible for a female SWAT to do the reception all the time. Qin Lan also has her own tasks.

Especially in the past two days, she asked for leave to live at Chen Xin's place. Although she had legitimate reasons, she still delayed a lot of work.

Chen Xin didn't think there was anything wrong with this. After following the political commissar and Uncle Ding to the conference room, the political commissar quickly fetched drawings for him.

"Are you planning to install the ground source heat pump equipment on this layer, and then connect the heat exchange tubes installed on the lower layer through pipes?" Chen Xin spread out the drawings and looked at the piping layout design above, but did not propose any revisions I just nodded: "There is no problem with piping like this, but the equipment I brought didn't have so many pipes, you need to pipe it yourself, and the radiator itself, which is not included in the ground. In the source heat pump equipment, I am not responsible for the installation."

"Of course, we have all prepared for these things. As long as we confirm the diameter of the ground source heat pump equipment you made, Comrade Xiao Chen, we can complete the pipeline." The political commissar affirmed.

Chen Xin didn't say much about this, but said to them: "In this case, I need to see the actual situation of the installation site, and the installation of heat exchange tubes requires drilling. I asked Alan to tell you before that I need a drill bit. , I don't know if you are ready?"

"You can rest assured, Comrade Xiao Chen. We have already prepared the drill bit. It is a drill bit for drilling wells. It can drill dozens of meters deep." ring.

Chen Xinjian had already understood the situation, so he didn't say anything, just said that he was going to see the on-site situation of the installation site.

Of course, the political commissar would not object, and personally took Chen Xin to the installation site that was planned to be used as a computer room in the future, and also called an engineer.

This is a specially reserved room, and the six ground source heat pump equipment sent by Chen Xindong is also temporarily placed here.

Chen Xin checked the situation in the room and took out a tape measure to measure the data.

While busy, Chen Xin also expressed curiosity about the two huge cylindrical water tanks placed in this room: "What are these two water tanks for?"

"This is a thermal energy storage tank. Private shelters may not use this thing, but if we are here, we need to use this to collect and store thermal energy, and then use it for heating." The engineer explained on the side, he seemed to have an interest in Chen Xin. An inexplicable worship.

In the environment of the apocalypse, people who can use only the waste air conditioner to rub out a ground source heat pump by hand are indeed very powerful for those who understand the difficulty of machining and manufacturing, and it is not surprising that they have a feeling of worship.

But after listening to the engineer's words, Chen Xin nodded and said: "This is not necessarily true. If there is such an energy storage tank, for private shelters, in addition to being used for heating, it also means that there can be Hot water is available for 24 hours. Even if the equipment is shut down, the hot water stored here will be enough for a while.”

Seeing what Chen Xin said, the engineer showed great interest and chatted with Chen Xin a lot about the technical issues of ground source heat pump equipment.
