Doomsday Bunker Upgrade Chapter 139: Site investigation
"I can upgrade the shelter ()" to find the latest chapter!
While 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 with a friendly smile: "Can I sit here?"
"There is no one here, the political commissar, sit down here." Qin Lan hurriedly greeted the political commissar and sat down, and Chen Xin 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, then turned back and sat down as well.
"Did Comrade Xiao Chen start the equipment installation in the afternoon?" Although the political commissar was very polite, he did not have too many unnecessary greetings, and quickly turned the topic to the main topic: "I don't know if there is anything that needs our cooperation. We need to do our best to cooperate.”
"In terms of cooperation, the main issue is where do you plan to install the equipment? How do you plan to install it." Chen Xin was not polite when he heard the political commissar's question: "The installation of a ground source heat pump is different from other equipment. The pipe is deeply buried in 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 plan for yourself. I am only responsible for the installation, operation and debugging 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 a few recycled waste air conditioners and Chen Xin pulled them over. For the six ground-source heat pumps after the renovation, if Chen Xin knows how to install them, that's nothing but a ghost.
However, the commissar is not unprepared for this issue.
The advantage of official refuges over dead people’s refuges is that they have a large number of people. No matter what they do, they can find enough manpower 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 Hiring a professional to plan your heating plumbing and equipment installation is no problem.
"In this regard, we have found a professional designer to do project planning, and the design drawings have been prepared. The main difference is Comrade Xiao Chen's equipment specifications and pipe diameters on your side." The political commissar was very happy. He introduced the situation to Chen Xin, and said that the drawing was in the meeting room of the SWAT team, and Chen Xin could go and see it after eating.
Chen Xin nodded clearly, and replied affirmatively: "Since there are drawings, it's much easier to talk about. Then, after eating, go and look at the drawings."
Hearing Chen Xin say this, the political commissar will naturally not object.
The four of them were eating, and Chen Xin asked Uncle Ding as if thinking of something: "Uncle Ding, where is Xiao Ding? Didn't she come to eat?"
"A Ning has a mission today, and is now 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 is tight, even my daughter can't handle it. Nothing special, you have to go outside 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 okay for Uncle Ding to get some preferential treatment for his daughter, but this is a family affair and the internal affairs of the SWAT team. Chen Xin also has no way to cause a beak.
After eating, Chen Xin followed the political commissar and Uncle Ding to the conference room to check the drawings, while Qin Lan went back to her room.
Although they have a good relationship, the political commissar also said that Qin Lan will entertain Chen Xin, but it is obvious that a female special police officer cannot always do reception work. Qin Lan still has her own mission.
Especially in the past two days, she took time off to live with Chen Xin. Although she had a valid reason, she still missed 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 the drawings for him.
"Do you plan to install the ground source heat pump equipment on this floor, and then connect the heat exchange tubes installed on the lower floor through pipes?" Chen Xin spread out the drawings, looked at the piping layout design above, and said He didn't propose any amendments, just nodded: "There is no problem with piping like this, but the equipment I brought didn't have so many pipes, so you need to do the piping yourself, and the radiator itself, this is not a problem. I am not responsible for the installation of those included in the ground source heat pump equipment."
"Of course, we have all these things prepared. As long as you have confirmed the pipe diameter of the ground source heat pump equipment made by Comrade Xiao Chen, you will be able to complete the pipes." The political commissar affirmed.
Chen Xin didn’t say much about this, but just said to them: “In this case, I need to look at the actual situation of the installation site. In addition, installing the heat exchange tube requires drilling. I asked Alan to tell you before. I need a drill, are you ready?"
"You can rest assured, Comrade Xiao Chen~IndoMTL.com~ We have already prepared the drill bit. It is a drill bit for drilling wells. It can drill dozens of meters deep." , slapped the chest with a thud.
Chen Xinjian has already understood the situation, so he didn't say anything, but said that he wanted to see the scene of the installation site.
Of course, the political commissar would not object, and personally took Chen Xin to the installation site that he planned to use as the computer room in the future, and at the same time called an engineer.
This is a room specially set aside, and the six ground-source heat pump equipment sent by Chen Xindao have also been temporarily placed here.
Chen Xin checked the condition of the room, and took out a tape measure to measure the data in a meaningful way.
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, which may not be used in private shelters, but we need to use this to collect and store thermal energy here, and then use it for heating." The engineer explained on the side. Xin seems to have an inexplicable worship.
In the environment of the apocalypse, people who can use only waste air conditioners 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 feelings of worship. Up.
But after listening to the engineer’s words, Chen Xin nodded and said, “This is not always true. With such an energy storage tank, for private shelters, in addition to heating, it also means There will be hot water 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.
