Chapter 139: Site survey

"I can upgrade the shelter ( to find the latest chapter!
While Chen Xin and Qin Lan were eating together, Ding Shu and the political commissar also appeared in the cafeteria.
The two noticed Chen Xin and Qin Lan, and they 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. 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 was very polite, there was not much extra greeting, and he quickly led the topic to the topic: "I don't know what we need to cooperate? We need us. We must do our 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 asking so, and he was not polite: "The installation of ground source heat pumps is different from other equipment, and the heat exchange tubes need to be buried deep. 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 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 responsible for the door-to-door installation, the two sides neither communicated the actual situation on site nor the demand for use. They just sent a few recycled external air conditioners, and Chen Xin brought six of them for renovation. For the ground-source heat pump afterwards, if Chen Xin knew how to install it, that was totally a coax.
However, the political commissar is not unprepared for this issue.
The reason that official refuges are better than refuges for the dead is that they have a large number of people. No matter what they do, they can find enough people and professionals.
In addition, the city has done project planning for the use of shallow geothermal energy before, and it has been under construction. If it is not a disaster, it may be possible to use shallow geothermal energy for heating in a year or a half, so find a professional There is no problem in planning the installation of heating pipes and equipment.
"In this regard, we have found a professional designer to do the 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 to Chen Chen Xin introduced the situation and said that the drawings were 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 easier to talk about it. Then, after dinner, go and look at the drawings."
Hearing what Chen Xin said, the political commissar would 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 task today. He is on duty outside and will come back at night." Uncle Ding was not surprised by Chen Xin's question to Ding Ning. He just explained: "Now the city bureau is very tight, and even my daughter is nothing special. , Must go outside on duty."
Chen Xin does not have the right to comment on whether Ding Ning needs to go out to perform field duties. Although in his opinion, it is not a problem for Ding Shu to win some preferential treatment for his daughter, but it is the family affair and the internal affairs of the special police team. Chen Xin also No way to 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 very good relationship, and 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 leave to live with Chen Xin. Although she had a valid reason, her work was still delayed a lot.
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 and looked at the piping layout design above, and did not propose to modify it I just nodded my head: "There is no problem with arranging the pipes like this. However, the equipment I brought does not have so many pipes. This requires you to piping and the radiator itself. This is not included in the ground. I am not responsible for installing the source heat pump equipment."
"Of course, we are all prepared for these things. As long as the pipe diameter of the ground source heat pump equipment manufactured by Comrade Xiao Chen is confirmed, the pipes can be completed." The political commissar assuredly made a guarantee.
Chen Xin didn't say much about this, but 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 that I need a drill. , Don’t know if you are prepared?"
"Comrade Xiao Chen, don't worry, we have already prepared the UU Reading www.uukānshu.com drill bit. It is a drill bit used to drill wells. It can be drilled tens of meters deep." , Banging my chest.
Chen Xin saw that he had already understood the situation, so he didn't say anything, only 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 also 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.
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 refuges may not use this thing, but we need to use this to collect and store the thermal energy, and then use it for heating." The engineer explained to the side that he seemed to have something about Chen Xin. An inexplicable worship.
In this apocalyptic environment, it is not surprising that people who can hand-wrap out a ground-source heat pump with only a waste air-conditioning machine are indeed very powerful for those who understand the difficulty of mechanical processing and manufacturing.
However, after hearing 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 Hot water is available for 24 hours. Even if the equipment is down, the hot water stored in it will be enough for a while."
Seeing what Chen Xin said, the engineer was very interested and talked a lot about the technical issues of ground source heat pump equipment with Chen Xin.
