    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, political commissar, you can sit down wherever you like." Qin Lan hurriedly asked the political commissar to sit down, and Chen Xin on the side also nodded in greeting.

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

    "Comrade Xiao Chen, will you start the equipment installation in the afternoon?" Although the political commissar was very polite, he did not have too many unnecessary greetings and quickly brought the topic to the topic: "I wonder if there is anything we need to cooperate with? We need our cooperation.  We must do our best to cooperate.¡±

    "In terms of cooperation, the main thing is where do you plan to install the equipment? And how do you plan to install it." When Chen Xin heard the political commissar ask this, he was not polite: "The installation of ground source heat pumps is different from other equipment. The heat exchange pipes need to be buried deeply.  into the ground, so drilling operations must be performed, and a suitable installation location is also required.

    As for the pipeline layout and heating arrangements, this is what you plan for yourself. I am only responsible for the installation, operation and debugging of the equipment.  "

    The political commissar nodded understandingly. Although Chen Xin was responsible for the door-to-door installation, the two parties neither communicated about the actual situation on site nor the usage requirements. They only sent a few recycled waste air-conditioning outdoor units, and Chen Xin brought over six units for renovation.  For subsequent ground source heat pumps, if Chen Xin knew how to install them, that would be a lie.

    ¡°However, the political commissar was not unprepared for this issue.

    The advantage of official shelters over the shelters of the dead is that they have a large number of people, and they can find enough manpower and professionals no matter what they want to do.

    In addition, this city has made project plans for the utilization 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 and a half, so find a professional.  It will be no problem for professionals to plan the installation of heating pipes and equipment.

    "In this regard, we have already hired professional designers to do project planning, and the design drawings have been produced. The main thing that is missing is Comrade Xiao Chen's equipment specifications and pipe diameters." The political commissar told Chen very happily  Xin introduced the situation and said that the drawings were in the conference room of the SWAT team, and Chen Xin could go and see them after eating.

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

    Hearing what Chen Xin said, the political commissar naturally would not object.

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

    "A Ning has a mission today. He is on duty outside now and will come back in the evening." Uncle Ding did not find it strange that Chen Xin asked Ding Ning. He just explained: "The city bureau is currently short of manpower. Even my daughter is nothing special."  , must go on duty outside."

    Chen Xin is not qualified to comment on whether Ding Ning needs to go out on field duty. Although in his opinion, there is no problem for Uncle Ding to get some preferential treatment for his daughter, this is a family matter and an internal matter of the SWAT 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 returned to her room.

    Although they have a good relationship and the political commissar also asked Qin Lan to entertain Chen Xin, it is obviously impossible for a female special police officer to do the reception work all the time. Qin Lan still has her own tasks.

    Especially since she took leave to stay at Chen Xin's place for the past two days. 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.

    "Are you planning to install the ground source heat pump equipment on this floor, and then connect the heat exchange pipes installed on the lower floor through pipes?" Chen Xin spread out the drawings, looked at the pipeline layout design above, and did not propose modifications.  He just nodded: "There is no problem in laying out the pipes like this, but the equipment I brought did not prepare so many pipes. You need to arrange the pipes yourself, as well as the radiator itself. These are not included in the floor.  I am not responsible for the installation of source heat pump equipment.¡±

    "Of course, we have prepared these things. As long as we confirm the diameter of the ground source heat pump equipment you made, Comrade Xiao Chen, we can match the pipelines." The political commissar assured.

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

    "Comrade Xiao Chen, don't worry. We have already prepared the drill bits. They are used to drill wells. It can drill to a depth of dozens of meters." The political commissar assured him of this and beat his chest hard.  ring.

    Seeing that Chen Xin already understood the situation, he didn¡¯t say anything more. He just said that he wanted to see the on-site conditions at the installation site.

    Of course, the political commissar would not object. He 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 room specially set aside, and the six ground source heat pump equipment sent by Chen Xin are also temporarily placed here.

    Chen Xin checked the condition of the room and took out a tape measure to measure the data seriously.

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

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

    ¡° In this post-apocalyptic environment, someone who can build a ground source heat pump using only a used outdoor air conditioner unit is indeed very impressive to those who understand the difficulty of mechanical processing and manufacturing, and it is not surprising that he will be worshiped.

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

    Seeing what Chen Xin said, the engineer was very interested and chatted with Chen Xin a lot about the technical issues of ground source heat pump equipment.  (Remember the website address: www.hlnovel.com
