Chapter 140

When Chen Xin and Qin LAN are having dinner together, Ding Shu and political commissar also appear in the canteen.

They noticed Chen Xin and Qin LAN and came over together.

"Xiao Qin, Comrade Chen, are you eating?" Commissar to two people very cordial smile said hello: "can I sit here?"

"There's no one here. Political commissar, please sit down." Qin LAN quickly greets the political commissar and sits down, while Chen Xin nods to say hello.

The commissar sat down with Chen Xin and Qin LAN. Of course, it was Chen Xin who said this, while Ding Shu went to the window of the canteen to get two meals. Then he turned back and sat down.

"Did Comrade Chen start the equipment installation in the afternoon?" Although the political commissar was very polite, he didn't have too many extra greetings and soon turned the topic to the main topic: "I don't know what we need to cooperate with? We need to do our best to cooperate. "

"In terms of cooperation, where are you going to install the equipment? And how are you going to do it? " When Chen Xin heard the political commissar's question, he was not polite: "the installation of ground source heat pump is different from other equipment. The heat exchange tube needs to be deeply buried in the ground, so it is necessary to carry out drilling operation, and at the same time, it also needs to have a suitable installation site.

As for the pipe layout and heating arrangement, that's what you plan for yourself. I'm only responsible for the installation, operation and commissioning of the equipment. "

The political commissar nodded his head. Although Chen Xin was responsible for the door-to-door installation, there was neither the actual situation of the site nor the demand for the use of the ditch. He just sent a few recycled waste air-conditioning external units to Chen Xin, who brought in six ground source heat pumps after the transformation. If Chen Xin could know how to install them, it would be a complete hoax.

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

What makes official shelters better than shelters for the dead is that they have so many people that they can find enough people and professionals no matter what they have to do.

In addition, the city has made project planning for the use of shallow geothermal energy before, and 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 it is no problem to find a professional to do the heating pipe and equipment installation planning.

"In this regard, we have found a professional designer to do the project planning, and the design drawings are also good. The main difference is Comrade Chen's equipment specifications and pipe diameters on your side." The political commissar was very happy to introduce the situation to Chen Xin, and said that the drawing was in the conference room of the special police team, and Chen Xin could go to see it after eating.

Chen Xin nodded clearly and replied positively: "since there are drawings, it's easier to say. After dinner, go to see the drawings first."

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

As they were eating, Chen Xin seemed to think of something and asked Uncle Ding, "Uncle Ding, where's Xiao Ding? Didn't she come to dinner? "

"Ah Ning has a mission today. Now he is on duty outside. He will come back in the evening." Uncle Ding didn't feel strange about Chen Xin's involvement in Ding Ning. He just explained: "now the city bureau is short of manpower. Even my daughter is nothing special. She has to go out on duty."

Chen Xin is not qualified to comment on whether Ding Ning needs to go out to take charge of the field. Although in his opinion, uncle Ding has no problem fighting for some preferential treatment for his daughter, Chen Xin can't say anything about whether it's family affairs and the internal affairs of the special police force.

After dinner, Chen Xin followed political commissar and uncle Ding to the conference room to check the drawings, while Qin LAN went back to his room.

Although they have a good relationship, and the political commissar also said that Qin LAN should treat Chen Xin well, it's obvious that a female special police officer can't always do reception work. Qin LAN still has her own task.

Especially in the past two days, she asked for leave to live with Chen Xin. Although she had a good reason, her work was 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 got the drawings for him.

"Do you plan 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 unfolded the drawing and looked at the above pipeline layout design. He didn't put forward any suggestions for modification, but nodded: "there's no problem with such pipe layout, but the equipment I brought with me doesn't have so many pipes to prepare, which requires your own piping. At the same time, there is the heater itself, which is not included in the ground source heat pump equipment, and I'm not responsible for the installation. ”

"of course, we have all these things ready. As long as we have confirmed the pipe diameter of the ground source heat pump equipment you made by Comrade Xiao Chen, we can complete the pipes." The commissar made sure.

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. In addition, the installation of heat exchange tubes needs drilling. I asked Alain to tell you that I need a drill bit. Don't you know if I'm ready? "

"Don't worry, Comrade Chen. We've already prepared the drill bit. It's used to drill wells. It's not a problem if it can drill tens of meters deep." The political commissar made a promise and banged his chest.

Chen Xinjian knew all about the situation, so he didn't say anything more. He just said that he wanted to see the situation of the installation site.Of course, the political commissar would not object. He personally took Chen Xin to the place where he planned to install the computer room in the future, and also called an engineer.

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

Chen Xin checks the room and takes out a tape measure to measure the data.

While busy, Chen Xin also expressed curiosity about the two huge cylindrical water tanks placed in the 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 it here to collect and store the heat, and then use it for heating." The engineer explained that he seemed to have an inexplicable worship for Chen Xin.

In the end of the world, people who can produce a ground source heat pump by hand with only waste air conditioners are really powerful for people who understand the difficulty of machining and manufacturing, and it's not surprising that they have a feeling of worship.

However, after listening to the engineer's words, Chen Xin nodded and said: "this is not necessarily true. For a private shelter with such an energy storage tank, besides heating, it also means 24-hour hot water. Even if the equipment is shut down, there will be enough hot water in it for a while. "

When Chen Xin said that, the engineers showed great interest and talked with Chen Xin about the technical problems of ground source heat pump equipment.
