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 very friendly smile: "Can I sit here?" ”

"There's no one here, you can sit casually, political commissar." Qin Lan hurriedly beckoned the political commissar to sit down, and Chen Xin on the side also nodded and said hello.

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 window of the cafeteria 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, he did not have too many superfluous greetings, and quickly turned the topic to the main topic: "I don't know if there is anything that needs our cooperation?" We must do our best to cooperate. ”

"In terms of cooperation, the main thing is where are you going to install the equipment? And how are you going to install it? Chen Xin heard the political commissar ask, and he was not polite: "The installation of ground source heat pump is different from other equipment, and the heat exchange pipe needs to be buried deep underground, so it is necessary to carry out drilling operations, and it also needs to have a suitable installation site."

As for the plumbing and heating arrangement, this is what you plan yourself, and I am only responsible for the installation, operation and commissioning of the equipment. ”

The political commissar nodded understandingly, although Chen Xin was responsible for the door-to-door installation, but the two sides neither communicated the actual situation on the site, nor did they use the demand, but only sent a few recycled waste air conditioning outdoor units, Chen Xin pulled over six renovated ground source heat pumps, to say that Chen Xin can know how to install it, it is completely coaxing.

However, the commissar was not unprepared for this issue.

The official shelters are better than the dead people's shelters because they are so numerous that they can find enough people and professionals to do whatever they want.

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 problem, it may be possible to use shallow geothermal energy for heating in a year and a half, so there is no problem in finding a professional to do the installation planning of heating pipes and equipment.

"In this regard, we have found a professional designer to do project planning, and the design drawings have also been released, but the main difference is the equipment specifications and models and pipeline diameters on your side, Comrade Xiao Chen." The political commissar was very happy to introduce the situation to Chen Xin, and said that the drawings were in the conference room of the special police team, and Chen Xin could go to see them after eating.

Chen Xin nodded knowingly, and replied affirmatively: "Since there are drawings, it's much easier to say, so let's go to see the drawings first after eating." ”

Hearing Chen Xin say this, the political commissar naturally did 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 dinner? ”

"A-Ning has a mission today, and he is on duty outside now, and he will come back in the evening." Uncle Ding didn't feel strange that Chen Xin asked Ding Ning, but just explained: "Now the city bureau is short of manpower, even my daughter is nothing special, she has 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, there is no problem for Uncle Ding to fight for some preferential treatment for his daughter, but in the end, this is a family matter and an internal affair of the SWAT team, and Chen Xin has no way to beak.

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

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

Especially in the past two days, she took leave to live with Chen Xin, although there was a valid reason, but the work was still delayed a lot.

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

"Are you planning 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 pipeline layout design above, and did not propose modifications, but nodded: "There is no problem with this layout, but the equipment I brought is not prepared with so many pipes, which requires you to piping yourself, and the radiator itself, which is not included in the ground source heat pump equipment, and I am not responsible for installation." ”

"Of course, we have prepared these things, as long as we have confirmed the pipe diameter of the ground source heat pump equipment manufactured by Comrade Xiao Chen, we can complete the pipeline." The commissar gave affirmative assurances.

Chen Xin didn't say much about this, but said to them: "In this case, I need to go to see the actual situation of the installation site, and the installation of heat exchange pipes needs to be punched." I told you that I need a drill bit, I don't know if I'm prepared? ”

"Comrade Xiao Chen, don't worry, we have already prepared the drill bit, it is a drill bit used to drill wells, and it can drill dozens of meters deep." The political commissar slapped his chest with a bang on the ticket.

Chen Xin saw that the situation was already understood, so he didn't say anything, but said that he wanted to go to see the on-site situation at 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 set aside room, and the six ground source heat pump equipment sent by Chen Xinhao are also temporarily placed here.

Chen Xin checked the situation in the room, and took out a tape measure to measure the data in a matter-of-fact manner.

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?" ”

"It's a thermal energy storage tank, which may not be needed in private shelters, but we need to use it here to collect and store thermal energy and then use it for heating." The engineer explained that he seemed to have an inexplicable admiration for Chen Xin.

In the apocalyptic environment, it is not surprising that a person who can make a ground source heat pump with only a waste air conditioner outdoor unit is very powerful for people who understand the difficulty of machining and manufacturing.

However, after listening to the engineer's words, Chen Xin also nodded and said: "This is not 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 24-hour hot water." Even if the equipment is shut down, the hot water stored in it will be enough for a while. ”

Seeing Chen Xin say this, the engineer was very interested, and chatted with Chen Xin about a lot of technical issues about ground source heat pump equipment.
