Doomsday Bunker Upgrade

With professional construction workers and engineers assisting, the six ground source heat pumps provided by Chen Xin to the SWAT team were quickly installed.

Even if it is necessary to wait for the cement to dry, it does not waste too much time. After three days, the whole set of equipment can run smoothly.

However, the equipment is only a trial operation, because the SWAT team has not connected the equipment to the heating equipment in the area where the SWAT team is located, so Chen Xin just started the equipment and tested the operation of the equipment.

"There is no problem with the operation of the equipment, but it is not known whether it can run for a long time. My suggestion is to connect the pipeline to the hot water pipeline of the bathroom, so that you can first test whether the heating and operation are stable." Chen Xinxiang The engineer beside him suggested.

Because the ground source heat pump equipment is not connected to the heating pipeline, the heat obtained by the ground source heat pump is now stored in the energy storage tank in the form of hot water after heat exchange.

However, the capacity of the energy storage tank is limited. With the continuous operation of the six ground source heat pumps, the energy storage tank is half full.

The engineer looked at the water level displayed on the energy storage tank, calculated the heating efficiency of the six ground source heat pumps, and nodded with satisfaction: "According to the current operating data, the six ground source heat pumps can be used within one hour. Providing 2 tons of hot water, this efficiency is quite high!"

When it comes to this data, engineers are clearly excited.

Although I know that the thermal efficiency of the ground source heat pump is very high, I can see with my own eyes that in half an hour, the energy storage tank that can hold 5 tons of water has been filled by one-fifth, which still makes people obviously excited, especially It is this equipment that he participated in the installation.

So watching the equipment run so well, the engineers are also full of a sense of accomplishment.

Chen Xin also laughed at the engineer's excitement, but he continued: "Because it's just a test, I haven't turned on the maximum operating power of the equipment, I suggest you connect the energy storage tank to the hot water pipe in the bathroom. , which can provide hot water for the bathroom, and also test the stability of the equipment's maximum power long-term operation.

In the final analysis, this equipment is just made by myself. I can't guarantee the stability of operation. It's better to test it. "

"Indeed, the long-term stable operation of the equipment is the key. We will renovate the pipeline for testing." The engineer also agreed with Chen Xin's words. ?"

Chen Xin didn't deny it, just nodded: "The equipment has been installed, and there is no problem with running it now, so I'll go back tomorrow. My greenhouse is still growing vegetables, so I'm a little worried if it hasn't been taken care of for a few days."

"Oh, it's time to go back and have a look." The engineer heard Chen Xin say this, and felt that he had no reason to stay.

However, although he felt that Chen Xin should go back, the engineer asked worriedly: "If there is any problem with the operation of the equipment in the future, will you still come over, Chen Gong?"

"Please rest assured. If there is any failure in the operation of the equipment, the SWAT team knows where my house is, and I can come over at any time." Regarding after-sales issues, Chen Xin readily assured.

After chatting with the engineer about equipment operation and maintenance for a while, Chen Xin turned to leave, and Qin Lan was already waiting for him.

"Axin, are you going back now?" Qin Lan looked at Chen Xin beside him and couldn't help but feel a little reluctant.

In the past few days, he and Chen Xin have been living together again. Under the close contact, Qin Lan felt as if he fell in love with him again, and felt a little uncomfortable about Chen Xin's departure.

Chen Xin could see Qin Lan's emotions, but he didn't want to get back together with Qin Lan, and it was not appropriate for him to be too intimate with Qin Lan at this time.

Although he and Qin Lan have recovered to the same level of intimacy as in the past these days, Chen Xin knows that even Qin Lan has no intention of getting back together, otherwise she would have spoken long ago.

So although he could see that Qin Lan was in a wrong mood, he could only nodded to Qin Lan and said, "Well, it's time to go back, the greenhouse at home has not been taken care of for the past few days, and I don't know what it's like, I still have to go back. Tidy up."

Chen Xin is not so worried about whether there will be a problem with the greenhouse if he hasn't gone back for so many days.

Before he went out, he had turned on the ground source heat pump and generator, and there was no danger of a power outage.

As long as the planting greenhouse is not powered off, the water and heating will not be stopped, and there will be no problems for a few days.

But he still needs to take care of the vegetables often, especially the first batch of upland rice he planted should be ready for harvest this month, and he has to go back to harvest the rice.

Qin Lan naturally knew this. Although he was a little reluctant to leave Chen Xin, he nodded and said, "Then Ah Xin, be careful yourself. I'm still on duty today. Let Aning take you back."

"Xiao Ding? I haven't seen her for a few days, is she back?" Although Chen Xin was a little surprised that Qin Lan sent him back, he understood what she meant and didn't say much, just curious these few days Why didn't I see Ding Ning.

"A Ning has been on duty in other shelters for the past few days, and only came back from shift today." Qin Lan explained why he hadn't seen Ding Ning these days. Chen Xin was not sent away.

Looking at the back of Chen Xin leaving, Qin Lan felt uncomfortable for a while. The last time this feeling appeared was when she and Chen Xin broke up.

Chen Xin knew that Qin Lan had been watching him from behind, but he didn't look back, just sighed and took the elevator to leave the shelter.

Escorted by Ding Ning and another SWAT team member, Chen Xin returned to his home after a few days' absence.

The door was still covered with snow. With the help of Ding Ning and another SWAT team member, Chen Xin was able to enter after the snow was shoveled away.

Ding Ning and another SWAT team member didn't stay long, they just sent Chen Xin and left, while Chen Xin started to pack up his shelter.

I haven't been at home for a few days. Although everything is clean and the floor doesn't need to be swept, there is still some dust.

As for the water circulation system, because Chen Xin is away from home these days, he doesn't need to clean it up if he doesn't use it.

The conditions in the planting greenhouse are also good. The crops are not only growing normally, but also because Chen Xin has not turned off the fill light in the past few days and has been exposed to light, the growth is better than before.

The only thing that bothered Chen Xin was the small bunker where he placed the antenna. Thick ice accumulated here, and even the gaps connecting with the outside world were completely blocked. Just breaking the ice was a laborious job.

After listening to everyone's opinions, since everyone thinks it's dull, let's skip this story.
