Doomsday Bunker Upgrade Chapter 149: Go home

"I can upgrade the shelter ()" to find the latest chapter!

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

Even if you need to wait for the construction of the cement to dry out, there is not much time wasted. After three days, the whole set of equipment can be operated smoothly.

However, the equipment is only for trial operation, because the SWAT team has not yet 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 operating conditions of the equipment.

"The operation of the equipment is no problem, but whether it can run for a long time is still unknown. My suggestion is to connect the pipeline to the hot water pipeline in the bathroom, so that you can first test whether the heating and operation are stable." Chen Xin suggested to the engineer beside him.

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 the heat exchange.

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

The engineer looked at the water level displayed on the energy storage tank and calculated the heating efficiency of the six ground-source heat pumps. He nodded with satisfaction and said: “Calculated based on the current operating data, the six ground-source heat pumps can be It can provide 2 tons of hot water within an hour, which is quite efficient!"

The engineer was visibly excited when it came to this data.

Although I know that the thermal efficiency of the ground source heat pump is very high, but in half an hour, the energy storage tank that can hold 5 tons of water has been filled by one-fifth, which is still obvious. Excited, especially since he was involved in installing the equipment.

So watching the equipment run so well gave the engineers a sense of accomplishment.

In response to the engineer’s excitement, Chen Xin also laughed, but he continued: “Now because it’s just a test, I haven’t set the operating power of the equipment to its maximum. The pipes are connected to provide hot water to the bathroom and test the stability of the equipment's maximum power and long-term operation.

In the final analysis, this set of equipment is just made by myself. I can't guarantee the stability of operation. It is 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. Are you going back?"

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

"Oh, that's time to go back and see." When Chen Xin said this, the engineer felt that he had no reason to stay.

Although I think Chen Xin should go back, the engineer still asked worriedly: "If there is any problem with the equipment in the future, will you come over Chen Gong?"

"Please rest assured that if there is any malfunction in the operation of the equipment, the SWAT team knows where my home is, and I can come over at any time." Chen Xin readily made a guarantee when it came to after-sales issues.

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

"Axin, are you going back now?" Qin Lan looked at Chen Xin next to her, feeling a little bit disappointed.

In the past few days, I have lived with Chen Xin again. In close contact, Qin Lan feels as if she is in love with him again, and feels a little bit uncomfortable for Chen Xin's departure.

Chen Xin saw Qin Lan's emotions, but he was unintentionally reunited with Qin Lan, and it was not suitable for him to be too intimate with Qin Lan at this time.

Although he and Qin Lan have recovered to the same level of closeness as they used to be these days, Chen Xin knew that even Qin Lan didn't mean to get back together, otherwise she would have spoken.

So even though he saw that Qin Lan's mood was a little wrong, he could only nod Qin Lan and said, "Well, it's time to go back. The greenhouse at home hasn't been taken care of these days, and I don't know what it's like. I have to clean up when I go back."

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

He turned on the ground source heat pump and generator before going out, so there is no danger of power outage.

As long as there is no power failure in the planting greenhouse, the water and heating will not be stopped. No matter what happens for a few days, nothing will happen.

But you still have to take care of the vegetables regularly, especially the first batch of upland rice he planted should be harvested this month, and he has to go back to harvest the rice.

Qin Lan naturally knows this too. Although she is a little reluctant to leave Chen Xin, she nodded and said: "Then Axin, be careful, I will be on duty today~IndoMTL.com~Let Aning send you back."

"Xiao Ding? I haven't seen her in the past few days. Is she back?" Although Chen Xin was a little surprised that Qin Lan sent herself back, he still understood what she meant. He didn't say anything, just curious. Why haven't I seen Ding Ning these days.

"A Ning has been on duty in other shelters these days, and only came back today in shifts." Qin Lan explained why he hadn't seen Ding Ning these days, and brought Chen Xin back to the room to help him pack his luggage. , but did not send Chen Xin 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 behind him, but he didn't look back, just sighed and left the shelter in the elevator.

Accompanied 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 clean up his shelter.

I've been away from 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 these days and has been exposed to light, the growth is better than before.

The only thing that made Chen Xin bothersome was the small bunker where he placed the antenna. Thick ice accumulated here, and even the gap with the outside world was completely blocked. Just breaking the ice is a laborious task. .
