With professional workers and engineers on the side, Chen Xin's six ground source heat pumps provided to the SWAT team were quickly and smoothly installed.

Even if it was necessary to wait for the cement to dry out, it did not waste too much time, and after three days, the whole set of equipment was running smoothly.

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

"There is no problem with the operation of the equipment, but it is not yet known whether it will be able to run for a long time. My suggestion is to connect the line to the hot water line in the bathroom, so that you can test whether the heating and operation are stable first. Chen Xin proposed to the engineer beside him.

Since the ground source heat pump is not connected to the heating line, 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, and with the continuous operation of six ground source heat pumps, the energy storage tank is already 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 and said: "According to the current operation data, the six ground source heat pumps can provide 2 tons of hot water within an hour, which is quite high!" ”

Speaking of this data, the engineers are visibly excited.

Although he knew that the thermal efficiency of the ground source heat pump was very high, it was still obvious to see that in half an hour, the energy storage tank that could hold 5 tons of water had been filled to a fifth, especially since he was involved in the installation of this set of equipment.

So seeing the equipment running so well, the engineers are also full of a sense of accomplishment.

Chen Xin also laughed at the excitement of the engineer, but he continued: "Now because it is only a test, I have not turned on the operating power of the equipment to the maximum, and it is recommended that you connect the energy storage tank with the hot water pipe in the bathroom, so that you can provide hot water for the bathroom at the same time, and also test the stability of the long-term operation of the maximum power of the equipment."

In the end, 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 key is the smooth operation of the equipment for a long time, and we will modify the pipeline for testing." The engineer also agreed with Chen Xin's words, nodded and wrote them down, and then asked Chen Xin with concern: "Chen Gong, are you going back?" ”

Chen Xin didn't deny it, just nodded: "The equipment has been installed, and there is no problem with running now, so I'll go back tomorrow, I still grow vegetables in the greenhouse at home, and I'm a little worried about not taking care of it for a few days." ”

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

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

"Rest assured, 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." When it comes to after-sales issues, Chen Xin made a guarantee very happily.

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

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

In the past few days, he has lived with Chen Xin again, and under the intimate contact, Qin Lan feels as if he is in love with him again, and he is also a little uncomfortable with Chen Xin's departure.

Chen Xin saw Qin Lan's emotions, but he had no intention of reuniting with Qin Lan, and he was not suitable to be too intimate with Qin Lan at this time.

Although he and Qin Lan had returned to the same intimate relationship as in the past these days, Chen Xin knew that even Qin Lan herself had no intention of getting back together, otherwise she would have spoken a long time ago.

So although he could see that Qin Lan's mood was a little wrong, he could only nod to Qin Lan and say, "Well, it's time to go back, no one has taken care of the greenhouse at home for the past few days, and I don't know what has become bad, and I have to clean it up when I go back." ”

Chen Xin is not so worried about whether there will be problems in the greenhouse after not going back for so many days.

He had already turned on the ground source heat pump and generator before he went out, so that there was no danger of power outage.

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

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

Qin Lan naturally knew this, although she was a little reluctant to let Chen Xin go, she still nodded and said, "Then Ah Xin, be careful yourself, I still have to be on duty today, let Ah Ning send 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 didn't send him back, he also understood what she meant, and didn't say anything, just curious why he hadn't seen Ding Ning in the past few days.

"A-Ning has been on duty in other shelters for the past few days, and he only came back from his shift today." Qin Lan explained the reason why she hadn't seen Ding Ning in the past few days, and after taking Chen Xin back to the room to help him pack his luggage, she didn't send Chen Xin away.

Looking at the back of Chen Xin leaving, Qin Lan didn't know why she felt uncomfortable in her heart, the last time this feeling appeared, it was when she broke up with Chen Xin.

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.

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

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

Ding Ning and another SWAT team member did not stay long, but just sent Chen Xin and left, while Chen Xin began to pack up his shelter.

I was away from home for a few days, although everything was still clean and the floor didn't need to be swept much, but some dust still fell some.

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

The situation in the planting greenhouse is 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 the irradiation, the growth is better than before.

The only thing that troubled Chen Xin was the small bunker where he had placed the antenna, where there was a thick layer of ice, and even the gaps connecting with the outside world were completely blocked, and just breaking the ice was a laborious job.
