With professional construction workers and engineers assisting, the six ground source heat pumps provided by Chen Xin to the SWAT team were quickly and smoothly installed.
Even though it was necessary to wait for the construction cement to dry, not much time was wasted. After three days, the entire equipment was running smoothly.
However, the equipment was only in trial operation, because the SWAT team had not yet connected the equipment to the heating equipment in the area where the SWAT team was located, so Chen Xin just started the equipment and tested its operation.
"There is no problem with the operation of the equipment, but it is still unknown whether it can run for a long time. 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 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 six ground source heat pumps, this energy storage tank is already less than 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 operating data, the six ground source heat pumps can heat the water within an hour. Providing 2 tons of hot water, this efficiency is quite high! ”
Speaking of this data, the engineer was visibly excited.
Although we know that the thermal efficiency of ground source heat pumps is very high, seeing with your own eyes that the energy storage tank that can hold 5 tons of water has been filled to one-fifth in half an hour is still obviously exciting, especially He was involved in installing this equipment.
So seeing the equipment operating in such excellent condition gave the engineer a sense of accomplishment.
Chen Xin also laughed at the engineer's excitement, but he continued: "Because it is just a test, I have not turned the operating power of the equipment to the maximum. I suggest you connect the energy storage tank to the hot water pipe in the bathroom. , which can not only provide hot water for the bathroom, but also test the stability of the long-term operation of the maximum power of the equipment.
After all, this set of equipment is just made by myself. I can't guarantee its operational stability. It's better to test it. "
"Indeed, the key is long-term stable operation of the equipment. We will modify the pipeline for testing." The engineer also agreed with Chen Xin's words. After nodding and writing it down, he asked Chen Xin with concern: "Mr. Chen, are you going back? ?"
Chen Xin did not deny it, but just nodded: "The equipment has been installed and there is no problem running it now, so I will go back tomorrow. There are still vegetables growing in the greenhouse at home. I am a little worried after not taking care of it for a few days."
"Oh, it's time to go back and take a look." After hearing what Chen Xin said, the engineer felt that he had no reason to stay.
However, although he felt that Chen Xin should indeed go back, the engineer still asked worriedly: "If there are any problems with the operation of the equipment in the future, will you still come over then, Mr. Chen?"
"Don't worry about this. 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." Regarding after-sales issues, Chen Xin readily made the guarantee.
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.
"A Xin, are you going back now?" Qin Lan looked at Chen Xin beside him, feeling a little reluctant.
In the past few days, she and Chen Xin have lived together again. Under the close contact, Qin Lan felt as if she had fallen in love with him again, and she was also a little uncomfortable with Chen Xin's departure.
Chen Xin saw Qin Lan's emotions, but he had no intention of getting 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 returned to the same close relationship as before these days, Chen Xin knows that even Qin Lan has no intention of getting back together, otherwise she would have spoken long ago.
So even though he could see that something was wrong with Qin Lan's mood, he could only nodded to Qin Lan and said: "Well, it's time to go back. No one has taken care of the greenhouse at home these days. I don't know how bad it is. I still need to go back." Clean it up."
Chen Xin was not that worried about whether there would be problems in the greenhouse after not going back for so many days.
He had turned on the ground source heat pump and generator before going out, so there was no risk of a power outage.
As long as there is no power outage in the greenhouse, the water and heating will not be cut off, so there will be no problem if it is left alone for a few days.
But planting vegetables still requires regular care, especially since 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 knew this. Although she was a little reluctant to leave Chen Xin, she still nodded and said: "Then A Xin, be careful yourself. I have to be on duty today, so let An Ning take 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 it wasn't Qin Lan who was sending him back, he understood what she meant and didn't say anything more. He was just curious about the past few days. Why didn't I see Ding Ning
"A Ning has been on duty at another shelter these days and just came back from his shift today." Qin Lan explained why she hadn't seen Ding Ning in the past few days. After taking Chen Xin back to the room to help him pack his luggage, Qin Lan didn't Chen Xin was not sent away.
Looking at Chen Xin's leaving figure, Qin Lan felt uncomfortable for some reason. The last time this feeling occurred was when she and Chen Xin broke up.
Chen Xin knew that Qin Lan had been looking at him from behind, but he did not look back. He just sighed and left the shelter in the elevator.
Under the escort of Ding Ning and another SWAT team member, Chen Xin returned to his home where he had been away for several days.
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 shoveling away the snow.
Ding Ning and another SWAT team member did not stay long. They just dropped Chen Xin off and left, while Chen Xin began to pack up his shelter.
After being away from home for a few days, although everything is still clean and the floor does not need much sweeping, there is still some dust.
As for the water circulation system, since Chen Xin is not at home these days, there is no need to clean it if it is not in use.
The conditions in the greenhouse are also good. The crops are not only growing normally, but because Chen Xin has not turned off the fill light these past few days and has been exposed to sunlight, the growth is better than before.
The only thing that troubled Chen Xin was the small bunker where he placed the antenna. Thick ice accumulated here, and even the gaps connecting to the outside world were completely blocked. Just breaking the ice was a laborious task. (End of chapter)
