Chapter 150

With professional workers and engineers, the six ground source heat pumps Chen Xin provided to the special police team were successfully installed.

Even if we need to wait for the cement to dry completely, we don't waste too much time. After three days, the whole set of equipment can run smoothly.

However, the equipment is only for trial operation. Because the special police team has not yet connected the equipment with the heating equipment in the area where the special police team is located, Chen Xin just started the equipment and tested its operation.

"There is no problem with the operation of the equipment, but whether it can run for a long time is still unknown. My suggestion is to connect the line with the hot water line in the bathroom, so that we can test whether the heating and operation are stable first. " Chen Xin proposed 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 stored in the energy storage tank in the form of hot water after heat exchange.

But the capacity of the energy storage tank is limited. Under the continuous operation of six ground source heat pumps, the energy storage tank has been half full.

Looking at the water level displayed on the energy storage tank, the engineer calculated the heating efficiency of the six ground source heat pumps, nodded his head and said, "according to the current operation data, the six ground source heat pumps can provide 2 tons of hot water in an hour, and the efficiency has been quite high!"

Speaking of this data, engineers are obviously excited.

Although we know that the thermal efficiency of ground source heat pump is very high, it is still very exciting to see that in half an hour, the energy storage tank that can hold 5 tons of water has been filled up by one fifth. In particular, he participated in the installation of this set of equipment.

So looking at the equipment running so well, the engineers are also full of a sense of achievement.

For the excitement of the engineer, Chen Xin also laughed, but he continued: "now because it's just testing, I didn't turn on the maximum power of the equipment. I suggest you connect the energy storage tank with the hot water pipe of the bathroom, so that you can provide hot water for the bathroom and test the stability of the maximum power long-term operation of the equipment.

After all, this set of equipment is only made by myself. I can't guarantee the stability of operation. It's better to test it. "

"It's true that long-term smooth operation of the equipment is the key. We will transform 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: "Chen Gong, are you going back?"

Chen Xin didn't deny it, but nodded: "the equipment has been installed, and now it's running smoothly, so I'll go back tomorrow. My greenhouse is still growing vegetables. I'm a little worried that I haven't taken care of it for a few days."

"Oh, it's time to go back and have a look." After listening to what Chen Xin said, the engineer also felt that he had no reason to stay.

However, although Chen Xin felt that it was time to go back, the engineer was still worried and asked, "if there are any problems in the future operation of the equipment, will Chen Gong come back then?"

"Please rest assured that if there is any fault in the operation of the equipment, the special police team knows where my home is, and I can come at any time." It's about after-sales, Chen Xin is very straightforward to make a guarantee.

After chatting with the engineer about the operation and maintenance of the equipment for a while, Chen Xin turns around and leaves, while Qin LAN is already waiting for him.

"Ah Xin, are you going back now?" Qin LAN looks at Chen Xin beside him, can't help but give up.

These days, she lives with Chen Xin again. In close contact, Qin LAN feels as if she has fallen in love with him again, and she feels a little uncomfortable about Chen Xin's departure.

Chen Xin sees Qin Lan's emotion, but he doesn't want to compound with Qin LAN. At this time, he is not suitable to be too close to Qin LAN.

Although these days he and Qin LAN have returned to the same level of intimacy as in the past, Chen Xin knows that even Qin LAN doesn't mean to get back together, otherwise she would have spoken.

So although Qin Lan's mood is not right, he can only nod his head to Qin LAN and say, "well, it's time to go back. Nobody takes care of the greenhouse these days. I don't know how bad it is. 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 so many days' absence.

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

As long as there is no power cut, the water and heating will not stop for a few days.

However, he has to take care of all kinds of vegetables, especially the first batch of upland rice he planted should be harvested this month, and he has to go back to collect rice.

Qin LAN naturally knows these, although a little reluctant to leave Chen Xin, but still nodded and said: "ah Xin, be careful yourself, today I will be on duty, let ah Ning send you back."

"Xiaoding? I haven't seen her these days. Has she come back? " Although Chen Xin was surprised that Qin LAN didn't send her back, she also understood what she meant and didn't say much. She was just curious why she didn't see Ding Ning these days."Ah Ning has been on duty in other shelters these days, and he only came back on duty today." Qin LAN explains why he didn't see Ding Ning these days. After taking Chen Xin back to his room to help him pack, he didn't send Chen Xin away.

Looking at Chen Xin's back, Qin LAN doesn't know why she feels uncomfortable. The last time this feeling appeared, it was when she broke up with Chen Xin.

Chen Xin knows that Qin LAN is looking at him all the time, but he doesn't look back. He just sighs and leaves the shelter in the elevator.

Under the escort of Ding Ning and another special police member, Chen Xin returned to his home where he had been away for several days.

The door is still covered with snow. With the help of Ding Ning and another special police member, Chen Xin was able to enter the door after shoveling away the snow.

Ding Ning and another member of the special police force did not stay long. They just sent Chen Xin to the police station and left, while Chen Xin began to clean up his shelter.

A few days away from home, although everywhere is still clean, the ground does not need how to sweep, but more or less fell some dust.

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

The situation in the greenhouse is also good. The crops not only grow normally, but also grow better than before because Chen Xin hasn't turned off the fill light these days.

The only thing that bothers Chen Xin is the small shelter where he put the antenna. There is thick ice here, and even the gap between him and the outside world is completely blocked. It's a hard work just to break the ice.
