Compared with manufacturing ten 10kW small equipment, three 50KW large equipment is obviously stronger in the overall output power.

Another advantage of large equipment is that although the output power of a large equipment is the same as that of five small equipment, the power consumption of large equipment is obviously lower at the same output power.

The manufactured equipment did not appear on Chen Xin's worktable, but directly exported to the upper material warehouse.

This is undoubtedly one of the new functions after the upgrade. Chen Xin can choose to make the manufactured items appear on the workbench, or he can also choose to put the items directly into the material warehouse, so as to avoid some items occupying the internal space of the main body of the refuge.

The manufacturing time of three large-scale ground source heat pumps is much shorter than that of ten small-scale ground source heat pumps originally expected by Chen Xin.

According to Chen Xin's last time of manufacturing ground source heat pumps for the special police force, he can probably complete three small ground source heat pumps in one day, but now he has finished manufacturing three large ground source heat pumps in about one noon and afternoon.

This is undoubtedly a major positive for Chen Xin.

Originally, he needed to manufacture 50 sets of small-scale ground source heat pump equipment. Now he has replaced them with large-scale ground source heat pump equipment. With the same total output power, Chen Xin has completed nearly one-third of the task requirements with one-fifth of the original materials and less than one-fifth of the construction period.

You know, Chen Xin's original calculation was that ten small devices could be upgraded in two to three days. Now it took only one day to complete all of them, and there was a little surplus in the materials. For Chen Xin, it saved him a lot of time, and he could start a few days earlier than expected.

The result was reported to the people contacted by the municipal government through the short wave radio station. Sure enough, after learning the news, the municipal government also showed great joy and interest.

After all, people in the municipal government can tell which one is easy to maintain and use, ten or three.

Moreover, Chen Xin is able to manufacture large-scale ground source heat pump equipment, which is also a very significant good news for the city government's plan to reopen small shelters.

If it is not for the city government's original plan to use ground source heat pump heating in a small shelter as a pilot, and then decide whether to use more small shelters according to the effect, the leaders in charge of this matter are going to ask Chen Xin to order more equipment, so as to reopen all the small shelters that were sealed up in the urban area.

But after all, it's the leader. He doesn't have such an impulse to do things. Besides, Chen Xin also says that he needs to go back to his hometown to pick up his parents. It's not easy for people in the city government to change their plans and force Chen Xin to stay.

Therefore, the leader of the municipal government in charge of this matter just asked people to send the manufacturing materials discussed before to Chen Xin's refuge, and at the same time, three large-scale ground source heat pump equipment were received and sent to the small refuge to be opened.

As for the installation of ground source heat pump, Chen Xin or the leaders don't need to worry about it. Naturally, there is a municipal construction team to deal with this kind of thing. Chen Xin only needs to be responsible for providing equipment, while the leaders only care about the results.

As things go smoothly, Chen Xin naturally doesn't worry about it any more. Next, he just needs to use the materials provided by them to complete the production of ground source heat pump according to the requirements of the municipal government.

In addition, what Chen Xin needs to worry about is how to transfer his refuge to Mo Qingyan and Mo Qingxin before he leaves.

Chen Xin has negotiated with Mo Qingyan about this matter, and she has agreed to come back to take care of Chen Xin's shelter, but for the time being, she and Mo Qingxin have not moved here.

However, Mo Qingyan also agreed that she would move in two days before Chen Xin's departure, so as to set aside enough time to get familiar with Chen Xin's refuge, so that she would not use the equipment in his refuge after Chen Xin left, causing any unnecessary trouble.

In addition to these things, Chen's vegetables in the greenhouse are about to be harvested, which means that the monthly material exchange with the SWAT team is approaching.

It's just that the materials from the special police team had been sent to him by the city government before, but the vegetables from Chen Xin's side had not yet reached the harvest time, so this material exchange was just Chen Xin's unilateral delivery of the harvested vegetables to the special police team.

And this kind of thing because Chen Xin had advanced the exchange share of the next two months, and he had to do it twice before he could exchange materials again.

According to Chen Xin's own estimate of time, if everything goes well, by that time he will have picked up his parents from his hometown.

So after thinking about it for a while, Chen Xin decided that Mo Qingyan would be in charge of this material exchange and the next two material exchanges, while he could leave a few days in advance and go back to his hometown early.

Fortunately, now his greenhouse has been fully mechanized, and both sowing and harvesting can be done by machines. Mo Qingyan only needs to operate on the console, and she doesn't really need to do farm work like Chen Xin did before.While thinking about these things, Chen Xin also came to the planting greenhouse, came to the console, and checked the growth of crops in the greenhouse through the monitor screen.

After the upgrade of the greenhouse, the console is a very convenient tool. Through the monitor screen on the console, Chen Xin can see the growth of each crop on the six layers of hydroponic cultivation tray above his head, without climbing up for visual inspection.

Examining the crops that are about to mature, Chen Xin suddenly noticed that on one layer of hydroponic cultivation plate, there is a small piece of crops that is different from other crops. It looks like a pile of weeds.

Chen Xin drew the camera closer, and then he realized that this was the herb he had promised to plant for Dr. Hongrui.

Chen Xin planted them before and took care of them later. However, it is obvious that so many things happened during this period that Chen Xin himself has forgotten that he also planted these herbs.

The growth of these herbs is quite good, but as medicinal materials, they don't grow as fast as the vegetables on the side. It will take some time to cultivate them before they can be picked.

After checking these herbs, Chen Xin didn't care too much. The herbs are growing well at present, and it's still early to pick them, so he didn't care too much.

Just looking at these herbs, he thought of something he had ignored.

That is, although he prepared a first-aid kit on the armored RV, he did not prepare enough medicine.

It's not that Chen Xin forgot to prepare the medicine. Before, he took all kinds of medicine from the medical room and put it in the medicine box of the armored RV.

Not only medicine, but also a simple operation bag that can be used for emergency operation. Chen Xin has prepared two to avoid accidents on the road.

However, these drugs were prepared before the disaster, and the types were limited to some common drugs. In addition, Chen Xin had to leave some of them in the shelter, so although it was not enough, it might not be enough in case of some accidents.

"It seems that we have to find a way to get some medicine!" Chen Xinmo rubbed his chin, seriously thinking about what medicine he would like to prepare: "unfortunately, something happened at the doctor's home, otherwise he would be a good place to change his dressing. Now he is on Bruce Lee's side, I can't find him to change his dressing."

It's not that Chen Xin thinks there's something wrong with going to Li Yulong's place to change the medicine. Instead, he goes to the doctor to change the medicine, which is bound to let Li Yulong know about it. If Li Yulong knows about it, I'm afraid the medicine will not be changed because of his personality.

Although Li Yulong asked Chen Xin for help, Chen Xin did help him, but on the whole, Chen Xin still owes Li Yulong the favor. Even if he wants to collect wool, he can't always collect it on Li Yulong alone.

What's more, it's not easy to repay the debt of human relations. When there are many such things, they will affect the relationship between Chen Xin and Li Yulong.

So there's no need. Chen Xin prefers to go to the hospital through the municipal government to exchange some drugs for use on the road.

And there is also an advantage to this, that is, the doctors in the hospital are obviously more professional, and the prepared drugs are more able to cope with various situations.

Now that we have thought of the lack of preparation, we should make up for it immediately.

Chen Xin didn't delay. When the staff of the municipal government came to deliver the second batch of materials and towed away the three large ground source heat pump equipment, Chen Xin also mentioned that he needed a batch of drugs with the person in charge of delivering the materials.

This person in charge is to replace Secretary Li, who is mainly responsible for the handover of materials and equipment with Chen Xin.

After listening to Chen Xin's request, he agreed to help Chen Xin contact the hospital and ask the hospital to prepare a batch of drugs for him. He even took the initiative to invite Chen Xin to go back to the city with him and go directly to the hospital to get the drugs.

Naturally, after completing the handover of materials and equipment, Chen Xin and the person in charge went back to the city in the municipal government's car.

When he came to the hospital, the person in charge went to the people in the hospital to help Chen Xin mix drugs, while Chen Xin was bored and sat in the hall of the hospital waiting.

There is still no big difference between the hall of the hospital and before. Although it is the end of the world, it is also a hospital transformed from a refuge, but there is also an endless stream of patients as before the disaster.

But Chen Xin can't take out his mobile phone to play games as before. He can only sit idly watching "cat and mouse" on the TV in the hall.

Just when Chen Xin felt bored and was about to yawn, a cry full of surprise came from behind: "little Chen Xuedi?"

Chen Xin was also a little surprised. In his impression, only one person would call him that name.

As he looked back, he stood up from his chair. The man who appeared in front of him was the one who would call him like this: "Xuejie?"
