Doomsday Bunker Upgrade Chapter 121: Large equipment (7/10)

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

Although every part of a bunch of parts had to be brushed, with Qin Lan's help, the two of them worked together and quickly washed all the parts and threw them in the water.

"Is it okay to just soak in this way? Axin, did you not add detergent?" Qin Lan watched Chen Xin soak all the parts in water, and confirmed to him with concern.

Chen Xin nodded and replied affirmatively: "So soaking is enough. Unfortunately, there is no kerosene. Otherwise, kerosene will work best."

"Then what are you doing now?" Taking off the gloves and putting them aside, Qin Lan looked at Chen Xin and waited for him to speak.

Chen Xin felt a little embarrassed by Qin Lan's gaze, and after clasping his face with his fingers, he said, "If I said to continue playing games, would you beat me?"

"..." Qin Lan looked at Chen Xin silently, and then said after a while: "No, you can do whatever you want with Axin. But I still think you should find something to do. Playing games is not Puts you in a good mood."

Qin Lan's words made Chen Xin smile, but he didn't say much, he just nodded and said: "In this case, Alan, please continue to help, help me assemble the ground source heat pump. Uncle Ding asked you to send it. So many outdoor air conditioners come here to change ground source heat pumps from me? How many do you need?"

"Axin, how much material do you need to make a ground source heat pump? How large is the heating range?" Qin Lan didn't talk about her needs first, but asked Chen Xin for relevant data about the ground source heat pump.

"You can make a ground source heat pump with materials removed from an external unit of an air conditioner. The effective heating range is about 100 square meters. As for the specific data, I don't have tools to measure it. That's it. "Although there is a system, this system does not have any data panels, so Chen Xin does not know much about the equipment he made: "The thermal efficiency of the ground source heat pump is about twice that of the air conditioner at the same power. By calculation, you should be able to roughly get the heating effect of a ground-source heat pump. If used in a confined space, the effect should be good."

Through Chen Xin’s explanation, Qin Lan roughly understood the performance of the ground-source heat pump produced by Chen Xin, and knew in her heart, so she said to Chen Xin: “I’ve brought eight air conditioners this time. If you can, I hope you can make at least six pieces of equipment. If another piece of equipment is made with two outside air conditioners, can it improve the heating effect?"

Before I came here, the political commissar deliberately raised this issue with Qin Lan. The SWAT team did not want to say that eight sets of materials should be replaced with eight sets of equipment.

The eight external air conditioners were replaced by six devices, and the other two external air conditioners were Chen Xin’s labor costs. This was the result of discussions between Ding Shu and the political commissar.

They still have some doubts about the heating effect of the ground source heat pump. Before Qin Lan came, the political commissar also specially explained that she asked Chen Xin for more information about the performance of the ground source heat pump, so as to understand the ground source heat pump as much as possible. Specific heating effect.

But when Qin Lan entered Chen Xin’s refuge, she had no doubts about it. Although Chen Xin’s refuge was only a private refuge and the place was not large, it was two to three hundred at a glance. The square is still there. The heat provided by such a large area of ​​ground source heat pump equipment can keep the temperature at about 20°C, and the effect is already very good.

"Using two? Do you mean connecting devices in parallel to improve the heating effect of a single device?" As soon as Qin Lan said, Chen Xin understood her meaning and nodded and said: "Of course you can do it. Combining the equipment into one can indeed improve the heating effect, do you need a high-power ground source heat pump?"

For this question, of course Qin Lan gave a positive answer: "The area where the SWAT team is located is not small. Even if it only heats the main district, it needs high-power equipment to meet the heating demand. And if there are high-power equipment, we The heat can be distributed to more rooms with pipes, so that more people can be heated.”

"In other words, you want to use ground source heat pump equipment to build a heating system?" Chen Xin understood Qin Lan's meaning when he heard it.

For places with large heating requirements such as official refuges, the centralized use of multiple devices, and the concentrated heat energy provided by the devices, is distributed to more areas through pipes, which is indeed better than using separate devices. The heating effect is good.

When multiple devices work together, more heat can be obtained, and the heating effect is of course better than that of a single device.

"Axin, can you do it?" Qin Lan asked with concern when seeing Chen Xin understand what she meant.

What she asked was of course not the larger ground source heat pump equipment that Chen Xin had already answered, but the heating system based on ground source heat pump equipment.

Chen Xin thought for a moment, and after a simple simulation of the entire system in his mind, he said: "Of course you can do it~IndoMTL.com~ But it requires more materials and parts. High-power equipment does not mean putting a bunch of small The power equipment can be combined together, and it is better to have matching parts.

And if you want to do this kind of large-scale heating system, it is not only enough to have ground source heat pump equipment. Pipes, heat sinks, booster pumps... There are a lot of things that I have not gotten, and maybe you need professionals. help. "

Qin Lan is not surprised at all about this. After all, Chen Xin said that although he had done mechanical equipment work back then, his hands-on skills are indeed very good. He can DIY the ground-source heat pump equipment by himself and he is already quite good, but he is not after all. Professionals, let him make a heating system by himself, it is really too much for him.

If it weren't for the novelist's knowledge reserve as a bottomless pit, he had to know a little bit about everything, I'm afraid Chen Xin would not even be able to say what he needed to make a heating system.

"Professionals, Axin, you don't have to worry about it. This city has done a ground source heat pump for central heating project planning before. With experts in this area, you only need to be responsible for providing the equipment." Qin Lan settled down. Xinxinxin, this was also the research conducted by the former political commissar and Ding Shu when they decided to provide heating in the refuge area where the SWAT team is located.

If there is no professional theoretical support, they really dare not make a large-scale renovation of the shelter.

Ding Shu and the political commissar also found relevant experts to conduct theoretical verification before deciding on the ground-source heat pump equipment to centrally heat the area where the SWAT team is located.

"Since there are experts to guide me, then I don't have much to do. If you need more power equipment, just report the requirements to me." Chen Xin heard Qin Lan said that there were experts providing technical support, but he didn't bother much. What to say, just nodded and agreed to this matter.
