Although each of the pile of parts needed to be cleaned, with Qin Lan's help, the two of them quickly cleaned all the parts and threw them in the water to soak.
"Is it okay to just soak it like this? Ah Xin, didn't you add detergent?" Qin Lan looked at Chen Xin soaking all the parts in water and confirmed with him again with concern.
Chen Xin nodded and replied affirmatively: "Just soak it like this. It's a pity that there is no kerosene. Otherwise, kerosene would be the most effective."
"Then what are you doing now?" Taking off his gloves and putting them aside, Qin Lan looked at Chen Xin, waiting for him to speak.
Being stared at by Qin Lan, Chen Xin felt a little embarrassed. He slapped his face with his fingers and said, "If I tell you to continue playing games, will you beat me?"
"..." Qin Lan looked at Chen Xin silently, and after a while she said: "No, you can do whatever you want, A Xin. But I still think you should find something to do. Playing games will not make you happy. stand up."
Qin Lan's words made Chen Xin smile, but he didn't say anything more. He just nodded and said: "In that case, Alan, please continue to help me and assemble the ground source heat pump for me. Uncle Ding asked you to send so many Are you buying outdoor air conditioners from me for ground source heat pumps? "
"A Xin, how much material do you need to make a ground source heat pump? How big is the heating range?" Qin Lan did not tell her needs first, but just asked Chen Xin for relevant data about ground source heat pumps.
"A ground source heat pump can be made from materials dismantled from an air conditioner outdoor unit. The effective heating range is about one hundred square meters. As for the specific data, I don't have the tools to measure it. That's probably it." Although there is system, but this system does not have any data panel, 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 with the same power. Calculate based on this value, you 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 had a general understanding of the performance of the ground source heat pump made by Chen Xin, and she knew it in her mind, so she said to Chen Xin: "I brought eight outdoor air conditioners this time. If If possible, I hope you can make at least six devices, Axin. If the other device is made with two outdoor air conditioners, can the heating effect be improved? "
The political commissar specifically raised this issue with Qin Lan before coming. The SWAT team did not want to exchange eight sets of materials for eight sets of equipment.
Eight outdoor air-conditioning units were replaced by six units. The other two outdoor air-conditioning units were Chen Xin's labor cost. This was the result of discussions between Uncle Ding and the political commissar.
They still have some doubts about the heating effect of ground source heat pumps. Before Qin Lan came, the political commissar also specifically asked her to ask Chen Xin for more information about the performance of ground source heat pumps, so as to learn as much as possible about the specific heating effects of ground source heat pumps. .
But when Qin Lan entered Chen Xin's shelter, she had no doubts about it. Although Chen Xin's shelter was only a private shelter and the place was not big, at a glance, it was still two to three hundred square meters. Yes, the heat provided by a ground source heat pump equipment in such a large area can keep the temperature at around 20°C, and the effect is already very good.
"Use two units? Do you mean to connect the equipment in parallel to improve the heating effect of a single unit?" As soon as Qin Lan said this, Chen Xin understood what she meant, nodded and said: "Of course it can be done, two units of equipment can be used together. One can indeed improve the heating effect. Do you need a high-power ground source heat pump?”
To this question, Qin Lan of course gave an affirmative answer: "The area where the SWAT team is located is not small. Even if we only heat the main area, we need high-power equipment to meet the heating needs. And if we have high-power equipment, we can use pipes Distribute heat to more rooms, ensuring heating for more people.”
"That means you want to use ground source heat pump equipment to build a heating system?" Chen Xin understood Qin Lan's meaning as soon as he heard it.
For places like official shelters with large-area heating needs, the centralized use of multiple devices and the concentrated heat energy provided by the devices distributed to more areas through pipes is indeed better than the heating effect achieved by using separate devices separately. 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.
"A Xin, can you do it?" Qin Lan asked with concern when she saw that Chen Xin understood what she meant.
Of course what she was asking about was 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 while, and after briefly simulating the entire system in his mind, he said: "Of course it can be done, but it requires more materials and parts. High-power equipment does not mean just putting a bunch of low-power equipment together. Yes, it's best to have matching parts.
And if you want to build such a large-scale heating system, not only ground source heat pump equipment is enough. Pipes, heat sinks, pressure pumps... there are many things required. I have never done it before, and you may need professional help. "
Qin Lan was not surprised at all by this. After all, although Chen Xin had worked in mechanical equipment in the past, his hands-on ability was indeed very good. He could DIY ground-source heat pump equipment by himself, which was quite impressive, but he was not a professional after all. Asking him to create a heating system with his bare hands was really asking too much of him.
If it weren't for the fact that a novelist's knowledge reserve is like a bottomless pit and he needs to know a little bit of everything, I'm afraid Chen Xin wouldn't even be able to tell what is needed to make a heating system.
"As for professionals, you don't have to worry, Ah Xin. This city has done project planning for ground source heat pumps for central heating before. With experts in this field, you only need to be responsible for providing equipment." Qin Lan reassured Chen Xin. , this was also the research done when the political commissar and Uncle Ding decided to heat the shelter area where the SWAT team was located.
Without professional theoretical support, they really would not dare to carry out large-scale renovation of the shelter.
Uncle Ding and the political commissar also decided to use ground source heat pump equipment to provide central heating to the area where the SWAT team was located after consulting relevant experts for theoretical verification.
"Since I have expert guidance, I won't have to worry about anything. Just give me your requirements for how much power equipment you need." Chen Xin heard Qin Lan say that experts provided technical support, but he didn't say anything more. He just nodded and agreed to the matter. (End of chapter)
