Chapter 121: Large equipment (July/Ten)

"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? 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 is the best way to use it."
"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 to be watched by Qin Lan, and after clasping his face with his fingers, he said, "Will you beat me if I say to continue playing games?"
"..." Qin Lan looked at Chen Xin silently, and then said after a while: "No, you can do whatever you want, Axin. But I still think you should find something to do. Playing games does not make you feel good. Have fun."
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 so many. The external air conditioner is also to replace the ground source heat pump 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 the tools to measure it. That’s probably it.
System, but this system doesn’t have any data panel, so Chen Xin doesn’t know much about the equipment he made:
The thermal efficiency of the ground source heat pump is about twice that of the air conditioner under the same power. It should be able to roughly get the heating effect of a ground source heat pump, and if it is 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 made by Chen Xin, and knew in her heart, so she said to Chen Xin:
I’m bringing eight external air conditioners this time. If possible, I hope you can make at least six pieces of equipment from Axin. If another piece of equipment is made with two external air conditioners, will it improve the heating effect?"
Before coming 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.
Eight external air conditioners were replaced with six equipment, 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 certain doubts about the heating effect of ground source heat pumps. Before Qin Lan came here, the political commissar also specifically confessed that she asked Chen Xin for more information about the performance of ground source heat pumps, so as to understand the specific heating effect of ground source heat pumps as much as possible. .
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 area was not large, at a glance, there was still two to three hundred square meters. Yes, the heat provided by such a large area of ​​ground source heat pump equipment can keep the temperature around 20°C, and the effect is already very good.
"Using two? Are you talking about connecting devices in parallel to improve the heating effect of a single device?" As soon as Qin Lan said, Chen Xin understood what she meant, nodded and said, "Of course it can be done. Building 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 can use pipelines. Distribute the heat to more rooms, so that more people can be heated."
"That is to say, 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 with large heating requirements such as official refuges, the use of multiple devices collectively, and the heat energy provided by the devices is concentrated and distributed to more areas through pipes, which is indeed better than the heating effect obtained by using separate devices. it is good.
When multiple devices work together, they can get more heat, 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 while, and after a simple simulation of the entire system in his mind, he said: "Of course it can be done~EbookFREE.me~ but it requires more materials and parts. High-power equipment does not mean that a bunch of low-power It’s ok to put the equipment together, 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... I have a lot of things that I haven't gotten, and maybe I need professional help. "
Qin Lan is not surprised at all. After all, although Chen Xin has done mechanical equipment work, his hands-on skills are really good. He can DIY the ground-source heat pump equipment by himself is already quite good, but he is not a professional after all. Asking him to build the heating system with his bare hands is too demanding of 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 Chen Xin's heart. This was also the research done by the political commissar and Uncle Ding 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 carry out large-scale transformation 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 I have expert guidance, then I won't be troublesome. If I need much power equipment, just report the request to me." Chen Xin heard Qin Lan say that there are experts providing technical support, and he didn't say anything. Just nodded and agreed to the matter.
