Chapter 122 Large Equipment (710)

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

"Is it alright to soak it like this? Ah Xin, don't you add detergent?" Qin Lan looked at Chen Xin soaking all the parts in water, and confirmed it to him again with concern.

Chen Xin nodded and answered affirmatively: "It's fine to soak in this way, but unfortunately there is no kerosene, otherwise, using kerosene is the 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.

Being stared at by Qin Lan like this, Chen Xin felt a little embarrassed. He pressed his face with his fingers and said, "Will you beat me if I say continue playing games?"

"..." Qin Lan looked at Chen Xin silently, then said after a while: "No, Ah Xin, you can do whatever you want. But I still think you should find something to do, playing games won't make you feel good. Be happy."

Qin Lan's words made Chen Xin smile, but he didn't say much, just nodded and said, "In that case, Alan, go ahead and help me assemble the ground source heat pump. Uncle Ding asked you to send so many. The outdoor unit of the air conditioner is also to replace the ground source heat pump from me, right? How many do you need?"

"Ah Xin, how much material do you need to use to make a ground source heat pump? How big is the heating range?" Qin Lan didn't say his needs first, but just asked Chen Xin about the relevant data of the ground source heat pump.

"A ground source heat pump can be made with the materials removed from an air conditioner outside the unit. 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 about it." Although there are system, but this system does not have any data panel, so Chen Xin does not have much understanding of 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 according to this value, you The heating effect of a ground source heat pump should be roughly estimated, and if it is used in a confined space, the effect should be good.”

Through Chen Xin's explanation, Qin Lan has a general understanding of the performance of the ground source heat pump made by Chen Xin, and he has a certain idea in his heart, so he said to Chen Xin: "I brought eight external air conditioners this time. If If possible, I hope you can make at least six pieces of equipment, and if the other piece of equipment is made with two air conditioners, will it be able to improve the heating effect?"

Before coming, the political commissar deliberately raised this issue with Qin Lan, but the SWAT team did not want to exchange eight materials for eight equipment.

Eight air-conditioning units were replaced by six units, and the other two air-conditioning units were Chen Xin's labor costs. This was the result of discussions between Uncle Ding 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 specific heating effect of the ground source heat pump 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 just a private refuge and the place was not big, at first glance, there were still two or three hundred square meters. Yes, 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 very good.

"Using two? Are you talking about paralleling the devices to improve the heating effect of a single device?" As soon as Qin Lan said it, Chen Xin understood what she meant, nodded and said, "Of course it can be done, the two devices can be connected together. One can really improve the heating effect, do you need a high-power ground source heat pump?"

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

"In other words, do you want to use ground source heat pump equipment to make a heating system?" Chen Xin understood what Qin Lan meant as soon as he heard it.

For places such as official shelters that have large-area heating needs, the centralized use of multiple devices, and the heat energy provided by the devices are concentrated and distributed to more areas through pipes, which is indeed better than the heating effect achieved by using separate devices separately. it 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.

"A Xin, can you do it?" Qin Lan asked with concern when he saw that Chen Xin understood what he meant.

Of course, what she asked 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 simply 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 that a bunch of low-power devices are put together. Yes, it is best to have matching parts.

And if you want to do this kind of large-scale heating system, not only ground source heat pump equipment is enough, pipes, heat sinks, pressurized pumps... I need a lot of things, I have not done it before, and I may need professional help. "

In this regard, Qin Lan is not surprised at all. After all, although Chen Xin has worked in mechanical equipment in the past, his hands-on ability is indeed very good. He can DIY the ground source heat pump equipment by himself. It is quite powerful, but he is not a professional after all. To let him build the heating system by himself is really too much for him.

If it weren't for the novelist's knowledge reserve, which was like a bottomless pit, and he had to understand a little bit of everything, I'm afraid Chen Xin wouldn't even be able to tell what he needed to make a heating system.

"If you are a professional, Ah Xin, you don't have to worry about it. The city has previously planned a ground source heat pump for central heating. With an expert in this area, you only need to be responsible for providing the equipment." Qin Lan calmed Chen Xin's heart. , This is also the research conducted by the political commissar and Uncle Ding when they decided to conduct 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.

Uncle Ding and the political commissar also decided to use ground source heat pump equipment to centrally heat the area where the SWAT team is located after finding relevant experts for theoretical verification.

"Since there are experts to guide me, then I don't have much to do. I need more power equipment, just report the requirements to me." Chen Xin heard Qin Lan say that experts provide technical support, but he didn't say much. Just nodded and agreed.
