Chapter 122

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

"Is it OK to just soak like this? Xin, don't you add detergent? " Qin LAN looked at Chen Xin so all the parts with water bubble, concern to him again confirmed.

Chen Xin nodded his head and answered in a positive way: "it's a pity that there is no kerosene, otherwise kerosene is the best."

"What are you doing now?" Taking off the gloves and putting them aside, Qin LAN looks at Chen Xin, waiting for him to speak.

Chen Xin felt a little embarrassed when he was watched by Qin LAN. He buttoned his face with his fingers and said, "if I say continue to play games, will you beat me?"

“……” Qin LAN looked at Chen Xin in silence. After a while, she said, "no, Xin, you can do whatever you want. But I still think you should find something to do. Playing games doesn't make you happy

Qin Lan's words made Chen Xin smile, but he didn't say much, just nodded and said: "in this case, ah LAN, please continue to help me to assemble the ground source heat pump. Uncle Ding asked you to send so many air-conditioning external units to replace ground source heat pump from me, right? How many do you need? "

"Ah Xin, how many materials do you need to consume to make a ground source heat pump? How large is the heating range? " Qin LAN did not say his needs first, but asked Chen Xin about the relevant data of ground source heat pump.

"A ground source heat pump can be made from the material removed from an air conditioner, and 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 is a system, there is no data panel in this system, so Chen Xin doesn't know much about the equipment he made: "the thermal efficiency of ground source heat pump is about twice that of air conditioning under the same power. According to this value, you should be able to roughly get the heating effect of a ground source heat pump. If you use it 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 has a number in her mind, so she said to Chen Xin, "I've brought eight external air conditioners this time. If I can, I hope you can make at least six equipment. If the other equipment is made with two external air conditioners, can it improve the heating efficiency "Fruit?"

Before coming here, the political commissar specially mentioned this issue with Qin LAN. The special police team didn't want to say eight materials for eight equipment.

Eight external air conditioners were replaced by six equipment, and the other two external air conditioners were Chen Xin's labor costs. This was the result of discussion 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 specially told her to ask more information about the performance of the ground source heat pump from Chen Xin, so as to understand the specific heating effect of the ground source heat pump as much as possible.

However, when Qin LAN entered Chen Xin's refuge, she had no doubt about it. Although Chen Xin's refuge is only a private one, and the place is not big, at a glance, there are still two or three hundred square meters. The heat provided by such a large area of ground source heat pump equipment can keep the temperature around 20 ℃, and the effect is very good.

"Two? Do you mean parallel equipment can improve the heating effect of single equipment? " As soon as Qin Lan said, Chen Xin understood her meaning, nodded and said, "of course, it can be done. The combination of two devices 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 it is only for the main district heating, it also needs high-power equipment to meet the heating demand. And with high-power equipment, we can use pipes to disperse the heat to more rooms, so that more people can get heating protection. "

"In other words, you want to use ground source heat pump equipment to make a heating system?" Chen Xin understood what Qin LAN meant.

For the official shelter, where there is a large area heating demand, the heating effect of centralized use of multiple equipment and the heat energy provided by the equipment is better than that of separate use of separate equipment.

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

"Xin, can you do it?" Qin LAN see Chen Xin understand their own meaning, so concerned asked.

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

Chen Xin thought about it for a moment, and after simply simulating the whole system in his mind, he said: "of course, it can be done, but it needs more materials and parts. High power equipment does not mean that a bunch of low-power equipment can be put together. It's better to have matching parts.

And if we want to do this kind of large-scale heating system, ground source heat pump equipment is not only enough, pipes, radiator, booster pump There are a lot of things I want. I haven't made them. Maybe I need the help of professionals. "Qin Lan was not surprised by this. After all, although Chen Xin had worked in mechanical equipment in those years, his hands-on ability was really good. He could DIY the ground source heat pump equipment by himself, but he was not a professional after all. It was too high for him to make the heating system by himself.

If it wasn't for the novelist's knowledge reserve, which is like a bottomless hole, and he needs to know a little bit about everything, I'm afraid Chen Xinlian can't even say what it takes to make a heating system.

"Professionals, ah Xin, you don't have to worry about it. The city has done the project planning of ground source heat pump for central heating before. With experts in this field, you only need to be responsible for providing equipment." Qin LAN calms Chen Xin's heart, which is also the research done by the political commissar and uncle Ding when they decided to do heating in the shelter area where the SWAT team is located.

Without the support of professional theory, they dare not carry out large-scale reconstruction of the refuge.

Ding Shuhe and political commissar also decided to use ground source heat pump equipment for central heating in the area where the special police team is located after they found relevant experts to verify the theory.

"Since there are experts to guide me, I don't have much to do. Just report me the requirements for the high-power equipment I need." Chen Xin heard Qin LAN say that there are experts to provide technical support, he did not say anything more, just nodded and agreed to this matter.
