Chapter 123: Chapter 121: Large Equipment (7/10)

Even though each part needed scrubbing, with Qin Lan’s help, the two of them quickly managed to clean all the parts and left them soaking in water.

"Is it okay to just soak them like this? Xin, aren’t you going to add any detergent?" Qin Lan asked, as she watched Chen Xin soak all the parts in water, confirming with concern.

Chen Xin nodded, affirming, "Soaking them like this is fine. It’s a pity we don’t have kerosene; it would be the most effective."

"What are you doing now?" Qin Lan asked, removing her gloves and putting them aside, looking toward Chen Xin, waiting for his instructions.

Feeling a little embarrassed under Qin Lan’s gaze, Chen Xin scratched his face with his finger and said, "What if I say I want to keep playing games, will you hit me?"

"..." Qin Lan silently looked at Chen Xin, then said after a while, "No, Xin, you can do whatever you like. But I still think you should find something to do; playing games won’t make you happier."

Qin Lan’s words made Chen Xin smile, but he didn’t say much and just nodded, "Since that’s the case, Lan, continue to help me assemble the geothermal heat pump. Uncle Ding sent over so many air conditioner units for you, hoping to exchange for geothermal heat pumps from me, right? How many do you need?"

"Xin, how much material does it take to make one geothermal heat pump? What’s the heating range?" Qin Lan didn’t state her demand immediately but instead asked Chen Xin about the relevant data for the geothermal heat pump.

"Materials from one air conditioner unit are enough to make one geothermal heat pump, with an effective heating range of about one hundred square meters. As for specific data, I don’t have the tools to measure it; that’s roughly it." Although he had a system, it didn’t have any data panels, so Chen Xin wasn’t very familiar with the equipment he made. "The thermal efficiency of a geothermal heat pump is approximately twice that of an air conditioner of the same power. Based on this calculation, you should roughly determine the heating effect of a geothermal heat pump. In an enclosed space, the effect should be quite good."

Through Chen Xin’s explanation, Qin Lan roughly understood the performance of the geothermal heat pump Chen Xin made. Having an idea in mind, she said to Chen Xin, "I brought eight air conditioner units this time. If possible, I hope you can make at least six devices. If one device is made using two air conditioner units, would it enhance the heating effect?"

Before coming, the political commissar specifically mentioned this issue to Qin Lan. The SWAT team didn’t intend to exchange eight units for eight devices.

Exchanging eight air conditioner units for six devices, leaving the other two units as Chen Xin’s labor fee, was the result of discussion between Uncle Ding and the political commissar.

They still had some doubts about the heating effect of geothermal heat pumps, and before Qin Lan came, the political commissar specifically instructed her to ask Chen Xin as many questions as possible to understand the specific heating effect of geothermal heat pumps.

However, after entering Chen Xin’s shelter, she no longer had any doubts. Although Chen Xin’s shelter was just a private one and not large, it still spanned two to three hundred square meters, and the heat provided by one geothermal heat pump could maintain the temperature at around 20℃, which was already quite good.

"Using two? Are you suggesting parallel equipment to enhance the heating effect of a single unit?" Chen Xin understood Qin Lan’s meaning immediately and nodded, "Of course, it’s doable. Parallelizing two devices can indeed improve the heating effect. Do you need high-power geothermal heat pumps?"

To this question, Qin Lan certainly gave an affirmative answer, "The SWAT team area is not small, and even providing heating to the main area requires high-power equipment to meet heating demands. Moreover, with high-power equipment, we can use pipes to distribute heat to more rooms, ensuring more people are kept warm."

"So you want to use geothermal heat pump equipment to create a heating system?" Chen Xin understood Qin Lan’s intention right away.

For official shelters where there is a large area heating demand, centrally using multiple devices to aggregate and distribute thermal energy to more areas through pipes is indeed more effective than each device providing heat independently.

When multiple devices work together, they can generate more heat, thus providing better heating effects than a single device.

"Xin, can you do it?" Seeing that Chen Xin understood her meaning, Qin Lan asked with concern.

What she was asking wasn’t whether Chen Xin could make the larger geothermal heat pump device that he already knew how to make, but whether he could create a heating system based on the geothermal heat pump equipment.

Chen Xin thought for a bit and after simulating the entire system in his mind, he said, "Of course, it can be done, but it would require more materials and parts. High-power devices aren’t simply a matter of connecting low-power devices together; it’s best to have matching components.

Additionally, to construct such a large-scale heating system, more than just geothermal heat pumps are needed. Pipes, radiators, pressure pumps... there are many things needed, and I haven’t attempted it before; perhaps professional help is needed."

Qin Lan wasn’t surprised by this; although Chen Xin had experience in mechanical equipment work and was proficient at DIYing a geothermal heat pump, he wasn’t a professional. To expect him to single-handedly build a heating system might be too demanding.

If it weren’t for the novelist-like endless knowledge base, knowing bits of everything, perhaps Chen Xin wouldn’t even be able to say what is needed to build a heating system.

"There’s no need to worry about professionals, Xin. Previously, the city had a project plan for centralized heating using geothermal heat pumps, and experts in this field are available. You just need to provide the equipment." Qin Lan reassured Chen Xin, which was part of the preliminary research done by the political commissar and Uncle Ding when they decided to implement a heating system in the SWAT team’s shelter area.

Without professional theoretical support, they wouldn’t dare undertake such large-scale renovations in the shelter.

Uncle Ding and the political commissar made the decision to use geothermal heat pump equipment to centralize heating for the SWAT team area after consulting relevant experts for theoretical validation.

"Since there are experts to guide the process, I won’t interfere further. Just report the power requirements to me and I’ll take care of it," Chen Xin replied, nodding after hearing Qin Lan say experts would provide technical support, thereby agreeing to the matter.
