"I have enough food here, don't worry about it, just me and Xiaoxin, it's enough to eat for another three or five years." Mo Qingyan put on a confident look and was very optimistic: "After three or five years, the country will definitely begin to resume production, and even if you have to live underground, eating will definitely not be a problem." ”

Regarding Mo Qingyan's optimism, Chen Xin saw that her heart was weak, but friends should not force others to accept your kindness, so Chen Xin did not continue to ask, but said to Mo Qingyan: "Since you have said so, Long Niang, then I will not force you, if you need help, please contact me at any time." And you're ......"

Chen Xin hesitated for a moment, but still said to Mo Qingyan: "Although Long Niang, your reserves must be enough for you to eat, but now is the end of the world after all, and no one knows what will happen in the future, I suggest that you still get a planting greenhouse, and have a certain self-sustaining ability, which can make you last longer, and you can also improve your life." ”

For Chen Xin's proposal, Mo Qingyan had considered it before, after all, no matter how much food reserves there are, there will be a day when they will run out, and they must always plan for the reserves after they are eaten.

"Your proposal is very good, but the problem is that I really don't have the conditions to build a planting greenhouse! I told Ah Lan that I wanted to grow mushrooms, but she later found someone to help her, saying that it was not suitable for transformation, so I didn't get it. Of course, Mo Qingyan knew what she should plant, but she really didn't have the conditions to grow mushrooms.

Although Mo Qingyan's shelter has a good thermal insulation layer, and the air conditioner can be turned on, which can ensure that the temperature in the shelter is not too low, but if you want to grow mushrooms, the conditions are indeed lacking.

"Can't you grow mushrooms? This ......" Chen Xin frowned and thought about it, and said to Mo Qingyan: "Since you can't grow mushrooms, Long Niang, you might as well do hydroponic planting like me." ”

Speaking of this, Chen Xin went through the thoughts in his mind, and explained his thoughts to Mo Qingyan with a little excitement: "I will help Long Niang install a set of ground source heat pump equipment, and then connect a set of aquaponics hydroponic planting system and waste heat recovery power generation device on this set of equipment."

This allows you to generate and heat electricity with a ground source heat pump, keeping the system running and producing food for you. ”

"Is this really okay?" When Mo Qingyan heard Chen Xin's description, she couldn't help but feel a little moved.

The system that Chen Xin said is indeed very beautiful, because it can not only generate electricity, but also heat, and can also produce food, it can be said that with such a set of things, Mo Qingyan's shelter does not have to worry about heating and eating.

Facing Mo Qingyan's tempting question, Chen Xin nodded affirmatively: "The ground source heat pump device can achieve an energy efficiency ratio of 4, and recovering part of the energy to generate electricity is enough to drive it to run on its own, and at the same time it has enough heat output."

As for the hydroponic planting of aquaponics, as long as the temperature is guaranteed, this is still very easy to get, and I plan to get a set of such equipment myself, so you can rest assured that Long Niang. ”

"In that case...... Mo Qingyan nodded, as if she was moved by Chen Xin's words: "Let me think about it, after all, it's a big project to get this, and you don't even have a set of equipment for the ingredients now, right?" ”

Regarding Mo Qingyan's question, Chen Xin just smiled and said, "If necessary, the equipment can be ready at any time." ”

"Okay, then let me think about it and get back to you." Mo Qingyan still didn't agree directly.

Chen Xin just nodded at this and didn't say anything more.

——————————————————

Back at his shelter, Chen Xin contacted Qin Lan and asked her for supplies including drill bits and compressors.

"Ah Xin, why do you want these things?" When Qin Lan heard what Chen Xin wanted, he didn't immediately agree, but asked him for it: "We don't have these things in stock in our SWAT team that you want, I'm afraid I have to collect them to get them for you." ”

"I'm going to use these things to assemble a ground source heat pump myself and use it to heat my shelter." For this, Chen Xin did not hide anything from Qin Lan.

Hearing Chen Xin say that he wanted to assemble the ground source heat pump by himself, Qin Lan was a little confused, and only after Chen Xin's patient explanation did he understand what was going on.

"I see, then I'll ask the captain when I go back, except for the drill bit, many of the things you want are not easy to get now." Qin Lan didn't dare to pack the ticket and said that she could help Chen Xin get things.

Although Chen Xin basically has all the things he wants, he can buy them casually before the end of the world, but it is difficult to get them in the last days.

Although the country is restarting its industry, it is obvious that all production capacity is given priority to supply the places where it is most needed, and the first to resume production must be basic industrial facilities, such as Chen Xinyao's compressors and evaporators, and even if they are produced now, they are also large-scale industrial things.

Can it be said that the production of these things must be sent directly to the factories that have resumed production, rather than being sold to individuals.

So if you want to get these things, even the SWAT team can only collect them little by little.

After ending the call with Chen Xin, Qin Lan naturally informed Uncle Ding of the news as soon as possible.

"Commissar, what do you think?" Uncle Ding looked at the political commissar, they happened to be talking about things when Qin Lan came.

For this kind of thing that needs to be decided and judged, Uncle Ding has always been accustomed to asking the political commissar for his opinion first.

"I also know about this kind of ground source heat pump equipment, it seems that before the disaster, during the 13th Five-Year Plan, the city was going to have three heating projects using this technology, but the meteorite fell before it was completed." The political commissar had some understanding of this kind of technology and equipment, thought for a while and replied: "If this Comrade Chen Xin can really transform this kind of thing by himself, I think we can help, and by the way, we can also change a few pieces of equipment." ”

Uncle Ding listened to the political commissar's opinion, and naturally understood what the old guy meant: "Political commissar, are you saying that we also use this?" ”

"A snowstorm cools down by 30 degrees, and the temperature may be even lower in the future, although there is still electricity in the city, and there are boilers in the shelters, but all the coal is transported from outside, what if the railway transportation is interrupted? Always have a backup. The political commissar looked at Uncle Ding and said with burning eyes.

After listening to the political commissar's suggestion, Uncle Ding also nodded and said to Qin Lan: "In that case, Xiao Qin, you tell Lao Li and let him take someone out to collect materials." ”
