Doomsday Bunker Upgrade

Shallow geothermal energy is different from deep geothermal energy. Although both belong to geothermal energy, the utilization of shallow geothermal energy is much simpler than that of deep geothermal energy.

The utilization of deep geothermal energy requires deep drilling, which is difficult to exploit and relatively difficult to utilize effectively.

However, the utilization of shallow geothermal energy is not so complicated. It is only necessary to bury the pipeline in the shallow surface, inject the circulating working medium into the pipeline, and connect the heat pump unit, so that the circulating working medium can continuously realize the process of absorbing geothermal heat and releasing thermal energy. , the shallow geothermal energy can be effectively utilized.

Its principle is actually the same as the working principle of air conditioners and refrigerators. It uses the circulating working fluid to evaporate and absorb heat, and then compress and condense to release heat.

However, unlike air conditioners and refrigerators, the ground source heat pump using shallow geothermal energy absorbs heat from the ground, and releases heat from the interior.

In fact, this system can be used not only for heating, but also for cooling, but cooling is completely useless in the current environment.

Compared with other heating methods, the advantage of ground source heat pump technology is that it consumes less energy. Although it also consumes electricity, it only needs to supply the electricity required for the compressor to work, and does not need to consume additional electricity for heating. .

After all, whether it is burning a boiler or electric heating, it essentially consumes energy to convert heat. Even air conditioning heating uses electric auxiliary heat, which requires a lot of electric energy.

But the ground source heat pump technology is different. Its heat comes from the formation itself. The ground source heat pump unit is only used to compress and condense the circulating working fluid and release heat, and there is no additional energy consumption.

Therefore, relatively speaking, the ground source heat pump does save a lot of energy.

Looking at the introduction in the materials and the related principle explanation, Chen Xin moved to the idea of ​​adding such a system to his shelter.

On the whole, it is not complicated to get such a set of things, all he needs are pipes, compressors, condensers, evaporators and expansion valves, and these things can be removed from an air conditioner.

And the installation is not troublesome. Since a simple shelf can be used as an algae oxygen generator by default, then bury the pipes in the soil of the planting greenhouse, and then install other equipment to let it dissipate heat against the planting greenhouse. Can it be regarded as a ground source heat pump system by default?

Although this still aggravated Chen Xin's power consumption and made his already overwhelmed power system even worse, as the necessary consumption for heating, Chen Xin could only accept this fact, and chose to upgrade the generator. While reducing fuel consumption, the total power generation is increased.

"Simple Fossil Fuel Internal Combustion Generator"

"Upgrade plan 1: Improve the working efficiency of the generator, increase the fuel efficiency by 5%, improve the material of the motor, increase the power generation by 5%, energy consumption by -5%, and upgrade the required survival points by 1700"

"Upgrade plan 2: Increase the output power of the generator, fuel consumption +75%, power generation +90%, energy consumption -5%, 2000 survival points required for the upgrade"

This is already an upgrade with a very high cost of survival points. In addition to upgrading a room as a whole, Chen Xin is the first time to upgrade a single device with more than 1,000 points.

Fortunately, in addition to Chen Xin's backup generator, the required materials are all kinds of metal materials. When Chen Xin provided a large amount of steel as a substitute, he still consumed one tenth of the survival points. upgrade.

The upgraded generators have become larger, and two have become one. In addition to the increase in fuel consumption, the power generation is naturally greatly improved.

However, in general, the energy consumption is still reduced, because Chen Xin can now use 1.75 times the original fuel to obtain 1.9 times the electricity, which reduces the consumption in general.

Moreover, after the upgrade, the power generation efficiency has been improved, and the total power consumption has not changed, which means that the change of direction reduces the fuel consumption.

As far as Chen Xin's current fuel consumption is concerned, his inventory and the gasoline he can exchange from the SWAT team every month can still meet his own consumption.

Of course, this does not take into account the upcoming increase in heating consumption.

Chen Xin is also in a dilemma for heating. Electric heating is the least efficient way, but it is the easiest and fastest way. Chen Xin only needs to plug in his electric heater.

As for burning a boiler, it is not impossible. Boiler heating is an ancient and mature technology, which is relatively safer and more stable. The carbon dioxide produced by combustion can also be supplied to the oxygen generator for oxygen recovery, which can be said to be quite good. an option.

The only thing that restricts Chen Xin from adopting this heating method is the acquisition of fuel.

To keep warm in this way, Chen Xin may have to add coal to his monthly deal with the SWAT team.

Exchange for coal is not a problem for Chen Xin. After all, coal is not gasoline, and the coal output of Yan Kingdom is quite high.

Only in this way, the painting style of Chen Xin Refuge will inevitably approach the style of steampunk.

Although he personally likes steampunk-style art, it doesn't mean he wants to live in that environment, because steampunk also means soot pollution.

Of course, in this apocalyptic environment, no one will investigate whether your PM2.5 exceeds the standard, and the PM2.5 in the entire atmosphere has already exploded.

So of course it can be done, but how to do it is a big problem.

When Chen Xin was a child, he still saw that kind of honeycomb stove in his hometown, and this kind of thing is still widely used in the rural areas of Yan Kingdom.

If it is to use honeycomb for heating, Chen Xin feels that this should be an acceptable and effective choice.

In addition, the ground source heat pump system that uses shallow ground temperature for heating as seen before is actually a very good heating method, and even this system will not increase additional energy consumption, which is problematic for the current energy acquisition. As far as Chen Xin is concerned, it is simply the most suitable way of heating.

In fact, the ground source heat pump technology has been applied in Bluestar for a long time. It was first proposed in 1912, but the energy acquisition was relatively cheap at that time, and due to the limitation of technology at that time, it was not applied on a large scale.

However, after entering the new century, the energy problem of human beings has become increasingly tense, and clean, efficient and recyclable new energy has gradually become the focus of people's attention. The development and utilization of shallow geothermal energy by ground source heat pump technology will naturally It has been greatly developed and popularized.

In the Qinghai-Tibet Plateau region of the Yan Kingdom, this technology has been applied to the heating of local people, but the technology is not very mature. Although it has been applied, it is still limited to simple heating.

The advantage of this technology, however, is that its heating efficiency is quite high.
