Shallow geothermal energy is different from deep geothermal energy, although both are geothermal energy, but the utilization of shallow geothermal energy is much simpler than deep geothermal energy.

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

However, the utilization of shallow geothermal energy is not so complicated, only need to bury the pipeline in the shallow surface, and then inject the circulating working fluid into the pipeline, connect the heat pump unit, and promote the circulating working fluid to continuously realize the process of absorbing geothermal heat and releasing heat energy, which can effectively utilize the shallow geothermal energy.

In fact, its principle is the same as that of air conditioners and refrigerators, which is to use circulating working fluid to evaporate and absorb heat, and then compress and condense to release heat.

It's just that unlike the public adjustment and refrigerator, the ground source heat pump that uses shallow geothermal energy absorbs heat from the ground and releases heat indoors.

In fact, this system can be used not only for heating, but also for cooling, but it is not needed at all 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 the same electricity, it only needs to supply the electrical energy required for the compressor to work, and does not need to consume additional electrical energy to heat.

After all, whether it is a boiler or electric heating, it is essentially consuming energy to convert heat, and even air conditioning heating is also an electric auxiliary heat, which needs to consume a lot of electricity.

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

Therefore, relatively speaking, ground source heat pumps do have a lot of energy saving.

Looking at the introduction on the materials and the relevant principle explanations, Chen Xin moved the idea of such a system for his shelter.

On the whole, it is not complicated to make such a set of things, all he needs is the pipes, compressors, condensers, evaporators and expansion valves, and these things are dismantled and an air conditioner is available.

And the installation is not troublesome, since building a simple shelf can be defaulted to an algae oxygen generator, then bury the pipe into the soil of the planting greenhouse, and then install other equipment, let it dissipate heat against the planting greenhouse, it should also be a set of ground source heat pump system by default, right?

Although this still aggravated Chen Xin's power consumption, making his already overwhelmed power system even worse, Chen Xin could only accept this fact as a necessary consumption for heating, and chose to upgrade the generator, increasing fuel consumption while increasing the total amount of power generation.

"Simple Fossil Fuel Internal Combustion Generator"

"Upgrade plan 1: improve the efficiency of the generator, fuel efficiency +5%, improve the motor material, power generation +5%, energy consumption -5%, upgrade the required survival point 1700"

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

This is already an upgrade with a very high survival point consumption, in addition to upgrading a certain 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 various metal materials, and in the case that Chen Xin provided a large amount of steel as a replacement, he still completed the upgrade with one-tenth of the survival point consumption.

After the upgrade, the generator has become larger, and the two have become one, in addition to the increase in fuel consumption, the power generation has also been greatly increased.

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, and in general, the consumption is still reduced.

Moreover, after the upgrade, the power generation efficiency is improved, and the total power consumption remains unchanged, which is equivalent to reducing the fuel consumption in the change direction.

Based on Chen Xin's current fuel consumption, his inventory and the gasoline that he can exchange for 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 embarrassed about 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 the boiler, it is not impossible, boiler boiling water heating is an ancient and mature technology, relatively safer and more stable, and the carbon dioxide produced by combustion can also be supplied to the oxygen generator for oxygen recovery, which can be said to be a very good choice.

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

If he wants to heat himself in this way, Chen Xin may have to add coal to his monthly deal with the SWAT team.

In exchange for coal, it did not pose a problem for Chen Xin, coal was not gasoline after all, and the coal production in Yanguo was also quite high.

It's just that in this way, Chen Xin's style of painting will inevitably move towards the steampunk style.

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

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

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

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

If honeycomb coal is used for heating, Chen Xin feels that this should be an acceptable and effective choice.

In addition, the ground source heat pump system that I saw before with shallow geothermal energy heating is actually a very good heating method, and even this system will not add additional energy consumption, which is a very suitable heating method for Chen Xin, who currently has problems with energy access.

In fact, ground source heat pump technology has been applied in Bluestar for a long time, and it was first proposed in 1912, but at that time, energy access was relatively cheap, and due to the limitations of science and technology at that time, there was no large-scale application.

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

In the Qinghai-Tibet Plateau region of Yanguo, 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.

However, the advantage of this technology is that it is quite efficient.
