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 extract and makes effective use relatively difficult.
However, the utilization of shallow geothermal energy is not that complicated. You only need to bury pipelines in the shallow ground, inject circulating working fluid into the pipeline, and connect to the heat pump unit to promote the circulating working fluid to continuously absorb geothermal energy and release thermal energy. , you can effectively utilize the shallow ground temperature energy.
Its principle is actually the same as the working principle of air conditioners and refrigerators. They all use circulating working fluid to evaporate and absorb heat, and then compress and condense to release heat.
However, unlike public air conditioners and refrigerators, geothermal heat pumps that use shallow ground temperature energy absorb heat from the ground and release heat indoors.
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 a boiler or electric heating, it essentially consumes energy to convert heat. Even air-conditioning heating uses electric auxiliary heating, which consumes a lot of electricity.
But 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.
So relatively speaking, ground source heat pumps do save a lot of energy.
After looking at the introduction in the information and the related principles, Chen Xin came up with the idea of installing such a system for his shelter.
On the whole, it is not complicated to build such a set of things. All it needs is pipes, compressors, condensers, evaporators and expansion valves, and these things are available by disassembling an air conditioner.
The installation is not troublesome. Since a simple shelf can be used as an algae oxygen generator by default, then it should be possible to bury the pipes in the soil of the greenhouse and install other equipment so that it can dissipate heat toward the greenhouse. Can it be regarded as a ground source heat pump system by default
Although this still increased Chen Xin's electricity consumption and made his already overwhelmed power system even worse, as a necessary consumption for heating, Chen Xin could only accept this fact and chose to upgrade the generator. While reducing fuel consumption, it also increases total power generation.
"Simple Fossil Fuel Internal Combustion Generator"
"Upgrade Plan 1: Improve generator efficiency, fuel utilization efficiency +5%, improve motor material, power generation +5%, energy consumption -5%, upgrade required survival points 1700"
"Upgrade plan two: increase generator output power, fuel consumption +75%, power generation +90%, energy consumption -5%, 2000 survival points required for upgrade"
This is already an upgrade that consumes a very high number of survival points. In addition to upgrading a certain room as a whole, this is the first time that Chen Xin has upgraded a single piece of equipment with more than a thousand points.
Fortunately, in addition to Chen Xin's backup generator, the required materials were all kinds of metal materials. Even though Chen Xin provided a large amount of steel as a substitute, he was able to complete the project with one-tenth of his survival points. Upgraded.
After the upgrade, the generator became larger, and two generators became one. In addition to the increase in fuel consumption, the power generation capacity was naturally greatly increased.
However, overall, the energy consumption has been reduced, because Chen Xin can now obtain 1.9 times the electricity using 1.75 times the original fuel. Overall, the consumption has been reduced.
Moreover, after the upgrade, the power generation efficiency is improved and the total power consumption remains unchanged, which is equivalent to a change in fuel consumption.
Based on Chen Xin's current fuel consumption, his inventory and the gasoline 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 simplest and fastest way. Chen Xin only needs to plug in his electric heater.
As for burning boilers, it is not impossible. Boiling water for heating is an ancient and mature technology. It 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. a choice.
The only thing that restricts Chen Xin from using this heating method is the availability of fuel.
If he wants to use this method of heating, Chen Xin may have to add coal to the monthly transaction with the SWAT team.
Exchanging coal does not pose a problem to Chen Xin. Coal is not gasoline after all, and Yanguo's coal output is also quite high.
But in this way, the painting style of Chen Xin Shelter will inevitably move closer to the steampunk style.
Although he personally likes steampunk-style art, this does not mean that he wants to live in that environment, because steampunk also means soot pollution.
Of course, in today's apocalyptic environment, no one will investigate whether your PM2.5 exceeds the standard. PM2.5 in the entire atmosphere has already exceeded the limit.
So of course it can be done, but how to do it is a big problem.
When Chen Xin was a child, he had seen that kind of briquette stove in his hometown. This kind of thing is still widely used in rural areas of Yan State even now.
If briquettes are used for heating, Chen Xin thinks this should be an acceptable and effective choice.
In addition, the ground source heat pump system that we saw before using shallow ground temperature energy for heating is actually a very good heating method. Even this system does not increase additional energy consumption, which is a good solution to the current energy acquisition problems. For Chen Xin, it is simply the most suitable way to keep warm.
Ground source heat pump technology has actually been used in Blue Star for a long time. It was first proposed in 1912. However, energy acquisition was relatively cheap at that time and due to limited technology at the time, it was not widely used.
However, after entering the new century, human energy problems have become increasingly tense. 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 achieved considerable development and promotion and application.
In the Qinghai-Tibet Plateau region of Yan State, this technology has been used to heat local people, but the technology is not very mature. Although it has been used, it is still limited to simple heating.
But the advantage of this technology is that its heating efficiency is quite high. (End of chapter)
