Chapter 102

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 deep geothermal energy.

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

However, the utilization of shallow geothermal energy is not so complicated. It only needs to embed pipes in the shallow surface, inject circulating working fluid into the pipes, connect the heat pump units, and promote the circulating working fluid to continuously realize the process of absorbing geothermal energy and releasing heat energy, so that the shallow geothermal energy can be effectively utilized.

In fact, its principle is the same as that of air conditioner and refrigerator. It uses circulating working medium to absorb heat, then compresses and condenses to release heat.

But different from the public regulation and refrigerator, the ground source heat pump using 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 refrigeration, which is totally 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 electric energy required by the compressor, and does not need to consume additional electric energy to heat.

After all, whether it's boiler burning or electric heating, in essence, it's energy consumption to convert heat. Even air conditioning heating is also electric auxiliary heating, which needs to consume a lot of electric energy.

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

So relatively speaking, the ground source heat pump really needs to save a lot of energy.

Looking at the introduction of the materials and the explanation of the relevant principles, Chen Xin came up with the idea of applying such a system to his refuge.

On the whole, it's not complicated to make such a set of things. All he needs is pipes, compressors, condensers, evaporators and expansion valves, which can be obtained by dismantling an air conditioner.

And the installation is not troublesome. Since a simple shelf can be regarded as an algae oxygen generator by default, it should also be regarded as a ground source heat pump system if the pipe is buried in the soil of the planting greenhouse, and then other equipment is installed to dissipate heat to the planting greenhouse?

Although this still aggravates Chen Xin's power consumption and makes his already overburdened power system worse, as a necessary consumption for heating, Chen Xin can only accept this fact and chooses to upgrade the generator to increase the total power generation while increasing the fuel consumption.

"Simple fossil fuel internal combustion generator"

"upgrade scheme 1: improve the working efficiency of the generator, fuel efficiency + 5%, improve the motor material, power generation + 5%, energy consumption - 5%, upgrade survival 1700"

"upgrade scheme 2: improve the output power of the generator, fuel consumption + 75%, power generation + 90%, energy consumption - 5%, upgrade survival 2" 000 "

this is already a very high survival consumption upgrade. In addition to the overall upgrade of a room, Chen Xin upgraded a single device with more than 1000 points for the first time.

Fortunately, in addition to Chen Xin's spare generator, the required materials are all kinds of metal materials. Chen Xin provided a large number of steel as a substitute, but he still completed the upgrade with one tenth of the survival cost.

After upgrading, the generators become bigger, and two of them become one. In addition to the increase of fuel consumption, the power generation is also greatly improved.

However, in general, the energy consumption has been reduced, because Chen Xin can now use 1.75 times of the original fuel to obtain 1.9 times of the electric energy. In general, the consumption has been reduced.

Moreover, after the upgrade, the power generation efficiency is improved, and the total power consumption remains unchanged, which means that the fuel consumption is reduced by changing the direction.

Taking Chen Xin's current fuel consumption as an example, his inventory and the gasoline he can exchange from the special police force every month can meet his own consumption.

Of course, this does not include the upcoming increase in heating consumption.

For heating, Chen Xin is also in a dilemma. Electric heating is the most efficient way, but it is the most simple and fast way. Chen Xin only needs to plug in his electric heater.

As for the boiler is not bad, boiler water heating this is an old and mature technology, relatively more safe and stable, the carbon dioxide produced by combustion can also be supplied to the oxygen generator for oxygen recovery, can be said to be a very good choice.

The only restriction for Chen Xin to adopt this heating method is the acquisition of fuel.

To get warm in this way, Chen Xin may have to add coal to his monthly deal with the Swat.

In exchange for coal is not a problem for Chen Xin. After all, coal is not gasoline, and Yanguo's coal production is also quite high.

Only in this way, the painting style of Chen Xin's refuge will inevitably be close to the style of Steampunk.

Although he personally likes the art of Steampunk style, it doesn't mean he wants to live in such an environment, because Steampunk also means soot pollution.Of course, no one is going to investigate whether your PM2.5 exceeds the standard in this last world environment. The PM2.5 of the whole atmosphere has already exploded.

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

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

If it is to use honeycomb briquette for heating, Chen Xin thinks it should be an acceptable and effective choice.

In addition, the ground source heat pump system with shallow geothermal energy is also a very good heating method, and even this system will not increase additional energy consumption. For Chen Xin, who has problems in energy acquisition, it is simply the most suitable heating method.

In fact, the ground source heat pump technology has been used in Bluestar for a long time. It was first proposed in 1912, but at that time, the energy was relatively cheap. In addition, limited by science and technology at that time, there was no large-scale application.

But after entering the new century, the energy problem of mankind is 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 has naturally been greatly developed and widely applied.

In Yanguo's Qinghai Tibet Plateau, 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 its heating efficiency is quite high.
