Chapter 101: Upgrade generator

　　 Shallow geothermal energy is different from deep geothermal energy. Although both belong to geothermal energy, the use of shallow geothermal energy is much simpler than deep geothermal energy.
　　 The use of deep geothermal energy requires deep drilling, which is difficult to mine and relatively difficult to use effectively.
However, the use of shallow geothermal energy is not that complicated. You only need to bury a pipeline in the shallow surface, and then inject a circulating working fluid into the pipeline, and connect it to a heat pump unit to promote the circulating working fluid to continuously absorb geothermal energy and release heat. , You can effectively use the shallow geothermal energy.
　　 The principle is actually the same as that of air conditioners and refrigerators. They all use circulating working fluid to evaporate and absorb heat, and then compress and condense to release heat.
　　 is only different from air conditioners and refrigerators in that the ground source heat pump that uses shallow ground temperature 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 in the current environment, cooling is completely useless.
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 electrical energy required by the compressor to work, and it does not need to consume additional electrical energy for heating. .
　　 After all, whether it is boiler burning 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 the ground source heat pump technology is different. Its heat comes from the stratum itself. The ground source heat pump unit is only used to compress and condense the circulating working fluid and release heat, without additional energy consumption.
　　 So, relatively speaking, ground source heat pumps do save a lot of energy.
　　 Looking at the introduction on the materials and the related principle explanation, Chen Xin moved the idea of ​​putting such a system on his refuge.
　　 On the whole, it is not complicated to make such a set of things. All he needs are pipes, compressors, condensers, evaporators and expansion valves, and these things can be removed by removing an air conditioner.
The installation is not troublesome. Since a simple rack can be used as an algae oxygen generator by default, bury the pipe in the soil of the planting greenhouse, and then install other equipment to let it dissipate heat to the planting greenhouse. Can it be regarded as a ground source heat pump system by default?
Although this increased Chen Xin’s electrical energy consumption and made his already overwhelmed power system even worse, Chen Xin could only accept this fact as the consumption necessary for heating, and chose to upgrade the generator. At the same time as fuel consumption, the total power generation is increased.
　　 "Simple fossil fuel internal combustion generator"
　　"Upgrade plan 1: Improve generator work efficiency, fuel efficiency +5%, improve motor material, power generation +5%, energy consumption -5%, upgrade required survival point 1700"
　　 "Upgrade plan 2: Increase generator output power, fuel consumption +75%, power generation +90%, energy consumption -5%, upgrade requires 2000 survival points"
　　 This is already an upgrade that consumes very high 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 materials needed are various metal materials. When Chen Xin provided a large amount of steel as a substitute, he still consumes one-tenth of the survival point. Upgrading.
　　 After the upgrade, the generators have become bigger, and the two have become one. In addition to the increase in fuel consumption, the power generation is naturally greatly increased.
　　 But overall, 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 overall consumption is still reduced.
　　 And after the upgrade, the power generation efficiency has improved, and the total power consumption has not changed, which is equivalent to a change in direction to reduce fuel consumption.
　　 In terms of Chen Xin's current fuel consumption, his inventory and the gasoline that he can exchange from the SWAT team every month can be maintained to meet his own consumption.
　　 Of course, this does not include the upcoming increase in heating consumption.
　　 Chen Xin is also embarrassed 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 boilers, it’s not impossible. Boiler water heating is an ancient and mature technology, which is relatively safe and 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 restriction on Chen Xin's use of this heating method is the acquisition of fuel.
　　 Want to adopt this method to keep warm, Chen Xin may have to add coal to the monthly transaction with the SWAT team.
　　 Exchange for coal is not a problem for Chen Xin. Coal is not gasoline after all, and Yanguo’s coal production is quite high.
Only in this way, the painting style of Chen Xin Sanctuary will inevitably approach the steampunk style~EbookFREE.me~ Although he personally likes steampunk art, it does not mean that he wants to live. In that environment, because steampunk also means soot pollution.
　　Of course, no one will investigate whether your PM2.5 exceeds the standard in this apocalyptic environment. 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 briquette stove in his hometown. This kind of thing is still widely used in the rural areas of Yan country.
　　 If briquettes are used for heating, Chen Xin thinks this should be an acceptable and effective choice.
In addition, the previously seen ground source heat pump system that uses shallow ground temperature for heating is actually a very good heating method. Even this system will not increase additional energy consumption, which is problematic for current energy acquisition For Chen Xin, it is simply a suitable way of heating.
　　Ground source heat pump technology has actually been used in Bluestar for a long time. It was first proposed in 1912, but at that time energy access was relatively cheap, and at that time it was limited by technology and did not have large-scale applications.
However, after entering the new century, human energy issues have become increasingly tense. Clean, efficient, and recyclable new energy sources have gradually become the focus of attention. The development and utilization of shallow geothermal energy by ground source heat pump technology will naturally Obtained considerable development and promotion and application.
　　In the Qinghai-Tibet Plateau region of Yan Country, this technology has been applied to heating the local people, but the technology is not very mature. Although it has some applications, it is still limited to simple heating.
　　 But the advantage of this technology is that its heating efficiency is quite high.
