Doomsday Bunker Upgrade Chapter 102: Ground source heat pump technology

　　According to the law of conservation of energy, using 1kW·h of electricity to generate heat can never exceed 1KW·h. However, if ground source heat pump technology is used, 1KW·h of electricity can be used to generate 4KW·h. The heat or cold of h.

　　 At first glance, this seems very magical, a bit of a folksy silly feeling, but in fact this is a real technology, and things that can achieve this kind of efficiency abound in our lives, the most of them The most representative is the air conditioner.

In thermodynamics, the ratio of energy conversion efficiency is called the energy efficiency ratio COP.

Among them, the electric heater, that is, the direct electric heating heating, has the lowest energy efficiency ratio, which is only about 60%, which means that it consumes 1KW·h of electricity and can generate 0.6KW·h of heat.

In addition to electric heating, energy boilers have different energy efficiency ratios according to different fuels. Among them, the energy efficiency ratio of natural gas and oil-fired boilers can reach 0.9, while that of coal-fired boilers is only 0.6.

On the contrary, the energy efficiency ratio of electric heating boilers is quite high, which can reach 0.95, which is the so-called direct use of electric ovens.

　　 can reach an energy efficiency ratio of 0.9, which is already very efficient. After all, the law of conservation of energy is stuck here, and it will not reach 1 anyway.

However, when the air conditioner is cooling, the energy efficiency ratio can reach more than 3.

　　 This does not violate the law of conservation of energy, because the air conditioner uses a refrigerant to transport the indoor heat to the outdoors, and the heat it drives is not generated by it, but exists in itself. The air conditioner just transports it.

In fact, in Yan Kingdom, air conditioners with an energy efficiency ratio lower than 2.6~2.8 are not allowed to be sold on the market, and only those with an energy efficiency ratio above 3.2 can be called air conditioners in the true sense.

And understanding this, it is not surprising that the ground source heat pump can achieve an energy efficiency ratio of 4.

As for the reason why air conditioners and ground source heat pumps can achieve such a high energy efficiency ratio, it is because they have a series of equipment including compressors, evaporators, condensers, and expansion valves. The equipment is much more complicated.

However, because of the complex equipment, it also brought considerable energy.

Using 1KW·h electricity to bring 4KW·h heat, this is obviously input>output.

　　 Looking at this data, Chen Xin couldn't help but think of an idea. He found a piece of paper and a pencil, and planned to think about it.

　　 "Using 1KW·h of electricity to bring 4KW·h of heat, even if only half of the heat is used for heating, it is more profitable than directly using electric heaters or electric boilers..." Chen Xin casually scribbled on the paper , He didn’t want to paint anything, it was just a tool for thinking: “If half of the heat is used for heating, the remaining half of the heat is recovered and used for power generation..."

It doesn't matter what you draw on the paper, what matters is what Chen Xin was thinking about at this time. As he thought about it, a flash of inspiration appeared in his mind!

"Even if the efficiency is low, as long as it has an energy efficiency ratio of 0.6, the system can still run on its own!" Chen Xin slapped the table hard, and the whole person became excited.

This is not a nonsense perpetual motion machine, but a waste heat recovery power generation that is very common in the industry. Of course, the waste heat recovered by Chen Xin is a bit large, enough to make this equipment self-sustaining.

　　 It’s not difficult to achieve this, because after the refrigerant brings heat from the stratum, it needs to evaporate and dissipate heat to release a large amount of heat. In this process, whether Chenxin is preparing to boil water or generate electricity by temperature difference, Both can generate enough electricity to keep the whole system running, and there is enough heat for heating.

　　 As for the need to drill holes into the ground to realize this system, Chen Xin lives in an underground shelter. Above him is a layer of soil more than two hundred meters thick, which can be about two hundred meters underground.

This can be seen from the fact that the outside temperature of Chen Xin's shelter is -34°C, and the temperature is still 7°C. If the ventilation system is not constantly ventilating, causing certain The heat energy is lost, and the temperature of the refuge can actually be higher.

Therefore, if Chen Xin wants to use the ground temperature, he does not need to be too troublesome. He only needs to bury the pipes in the ground, or even directly into the soil of his greenhouse.

Although doing so is likely to cause the soil temperature in the greenhouse to decrease and affect the growth of crops.

But Chen Xin can just build this system in the soil layer of the greenhouse, and then use the system upgrade to re-plan and bury the pipeline in a deeper layer.

In fact, Chen Xin's entire shelter is surrounded by thick reinforced concrete and thermal insulation layers. If Chen Xin wants to bury the pipeline in the real stratum, he must penetrate at least 40 cm thick Of reinforced concrete.

Without the help of the system, Chen Xin would simply give up the idea.

After having the system, all Chen Xin needs to do is to use the system to upgrade~IndoMTL.com~ Up to now, Chen Xin has completely understood the horror of this system, although there is only a simple upgrade function, there is no There are so many kinds of tricks and exchanges in other systems, but it's such a simple function, if you use it well, you can simply play with it.

　　The system really cannot change things out of thin air. Basic items must be used as the foundation, but in fact, the upgrade of the system is still very scary.

Chen Xin writes novels, and novelists are all monsters with black holes above their necks. In addition, he likes to think, so Chen Xin also tried to analyze the principle of system upgrade.

　　 However, he came to the conclusion that the system upgrade was far from storing high technology as he had imagined, and then upgrading and unlocking step by step by himself.

　　 is a more terrifying concept upgrade.

　　 To give the simplest example, if the system is a technology upgrade, then if Chen Xin has a tree stick, then he can choose to process this tree stick into a spear, stick, sword or bow and arrow, and upgrade it later In, new materials are added to replace them, and the transformation is more advanced.

　　 All these should be traceable and rules to be followed. After all, the development of every kind of technology must have its predecessor technology.

However, although the upgrade of the system seems to be the same, it is actually much more terrifying, because according to the function of blurring the concept of information state attached to the system, Chen Xin analyzed that the so-called upgrade of the system is in the meaning of concept and information. Admiral an object becomes stronger.

Since this advanced civilization can modify the information contained in an item and make people think it is reasonable, it can also modify the information contained in the item to make it more conceptual. The choice is the process of giving the concept.
