According to the law of conservation of energy, it is impossible to generate more than 1 kW·h of electricity with 1 kW·h of electricity, but if ground source heat pump technology is used, it can bring 4 KW·h of heat or cooling with 1 kW·h of electricity.

At first glance, this seems to be magical, a bit of a folk science fool, but in fact this is a real technology, and things that can achieve this efficiency abound in our lives, the most representative of which 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, direct electric heating, has the lowest energy efficiency ratio, only about 60%, that is, it consumes 1KW·h of electric energy, which can produce 0.6KW·h of heat.

In addition to electric heating, the energy efficiency ratio of energy boilers is also different according to different fuels, among which the energy efficiency ratio of natural gas and oil-fired boilers can reach 0.9, and that of coal is only 0.6.

On the contrary, the energy efficiency ratio of electric boilers is quite high, which can reach 0.95, which is the so-called direct electric oven, which is better than boiling water quickly with heat.

Being able to achieve an energy efficiency ratio of 0.9 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 carry the heat from the interior to the outside, and the heat driven by it is not generated by it, but exists itself, and the air conditioner just carries it.

In fact, in Yanguo, air conditioners with an energy efficiency ratio of less than 2.6~2.8 are not allowed to be sold at all, and only those that reach more than 3.2 can be called air conditioners in the real sense.

With this in mind, it is not uncommon for ground source heat pumps to achieve an energy efficiency ratio of 4.

As for why air conditioners and ground source heat pumps can achieve such an energy efficiency ratio, it is because they have a series of equipment including compressors, evaporators, condensers, and expansion valves, which are much more complex than equipment such as boilers.

However, because of a complete set of complex equipment, it also brings considerable energy.

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

Looking at this data, Chen Xin couldn't help but have an idea in his mind, he took out 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 ...... than directly using an electric heater or electric boiler" Chen Xin scribbled on the paper, he didn't want to draw anything, this is just a tool to assist in thinking: "If half of the heat is used for heating, the remaining half of the heat is recovered and used to generate electricity......

It doesn't matter what you draw on the paper, what matters is what Chen Xin is thinking about at this time, and as he thinks, a glimmer of inspiration also emerges in his mind!

"No matter how low the efficiency is, as long as it can have an energy efficiency ratio of 0.6, the system can continue to operate sustainably!" Chen Xin slapped the table hard, and the whole person became excited.

This is not a nonsense perpetual motion machine, but it is a very common waste heat recovery power generation in industry, of course, Chen Xin recovers a little more waste heat, enough to make this set of equipment self-sustaining.

This is not difficult to achieve, because after the refrigerant brings the heat out of the formation, it needs to evaporate and heat dissipate to release a large amount of heat, and in the process, whether Chen Xin is preparing to boil water or generate electricity with a temperature difference, it can generate enough electricity to keep the whole system running, and there is enough heat energy to heat it.

As for the need to drill holes in the ground to realize this system, Chen Xin lives in an underground shelter, and above his head is a layer of soil more than 200 meters thick, which can be about 200 meters underground.

This can be seen from the fact that the outside temperature of the Chen Xin shelter is -34 °C, and there is still a temperature of 7 °C, if it is not for the ventilation system to continuously ventilate, resulting in a certain amount of heat energy loss, the temperature of the shelter can actually be a little 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 pipe in the ground, or even directly into the soil of his planting greenhouse.

Although this is likely to cause the soil temperature of the planting greenhouse to decrease, affecting the growth of crops.

But Chen Xin could have simply built the system in the soil layer of the greenhouse, and then used the system upgrade to re-plan and bury the pipes deeper into the ground.

In fact, Chen Xin's entire shelter is wrapped in thick reinforced concrete and thermal insulation, and if Chen Xin wants to bury the pipe in the real ground, he has to penetrate at least 40 centimeters of reinforced concrete.

Without the help of the system, Chen Xin would have simply given up on this idea.

After having the system, all Chen Xin needs to do is upgrade with the system.

Up to now, Chen Xin has thoroughly understood the horror of this system, although there is only one simple upgrade function, and there are not as many kinds of tricks and exchanges as other systems, but it is such a simple function, if it is used well, it can be played.

It's true that the system can't conjure things out of thin air, and it must have basic items as a foundation, but in fact, the upgrade of the system is still very scary.

Chen Xin writes novels, and novelists are monsters with black holes above the neck, and he likes to think, so Chen Xin has also tried to analyze the principle of system upgrading.

However, the conclusion is that the upgrade of the system is far from the high-tech stored as he imagined, and then upgraded and unlocked it step by step.

It's an escalation of the concept of even more terrifying.

To take the simplest example, if the system is a technological upgrade, then if Chen Xin has a stick, then he can choose to make this stick into a spear, club, sword or bow, and in subsequent upgrades, add new materials to replace it, and transform it into a more advanced one.

All this should have a context to be found and rules to follow, after all, the development of every science and 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 to make a certain object more powerful in the sense of concept and information.

Since this advanced civilization can modify the information contained in an item to make people think that it is reasonable, it can naturally also modify the information contained in the item to make it more conceptual, and Chen Xin's choice of upgrade plan is the process of giving concepts.
