Chapter 103

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

At first glance, it seems very magical, a bit like civil science cheating people, but in fact, it is a real technology, and things that can achieve this efficiency can be found everywhere in our lives, the most representative of which is air conditioning.

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

Among them, the energy efficiency ratio of electric heater, that is, direct electric heating, is the lowest, only about 60%, that is, it consumes 1kW · h of electric energy and 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. 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 the electric boiler is quite high, which can reach 0.95, that is, the so-called direct use of electric oven is not as good as using fast heating to boil water.

It's very efficient to achieve an energy efficiency ratio of 0.9. After all, the law of conservation of energy is stuck here and can't reach 1 in any case.

But 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 refrigerant to carry the indoor heat to the outdoor, the heat driven by it is not generated by it, but exists in itself, and the air conditioner only carries it.

In fact, in China, 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 with an energy efficiency ratio of more than 3.2 can be called air conditioners in the true sense.

And understand this point, ground source heat pump can achieve 4 energy efficiency ratio is not uncommon.

As for why air conditioning and ground source heat pump can achieve such energy efficiency ratio, it is because they all have a series of equipment including compressor, evaporator, condenser and expansion valve, which is much more complex than boiler and other equipment.

But just because of a set of complex equipment, it also brings considerable energy.

Using 1kW · h electricity to bring 4kw · h heat is obviously input > output.

Looking at the data, Chen Xin has an idea in his mind. He finds a piece of paper and a pencil and plans 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's more profitable than directly using the electric heater or electric boiler..." Chen Xin scribbles on the paper. He doesn't want to draw anything. It's just a tool for thinking: "if half of the heat is used for heating, the remaining half is used for power generation..."

It doesn't matter what is painted on the paper. What is important is what Chen Xin is thinking about. With his thinking, there is a ray of light in his mind!

"No matter how low the efficiency is, as long as there is an energy efficiency ratio of 0.6, the system can run on its own!" Chen Xin slapped the table hard, and the whole person was excited.

This is not a bullshit perpetual motion machine. It's just a common waste heat recovery power generation in industry. Of course, Chen Xin's waste heat recovery is a little too much, enough to make this set of equipment self-sustaining.

It is not difficult to achieve this, because after the refrigerant brings heat from the stratum, it needs to evaporate and release a lot of heat. In this process, whether Chen Xin is preparing to boil water or thermoelectric power generation, it can generate enough power to maintain the operation of the whole system, and there is enough heat for heating.

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

This can be seen from the fact that Chen Xin's shelter can still have a temperature of 7 ℃ when the external temperature is - 34 ℃. If the ventilation system is not constantly ventilating, causing a certain loss of heat energy, the temperature of the shelter can actually be a little higher.

So if Chen Xin wants to use the ground temperature, he doesn't need too much trouble. He just needs to bury the pipes in the ground, or even directly into the soil of his greenhouse.

Although it is possible to reduce the soil temperature of greenhouse and affect the growth of crops.

But Chen Xin can just build the system in the soil layer where the greenhouse is planted, and then use the system upgrade to re plan, burying the pipeline into a deeper layer.

In fact, Chen Xin's entire refuge is wrapped in thick reinforced concrete and thermal insulation layer. If Chen Xin wants to bury the pipeline in the real stratum, he needs to pierce through at least 40 cm thick reinforced concrete.

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

After having the system, all Chen Xin needs to do is upgrade it 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 so many different patterns and exchange functions of other systems, it is such a simple function. If you use it well, you can play with it.It's true that the system can't change things out of thin air, it must have basic items as the basis, but in fact, the upgrade of the system is still very terrible.

Chen Xin is a novelist, and novelists are monsters with black holes above their necks. In addition, he likes to think, so Chen Xin has tried to analyze the principle of system upgrading.

However, the conclusion is that the upgrade of the system is far from what he imagined. He stored high technology and then upgraded and unlocked it step by step.

It's a more terrifying concept upgrade.

For the simplest example, if the system is upgraded by science and technology, then if Chen Xin has a tree stick, he can choose to process it into spears, sticks, swords or bows and arrows. In the subsequent upgrade, he can add new materials to replace it and make it more advanced.

All these should have context and rules to follow. After all, the development of every science and technology must have its own pre science and technology.

However, although the upgrading of the system seems to be the same, it is actually much more terrifying, because according to the function of fuzzy concept of information state attached to the system, Chen Xin analyzes that the so-called upgrading of the system is to make an object more powerful in the sense of concept and information.

Since this higher civilization can modify the information contained in an article to make people think it is reasonable, it can also modify the information contained in an article to make it more conceptual. Chen Xin's choice of upgrading scheme is the process of giving concepts.
