Chapter 102: Ground source heat pump technology

According to the law of conservation of energy, it is impossible to generate heat with 1kW·h of electricity to produce more than 1KW·h. However, if ground source heat pump technology is used, 1KW·h of electricity can be used to generate 4KW·h of heat. Or cold capacity.
At first glance, this may seem magical, and it feels a bit of a silly folk science, but in fact, this is a real technology, and things that can achieve this efficiency abound in our lives, the most representative of which The one is air conditioning.
　　 In thermodynamics, the ratio of energy conversion efficiency is called the energy efficiency ratio COP.
　　 Among them, electric heaters, that is, direct electric heating, have the lowest energy efficiency ratio, only about 60%, which 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 depending on the fuel. 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 boilers is quite high, which can reach 0.95, which is the so-called direct use of electric ovens. It is better to boil the water quickly.
　　 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 cannot reach 1 anyway.
　　 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 a refrigerant to transport the indoor heat to the outside. The heat it drives is not generated by it, but exists in itself. The air conditioner just carries it.
　　In fact, in Yan Country, air conditioners with an energy efficiency ratio of less than 2.6~2.8 are not allowed to go on sale at all, and only those with an energy efficiency ratio of 3.2 or higher can be called air conditioners in the true sense.
　　Understanding this, it is not uncommon for a ground source heat pump 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 more complicated than boilers and other equipment. a lot of.
　　 But just because of a complete set of complex equipment, it also brings considerable energy.
　　Using 1KW·h of electricity to bring 4KW·h of 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 scribbled on the paper casually, he said It’s not something to draw, it’s just a tool for thinking: "If half of the heat is used for heating, the remaining half is recovered and used to generate electricity..."
　　 It doesn't matter what is drawn on the paper, what is important is what Chen Xin is thinking about at this time. With his thinking, there is a glimmer of light in his mind!
　　 "Even if the efficiency is low, as long as it has an energy efficiency ratio of 0.6, this system can continue to 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 it is a very common waste heat recovery power generation in the industry. Of course, the waste heat recovered by Chenxin is a bit too much, and it is enough to make this equipment self-sustaining.
It is not difficult to achieve this, because the refrigerant needs to evaporate and dissipate heat to release a large amount of heat after bringing heat from the formation. In this process, whether Chen Xin is preparing to boil water or generate electricity by temperature difference, it can produce There is enough electricity to maintain the entire system, and there is enough heat for heating.
　　 As for what needs to be drilled into the stratum to realize this system, Chen Xin lives in an underground refuge. 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 Chen Xin’s refuge can still have a temperature of 7°C when the outside temperature is -34°C. If the ventilation system is not for continuous ventilation, it will cause a certain amount of heat loss. The temperature of the refuge can actually be higher.
　　 So if Chen Xin wants to use the ground temperature, it doesn't need to be too troublesome. He just needs to bury the pipes in the ground, or even directly into the soil of his planting greenhouse.
　　 Although doing so is likely to reduce the ground temperature of the soil layer of the planting greenhouse, affecting crop growth.
　　 But Chen Xin can just build this system in the soil layer of the planting greenhouse, and then use the system upgrade to re-plan and bury the pipeline in a deeper layer.
In fact, Chen Xin’s entire refuge is surrounded by thick reinforced concrete and thermal insulation. If Chen Xin wants to bury the pipeline in the real ground, he must penetrate at least 40 cm thick reinforced concrete. of.
　　 If there is no system help, Chen Xin will give up this idea directly.
　　 After having the system, all Chen Xin needs to do is to upgrade with the system. UU reading www.uukanshu.com
By now, Chen Xin has thoroughly understood the horror of this system. Although there is only a simple upgrade function, there is no such a variety of tricks and exchanges as other systems, but it is such a simple function, if it is used well You can play with flowers.
　　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 wrote novels, and the novelists are all monsters with black holes above their necks, and he also likes to think, so Chen Xin also tried to analyze the principles of system upgrades.
　　 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 it step by step.
　　 is a more terrifying concept upgrade.
To give a simple example, if the system is a technological upgrade, then if Chen Xin has a tree stick, then he can choose to process this tree stick into a spear, a stick, a sword or a bow and arrow, and in the subsequent upgrade, add New materials replace them and make the transformation more advanced.
　　 All these should be traceable and rules to be followed. After all, the development of every technology must have its pre-technology.
However, although the upgrade of the system seems to be the same, it is actually more terrifying, because according to the fuzzy function of the information state concept attached to the system, Chen Xin analyzed that the so-called upgrade of the system is a conceptual and informational change. An object becomes stronger.
Since this advanced civilization can modify the information contained in an item to make people think 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 the upgrade plan, It is the process of giving concepts.
