Western Union Vocational University.

Faculty of Energy Engineering, Department of Energy Control, Energy Equipment Research Class 5.

Forty-nine vocational college students, who have been downgraded from sophomores in ordinary colleges and universities, are following professional tutors to visit a row of metal cabinets that are two meters high and one meter wide.

His mentor is tall and tall, with a shawl and gray hair, and he is a Taoist leader.

"Students, as we all know, heat energy can be spontaneously transferred from a high-temperature object to a low-temperature object, but it cannot be spontaneously reversed. ”

"And these cabinets in front of us are mechanical devices that force heat to flow from low-temperature objects to high-temperature objects in a reverse circulation way. ”

"It's called a 'ground source heat pump', and it's a type of heat pump system. ”

"Heat pumps originated in the seventies of the last century and work similarly to those of refrigeration systems. ”

"The principle is in the textbook, so I won't talk about it here, just remember its operating formula, that is, from the low-temperature heat source (outdoor air or circulating water, the temperature of which is higher than the evaporation temperature t0) to obtain Q0 kcal/h heat, consume mechanical work ALkcal/h, and supply Q1 kcal/h of heat to the high-temperature heat source (indoor heating system), the relationship between these heat is in line with the first law of thermodynamics, that is, Q1 = Q0 + AL kcal/h. If the heat converted by mechanical work is not used without a heat pump device (or if the heat source is directly heated with electrical energy), the heat obtained is ALkcal/h. With a heat pump device, the high-temperature heat source (heating system) receives more heat: Q1-AL=Q0 kcal/h. ”

"This heat is obtained from a low-temperature heat source, which cannot be obtained without a heat pump unit. Therefore, the use of heat pump devices can not only save fuel, but also use waste heat. ”

It can also be seen that the minimum value of the heat conversion coefficient is φ = 1, and in this extreme case, ε = 0 and Q0 = 0, i.e. no heat is drawn from the low-temperature heat source. ”

"So, usually the cooling coefficient of a heat pump is about 3-4, that is, the heat pump can transfer 3 to 4 times the amount of heat energy it needs from a cold object to a high temperature object. ”

Therefore, the heat pump is essentially a heat lifting device, which consumes a small part of the electrical energy when working, but can extract 4-7 times the electrical energy from the environmental medium (water, air, soil, etc.) to raise the temperature for utilization. ”

"That's why heat pumps are energy efficient. ”

"Since overseas heat pump research is 30 years earlier than ours in Huaxia, they can already achieve 6 times the refrigeration coefficient. ”

"And we Huaxia, from 01 Tiancheng decided to invest in the 'new energy project', following the river hydropower station, wind power station, solar energy and other projects, the 'heat pump system' was successfully developed in September 01, and commercialized this year. ”

"In 01, the refrigeration coefficient of Tiancheng heat pump system was only 3, at the end of 01, we increased the refrigeration coefficient to 4, 02 in the middle of the year to break through to 5, 03 in March, in the western development project, we broke through to 6 for the first time. ”

"Today, we have abandoned the first generation of heat pumps that used freon as a working fluid, and we have also abandoned the R23 and R417A that are common in overseas heat pump laboratories and switched to carbon dioxide. ”

"The transformation of working fluid has made another breakthrough in our heat pump research, and in September this year, the refrigeration coefficient was increased to 8, surpassing overseas, and becoming the most technologically advanced enterprise in the field of heat pumps. ”

"At present, in the field of Tiancheng engineering, heat pumps are mainly divided into air source heat pumps, water source heat pumps, ground source heat pumps, dual-source heat pumps (water source heat pumps and air source heat pumps combined), etc. ”

"If you can effectively use these heat pumps to build residential buildings, commercial buildings, large shopping malls, etc., no matter which area you are in, you can feel the 'constant temperature'. ”

"It is different from the third-generation commercial housing of Tiancheng, that is, the constant temperature house that can only be built south of the mother river and north of the Yangtze River due to geographical restrictions, and it is a 'constant temperature house' that can ignore the climate and region in the real sense. ”

"This is also the fourth generation of Tiancheng's commercial housing. ”

"When it is completed, the air conditioner will no longer consume a lot of electricity in the summer, saving users four-fifths of their expenses. In winter, heating companies will no longer be used for heating, and the cost of heating per square meter will be reduced by two-thirds. ”

"Students in need, or interested students, can pass on the relevant information to their parents, relatives and friends, and the super Xingyue Bay with a heat pump system will open on New Year's Day. ”

"Okay, that's all for today's class, the homework after class is, within three hours, borrow machinery and equipment, assemble 200 ground source heat pumps per person, and hand them over to the students of the 'Equipment Installation Department', and I will check them tomorrow morning. ”

Distance.

Ge Xiaotian led Dao Yi and the others, and they were also observing the 'ground source heat pump'.

The content of Daoyi's lecture is almost exactly the same as the course taught by the Taoist Teacher.

"In general, through the joint efforts of the teachers and students of the School of Energy Engineering, the main campus of the vocational university has been laid with the 'intelligent ground source heat pump system', and after a week, the commissioning is completed, and the effect of 'four seasons like spring' can be achieved indoors at low cost, no longer hot during the day, no longer cold at night, completely offset the negative impact of the desert climate, and the funds for the installation of air conditioning and the construction of heating stations are left. ”

"Where's the Sand City?"

"After completing the construction of the ground source heat pump on the main campus, the academic activities of the School of Energy Engineering will be transferred to Shacheng in the same way...... No, practice makes perfect, and we will open an internship site in Shacheng. ”

"You're a wicked headmaster. ”

Ge Xiaotian shook his head and sighed, boarded the special car, and went to the southern campus of United University, that is, the college of master's and doctoral studies.

The ground source heat pump is only one of the heat pump systems, which is produced, assembled and operated by teachers and students.

And in the system building, there is also a kind of heat pump called the 'energy heat pump'.

It's like after upgrading to a level 4 town center, the system starts to eat electricity, and correspondingly, various power plants appear in the system building list.

After upgrading the five-level town center, the system began to eat photovoltaic cores, and correspondingly, new energy things appeared in the list of system buildings, such as solar power generation systems, wind power towers, and energy heat pumps.

The energy heat pump is the 'source of energy' for the fifth-level town center, and there is no one.

Because the solar power generation system and wind power generation system cannot afford the huge consumption of electricity by the system at all.

Just like launching a space shuttle redeemed from the system, it takes 25% to manufacture alone, while 50% to launch, and 1% per day for daily operation.

Such a large power eater forced Tiancheng to shut down the functional buildings related to the system when carrying out aerospace projects, such as Taishi Smelter, Northeast Aerospace Manufacturing Plant, Sun Paper Processing Plant and so on.

Therefore, every time Tiancheng carries out an aerospace project, Tiancheng industry will have a long vacation.

Next, Tiancheng will start a series of space exploration projects, in order to avoid affecting production, it is imperative to build an 'energy heat pump'.

However, the 'energy heat pump' system unit not only covers the highest area ever, covering almost 40,000 square kilometers, but also has very demanding construction requirements.

There must be low energy in range.

The site must be evenly distributed.

There is no need to use a think tank, Ge Xiaotian himself thought of the desert.

The reason why the desert is 'hot in the day and cold in the night' is mainly because the fine sand dissipates heat quickly and cannot store heat energy like water and soil.

This is a low energy source that volatilizes energy all the time.

The desert is the flattest of all the terrain and landforms of the home planet, at least the plains have hills and rivers.

In fact, it was built successfully.

Of course, covering an area of 40,000 square kilometers, it does not mean that the system unit of 'energy heat pump' is as large as 40,000 square kilometers.

It is divided into 40,000 modules, with an average of one per square kilometer, and the appearance of a single container resembles a large container, and the whole is like a wind turbine tower on the grassland, and 40,000 modules are evenly distributed in the desert of 40,000 square kilometers.

It provides 5% of the energy to the system every minute.

Awesome!

It is more powerful than all the power systems in Huaxia combined.

However, this energy can only be used by system units, and cannot be applied to real units.

Because Tiancheng has not developed a 'heat pump power station', and exchanging a rare metal that requires 5 million units is ten times more expensive than exchanging for a space shuttle, which is roughly equivalent to ...... 1 unit = 50 grams of gold, 1 gram of gold is currently rising to 260 red banknotes, about 650 billion red banknotes.

However, the system must be a high-quality product, if there is a heat pump power station, Tiancheng can build a power plant on the moon, after all, the surface there, full of solar radiation, is also a low energy source.

In the same way, Tiancheng can also place the power station on Mercury and Venus, where the temperature is relatively high, to complete the extraterrestrial energy construction project.

It's a pity that there is no money.

No, it's no gold.

It is also impossible for Ge Xiaotian to smash the limited gold of the home star on this before discovering the alien gold source.

In addition, the non-district is working on the 'H fusion' technology that belongs to the sixth-level town center, which is more powerful than the 'heat pump power station'.

Of course, he and Daoyi plan to skip the sixth level and advance to the first level of cosmic civilization, and the reason why they built the 'energy heat pump' is to solve the energy crisis and study the efficiency of energy utilization.

In 99 years, China's energy utilization efficiency, including processing, transportation and use, was only about 32%, more than 10 percentage points lower than that of advanced countries, and if it was multiplied by 32.1% of the energy exploitation efficiency, the total energy utilization efficiency was only 10.3%, less than half of that of advanced countries.

03, under the promotion of Tiancheng, the total energy utilization rate has increased to 22%, but it is still low.

Dao Yi suspects that the condition for advancing to the first level of cosmic civilization is to increase the total energy utilization rate to 60%.

It's a terrifying and almost impossible number.

But who made this a first-level cosmic civilization?

............

After a short time, the special car arrived at the control center of the 'energy heat pump'.

Ge Xiaotian walked into the hall, and more than fifty monks in white coats were operating various instruments.

Daoyi was worried that this guy couldn't understand, and explained: "We are copying the automatic control system of the main brain, after eating thoroughly, it will be transplanted into the imitation of a small energy heat pump, test its comprehensive ability, if successful, add a steam turbine, generator, you can imitate the 'heat pump power station', of course, its energy efficiency, certainly not as good as the finished product of the main brain, but it can also reach 70%. ”

"Exceeding your prediction of 60% of the upgrade conditions, which is good. ”

"But just like putting you and Da Yao together, you have lowered the average height of Huaxia. ”

"Why am I 1.88 meters tall, and you actually say that I have lowered my average height? Do you know where the second machine went?"

"Ceres. ”

"Do you want to go?"

"It's minus eighty or ninety degrees there, and the ghost wants to go. ”

“......”

The scientific researchers' focus on technology is definitely not as smooth as Dao Eleven, who has various communication skills, and Ge Xiaotian is too lazy to bother with Dao.

After a short walk in the control center, I realized that I couldn't read at all, and pretended to be 'I know a lot' and came to the office.

'Energy heat pump' is a device that provides energy, which Tiancheng has not yet mastered, but such as air source heat pump, ground source heat pump, etc., has long been understood.

Nowadays, these 'low-energy absorption heat pumps' have become a weapon for Tiancheng's new round of real estate development.

In addition, it can enhance the overall energy efficiency of its own industry.

Watch the big boss start the stone light machine, and then open the industrial strategy map of Tiancheng International Holdings.

Dao 11 reported: "The first batch of super Xingyue Bay using heat pump system are located in Heilong Bingcheng, Qiqiha, Jiamu City in the northeast, Ordos in the grassland, Zhangjia City and Chengde in Beihe, Xuecheng in Zao City in Dongshan, Xucheng in Jiangsu and Zhejiang, Xudu in Nandu, Kuncheng and Yuxi in Nanyun, and six cities in Guangzhou. A total of 54,700 commercial houses, 32,300 street-facing shops, with a total value of 174 billion red banknotes, and estimated sales of ...... Fourth in the country. ”

"Huh, fourth?"

"Well, according to the big data summary, the first place is Daheng, the second place is Kewan, who has entered the country, and the third place is your old rival, Shen Zhipeng's Ginza. ”

"What about the fifth?"

"'Dadi Poly', which was reorganized by two large real estate companies, and 'Zhonghai Longhu', which was also reorganized by two large real estate companies. ”

"Times have changed. ”

"House prices haven't changed. ”

"Yes. ”

Ge Xiaotian still cared about the 'first' two years ago, because Tiancheng needed publicity at that time, but now ......

Take a look at the top 100 in China, there must be a few that don't start with the word Tianzi.

The most important thing is that this year, Tiancheng aims at the overseas market.

"What about overseas real estate?"

"A total of 650,000 units of ordinary commercial housing have been completed, with estimated sales of 295 billion Franklin. In addition, some industries, such as the Non-District Alliance, Neoblas, Montenegro Odyssey, and Nanyang Rubber Plantation, all adopt the labor division system, which is converted into sales, which is about 3 trillion Franklin. The profit ratio has been maintained at 65%. ”

"In the future, 50% will be maintained, and the extra 15% will be used to reward overseas employees. ”

"Good boss. ”

"By the way, what about the money? How did I find out that whether it is domestic or overseas, the account funds are one or two hundred million?"

"You don't spend money to buy gold, you don't spend money to repay international bank loans?"

“......”

"However, the funds lent to futures players have not yet been recovered, strictly speaking, the total funds in our account should be 370 billion Franklin, in addition, some time ago the North American Tianchuang was sold to the Holden consortium, and they used the funds to help us buy 270 billion Franklin worth of minerals from the rich people who bought the tickets, speaking of which, I must remind you that the night is long and dreamy, you need to go to North America as soon as possible and take the opportunity to recycle the minerals. ”

"Build a mining farm over there, and let the strong man who plays Huo Dun's security guard move things in. ”

"Then you have to arrange for a town center to go there, otherwise, how can you build a mining farm if you are not in control?"

"Town Center ......"

Ge Xiaotian opened the system list and counted roughly.

There is only one small town center, the main town center, which is now a professional college town, with five doppelgangers, one to the moon, one to Ceres, one to be placed in the space shuttle, one in the space station about to go to space, and the last one in the South Pole.

In the remaining town centres, one is in the non-district district, which is the capital of the non-district union, another is docked on the coast of Dubai, and the others are located in the various overseas bays of Xingyue Bay.

If you have to settle a town center in North America, you can only go to the 'Engineering Island'.

But such a big guy, especially in the time period just after the big exercise, went straight to North America......

Moreover, when fighting Ira in North America, to avoid being attacked by the other party, it is also loaded with a large number of Tiancheng's most advanced super panda modifications, drones, and mechanical legs.

If the other party finds out, I'm afraid that I will fight on the spot.

"Organize an Antarctic expedition, send an engineering island clone over, take the opportunity to replace the main town center clone in Antarctica, and then send Chen Feng to North America. ”

"It's fine. ”

The road nodded a little, and contacted the Sea of Okhotsk, where a vacant engineering island clone was docked.

Just when the two of them were ready to go their separate ways......

A system prompt suddenly popped up in Ge Xiaotian's mind.

"Countdown, 19 days: 23 hours: 59 minutes ......"

The next moment.

A panoramic diagram of the universe appeared in Ge Xiaotian's field of vision.

"Within the allotted time, find your own planetary location, and you have a certain chance once a day, which resets every 24 hours, for a total of 20 sure chances. If successful, you will be promoted to a first-level cosmic civilization and receive a fourth-year anniversary reward. If you fail, you will be promoted to the sixth-level town center, and the next promotion will require you to have controllable H fusion technology. ”

Daoyi seemed to find something, "Boss, it's up to you, with our current technology tree, it will take at least 15 years to complete controllable H fusion, and you can't afford to wait." ”

"What the hell am I ...... Have you ever seen Venus in two eyes? No, my eyes are full of light, and the devil knows which one is our planet. ”

"Have you forgotten the star map I've been letting you see lately? first look for the Virgo Cluster of Galaxies, then the Home Cluster, then the Milky Way, the Solar System, ......."

"No, I suspect that the universe map given by the system is not from our time and space. ”

“？？？”

"I've found the solar system, but the parent planet of this solar system ...... The non-Eurasian plate has not yet been separated. ”

“......”
