With the increase of the new generation of Chinese population and the gradual increase in the income level of working people, most families have already saved a certain amount.

Although Huaxia Guo built the kindergarten, it also reduced a great burden on these families with children.

But kindergartens are not nurseries after all, and these children still need their parents to take care of them after school.

The old shared living conditions are no longer suitable for these families with children.

More and more families with children are in urgent need of more relaxed living conditions.

According to the application of some full members, the Ministry of State-owned Assets Supervision and Administration had no choice but to expand four more urban units in the center of the four sides of Huaxia City.

Since a large number of elevators of the same brand have been purchased during the construction of the Tuvalu Special District in the real world, it is not a big deal to transfer several sets of equipment over.

These sets of equipment were used by Huaxia technicians to engage in scientific research, from large to small parts were dismantled, and their specific role in the operation of the equipment was clarified according to the relevant information.

The unified procurement behavior enhances the interchange maintenance rate of equipment components and reduces the operation and maintenance spare parts of equipment.

After cultivating a certain number of elevator maintenance personnel, it is possible to use elevators in Huaxia City.

As a result, the four newly planned urban units were all built in accordance with the complete design standards of 15 floors above ground and 3 floors underground.

Due to the unusually developed public canteens in Huaxia, almost no one is willing to make their own food at home.

Even if it's a personal hobby, you can turn it into your own career, or you can pre-order the ingredients for the relevant dishes on the online platform first, and then borrow the kitchen yourself to show off your skills.

Due to the existence of public canteens, the vast majority of food waste is properly disposed of.

Therefore, the amount of domestic waste generated by Huaxia City every day only accounts for one-fifth of the amount of a city of the same size in the real world.

Moreover, since this daily waste is not mixed with perishable food waste, the amount of work required for sorting and disposal is smaller, and the rate of recycling is higher.

The clean and hygienic urban environment, comfortable and relaxed pace of work and life, have made the residents of Huaxia City feel the benefits of public canteens.

As a result, all of the new urban units still have kitchens out of all the housing.

The original kitchen space was converted into a nursery or other functional rooms such as a laundry room or storage room.

At the same time, because most of the places where everyone receives guests are in the Huaxia canteen.

It doesn't cost much Huaxia coins to book a private room.

The use of private rooms is calculated according to the time of day, and it is only 10 yuan per hour during the peak period, and only 5 yuan per hour during other periods.

The private room is also equipped with an IPTV, which is more than just a place to eat.

Order some different grades of tea and drinks in the canteen, which is a good place for casual chatting.

Therefore, the living room that is too large in the house does not make much sense to these residents of Huaxia City, and many families use the living room as a bedroom.

Most of the families who are willing to live alone choose a two-bedroom, one-living room and one-bathroom house.

Such a house is enough for a family of five or six people, and the price is not expensive.

Judging from their work income, such a small house of 60 or 70 square meters can live in a year with a family income of just over a month.

If you are willing to pay for it, you can rent a house of hundreds of square meters with a family income of about two months.

The larger the area and more rooms, the more imagination can be used.

The four newly built urban units, due to the increase in floors, provide a total of nearly 200,000 houses for living, as well as more than 400,000 square meters of commercial space and more than 1 million square meters of underground space.

Such a large housing investment fully meets the housing needs of those members.

As a result of the large number of lease changes by these full members, there has also been a significant reduction in the density of living in the original eight urban units.

However, after the original members of the shared house left, it was a bit wasteful for a family of two or three people to use a house of nearly 100 square meters.

Therefore, some families are looking for suitable co-tenants again through online platforms.

The Ministry of State-owned Assets Supervision and Administration has also froze some houses in communities with a small population in a timely manner according to the information fed back by the online platform, and will no longer rent them out to the outside world for the time being.

At the same time, the residents of these communities were resettled in nearby neighborhoods, and then the buildings that had previously only been built with only seven floors were heightened.

The superiority of the steel structure integrated house has been perfectly interpreted at this time, after simply removing the roof, the new floor unit produced in accordance with the unified standard is installed on the original structure, and the height of the building is realized.

There is no demolition, no unbearable noise, and no large amount of construction waste and dust pollution.

Even, if it were not for the consideration of production safety, there was no need for the residents of the original houses to be cleared out.

Due to the real-world construction experience of China's Valu Special District, these new or renovated high-rise buildings in Huaxia City have not encountered any unsolvable difficulties and problems.

However, due to the difference in climate between the two places, the temperature inside the building is adjusted in a slightly different way.

On the roofs of these high-rise buildings in Huaxia City, hot and cold water storage tanks and heat pump exchangers are still set up to convert tap water at room temperature into a medium with a large difference between hot and cold.

Cold water with a temperature of about 10 degrees Celsius can be used as a cooling source in summer when the indoor temperature is too high, while hot water with a temperature of about 60 degrees Celsius can be used for daily life.

But in the cold winter, due to the limitation of ambient temperature, these equipment in Huaxia City cannot play a better heating role.

Therefore, Wei Minsheng connected to the boiling water room of the community canteen through the circulating pipe of the hot water storage tank.

A passive heat exchanger is used to transfer heat from a large amount of hot water in the boiling water room to the circulating water to increase the temperature of the hot water in the storage tank.

Because the water temperature in the boiling water pot is difficult to boil under the action of passive heat exchanger and circulating water, it is not easy to produce scale.

The vacuum-type automatic water feeding equipment can ensure that there will be no shortage of water in the boiling water pot at any time throughout the day, and has a higher safety factor.

The use of hot and cold water as a medium to regulate the air temperature is the safest.

In addition, the maintenance of hot and cold water pipes is also simpler and does not require professional tools and technicians to manage.

Just using some biogas or straw gas, as well as boiling water equipment in the canteen, the purpose of increasing the water temperature in the storage tank is achieved.

Hot water with a temperature of more than 80 degrees Celsius can be easily raised by the water air conditioner installed in each room, which can easily raise the temperature of any room in the whole building, thus making up for the shortcomings of the poor heat pump effect in winter.
