Although there was also a "refrigerator" in ancient times, but the modern refrigerator in Chen Youxin's eyes, it is still very magical, open the door of the refrigerator, and find that it is divided into two layers, the upper floor is the refrigerator, I heard Hong'er introduce that it is mainly to put some fruits and vegetables, and the lower layer is the freezer, which can freeze some fresh fish and meat.

It's just that these refrigerators are now available on Dongluo Island, and after everyone gets used to it, they don't feel particularly magical, and they no longer feel like they were facing the TV and stereo just now, and they feel like they are "snatching people's hearts", but no matter what, these magic weapons still make them feel what it means to be "ingenious".

After all, after the electricity was turned on, the refrigerator that was opened, its freezer, everyone put their hands into it, and after a while, they felt "freezing and piercing", and they recycled their hands back, and they had to rub their hands to warm up.

As for the magic device of "air conditioning", according to Hong'er, the function of this electrical appliance is to regulate and control the air temperature, humidity and cleanliness inside the house. It is generally the most convenient to use on a hot day, which can make people feel that the room is immediately cool, just like the "Hanliang Palace" in the Tang Dynasty. It can also be used in winter, and it can make people feel that the room is immediately warm, just like the effect of the "fire kang" in the north.

"Hanliang Palace" is the name of the "air-conditioned room" in the Tang Dynasty, but in the Han Dynasty it was called another name, when the palace had a "air-conditioned room" for both winter and summer. In winter, the room is called "Temperature Adjustment Palace", and in summer, it is called "Cool Palace", and the Cool Hall is also called "Yanqing Room", which is the highest level of summer shelter for the royal family. Judging from the records of the Book of Han, the refrigeration effect of the Qingliang Hall is excellent, and it is called "the room is frosty in the middle of summer", which means that the room can be frosted in the middle of summer, and the temperature of the room is described as low as follows.

Moreover, the cooling equipment attached to the "Cool Hall" is also extremely luxurious. The entry for "Qingliang Palace" in the anonymous ancient book "Sanfu Huangtu" has such a record, "with the painting stone as the bed, the text is like brocade, the purple glazed tent, the purple jade is used as the plate, such as Qu Long, all decorated with miscellaneous treasures", "and the jade crystal is used as the plate, the ice is stored in front of the knee, and the jade crystal and the ice are clean".

The stone high-end bed itself is a good product for summer, and there is a jade crystal plate imported from abroad containing ice cubes placed next to it. Of course, what is even more amazing is that the waiter is also allowed to stand next to him and fan the master on the bed. With such a enjoyment and multiple cooling, it is naturally extremely cool and comfortable.

In the Tang Dynasty, the air-conditioned room renamed "Hanliang Palace" was renamed "Hanliang Palace", and the refrigeration means were more advanced, and the cooling was achieved through mechanical devices. In "Tang Yulin? It is recorded in "Haoshuang" that at that time, Cheng Zhijie gave Tang Xuanzong Li Longji a sparse visit, and Li Longji asked Gao Lishi to talk to him. At that time, it was a scorching hot weather, and Li Longji moved his "office" to the "Hanliang Palace" to escape the heat. Cheng Zhijie saw the sage Li Longji "behind the seat of the water fan car, the wind hunts the clothes". After entering the "Hanliang Palace", Cheng Zhijie was "given to sit on the stone couch" by Li Longji, and felt that the whole room was "gloomy and silent, looking up and not seeing the sun, and the water in the four corners was splashed into a curtain, and the seat contained freezing." ”

Judging from the historical records of this paragraph, this "Hanliang Palace" is in terms of architectural design, first, it can avoid direct sunlight from shining in, so it looks very gloomy indoors; The second is that there was already an "electric fan" at that time, of course, the use of modern electric energy was not used, but the water energy of the rockery waterfall, using flowing water to rotate the fan blades, so that the "water fan car", the fan then blows on the cold water, it forms a cold air; The third is to build a circulating cold water source in the hall, so there is flowing water flowing down on all sides, forming a water curtain, like the water curtain hole in Huaguo Mountain.

The structure of the "water curtain" is actually very simple, that is, water pipes are installed on the four sides of the eaves of the palace, and then the water is directed to the eaves. Then the cold water circulates in the house, and the indoor temperature naturally drops, and the cooling effect is excellent, achieving the refrigeration effect of "freezing in the seat".

This kind of "air-conditioned building" is called "self-pavilion" in folk, and is also known as "rain pavilion". At that time, the homes of high-ranking ministers also had such "air-conditioned rooms", such as the home of Jingzhao Yin Wangji, which had a "self-pavilion". The cooling effect of the "self-pavilion" can be described as excellent, so there is a poem "When the summer is located, it is like a high autumn".

However, according to the research of modern scholars, this kind of refrigeration and air conditioning technology containing mechanical principles was not invented and first used by our Chinese, it originated from the country of Fu, that is, the Eastern Roman Empire, when the palace of the country of Fula had this kind of "air conditioning". If this research is true, then this device should be the earliest "imported air conditioner" in China.

As early as around 1000 B.C., the Persians had invented an ancient air conditioning system, which used a wind pole installed on the roof to let the natural wind from the outside pass through the cool water and blow into the room, making the people inside feel cool, and later improved by the craftsmen of the Eastern Roman Empire, and then introduced to China.

When the time entered the Song Dynasty, the "air-conditioned room" in summer was further improved. Like the retro hall, the selection of the hall and the cuihan hall is the Song Dynasty palace in the summer resort, according to the "martial arts old things" in the "forbidden to enjoy the cool" record, the environment of these places are quiet and pleasant, surrounded by "long pine and bamboo, thick green cover the sun, layers of mountains and strange Xiu, quiet and deep, cold waterfall flying in the air, bet on the big pond can be ten acres".

And the means of cooling in the palace in the Song Dynasty were more advanced, and they invented the "electric fan" with mechanical principles, which was driven by a blower, so it is said that "the drum is a wind wheel". The fan of the "wind wheel" blew directly on the hundreds of pots of flowers placed in the hall, and suddenly it was "Qingfen full of halls", and on both sides of the throne, there were also "dozens of golden pots set up, and the snow was like a mountain". In this way, man and nature are more harmonious, and it also reflects the luxury of the palace.

Later in the Ming and Qing dynasties, compared with the "air-conditioned room" in the Song Dynasty, in addition to the basic cooling means, the air purification method was also adopted to blow incense, so as to improve the air quality in the "air-conditioned room", then the summer cooling method of the royal palace in the Ming and Qing dynasties also has its own characteristics.

The most special thing is that there is a "movable" cold source in the room, which is a bit like a modern split air conditioner or air cooler. This "movable" cold source is sometimes called an "ice bucket", and modern people jokingly call it a "refrigerator".

The "Ice Bucket" is a wooden structure, and its design principle can be traced back to the Shang and Zhou dynasties of the bronze "Bingjian", as mentioned above, the "Bingjian" is the most primitive refrigerator. The "ice bucket" looks simple now, but in the Ming and Qing dynasties, it could be regarded as a high-end "household appliance".

In fact, it is more accurate to call an "ice bucket" or "freezer", which is actually a cabinet for storing ice cubes, which is hollowed out and used as an air vent for air conditioning. The central space can also be used to store food, such as chilled watermelon or a variety of cold drinks. Later, "ice buckets" also became popular among the people, and there were also "imported goods", which were called "foreign barrels".

Huang Shi still remembers that in the early 80s of the last century in China, there was a Japanese TV series "Ashin", which swept the country and made a generation of Chinese remember Ashin, a woman who went from difficulty to success, but he remembered a detail in the TV series at that time, when Ashin bought a refrigerator, which is actually a real "freezer", and put ice cubes in it when he used it.

Of course, all kinds of "air-conditioning" facilities on this are not affordable for ordinary people in ancient times, or they have never even seen or heard of it, for example, Chen Youxin, who is a maritime merchant, is very rich, and he has never seen this thing.

Not to mention the others, after listening to the effect of this magic weapon, it was breathtaking, in the past, they could only sit quietly under the canopy of the tree in the summer, waving the fan, waiting for the cool breeze to blow. However, this magic weapon invented by the immortals can make people sit at home and refresh themselves for a summer, which is really extremely happy.

Only Li Chengpeng is an exception, although he has not seen it, but he is full of scriptures, well-read and strong, although he is not rich in learning and five cars, only eight buckets high, but it is also well-read, erudite and knowledgeable, this "there are thousands of Zhongsu in the book, there is a golden house in the book, and there is Yan Ruyu in the book", so Li Chengpeng still remembers what the Tang Dynasty poet Zhang Zhongsuo said in the poem "Music in the Palace", "The red fruit Yao Chi is real, and the gold plate is dew well ice; Ganquan will escape the heat, and the light of the temple will be condensed", what he described was the scene of the summer in the "Hanliang Palace".

Fortunately, although the people can't afford these high-end "air conditioners", they also have their own local methods, such as Cao Cao's then, the "ice well platform" that built a large cold storage in Yecheng, that is, digging a deep well to collect cold air, digging a deep well in the hall or the room where it is needed, and then covering it with a lid, and then digging holes in the cover, so that there will be cold air from below in summer, and there will be heating in winter to ensure that the temperature of the hall is relatively stable and pleasant.

But these facilities are generally large households, can have such economic conditions, in the preserved Ming and Qing dynasties, Anhui and southern Anhui ancient Hui merchant houses, you can often see this kind of "earthen air conditioning", they can not only cool the room, but also as an underground "refrigerator", put the food into the well to keep fresh, refrigerated, can keep the food fresh for a long time.

And there are also large families to build a basement similar to the "cave room" in the pre-Qin period, this kind of room is called "earth room" in the Ming Dynasty, a bit like a cave, but not exactly, "earth room" is similar to an authentic building, and the earth room of each family is connected by a tunnel.

In Mingren Xie Zhaoqian's "Five Miscellaneous Works? There is a record in the "Earth Department", "earth room" is a winter and summer dual-purpose, belongs to the multi-functional room, and has the function of anti-theft and anti-bandit, "to the near edge of the city, often make an earth room to avoid it, if the building, the end of the room is in it, seal its tunnel, it is no less than a golden soup." ”
