The Zhou Dynasty-Skillful Use of Artificial Cold Source

The earliest "air-conditioned rooms" can be traced back to the Zhou Dynasty about 3000 years ago. At that time, nobles would build "caverns" underground, and adjust the temperature by using the natural temperature of the basement and filling the bronze ice mirror with ice cubes. , Summer important dining activities and entertainment activities will be arranged in the cool cave room.


In summer, where did the ancients get the ice? Every December, the bullies collect and store ice cubes, and then take them out the next summer for the princes and nobles to use. In addition to adjusting the room temperature, the bronze Bing Jian with ice cubes can also be used to chill drinks, fruits and vegetables, etc. It can be described as the earliest refrigerator in the world.


The Han Dynasty-Refrigeration Effect Upgrade

During the Han Dynasty, the configuration of air-conditioned rooms was upgraded by a large level. In the imperial palace of the Han Dynasty, there were "air-conditioned rooms" for winter and summer. The summer room is called "Qingliang Hall", and the winter room is called "Wen Tiao Hall". The cooling equipment in the Qingliang Hall includes: a natural stone bed, an imported jade crystal plate with ice cubes, and an attendant facing the jade crystal plate fan with a cool breeze.


The Tang Dynasty-Mechanical Device Refrigeration

In the Tang Dynasty, the "air-conditioned room" was upgraded again. The Hanliang Hall with "air-conditioning" function is the sleeping hall of the concubines of Tang Dynasty. It is built near the water and has a mechanized refrigeration device. "Water-induced fan", that is, the fan blades are rotated by water energy, and the fan blows against the cold water to form air-conditioning. The craftsmen also installed water pipes on the four eaves of the palace to lead the water to the eaves. The cold water circulates down the house to form a curtain of water. The interior is naturally cool and pleasant.


Now-HVAC Environmental System

With the continuous development and progress of science and technology, there are successively electric refrigeration equipment: electric fans, air conditioners, air coolers... But soon they were defeated by the new HVAC system. You must have had such an unpleasant experience. The cool air cooler has high humidity, makes the joints uncomfortable, damp and heat difficult to sleep, and finally falls asleep in the middle of the night and wakes up by the air conditioner. The airtight air-conditioned room is filled with unpleasant odors.
