摘要： An air control system and method using air in an upper zone of the atmosphere are disclosed. An air control system using air in an upper zone of the atmosphere includes: a floating body 11 provided to stay in the upper zone of the atmosphere; air transporting pipes 15a and 15b interlocked with the floating body 11 to transport air in the upper zone of the atmosphere; blowers 22a and 22b mounted below the air transporting pipe 15a and 15b; and an air transporting controller 18 controlling an operation of the blowers 22a and 22b. According to the embodiment of the present invention, it is possible to implement functions such as cooling, drying, and purifying of the surrounding air, removing mist, or generating clouds through the transport of dry and low-temperature clean air in the upper zone of the atmosphere with a simple structure. In addition, according to the embodiment of the present invention, it is possible to freely adjust a height of air control because there is no need to install a post tower to support an elevating device because it supports the floating body 11 on the ground without the post tower.

摘要： An underground heat exchange system is provided to reduce energy consumption for circulation of a heat transfer medium and reduce construction, management, and maintenance costs. The underground heat exchange system includes: a double-pipe heat exchanger that is buried underground to convert a heat transfer medium into a usable form; a medium collector that collects the heat transfer medium that has dispersed its heat via a heat consumption area to circulate the same to the ground heat exchanger; and a plurality of circulation loops. The medium collector includes first and second reservoirs that are arranged in two tiers: upper and lower, spaced apart from each other, an upstream pump is provided in a first circulation loop between the first and second reservoirs, and the second reservoir is placed higher than the first reservoir. The ground heat exchanger may enhance heat exchange efficiency by increasing the contact area and time between the ground and the heat transfer medium.
