- It is based on the technology of photo-thermal area of solar energy to use the wave property of sunlight; it is used in
.. heating/cooling of and water supply to buildings through the absorption, storage, and thermal conversion of the solar heat.
- The core of the technology to use solar heat consists of solar heat collection technology, thermal storage technology, system
.. control technology, and system design technology.
- Depending upon the existence of the driving device of thermal media, the system is classified into natural type (passive)
.. system and equipment type (active) system.
- The natural type system is applied to collect and use the solar heat with use of the building structures such as the south
.. windows and walls such as greenhouse and trombe walls; the equipment type system is called solar heat system because
.. the solar heat is collected with installation of separate heat collectors and with use of thermal media driving devices such as
.. pumps.
- The system is usually classified into low-temperature, moderate-temperature, and high-temperature systems depending
.. upon the heat collection or utilization temperature.
