Based on the data, ozone-depleting substances is Freon, the 2003 ozone hole reached 25 million square kilometers in area, and it hazards human health and ecological environment in many ways. According to the analysis, a decrease of 1% on the stratospheric ozone layer, global 0.6-0.8% will increase the incidence of cataracts, blindness, means it will increase the number from 10,000 to 15,000 people. Ultraviolet radiation, it could be cancer.

Accordingly, by January 1, 2010 will completely prohibit the use of freon. At present, the technique is to use electricity to power air conditioning, indoor heat to be absorbed or emitted into the air outside the circle. This easy to install air-conditioning electricity, air conditioning equipment more and using more power increasingly tense. The lack of electricity constraints the development of the traditional air-conditioning industry. Meanwhile, media freon refrigeration cycle, such as the widespread use of fluoride, lead to the destruction of the atmospheric ozone layer, the deterioration of the ecological environment. Tension has been growing in the world today, using more energy-saving and environment-friendly air-conditioning system is the common needs of humanity. Solar air conditioning'' focus on solving the problem of electricity, instead of using environmentally friendly refrigerant Freon, Freon to the air-conditioned media for the media to be eliminated; You developed a solar electricity and air conditioning to save fuel and reduce the environmental pollution, to name but a green air-conditioning, it is more suitable for the needs of thousands of scattered installation.
