1. Field of the Invention

The present invention generally relates to an air conditioning apparatus, and more particularly to a modular solar air circulating and conditioning apparatus.

2. Description of Prior Art

People have increasingly higher demands for energy sources to improve lives and create comfortable environments, since the first time we knew how to make use of the resources of the nature. Thereafter, countries over the world spare no effects on the research and development on energy sources.

In known energy sources, solar energy is inexhaustible, and thus solar high-tech products such as a solar water heater having a heat collector for collecting solar energy to produce hot water and a solar battery using a light-electricity converter to convert sunlight into electric power for supplying the electric power to electric appliances or transportation means are introduced to the market.

An air conditioning system having a solar air conditioning apparatus for collecting solar heat and circulating hot air in a house to warm and regulate the temperature of the house in cold weather is disclosed in R.O.C. Pat.
