（Patent No：200420083407）
Advantages: Vents on the top of the greenhouse can be opened to its maximum size to discharge the hot air out of the greenhouse easily. Its characteristic of being tightly close to the greenhouse ensures its best
performance of wind resistance.

→Internal Shading System  
Reflecting light by shading system to control the illumination ensures the energy saving and temperature preservation in the greenhouse.

→External Shading System  
In the seasons with high temperature, the external shading system is capable of weakening the light intensity inside the greenhouse so as to effectively lower down its internal temperature.
Two types of external shading system are available, that is single-layer external shading system and double-layer external shading system. There are also two types of retractable systems for the opening and the closing of the nets which are controlled by the gear racks and cables.

→Evaporative Cooling Pad  
External hot and dry air is sucked by ventilator through the wet pad, water absorbs the heat in the air, while the cool and wet air penetrates into the greenhouse and then lower down the temperature insides.
