The temperature gradient system for the global warming experiment

摘要

PURPOSE: A temperature gradient system for a warming experiment is provided to experiment on an organism effect due to the rise of the carbon oxide and the temperature of a greenhouse. CONSTITUTION: A tunnel type greenhouse(110) products a temperature gradient environment from an air inlet to an air outlet by using air flow according to solar irradiance. A temperature sensing unit(140) measures the temperature of the air inlet and the air outlet of the greenhouse. A controller(200) controls the air discharge amount by calculating temperature difference measured by the temperature sensing unit.
