| Summary: | 碩士 === 大葉大學 === 機電自動化研究所碩士班 === 95 === The problem of global warming is more and more serious, The problem of global warming is threatenning the future of mankind, the renewable energy of environmental protection is valued.The global warming is carbon dioxide and other glasshouse air to exhaust the Earth atmosphere to cause, tying up the thermal energy of sunlight, causing the permafrost temperature rise. Greenhouse Gas is more many, the permafrost temperature will be more high.Using all of all-new policies, such as high-efficiency energy, renewable energy and economy energy...etc. is the methods which solves a global warming.Much science and technology has already existed early, can use to resolve a world warming a problem.In this experiment, with passive type cooling space structure also match an active type fan, then reach the hot comfort in this space structure to match it
mainly with ISO 7730 with ASHRAE 55 two kinds of standard is basis of the indoor hot comfort(Thermal comfort) equally predicts index sign PMV.(Predicted Mean Vote)This active type fan is also controled with PWM(the Modulation of the Pulse Width, the vein wave width adjusts to change), according to experiment space structure inside it the temperature sensor obtains the quantity of temperature
to be used as adjustment, then make this half passive type cool off the space structure reach efficiency and its comfort that it should have.
