Thermoelectric Air Conditioning [PDF]
International Journal of Trend in Scientific Research and Development, 2019 We know that the present air conditioning system produces cooling effect by refrigerants like Freon, Ammonia. Using this refrigerants can get maximum output but one of the major disadvantages is harmful gas emission and global warming. This problem can be overcome by using thermoelectric modules Peltier effect air conditioner and their by protecting ...
