【Abstract】 The thermo exchanging processes between the inner and the outer surfaces of the glass in a freezer door were simulated with a model of two infinite parallel planes.Low emissivity film coated on the glass can considerable reduce dewing of the glass door of a freezer.The possible anti dewing mechanism of the film was studied theoretically and experimentally.We suggest that it is better to coat the inner surfaces of the freezer door glass with the film,with applicable emissivity ranging from 0.1 to 0.2,to get the energy saving,low cost,and effective anti dewing performance.更多还原
