Abstract: In order to study the frost mechanism of horizontal refrigerators with natural convection is analyzed. The frost reducing effect of several frosting modules is simulated by the test method. The optimization scheme of the unidirectional float valve pneumatic control system with hydrophobic melamine foam is determined, and the actual frost reducing effect of different density hydrophobic materials is verified, so as to optimize the frost reduction module. The research direction is provided.
