Abstract: Forced convection heat transfer is used in the air-cooled refrigerator to make the air in the storage room flow through the evaporation room for heat and moisture exchange, and maintain the temperature of each storage space in the set range through the air circulation in the box. Takes the Indian market as the breakthrough point, combined with the local economy, environment and culture, to explore the market users' demand for flexible storage of food (such as fast ice making, energy saving, fast cooling, convertible, etc.). Especially in view of the fixed problem of the existing two door refrigerators in the market, based on the traditional function of air-cooled refrigerator, an innovative design scheme is proposed, which can realize the function of freezing to refrigeration, and at the same time can meet the rapid cooling. Through the simulation of air circulation and data analysis, a new function of air-cooled refrigerator with double fans is designed.
