The Simulation Optimization and Experimental Improvement of the Refrigerator

Abstract:

The Chinese refrigeration industry is faced with dual pressure of energy saving and emission reduction. R600a as an alternative refrigerant of R134a is environment friendly, and the alternation is very good. Firstly, this paper established a two-dimensional steady numerical calculation model of the refrigerating chamber with R600a, and studied the influence of the temperature distribution of the refrigerator’s posterior wall under different schemes on temperature field and velocity field of the refrigerating chamber. When the function of temperature distribution is T=-11.75*y, will achieve the best temperature field and velocity field, and the results are better than the original machine. Secondly, this paper studied the experimental improvement of R600a under the best temperature distribution scheme comparing with R134a.
