Experimental Study on the Effect of R134A Charge Quantity on the Built-in Refrigerator System

Because the refrigerant capacity of built-in refrigerator is small,the change of refrigerant charge quantity in refrigerator system will have great influence on the refrigeration performance. The built-in cabinet experiments are carried out to study the charge quantity. The optimal R134A charge is got on the basis of a variety of factors. By changing refrigerant charge quantity in refrigerator system,the change of refrigeration performance parameters with the refrigerant charge quantity was studied,which provides a certain basis for determining the refrigerant charge quantity reasonably.
