Abstract (English):
This article analyzes the effect of overheating the refrigerant in the evaporator on the performance of the theoretical cycle chiller. Equations that permit to calculate the amount of additional work cycle caused by the presence of overheating in the evaporator, according to the thermodynamic parameters of the working fluid cycle and operating parameters values overheating. The analytical dependence of the specific cooling cycle with the overheating of the above parameters.
