In Ecuador, there is a large energy consumption by air conditioning and refrigeration in the industrial, commercial and residential sectors. A maximum electricity demand reduction method is to incorporate an optimal cooling thermal energy storage system. The main objective of this work was to develop a parametric study of laboratory ice tube generator for an after optimization. For that, the main parameters were studied, which are: water storage temperature, refrigerant temperature in the evaporator and condenser, ice subcooling temperature and ice formation speed. Two outstanding parameters that intervened in the ice formation process were the place environmental conditions and the water temperature used, when the environmental temperature decreased, thermal load also decreased and condenser efficiency improved, which directly influenced the efficiency of the equipment. The instability observed in the first hour of test intervened in the final water temperature, final temperature ranged from 1.1 ° C to -0.4 ° C in three hours.
