Abstract
The present work is about a development of a simulator of a basic refrigeration system, which works with high evaporation temperature, using R-22 like fluid of the system and a capacity of 18,000 BTU/h. In order to help students to understand better how it works, the circuit is simplified and has some connections that allows measure the pressure and temperature in determined points, where the refrigerant fluid is found in different thermodynamic states, according to the behavior of the system. The collect data shows that the system works, reducing the outlet temperature of the evaporator. Some technical features need to be changed, like the isolation of the evaporator and evaporated fan speed control. Besides that, the recycle of components that once were destined to garbage, make this experimental apparatus a sustainable one. With the purpose of improve the operations and results of this system, it is intended to make use of a natural refrigerant fluid and compares to a synthetic one and replace the capillary tube for an expansion valve.
