Changes of State in Refrigeration Circuit
Model: IRC-1904
Changes of State in Refrigeration Circuit (IRC-1904) is a demonstrative refrigeration study unit designed to clearly illustrate all the key stages of a compression frigorific cycle, including condensation and evaporation phenomena. The unit features a front panel with a mimic diagram and instrumentation that allows the most important thermodynamic quantities to be monitored, making it easier for teachers and students to understand the refrigeration cycle. The equipment is supplied with manuals covering the components, setup, operating procedures, and experiment activities with outcomes.
A key feature of the apparatus is that it enables students to observe how the cooling fluid affects the glass realized condenser and evaporator. The compression work is performed by a piston-type hermetic compressor. The evaporating and condensing fluid is network water, while the cooling fluid is R141b, selected for its good thermodynamic properties and high safety degree. A manual micrometrical valve provides cooling gas isenthalpic expansion, allowing students to verify the effect of expansion on the thermal balance of the cycle. The integrated instrumentation enables continuous monitoring of the main operating parameters, while the full synoptic panel provides quick comprehension of the frigorific cycle.
