TCRCTC Equipamento de Refrigeração com Distintos Tubos Capilares, Controlado por Computador (PC)

The Computer Controlled Refrigeration Unit with Different Capillary Tubes, "TCRCTC", designedby EDIBON, is clearly arranged and represents a typical compression refrigeration system withcompressor.

The main components of the unit are the hermetic compressor, condenser, evaporator, expansionelements, reservoir and a receiver for refrigerant where, refrigerant can be added to or removedfrom the refrigeration circuit.

The unit includes three capillary tubes of different lengths and a thermostatic expansion valve forthe comparison of serveral expansion elements.

The evaporator and the condenser are finned tube heat exchangers. In both exchangers thereare transparent tubes to observe the change of state of the coolant during the evaporation andthe condensation.

An additional storage tank for the refrigerant is included to study the effects of overfilling andunderfilling the system.

The main factors involved in the cycle can be measured: coolant flow, compressor power and pressure and temperature in key points ofthe cycle.

The circuit also includes a sight glass to observe the state of the coolant fluid, a filter, a storage vessel to ensure a proper flow of coolant inthe circuit and a liquid separator to prevent liquid from entering the compressor. As a safety measure, the circuit includes a high pressureswitch and a low pressure switch.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + aControl Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, forcontrolling the process and all parameters involved in the process.
