The Refrigeration Unit with Different Capillary Tubes, "TCRCT", designed by EDIBON, is clearly arranged and represents a typical compression refrigeration system with compressor.
The main components of the unit are the hermetic compressor, condenser, evaporator, expansion elements, reservoir and a receiver for refrigerant where, refrigerant can be added to or removed from the refrigeration circuit.
The unit includes three capillary tubes of different lengths and a thermostatic expansion valve for the comparison of serveral expansion elements.
The evaporator and the condenser are finned tube heat exchangers. In both exchangers there are transparent tubes to observe the change of state of the coolant during the evaporation and the condensation.
An additional storage tank for the refrigerant is included to study the effects of overfilling and underfilling the system.
The main factors involved in the cycle can be measured: coolant flow, compressor power and pressure and temperature in key points of the 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 in the circuit and a liquid separator to prevent liquid from entering the compressor. As a safety measure, the circuit includes a high pressure switch and a low pressure switch.
