SR2023 Oil Return In Refrigeration Systems Teaching Equipment Refrigeration Laboratory Equipment

Learning Objectives / Experiments

– fundamentals of the oil return in refrigeration systems

– effect of the rising pipe diameter on the oil transport

– effect of partial and full load operation on the oil transport

– principle of operation of a double rising pipe

– separate or parallel operation of the compressors

Specification

[1] investigation of the oil return to the compressor in refrigeration circuits with oil soluble in refrigerant

[2] refrigeration circuit with 2 compressors connected in parallel, condenser with 2 fans, evaporator with fan and thermostatic expansion valve

[3] 3 single and 1 double rising pipes from glass in the suction pipe of the refrigeration circuit

[4] rising pipes selectable via valves

[5] Flow rate in the refrigeration circuit adjustable by single or combined operation of the two compressors

[6] fan speed adjustable

[7] thermowells for temperature measurement

[8] refrigerant R134a, CFC-free
