In climate control processes often compression refrigerations are used, in which refrigerants such as R134a or CO2 circulate. In addition, refrigerating-machine oils are in the refrigeration cycle to lubricate the compressor.
Monitoring the oil circulation ratio (OCR) in the refrigerant circuit
Typical applications of the inline concentration measurement with LiquiSonic® are:
- measurement of the oil concentration in the refrigerant for continuous monitoring of the oil circulation ratio (OCR)
- monitoring of the refrigerant concentration in the cooling liquid
- detection of product leakages in the climate control system
