How to clean up a reversible installation?
The reversible installation and particularly the heat-pumps are often subject of pollution,principally due to moisture in the circuit. Presence of moisture in a refrigerating installation generate the decomposition of the refrigerant and oil. It causes the formation of organic acids which can create: – The circuit corrosion – The deterioration of the motor’s windings – The formation of sludge – The compressor’s destruction In the case of compressor’s carbonization, and after its replacement, it is not sufficient to change the polluted refrigerant. Indeed, in such a case, it remains inevitably in the refrigerating circuit some acid oil and some residues which have not been evacuated. To resolve such problems, CARLY recommends two types of actions: – a preventive method is to install a bi-flow filter drier, DDCY, and a sight glass, VCYL which allows to control the DDCY efficiency on the liquid line before the startup of the installation. – a curative method is to install a cleaning bi-fl
