Mechanical oil float - W-OLC

Proper oil management is essential to ensure compressor lubrication. .
Protecting compressors from low oil levels, which cause wear on compressor pistons, and excess oil in cooling or air conditioning systems reduces system efficiency by:

• Reduction in heat transfer due to oil coating of the condenser and evaporator walls.
• Oil does not change state from liquid to gas and is not a coolant.
• A minimal amount of oil flowing through the system is necessary to provide lubrication for the valves.

In systems that use parallel compressors, a low-pressure oil management system is used. This system consists of three main components: an oil separator, an oil reservoir, and an oil level regulator. The system is designed to allow joint discharge from the compressors to the oil separator, thereby increasing the efficiency of oil separation before it passes to the condenser.

A critical addition to this system is the use of pressure valves to maintain constant pressure in the oil reservoir, which improves the oil return process. Oil floats play a vital role in maintaining the proper oil level in each compressor, opening to feed oil when levels drop and closing when levels are sufficient.

The W-OLC controls the oil level in the compressor oil sump with a float, thereby maintaining the oil level at the compressor manufacturer's recommended level.
