Abstract:
A vapor compression system (10), also known as a chiller, includes a refrigeration loop and a lubrication loop. The lubrication loop includes a lubrication reclamation system that further includes a still (42) and an ejector (44) to reduce a pressure in the still (42). The ejector (44) includes an input portion (46), an output portion 54 and a vent portion (50). The input portion (46), the output portion (54) and the vent portion (50) are in fluid communication with one another. The vent portion (50) of the ejector (44) is positioned in a vent line (48) associated with the still (42). The still (42) primarily contains a mixture of liquid refrigerant and lubricant. The input portion (46) of the ejector receives liquid or gas at a high pressure and expels the liquid or gas through the output portion (54) at an intermediate pressure. As the input fluid at a high pressure flows through the ejector (44), a low pressure is created at the vent portion (50). The reduction in pressure in the vent portion (50) causes a suction pressure within the vent portion (50) associated with the still (44), resulting in a portion of the liquid refrigerant vaporizing, leaving a higher viscosity lubricant.
