Chiller system including an oil separator and ejector connection

摘要

A chiller system including an oil separator and ejector connection through which an oil is separated from a refrigerant discharged from a compressor at the oil separator, a portion of the refrigerant discharged from the compressor and an oil discharged from an evaporator are rejected by the ejector, and the separated oil and the ejected refrigerant and oil are heat exchanged, and return into the compressor.

主权项

1. A chiller system including an oil separator and ejector connection comprising: a compressor compressing a refrigerant; an oil separator separating the refrigerant and an oil discharged from the compressor; a condenser condensing the refrigerant that has passed through the oil separator; an expander expanding the refrigerant condensed by the condenser; an evaporator allowing the refrigerant expanded by the expander to cool cold water, and connected with a cold-water demand source by a cold water pipe; an ejector connected with the compressor by a discharge pipe-ejector connection channel and connected with the evaporator by an evaporator oil return channel such that a portion of the refrigerant discharged from the compressor and an oil discharged from the evaporator are ejected thereby; an oil separator oil return channel connected between the oil separator and the compressor such that the oil discharged from the oil separator passes and then returns to the compressor; and an ejector outlet channel connected between the ejector and the compressor such that the oil and the refrigerant discharged from the ejector returns to the compressor, wherein the oil separator oil return channel and the ejector outlet channel are disposed such that the oil discharged from the oil separator and the oil and the refrigerant ejected from the ejector are heat-exchanged.
