Abstract

A pressure reducer module includes an oil separator configured to receive a lubricant and a refrigerant and to separate the lubricant from the refrigerant. The pressure reducer module also includes a pressure reducer connected to and termed integral with the oil separator. The pressure reducer is configured to receive the refrigerant from the oil separator and to reduce a pressure of the refrigerant.
