ABSTRACT:
A compression system including a compressor driven by a motor, an optional accumulator, a liquid/gas separator, heat exchangers in the form of a condenser and an evaporator, expansion valves and conduit in the form of piping to connect these components together. The liquid/gas separating means is a lubricant separator, typically a cylindrical horizontal or vertical vessel used in conjunction with a gas compressor. The lubricant separator accepts discharge flow from the compressor which includes a mixture of a “smokeless” lubricant and refrigerant gas in a range of particle sizes forming a fluid stream, separates the refrigerant gas from the lubricant and collects the lubricant for reuse in the compressor. Because the lubricant used in the lubrication system rapidly agglomerates into larger size droplets and does not produce an aerosol, the separator does not require a coalescer element to coalesce aerosol and does not require a manway for serving the coalescer element. The coalescer element is replaced with a more reliable and durable mesh pad to agglomerate the larger sized droplets. The overall size and space requirements associated with the separator are reduced.
