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.

A freeze point protection method and system is provided for water cooled chillers. The method prevents freezing of chilled water and damage to the chiller. The method allows the evaporator temperature to drop below a freezing temperature for a predetermined amount of time prior to shutting down the chiller. The temperature of the refrigerant in the water chiller is periodically sensed. The amount of time that the chiller is below a predetermined freezing temperature is periodically counted and compared with a determined maximum time that the chiller may operate at a sensed temperature below the predetermined freezing temperature without damaging the chiller. The method will shut down the water chiller if the counted time exceeds the determined maximum time. A system for shutting down a water cooled chiller to prevent freezing of chilled water is also provided.

An evaporator for use in a vapor compression system is disclosed. The evaporator may include an enclosure that covers a substantial portion of a tube bundle in the evaporator. The enclosure substantially prevents refrigerant vapor, generated as a result of the heat transfer with the tube bundle, from flowing laterally between tubes of the tube bundle. Various configurations of a distributor for distributing refrigerant to at least a portion of a tube bundle in the evaporator provides increased performance of the evaporator.

A level control algorithm for an HVAC refrigeration system is provided. The control algorithm utilizes a fuzzy logic methodology to automatically adjust a flow of refrigerant in the system to maintain a desired liquid level in the condenser. The fuzzy logic methodology incorporates a plurality of fuzzy logic control algorithms each having different membership functions and other control parameters that can provide different degrees of level control in the condenser. A particular fuzzy logic control algorithm is selected based on the amount a measured liquid level in the condenser deviates from the desired liquid level in the condenser.
