The capillary tube — the simplest of refrigerant controls — is the most popular method for metering refrigerant flow from the condenser to the evaporator in compression-type refrigeration systems.

Capillary tubes are generally used as the metering device on small, fractional-horsepower refrigeration systems. Charging these systems with refrigerant requires a different procedure than those ...

Tube radial distribution chromatography (TRDC) is an innovative separation technique that exploits the spontaneous radial segregation of mixed solvent systems under laminar flow conditions in ...
