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.
The capillary tube has been used as a refrigerant metering device for many decades. Many HVACR manufacturers are still successfully employing capillary tube metering devices in their latest equipment.
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 ...
