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 ...
