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 ...

Capillary tube refrigeration systems are integral components in compact refrigeration and air-conditioning units. These systems utilise a narrow, precisely dimensioned tube to regulate the flow of ...

Dipping a tube into a container filled with water will make the water rise in the tube. This phenomenon is called liquid capillarity. It is responsible for many natural and technical processes, for ...
