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.

Capillary tube systems do not stop the flow of refrigerant after the compressor is shut off by the cycling control. In fact, refrigerant will continue to flow from the condenser to the evaporator ...

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 ...

Fill a narrow glass capillary tube with water, then turn it horizontal. Conventional wisdom says that the water will remain inside the tube. But a group of scientists in Spain and the UK has found ...
