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 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 ...

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 ...
