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 metering devices are found mainly in domestic and small commercial applications that experience somewhat constant heat loads on their evaporators. These systems also have small ...

The capillary tubes are made for neonates. In neonates, capillary blood samples are desirable over other forms of sampling. This is because frequent blood collection from patients with low blood ...
