Capillary tubes serve as simple, fixed-geometry throttling devices in vapour compression refrigeration systems, creating a controlled pressure drop that drives refrigerant expansion from the condenser ...
The capillary tube is a very popular metering device used on many fractional horsepower refrigeration systems. It is basically a length of very small diameter copper tubing soldered or brazed between ...
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.
