These seamless tubes are made of copper and act as a throttling valve to meter the amount of refrigerant entering the evaporator. There is only one set of conditions at which a capillary tube will ...

Capillary Tube: A narrow tube which exploits the pressure drop resulting from friction and expansion of the refrigerant, serving as a throttling device in 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 ...

A thermocouple (capillary tube) runs from the switch to the evaporator. Inside the capillary tube is refrigerant in a vacuum. Expansion and contraction of refrigerant against diaphragm spring ...

Get expert advice on improvements to your home, including design tips, how much you'd expect to pay for a pro and what to ask when hiring experts.

As refrigerant leaves the evaporator it goes from a liquid back to a gas to the compressor, ... As evaporator temperature increases, pressure in the capillary tube (also called a thermocouple) ...
