Capillary Tube Refrigeration. Capillary Tube in ...

The capillary tube is a copper tube of very small internal diameter. It is of very long length and it is coiled to several turns so that it would occupy less space. The internal diameter of the capillary tube used for the refrigeration and air conditioning applications varies from 0.5 to 2.28 mm (0.020 to 0.09 inches).

Capillary tube Refrigeration capillary tube sizing chart

Capillary tube. It is a fixed length of the small-diameter copper pipe, usually with internal diameter from 1/16 to 1/8 inch. It is normally located just ahead of the evaporator, as shown here. Due to its high resistance to the flow friction, it limits, or meters, flow of liquid refrigerant from the condenser to …

fluid dynamics - Capillary tube of insufficient length ...

In the formula for capillary rise only θ is a variable. So when the capillary tube of insufficient length is kept then the θ will change accordingly so that capillary length h comes out to be height of the capillary tube. Limiting case is when θ = 90 degrees when height of capillary tube is 0. This is meaningless so this is not possible.

A Practical Method of Selecting Capillary Tubes for …

Capillary tubes are cheap, reliable and simple to install. But ounce the capillary length and diameter have been selected, the capillary tube can not adjust to load variation in contrast to other expansion devices such as thermostatic expansion valve. There is one point, called balance point, where the capillary tube is at its maximum efficiency.
