CAP TUBE .036 X 56 W/DRIER TO INCLUDE 1 036 FILT
Capillary action (sometimes capillarity, capillary motion, capillary effect, or wicking) is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity. The effect can be seen in the drawing up of liquids in a thin tube. It occurs because of intermolecular forces between the liquid and surrounding solid surfaces. If the diameter of the tube is sufficiently small, then the combination of surface tension (which is caused by cohesion within the liquid) and adhesive forces between the liquid and container wall act to propel the liquid.
A filter-drier in a refrigeration or air conditioning system has two essential functions: one, to absorb system contaminants, such as water, which can create acids, and two, to provide physical filtration. Appliance driers are usually installed in the liquid line, as close to the metering device as possible. If the metering device is a capillary tube, the outlet of the drier is typically sized to allow brazing the capillary tube into the drier. The screen in the drier is placed far enough away so that the capillary tube can be inserted into the drier without blocking the refrigerant flow into the capillary tube. The position of the drier should be as vertical as possible with the flow in the downward direction. This position will also allow the drier to act as a liquid seal for the capillary tube, to ensure pure liquid refrigerant flow through the capillary tube.
