WebAn orifice tube is used to control the flow of refrigerant into the evaporator. It works in conjunction with compressor controls to maintain low side pressure at a sufficient level, to prevent evaporator icing or flooding. The orifice tube is placed in the high side liquid refrigerant line, at or near the evaporator. WebThere are three type of orifice: concentric, eccentric, and segmental. Dall tube. The Dall tube is a shortened version of a Venturi meter, with a lower pressure drop than an orifice plate. As with these flowmeters the flow rate in a Dall tube is determined by measuring the pressure drop caused by restriction in the conduit.
