REFRIGERANT FLOW CONTROL DEVICE

摘要

A simple flow control device is provided in a condensate drain pipe (11) to prevent the flow of refrigerant vapor theretrough and to regulate the flow of liquid refrigerant as a function of the level of accumulated liquid refrigerant in the drain pipe (11). The only moving part is a float device (28) that rides up on a cylindrical valve body (27) in response to the level of liquid refrigerant to thereby expose slots in the valve body (27) which allow for the flow of liquid refrigerant to the refrigerant return line (22) to the cooler.
