发明名称 Liquid activated control switch
摘要 A liquid activated control switch for detecting the presence of an excessive accumulation of low ionic strength liquids in an air refrigeration system and for controlling the operation of the air refrigeration system based upon the detection of the accumulated liquid which includes first and second liquid detection probes. When the liquid detection probes detect an excessive accumulation of liquid, the air refrigeration system is disconnected. After the excessive accumulation of liquid has been removed, the air refrigeration system remains disconnected until the switch is reset. Alternative embodiments of the liquid activated control switch prevent sloshing liquid in the vicinity of the probes from rapidly turning the switch on and off, by providing varying degrees of sensitivity to accumulated liquid. Time delays are provided in turning off the air refrigeration system when liquid is detected by the probes, and in turning on the system when liquid is no longer detected.
