ABSTRACT:
An energy-saving device is disclosed which is particularly designed to control the temperature of the refrigerant in an air conditioning or refrigeration unit by evaporating a sprayed liquid on the refrigerant-containing vessels. The device may alternatively be utilized to introduce sprayed liquid into the heated air stream of a hot air furnace plenum to provide humidification. The device includes a temperature probe (24) which preferably comprises a thermistor that is positioned adjacent a control area where the temperature is desired to be monitored. A spray nozzle (38) causes a liquid to impinge upon the refrigerant-containing vessels, or to be evaporated in the hot air stream, to effect pre-cooling of the refrigerant prior to entering the condensing coil, or to effect evaporation of the water in the hot air stream to provide humidification. The output of the spray nozzle (38) comprises a series of bursts or spray cycles whose duty cycle within a predetermined period is determined by the temperature sensed by the thermistor (24). The thermistor (24) forms part of an electronic timing circuit (28) whose output is connected to control the actuation of the spray nozzle' s water supply valve (32) so that the higher the temperature sensed by the probe, the longer the spray nozzle is turned on within the predetermined period.
