RADIATION COOLING/HEAT TRANSFER-BASED METHODS, SENSORS AND SYSTEMS FOR FORECASTING AND/OR DETECTING ACTIVE FROST CONDITIONS

摘要

An active frost warning system for the forecasting and/or detection of active frost conditions by determining the rate of radiation heat transfer is provided. The system predicts active frost conditions when the rate of cooling/heat transfer of a sensor suggests items in the sensor's environs will be less than the frost point temperature in the future.
