The proposed measurement method they reported, referred to as the scanning radiometer method, utilized a relatively inexpensive off-the-shelf net radiometer to make the measurements.
This method was found applicable for radiant heat gain measurements; however, an infrared imaging technique requires expertise and is much more difficult to use, and the equipment is much more expensive than the net radiometer.
The radiant heat loss from equipment was measured using a Fritschen--type net radiometer mounted on a scanning arm.
During the measurements in 2002, a net radiometer (NR Lite, Kipp & Zonen, Netherlands) was installed 4.
1975) and Thorpe (1978) used eight fixed linear net radiometers deployed along a row in an apple orchard, in order to integrate all-wave radiation absorbed by 1.
This paper describes a device designed to measure all-wave radiation absorbed by the canopy of plant hedgerows and its performance when used in coffee crops, allowing time-space integration of the measurements by using moving net radiometers.
A net radiometer consisting of four sensors--two pyranometers and two pyrgeometers--is used along with a traversing mechanism to measure the net radiant heat fluxes from the luminaires.
To measure net shortwave and longwave radiant heat gains from the luminaires to the conditioned space, a net radiometer is used.
The net radiometer is automatically moved across the scanning area by a traversing mechanism and records 0.
