SPATIAL VARIABILTY OF AMBIENT TEMPERATURE, RELATIVE HUMIDITY AND AIR VELOCITY IN A COLD STORE
2006, 7 (1) p. 101-110
Abstract
Spatial distribution the ambient temperature, relative humidity and air velocity were determined for different storage temperatures such as 0 oC, 1 oC, 2 oC and 3 oC in an experimental cold store. Mapping software were used to show the variability. Spatial distribution of the temperature and the relative humidity was not uniform in the cold store. Reason of bad spatial distributions was bad spatial distribution of air velocity distributed by evaporator. A temperature and/or a relative humidity sensor are used in cooling systems to measure temperature and relative humidity. The umber of sensors are not enough to determine variability of temperature and relative humidity. There should be additional sensors located different places to give idea for cold storage.
