Design, Construction and Testing of a Cold Store With Water-Cooled Chiller

Abstract

Objective of this research was to de-sign, construction and test of a cold store with chiller unit. Dimensions of the cold store were 5x4x3m. Heat load was calculated and capacity of cooling system was determined. Ambient temperature was set 2°C and relative humidity 90% for cold store testing. Am-bient temperature, relative humidity and air velocity were measured for 3 different levels and 12 points for each level in the cold store. Total heat load and capac-ity of cooling system were calculated 6264 kcal/h (7.284 kW). The descriptive statistics were calculated for the ambient temperature; mean, 2.82°C, standard deviation 0.02°C and CV (%) 0.56, and for the rela-tive humidity; mean 88.01%, standard deviation 0.61 (%) and CV(%) 0.70 and for the air velocity mean 0.37m/s, standard deviation 0.22 m/s, CV 33.45 %. Even the air velocity CV was high, the ambient tem-perature and relative humidity variations were eval-uated very good © 2022, Latin American Applied Research. All Rights Reserved.
