Cold-storage facility converted to propane in Colombia.
Asocolflores, the association representing flower exporters in Colombia, has replaced an R22-based system with R290 in a 392 m2 cold storage facility for flowers, located in the Savanna of Bogota.
The performance of the system was analyzed and results showed that R290 provides 10% less of cooling capacity, but increases the Coefficient of Performance (COP) and reduces energy consumption by at least 10%.
To address safety concerns such as system pressure and refrigerant flammability, Asocolfores put in place several measures. In particular, an analysis on flammability based on the EN 378:2008 safety standard for refrigeration systems and a basic risk assessment under EN 1127-1:2011 was achieved.
