Abstract
The Planck sorption cooler nominal unit was actively tested from 27 June until 7 August 2008. It was tested in two main thermal conditions: beginning-of-life; and end-of-life power conditions. These two cases correspond to input powers of 304 and 470 W, and hot radiator interfaces of 270 and 273 K for the cold and hot cases respectively. For the cold case the last pre-cooling stage (PC3C or V-groove 3 temperature) was 47 K and 48 K for the hot case. Cooler performance is determined by these two interfaces.
