Hot Box Experiment

Before conducting the primary experiments for the RIDER prototype, a series of preliminary tests using a heated climate chamber, referred to as the “Hot Box,” were undertaken to explore strategies for maintaining cooler interior environments under extreme heat. Over three weeks, these controlled experiments simulated tropical conditions, with relative humidity ranging from 50 to 90% and temperatures cycling between day (about 33 to 34°C with 60 to 65% RH and 25 to 27 W/m² radiation) and night (about 24 to 26°C with 90 to 95% RH and no radiation). The cyclical nature of these tests was achieved by alternately activating and deactivating the radiant heat source.
