ABSTRACT:
A test chamber for simulating outdoor environmental conditions including the controlled formation of dew or frost on test objects in the chamber. Air processing equipment connected to the chamber includes two types of humidifying equipment, two types of de-humidifying apparatus, and a heating/cooling system using a secondary heating/cooling fluid which heats and/or cools the air without condensation. A radiative cooling system comprising a chilled black body absorbs heat from test objects to induce dew or frost formation. The equipment is controlled by a microprocessor.
