3.1. PRINCIPLE AND AIRFLOW

The well insulated cabinet interior is divided into working and treatment chambers, as shown in the diagram (fig.1). Air is circulated by a fan from the treatment (conditioning) chamber into the working chamber through the right hand wall plenum in which the wet and dry bulb sensing elements are situated in the optimum position for rapid response. The conditioned air passes through the working chamber in a turbulent manner, ensuring minimum temperature gradients, before returning to the treatment chamber through the left hand wall plenum.

All performance tolerances are to within 50mm of the walls of the working chamber. This is the working envelope in which the test load is not affected by heat sources such as fans, heaters or cooling coils.

The temperature and relative humidity of the air are maintained at the conditions set by the operator via the control system. A sloping false roof is fitted to the working chamber to prevent condensation dripping onto the test load. The base of the working chamber is double skinned to prevent hot and cold "spots" forming due to radiated heat/cold from the treatment chamber. If required, the base of the working chamber may be used as another shelf.
