Abstract
An existing environmental chamber for short-term indirect calorimetric studies was re-configured for use as awithin-chamber recirculation unit with a computerized control and data acquisition system, and modified with an in-chamberhumidity control unit to provide 30 to 80% RH. Intake air was pre-conditioned to a specific temperature-humidity state pointand delivered at 20 to 50 standard L/min. Data can be collected from the chamber to a computer via an 8 channelamplifying/filtering unit and an analog-digital converter. The computer also controlled the environmental conditions in thechamber. Over a series of dry runs (without animals), system error for dry bulb temperature varied from 0.2C to 1.1C, with an average error of 0.4C. Average moisture production and CO2 errors were 6.5% and 1.4%, respectively, from aseries of animal tests. All were within acceptable limits for reliable data generation.
