Abstract：
:The construction and performance of a 5.4 m3 combined direct and indirect calorimeter for human subjects is described. The calorimeter was constructed for studies on human subjects primarily undergoing fast alterations in heat production and heat losses, e.g. after a meal or during physical exercise. A heat sink and a heat substitution principle is used to measure sensible heat losses directly. Evaporative heat losses are determined by measuring water vapour input and output. Indirect calorimetry is performed by measuring output air flow and changes in gas composition of the air entering and leaving the calorimeter. The response times (90%) for sensible heat and evaporative heat were found to be 4 min and 34 min, respectively. Three alcohol combustion tests gave a recovery of CO2 and O2 in the range 92-97%. The recovery of water was found to be in the range 56-89%.
