Abstract

See full text

A temperature control system and method for maintaining the temperature of air within an air pressure controlled enclosure at a desired temperature. The system uses an energy flow model to determine the temperature to which the air supplied to the enclosure must be heated to attain the desired temperature within the enclosure. The energy flow model determines the desired supply air temperature based on the temperature and flow rate of the supply air, the current temperature of the air in the enclosure, the heat transfer rate within the enclosure, and the temperature and flow rate of make-up air entering the enclosure.
