Abstract
An environmental control system comprises a working gas circuit including a compressor-expander arrangement and first heat exchange means by which the working gas is conditioned before being passed to second heat exchange means connected in the circuit in heat exchange relationship with an environment to be controlled. The working gas is provided with means for regulating the mass of working gas in the circuit in response to the conditioning demand on the system. One such regulating means comprises an inlet path for admitting working gas to the circuit and an outlet path for removing working gas from the circuit.
