Environmental control systems and methods to control environmental temperature of an enclosed space by integrating a passive heat exchange subsystem (e.g., a loop heat pipe (LHP) heat exchange subsystem) having a closed loop heat exchange fluid circuit in heat-exchange relationship with the enclosed space for providing environmental temperature control therewithin, a RAM-air subsystem having a RAM-air circuit for circulating RAM cooling air, and a vapor compression cycle machine (VCM) subsystem having a VCM fluid circuit having a compressor, an evaporator, a condenser and an expansion valve.

Integrated environmental control systems and methods for controlling environmental temperature of an enclosed space

Passive on-board aircraft cooling systems are provided with an evaporator/receiver in heat-exchange relationship with at least one heat source on board the aircraft, the evaporator/receiver containing a liquid phase working fluid which changes state to a vapor phase working fluid in response to heat transfer therefrom from the at least one heat source. First and second condensers are fluid-connected to the evaporator/receiver for receiving vapor phase working fluid from the evaporator/receiver. At least a portion of the vapor phase working fluid transferred to the first and second condensers is condensed by heat transfer between the first and second condensers and aircraft-external unpressurized and aircraft-internal pressurized air supply streams, respectively, to thereby form liquid phase working fluid which returns to the evaporator/receiver by virtue of the fluid connection with the first and second condensers.
