US 2014/0109603 A1 · INTEGRATED ENVIRONMENTAL CONTROL SYSTEMS AND METHODS FOR CONTROLLING ENVIRONMENTAL TEMPERATURE OF AN ENCLOSED SPACE

Abstract

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.

Dependent claims

An environmental control system for controlling environmental temperature of an enclosed space comprising:

a passive phase change 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 second RAM-air subsystem having an air circuit for circulation of cooling air;
and
a third vapor closed loop compression cycle machine (VCM) subsystem having a VCM fluid circuit comprising a compressor, an evaporator, a condenser and an expansion valve, wherein
the evaporator of the VCM subsystem is in operative heat-exchange relationship with the heat exchange fluid circuit of the passive heat exchange subsystem, and wherein
the condenser of the VCM subsystem is in operative heat-exchange relationship with the air circuit of the RAM-air subsystem.
