Abstract: Systems and methods are disclosed herein for fluid-dynamic isolation of actively conditioned and return air flow in unconstrained environments. In some embodiments, a system for fluid-dynamic isolation of actively conditioned and return air flow in an unconstrained environment includes: a heat pump subsystem configured to create a conditioned air circuit; and an air curtain subsystem configured to create an air curtain air circuit that isolates the conditioned air circuit from an environment that is external to the system. In this way, conditioned air can be provided in spaces that were impractical before. In addition, this might be done in an efficient way.
