1. A system for providing simultaneous independent temperature control of conditioned air to first and second rooms, the system comprising:
a compressor adapted to circulate a heat transfer medium;
a condenser;
a first flow path through which the compressor is adapted to circulate at least a first portion of the heat transfer medium, said first flow path comprising:
a first circuit of the condenser;
a first expansion valve;
a first evaporator through which air from the first room is adapted to pass before exhausting back to the first room; and
a first circulation valve;
a second flow path through which the compressor is adapted to circulate at least a second portion of the heat transfer medium, said second flow path comprising a second circulation valve and/or a second circuit of the condenser,
wherein, from an outlet of the first circuit of the condenser to an inlet of the first evaporator, the first and second flow paths are fluidically isolated from one another;
a first configuration, in which the first circulation valve is closed to prevent, or at least reduce, circulation of at least the first portion of the heat transfer medium from an outlet of the compressor and through the first flow path, including the first circuit of the condenser, the first expansion valve, and the first evaporator, and back to an inlet of the compressor; and
a second configuration, in which the first circulation valve is open to permit circulation of at least the first portion of the heat transfer medium from the outlet of the compressor, through the first flow path, and back to the inlet of the compressor.
