1. A universal Variable Multi Flow (VMF) system, comprising:
a housing comprising a frame and a plurality of insulated panels;
a fresh air inlet damper configured to regulate an air flow;
a return air inlet damper;
a fresh air inlet filter coupled to the fresh air inlet damper;
a return air inlet filter coupled to the return air inlet damper;
a counter flow plate heat exchanger with a bypass damper configured to extract heat/humidity from air;
at least one supply and at least one return air fan configured to support circulation of the air through the VMF;
at least one condenser/evaporator coil configured to extract heat from ambient air and to serve as a refrigerant circuit;
a supply coil configured to re-cool or re-heat the air in separate enclosed areas; at least one brushless DC (BLDC) scroll compressor configured to produce warm or cold refrigerant;
at least one variable frequency drive configured to control capacity of the at least one BLDC scroll compressor; and
a controller configured to control operations of the entire VMF system.
