1. A modular air conditioning unit, comprising:

  • a base unit selected from a group of base units configured to receive substantially different arrangements or numbers of components;

    a blower configured to be mounted on the base unit;

    an evaporator unit configured to be assembled to the base unit and comprising a housing; and

    a condenser unit configured to be mounted on a top of the housing of the evaporator unit and assembled to the base unit to form a modular refrigeration circuit, wherein the condenser unit comprises;

    a housing comprising a top panel having louvers disposed therein, a bottom panel having a distribution grid disposed therein, a first side panel, and a second side panel, wherein the housing encloses an inner chamber;

    a divider disposed within the inner chamber and configured to separate the inner chamber into a first chamber and a second chamber, and to thermally isolate the first chamber from the second chamber;

    a first condenser coil disposed in the first chamber;

    a second condenser coil disposed in the second chamber;

    an input fan disposed in the first side panel and configured to draw air from a surrounding environment into the first chamber to establish a first airflow path through the first chamber, through the first condenser coil, and through the louvers in the top panel; and

    an output fan disposed in the second side panel and configured to draw air from the evaporator unit into the second chamber to establish a second airflow path through the distribution grid, through the second condenser coil, and through the second side panel.
