1. A system for removing heat from and cooling air in a building, the system comprising:
a modular chilling unit separate from the building for supplying cooled air to the building at a constant rate, the building having a heat containment for capturing or receiving hot air inside the building, the building further having an exhaust structure comprising one or more vents associated with one or more vent fans for expelling the hot air from the building, the chilling unit comprising:
a housing having an intake end and an exhaust end in communication with the heat containment, wherein the intake end is not in communication with hot air downstream of the heat containment;
at least one chilling element disposed between the intake end and the exhaust end to lower the temperature of the ambient air; and
at least one fan positioned in the housing and set to operate at a constant speed to draw ambient air from the intake end of the housing, cool the ambient air by directing air through the at least one chilling element, and direct the cooled air to an opening of the building;
wherein expelling the hot air from the building creates a pressure differential in which an air pressure at a hot side of the building is lower than an air pressure at a cool side of the building;
wherein a desired pressure differential is maintained by controlling the one or more vent fans to maintain the desired pressure differential between the hot side of the building and the cool side of the building based on information from one or more pressure sensors;
wherein the pressure differential draws the cooled air supplied by the chilling unit through the opening of the building from the hot side of the building to the cool side of the building; and
wherein the building has an air conditioning unit that is set to maintain a target temperature and, responsive to a temperature in the building rising above the target temperature and with the chilling unit supplying the cooled air to the building at the constant rate, the air conditioning unit is operable to run until the temperature in the building drops down at or below the target temperature.
