1. A method for ventilating a building comprising:
providing a heating, ventilating and air conditioning system comprising:
an outdoor air intake and an actuator to adjust outdoor air introduced there through,
an outdoor air measurement device associated with the outdoor air intake for determining a quantity of outdoor air entering through the outdoor air intake,
a compressor for cooling air, and
a controller, the controller coupled to the outdoor air measurement device and the outdoor air intake and configured to control the outdoor air intake to allow a prescribed amount of outdoor air to enter there through;
estimating a first duty cycle of the compressor to arrive at a first estimated duty cycle of the compressor;
determining a first desired airflow rate through the outdoor air intake based on the first estimated duty cycle of the compressor and a required continuous outdoor air flow rate;
adjusting the outdoor air intake using the controller to set the first desired airflow rate through the outdoor air intake; and
running the compressor and a fan for a first time interval.
