1. A system for environmental control inside an equipment enclosure comprising:
an enclosure configured to house one or more electronic equipment, the enclosure comprising an inlet and an outlet;
an exhaust fan located in proximity to the outlet or within the enclosure and configured to create an airflow out of the enclosure through the outlet;
a temperature sensor located proximate the exhaust fan and configured to provide exhaust air temperature data;
a first sensor located proximate a supply intake of one of the one or more electronic equipment and configured to provide sensor data associated with air that is supplied to the one of the one or more electronic equipment inside the enclosure;
a fan control unit (FCU) coupled to the exhaust fan, the FCU configured to adjust fan speed of the exhaust fan based on fan speed control data; and
a power control unit (PCU) coupled to the FCU, the temperature sensor, and the first sensor, the PCU configured to:
receive the sensor data from the first sensor;
receive the exhaust air temperature data from the temperature sensor; and
execute a fan algorithm corresponding to a selected environmental control mode of a plurality of operational environmental control modes of the enclosure, wherein the plurality of operational environmental control modes comprise a first mode and a second mode, wherein the first mode defines an outdoor environmental parameter and an internal environmental parameter of the one or more environmental parameters of the enclosure, and wherein the second mode defines the internal environmental parameter and a humidity parameter of the one or more environmental parameters of the enclosure;
determine the fan speed control data based on a result of the execution of the fan algorithm; and
provide the fan speed control data to the FCU based on the sensor data and the exhaust air temperature data to maintain one or more environmental parameters of the enclosure.
