1. A method of operating a water recovery system comprising:
activating, by one or more processors, a plurality of dampers, a fan, and a refrigeration system of the water recovery system;
measuring, by the one or more processors, an ambient air temperature of the water recovery system using an ambient air temperature sensor;
measuring, by the one or more processors, one or more evaporator temperatures associated with an evaporator of the water recovery system using one or more evaporator temperature sensors, wherein the one or more evaporator temperatures comprises a post-evaporator temperature and the one or more evaporator temperature sensors comprises a post-evaporator temperature sensor;
determining, by the one or more processors, an optimal evaporator air temperature of the water recovery system based on the one or more evaporator temperatures and the ambient air temperature;
comparing, by the one or more processors, the optimal evaporator air temperature and the post-evaporator temperature; and
setting, by the one or more processors, a speed of the fan based on a comparison of the optimal evaporator air temperature and the post-evaporator temperature.
