Forced air thermal energy storage system

The system of claim I, wherein the controller is further configured to:

• send a command to the chilled air generation system during the second period of time that activates the chilled air generation system that generates the chilled airflow;
• activate a reversible fan module of the forced air convection system in a first direction during the second period of time;
• send a second command to the chilled air generation system that deactivates the chilled air generation system during the first period of time;
• and
• activate the reversible fan module of the forced air convection system in a second direction during the first period of time.

A system, comprising:

• a facility having an internal area;
• a forced air convection system configured to generate a convective airflow within the internal area of the facility:
• a chilled air generation system for periodically supplying a chilled airflow to the internal area of the facility;
• one or more phase change material (PCM) modules, each comprising a phase change material, wherein the PCM module(s) is(are) configured to exchange heat with air in the internal area;
• and
• a controller configured to determine:
• a first time period or periods during which to operate the forced air convection system;
• and
• a second time period or periods during which to operate the chilled air generation system;
• wherein the controller is configured to determine the respective time periods based on:
• one or more of a temperature of the air within the internal area of the facility, a temperature of a good stored within the facility, or a temperature of the phase change material or the PCM modules;
• and
• a cost and/or availability of electricity from a power supply.
