Controlled blast cell cooling

A method of operating a blast cell system, the method comprising:

• circulating cooling air with one or more cooling fans through a plurality of bays that are each laterally separated from adjacent the plurality of bays so that cross-flow of air between the plurality of bays is prevented, wherein each bay of the plurality of bays has an entrance and an exit;
• measuring, by one more entrance sensors positioned at or near the entrance for each bay of the plurality of bays and one or more exit sensors positioned at or near the exit for each bay of the plurality of bays, differential temperature, differential air pressure levels, or both in each bay of the plurality of bays, wherein the one more entrance sensors and the one more exit sensors each include one or more of:
• pressure sensors, temperature sensors, or both, positioned to sense differential flow conditions between the entrance and the exit for each bay of the plurality of bays;
• determining, from the measured differential air pressure levels, particular levels of the differential air pressure for each bay of the plurality of bays so as to achieve a desired cooling level;
• and modulating open-closed positions of a plurality of louvers associated with respective ones of the plurality of bays during the blast cell system's cooling process based on the differential flow conditions sensed by the one more entrance sensors and the one more exit sensors, wherein modulating the open-closed positions of each of the plurality of louvers allows for dynamic adjustment of air flow through each bay of the plurality of bays, wherein the plurality of louvers for a first bay of the plurality of bays are controlled separately from the plurality of louvers for others of the plurality of bays during the cooling process.

A method of providing a per-bay controllable blast cell, comprising:

• providing one or more fans controlled by a variable frequency drive to serve the blast cell;
• providing full-length baffles between bays in the blast cell that extend from a front end of the blast cell to a back end of the blast cell, to block cross-flow of air between the bays;
• providing one or more entrance sensors positioned proximal the front end of each of the bays and one or more exit sensors positioned proximal the back end of each of the bays and configured to sense differential pressure conditions between the front end and the back end of each of the bays, wherein the one or more entrance sensors and the one or more exit sensors each include one or more of:
• pressure sensors, temperature sensors, or both, positioned to sense differential flow conditions between the entrance and the exit for each of the bays;
• and providing separately-controllable louvers at the front end of each bay of the bays in the blast cell and connecting the louvers to a control system that is arranged to modulate open-closed positions of each of the louvers for a particular bay separately from the louvers for other bays during the blast cell system's cooling process, based on differential flow conditions sensed by the one or more entrance sensors and the one or more exit sensors, taken from respective ones of the bays wherein modulating the open-closed positions of each of the louvers allows for dynamic adjustment of different volumes of cooling air to flow through each respective bay of the bays during the cooling process.
