An air conditioning system includes a first fan coupled to a first air outlet of a first room, a second fan coupled to a second air outlet of a second room, and a microprocessor controlling a fan speed of the first fan independent of a fan speed of the second fan. The air conditioning system also includes a first control unit and a first sensing unit in the first room, and a second control unit and a second sensing unit in the second room. The microprocessor is configured to adjust the fan speed of the first fan based upon a temperature threshold from the first control unit and a sensed temperature from the first sensing unit. The microprocessor is configured to adjust the fan speed of the second fan based upon a temperature threshold from the second control unit and a sensed temperature from the second sensing unit.

Aspects of the present disclosure describe a multi-layer chiller operation management framework and associated methods for managing heating, ventilation, and air conditioning (HVAC) multi-chiller unit operation in real time serving varying system loads. According to the present disclosure, the framework includes two layers—a first layer providing 24-hour chiller operation planning thereby optimizing chiller operation using forecasted load profiles to minimize energy consumption. To this is applied a mixed-integer linear programming (MILP) based optimization. A second layer adjusts chiller operation status in real-time based on actual system load demand. Load forecasting uncertainty is cured in a hierarchical manner based on the level of load uncertainty. Two approaches are employed namely rule-based load sharing adjustment and MILP-based rolling optimization.

A precision pump system having a motor driver for accurately and repeatedly delivering process fluid, (e.g., photo chemicals) using a pumping fluid with minimal process fluid loss to a fabrication process and whereby the motor driver can be easily and quickly replaced without interrupting the fluid flow path. This is accomplished with the use of a process fluid reservoir and a pumping fluid reservoir that are associated with the pump, either integrated with the pump or closely adjacent. In addition, this precision pump system can be remotely monitored, viewed and controlled over the Internet. In addition, trapped process fluid within a downstream filtering block can be recirculated to the process fluid reservoir when trapped gas in the filter is removed. Furthermore, a nitrogen gas source is connected to the process fluid reservoir via a valve in case a need to insert a gas is required.
